NYC Weekend Weather – Nov 10, 2017

NYC, Rain, Weather Update, Weekend, , , , , , , , , ,

Get ready for record-breaking cold and a blast of deep winter tonight. The cold spell slowly abates over the course of the weekend, but even by Monday, high temperatures are still anticipated to be below normal for this time of year. There is a chance for precipitation on Sunday night with the passage of a weak disturbance.

Rest of today – we’ve already reached today’s daytime high of about 40°F and temperatures will be falling throughout the rest of the day. An arctic front is passing over us now, in its wake, strong cold advection (transport) is ongoing as a continental polar airmass from northern Canada dives down into the area. A high pressure center over Minnesota is also creating a fairly strong pressure gradient with a low pressure system in central Quebec. This will result in breezy conditions with winds from the northwest at around 25 mph and gusts over 40 mph. Wind chill values will fall from the 30s into the 20s.

Strong cold advection is ongoing behind the arctic front. Temperatures are dropping by as much as 2.5-3°F per hour in the Northeast.

Saturday (Veterans Day) – overnight lows going into Saturday are forecast to plummet to record-breaking levels in the low-20s. The high pressure pictured above will be moving closer to us, decreasing the pressure gradient and reducing the winds here. Temperatures should top out around 40°F with lots of sun. It will be a chilly, but sunny day for the Veterans Day Parade.

Sunday – temperatures continue to warm into the upper-40 with increasing clouds.

Monday – some uncertainty exists about the possibility of precipitation overnight into Monday. High temperatures will finally be approaching normal for this time of year with highs in the low-50s and mostly cloudy skies.

This weekend’s weather will be a tale of contrasting temperatures and airmasses. The week ends with warm temperatures more than 10°F above normal. A cold front sweeps through and fall returns for the weekend itself, but another warm up takes place leading into Monday. Also, Daylight Saving Time ends at 2AM Sunday.

Rest of today – increasing clouds for the day. Warm with high temperatures in the mid-70s. Yesterday, a warm front pushed through, putting us in the warm sector associated with a low pressure now over northeastern Quebec.

Saturday – quite a different feel tomorrow once this cold front below moves through the area. Winds will become onshore from the east, bring much cooler air. High temperatures are expected to top out only in the upper-50s with sunny skies (around normal for this time of year).

Sunday – there’s a chance of showers overnight Saturday into Sunday associated with the next storm system to impact the area. An advancing warm front is expected to bring light, stratiform rain ahead of it. Temperatures will be warmer, in the mid-60s with mostly cloudy skies.

Monday – the familiar pattern of warm front followed by cold front continues Monday. We’ll again be in the warm sector with temperatures peaking at about 70°F. Rain should accompany the passage of this cold front.

NYC Weekend Weather – Oct 27, 2017

NYC, Rain, Weather Update, Weekend, , , , , , ,

The weekend starts with beautiful, sunny, fall weather. We see a slight warm up but this will be accompanied with rounds of rain beginning overnight Sunday going into Monday. Temperatures return to normal levels to start the week.

Rest of today – sunny with high temperatures in the low-60s.

Saturday – sunny and slightly warmer with temperatures in the upper-70s. Robust southerly flow ahead of an advancing cold front associated with a weakening low pressure system will push warmer, and more moist air over the region.

Sunday – this southerly winds will set the stage for a wet and windy Sunday. As the cold front nears and lift is maximized, we could even get a shot at some thunderstorms. Winds should be in the 15-20 mph range with stronger gusts over 30 mph. Temperatures will remain in the upper-60s. We could pick up between 1-2 inches of rain.

Monday – a tropical system currently offshore of Nicaragua will likely get picked up by this long cold front mentioned above. As it moves north along the frontal boundary, it will provide a reinforcing shot of energy to the dissipating low. Rain could still be ongoing at the outset of the day as a result, though it should taper off fairly quickly as this storm system moves off east. Temperatures will be on the cool side, with winds shifting to the north behind this storm system. Highs only in the upper-50s.

High pressure continues to exert its influence over the region through the weekend and into the beginning of next week. Temperatures will be quite mild and about 10°F above normal for this time of year. Ideal viewing conditions exist for the Orionid meteor showers.

Rest of today – sunny and mild with highs in the low-mid 70s despite northwest winds.

Saturday – similar setup as today. Sunny with highs in the low-mid 70s. Winds shift to the south as high pressure moves east and offshore.

Thanks to this persistent area of high pressure over the eastern US, we’ve a long bout of sunny and dry weather that continues through the weekend.

Sunday – mild and mostly sunny with high temperatures again in the low-mid 70s.

Monday – increasing clouds and slightly warmer with highs in the mid-70s. We’ll be in the warm sector ahead of an advancing, slow-moving frontal boundary. This feature will bring our next and much needed chance at precipitation into Tuesday.

Orionid meteor showers
These will be peaking over the weekend. Look towards the constellation Orion during the overnight hours with best conditions at around 2AM. Astronomers are expecting a peak of 15-20 meteors per minute radiating from this constellation. The meteors are actually fragments of Halley’s comet, which approaches perihelion (closest pass to the sun) next in 2061. If you’re lucky enough to get away from light pollution, you won’t have any moonlight to contend with either. Sky conditions will be ideal this weekend.

NYC Weekend Weather – Oct 13, 2017

NYC, Rain, Weather Update, Weekend, , , , , ,

This weekend brings a mixed bag of weather, with some chances for rain, but warm temperatures as well. A stark contrast in temperatures marks the beginning of next week with some of the coldest temperatures we’ve seen up to this point in the season.

Rest of today – partly sunny to mostly cloudy with seasonable highs in the mid-60s

Saturday – an inverted trough attached to a low pressure center well south of us rotates into the area and looks to remain stationary during the day. This could bring some scattered showers, however, this trough isn’t particularly strong and a washout isn’t anticipated. In fact, some sun could break through later in the day which could send temperatures higher than the forecast range in the mid-70s.

 

Sunday – temperatures continue pushing well above normal into the upper-70s and near 80°F. Warm air will be flowing in advance of a cold front that will drape across the country.

Monday – that cold front brings a chance of rain overnight into Monday and also ushers in much cooler air. High temperatures drop back into the low-60s. Overnight into Tuesday we might be seeing low temperatures in the upper-40s!

NYC Weekend Weather – Columbus Day – Oct 6, 2017

NYC, Outside of NYC, Rain, Thunderstorms, Tropical/Hurricanes, Weather Update, Weekend, , , , , , , , , , , , , , ,

The first half of this long weekend will continue the warm summer feel we’ve had since mid-week. Some much needed rain arrives Sunday going into next week in conjunction with the anticipated remnants of Tropical Storm Nate. This does literally mean that it will rain on the Columbus Day parade.

Rest of today – mostly sunny. Warm with highs around 80°F.

Saturday – partly sunny, not a bad day though with high temperatures in the low-80s. The stationary front depicted above that’s sitting close to the city will push north of us as a warm front. This will open the door to an increasingly tropical feel with higher dew points and more moisture in the air.

 

Sunday – mostly cloudy. Rain chances increasing in the afternoon with thunderstorms possible. Rain that develops could be heavy with tropical moisture flowing into the area. Still warm, with temperatures in the low-80s. An advancing cold front will push up precipitation partially fueled by Tropical Storm Nate (which is anticipated to make landfall on the New Orleans/Mississippi coastal area this weekend. This precipitation will be moving in on our area well in advance of the actual core of the remnants of Nate.

Monday (Columbus Day) – rain and thunderstorms as the bulk of the remnants of Nate move into the area. Rain heavy at times. Cooler with highs dipping into the mid-70s. With Nate approaching to the southwest of us, we should see more steady rain and clouds, keeping temperatures suppressed.

 

Tropical Storm Nate

Tropical Storm Nate is expected to strengthen into a minimal hurricane after it crosses near or over the northeastern Yucatan Peninsula this weekend and into the Gulf of Mexico. From that point, it’s expected to accelerate towards the Gulf Coast and make landfall in the vicinity of New Orleans, the Mississippi Delta and coastal Mississippi. Even though this storm will pale in comparison to Irma and Maria, it has already claimed 20 lives in Central America due to heavy rains and flooding.

 

NYC Weekend Weather – Sep 28, 2017

NYC, Thunderstorms, Weather Update, Weekend, , , , , , , , ,

This weekend kicks off a stretch of cooler, drier, true-to-form autumn weather after last week’s decidedly summer-like days. A low pressure center over the Great Lakes will slide southeast towards the region to start the weekend. This could scattered showers and thunderstorms. Aside from that, conditions will be dry and fair for the remainder of the forecast period.

Rest of today – high temperatures right about 70°F with sunny skies, much drier feel to the day.

Saturday – scattered showers and thunderstorms possible, especially early. High temperatures in the upper-60s, cooler in spots that see rain.

Sunday – sunny, high temperatures again around 70°F. High pressure from Canada behind the low pressure above will keep things dry and cool for much of the next week.

Monday – slightly warmer, high temperatures in the low-70s, again mostly sunny.

NYC Weekend Weather – Hurricane Maria – Sep 22, 2017

NYC, Storms, Tropical/Hurricanes, Weather Update, Weekend, , , , , , , ,

We have a superb weekend of weather coming up. Temperatures will be anomalously warm for this time of the year, with highs ranging in the mid-upper 80s. It will feel more like late July than late September. Excellent beach weather, if not for the continuing coastal impacts of Jose. The warm spell continues into next week. Our eyes turn towards Hurricane Maria, which after devastating Puerto Rico and Dominica, is now heading up the East Coast. Maria is not expected to make landfall, but it could still bring coastal impacts like Jose.

Rest of today – partly sunny with high temperatures around 80°F.

Saturday – mostly sunny, very warm, temperatures 10-15°F above average for this time of the year.

Sunday – high pressure remains in place with lots of sun and high temperatures again in the upper-80s.

Monday – sunny, temperatures in the upper-80s yet again.

 

Hurricane Maria

You can now see both Post-Tropical Cyclone Jose and Hurricane Maria in the same satellite image of the continental US. Because Jose has eroded the high pressure over the northwestern Atlantic, Maria will have a path to move northwards up along the East Coast. It does look like Maria will get picked up by a frontal boundary late in the week that pushes it out to sea though.

NYC Weekend Weather – Hurricane Irma Update, Sep 8 2017

NYC, Outside of NYC, Tropical/Hurricanes, Weather Update, Weekend, , , , , , , , , ,

We’ve got a wonderful stretch of below average but sunny, fall-like weather ahead of us over the weekend. The main weather story lies far to our south as Florida braces for Hurricane Irma over this same time period. Irma has weakened a bit but is still a large and dangerous Category 4 storm capable of wreaking havoc over the entire state of Florida.

Rest of today – our weather will be dictated by an area of high pressure anchored over the Great Lakes. This will give us mostly sunny skies with a cool high in the mid-70s.

High pressure firmly in control of the weather in our part of the world. You can see Hurricane Irma making its finally approach on Florida in the lower right.

Saturday – sunny with temperatures in the low-70s as the high pressure over the Great Lakes moves east a bit.

Sunday – more of the same as Saturday with sunny skies and high temperatures in the low-70s.

Monday – slightly warmer with high temperatures creeping back into the mid-70s with some more clouds.

 

Hurricane Irma a Major Threat to South Florida

Current Situation

Hurricane Irma has been weakening in the last 12 hours. It’s evident the storm is undergoing an eyewall replacement cycle, where the inner eye of the storm collapses and is replaced by a larger, outer eye. During these internal cycles, max wind speeds often decrease and fluctuate before the storm consolidates a new eye. It has been downgraded to a Category 4 storm with maximum sustained winds of 150 mph.

Headlines

  • Landfall somewhere in South Florida over the weekend is a near certainty. Outer bands from Irma are expected to reach South Florida overnight tonight. Life-threatening storm surge inundation and damage from winds of major hurricane force (115 mph) are a near-certainty for parts of South Florida.
  • Since midday yesterday, forecast models have trended slight back towards a westerly solution for the forecast track of the storm. This almost eliminates the risks to Georgia and South Carolina coastal areas from a direct hit from a major hurricane. However, the risk to these areas from storm surge and strong tropical storm force/marginal hurricane force winds still exists.
  • There is still a chance Irma could make landfall on Cuba. This would weaken the storm ahead of subsequent landfall on Florida.

Forecast Track

As mentioned above, the best performing forecast models have shifted back to a more westerly track for Hurricane Irma.

Several different forecast models take on Irma’s track.
Official National Hurricane Center forecast as of 8AM today.

Forecast Intensity

While Irma has weakened to a Category 4 storm due to an ongoing eyewall replacement cycle, it remains an extremely dangerous storm with an expanding wind field due to this cycle. Hurricane force winds extend 70 miles on each side of the eye and tropical storm force winds well beyond that. It remains possible that Irma can re-strengthen if it completes the eyewall replacement cycle before it interacts with land. Mid-level wind shear remains negligible and Irma will soon be passing over very warm seas with increasing depth. Both of these factors would suggest it maintaining Category 4 strength or possibly re-intensifying to Category 5.

Uncertainties

  • Any landfall on Cuba or interaction of the core of the storm with the high mountains of that island would disrupt the storm and cause weakening. This would be good news for Florida, at the expense of Cuba of course.
  • Should the core of the storm avoid Cuba and close off a new eye before too much time elapses, it would have the possibility of re-strengthening before landfall. A strong Category 4 or even a Category 5 storm making landfall on Florida is not out of the question.

NYC Labor Day Weekend Weather, Eyes on Irma – Sep 1, 2017

NYC, Storms, Tropical/Hurricanes, Weather Update, Weekend, , , , , , , , , , ,

It will definitely feel like the end of summer this weekend as temperatures will be much below average for this time of the year. The remnants of Harvey are also likely to put a damper on weekend activities Saturday night through a decent chunk of Sunday. Labor Day Monday itself looks like a gem. In the long term, I’m keeping tabs up Hurricane Irma, which worries me with its potential to affect the East Coast.

Rest of today – cool, with a Canadian high pressure center to our north-northwest, we’ll feel a refreshing north wind that will diminish through the day. High temperatures are only forecast to hit 70ºF or so even with sunny skies, 10ºF+ below normal for this time of year.

Saturday – temperatures remain cool in the uppper-60s with an easterly onshore flow ahead of an approaching warm front associated with the remnants of Harvey. Overrunning clouds will move in before rain chances build up overnight.

Sunday – rain lingers into the day on Sunday before ending by the afternoon. Mostly cloudy with temperatures in the mid-70s as we get some warmer return flow behind the storm with high pressure setting up to our southwest.

Monday – the warming pattering continues with highs returning to around normal in the low-80s with sunny skies. This is the best day for your holiday weekend grilling, and should be excellent viewing conditions for the annual West Indian Day Parade and carnival.

 

Hurricane Irma – possible threat to the East Coast?

We’ve entered the peak of the hurricane season and right on the toes of Harvey we have Hurricane Irma which put on an impressive display of strengthening the last couple days wen it went from a tropical storm to Category 3 major hurricane. It’s weakened a slight bit but conditions are still favorable for it re-strengthen into a powerful Category 3 of 4 storm before making an approach on the Lesser Antilles.

What is concerning to me is the storm is forecast to take a jog to the southwest over the weekend. The further south and west this storm gets before it starts the process of curving back out to sea at a higher latitude, the greater the chance that it could impact the East Coast of the US. There is still a lot of time so things could definitely change, but it is worth noting that current forecasts favor a more southerly track, enhancing the risk to us. I’ve seen GFS model runs show the storm make direct landfall on the Mid-Atlantic and Northeast. As of this morning, the GFS backed off of this type of scenario. It does bear watching though.
