NYC Weekend Weather – Apr 27, 2018

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

A wet end to the week will lead to a better first half of the weekend. Showers could occur again on Sunday, but we’ll once again dry out to start next week. A big shift in weather patterns will take place next week with a dramatically warmer air mass to move into the region. Summer-like temperatures in the low-80s by late next week will be a possibility.

Rest of today – cloudy with high temperatures in the upper-50s and rain. Rain beginning this morning, but tapering off in NYC by late afternoon around 4PM, just before the evening rush. Given the set up of winds from the south flowing over a warm front pushing though, some elevated thunderstorms are possible today.

Saturday – nice day on tap with mostly sunny skies and temperatures into upper-60s. Clouds increase late with the chance of scattered showers increasing overnight as a cold front passes through.

Sunday – lingering rain chance early, with conditions improving later and clouds diminishing. Cooler with highs in the upper-50s in the wake of the cold front above.

The pattern of much below normal temperatures will finally break, albeit slowly, starting this weekend. After a soaker to start last week, and a gloomy, rainy Thursday, it will be nice to see a break from the rain. We won’t get another rain chance until Wednesday of this coming week.

Rest of today – mostly sunny with a gusty northwest wind as high as 25 mph, though sustained wind will be calmer in the 10-15 mph range. High temperatures in the low-50s.

Saturday – high pressure will begin to take firm hold of the weather in the region, yielding sunny weather with warmer temperatures in the upper-50s to near 60°F.

Sunday – another beautiful spring day with bright, sunny skies and temperatures near 60°F.

Monday – sunny, and warmer still with temperatures starting to creep into the low-60s.

Despite it being Friday the 13th, if you were looking for some spring weather, this happens to be your lucky day. With our region in the warm sector of a large storm system far off to the south and west (which will bring severe weather to parts of the Mid-Mississippi and lower Missouri Valleys today), warm air will be surging from the south. This will give us a great start to the weekend, though things will shift dramatically by Sunday as a frontal boundary dances back and forth across the area. Wild temperature swings of 30ºF are possible with a much cooler day Sunday.

Rest of today – despite the cloud cover now, temperatures should still reach well into the mid-70s. Any breaks in the clouds would likely result in highs hitting 80ºF. There will also be a steady southerly breeze with gusts up to 20 mph.

Saturday – temperatures remain quite warm with highs again in the mid-70s. The warm front that swept north through the region last night, which brought the warm air along with it, will retreat south of the area as a backdoor cold front late during the day Saturday. Expect temperatures to drop rapidly after this backdoor cold front passes through – between 10-15ºF within as little as an hour. Increasing clouds will accompany this frontal passage.

Sunday – significantly cooler with easterly onshore winds in the wake of the backdoor cold front passage. This onshore flow off the still cold waters of the Atlantic will result in high temperatures only in the upper-40s. Periods of rain will also occur, especially later in the day with mostly cloudy skies otherwise.

Monday – the backdoor cold front will stall just south of us, then push back north as a warm front again. Temperatures will rise back towards around 60ºF prior to the arrival of a stronger cold front. This will be accompanied by steadier rain and even a couple rumbles of thunder are possible.

We’ll start this weekend off with slightly above average to average temperatures. A pleasant weekend of calm weather is in store, and looks to continue into the beginning of next week. Temperatures will dip a little towards mid-week with the anticipated passage of a cold front.

Rest of today – mostly cloudy with a chance for showers as a cold front passes through today. Temperatures at or above average in the upper-50s.

Saturday – a gem of a day with high temperatures in the mid-upper 50s and sunny skies with high pressure in control.

Sunday – some clouds as a early but it should still shape up to be a decent day as another cold front passes through, this time anticipated to be a dry frontal passage. A touch cooler with high temperatures in the low-50s.

Monday – cooler air rushing in behind the second cold front on Sunday will bring overnight lows only in the mid-30s. As a result, high temperatures will be well below normal Monday in the upper-40s.

Now that we have a record-breaking, snow-making, spring nor’easter behind us, we can finally start to look ahead to better, calmer weather. This weekend may not be entirely free of precipitation and will be colder than average, but it will still be a welcome reprieve. Looking ahead, there’s some chance we could see a true taste of spring with temps nearing the 60s late next week!

Rest of today – decreasing clouds as an area of high pressure starts to make its presence felt. High temperatures in the mid-40s.

Saturday – sunny, high temperatures in the mid-40s but with a chilly feel due to some northerly winds.

Sunday – high pressure breaks down and a storm system passes to our south but results in increased clouds. Temperatures in the low-40s as a result. Small chance for rain/snow possible due to the influence of the storm that hit us this week still stuck spinning out in the western North Atlantic.

Monday – high pressure builds again, yielding a sunny day with high temperatures in the mid-40s.

 

Warmer than Average April?

It’s been a rollercoaster temperature-wise in the Northeast to say the least over the last 3 months. January was bitterly cold and much below average. Then we experienced some record-breaking warmth in February, only to revert back to a colder than average month of March. Looking ahead, there are some signs from the Climate Prediction Center that we could experience a warmer than average April!

NYC Weekend Weather – Mar 16, 2018

An uneventful, though kind of cold weekend is in store for the NYC area. Great news for those of you going out for St. Patrick’s Day festivities. Looking ahead into mid-week next week, we have the potential for yet another nor’easter impacting the region with, you guessed it, the possibility for more snow.

Rest of today – partly sunny to mostly cloudy skies with a high near 40°F.

Saturday (St. Patrick’s Day) – warmer, sunny, with a high in the mid-40s, pretty much ideal conditions for the parade.

Sunday – sunny, high in the low-40s. High pressure will be in control of the area.

Monday – mostly sunny with highs in the mid-40s.

Why Seemingly Unending Conveyor Belt of Nor’easters?

The simple answer: The Greenland Block. You may have heard the term “blocking high” mentioned in regards to the anomalously active and cold weather pattern over the Northeast this month. In essence, what’s happened is that a strong ridge of persistent high pressure has formed over Greenland this month. Very cold air over snow-covered landmasses like Greenland is often quite stable. Colder, denser air, also increases surface pressures.

Cyclonic flow around such an area of strong high pressure can wreak havoc with the polar jet stream – diverting its normal flow around the high. This can (and has in our case) lead to the polar jet diving far to the south, allowing large intrusions of Arctic air into the Eastern US. Jet streams can also enhance storms via upper level divergence, lowering surface pressures. Lastly, the blocking high can slow the normal eastward progression of storm systems, causing storms to linger over areas and extended periods of precipitation and coastal impacts in the case of nor’easters.

The Greenland Block is correlated with an index called the North Atlantic Oscillation. When values of this index are negative, it’s more likely that such a blocking pattern arises. Lucky for us, it appears that we may finally get a break in this pattern towards the end of the month.

This weekend, we’ll be watching for development of yet another nor’easter that could impact the region to start off next week. This would mark the third nor’easter in as many weeks, and put an exclamation point on a very active weather pattern. We also set our clocks forward with daylight saving time overnight between Saturday and Sunday. Enjoy more sun in the evenings!

Rest of today – clods and sun with a possibility for a spot flurry later in the day. High temperatures in the mid-40s.

Saturday – mostly sunny with high temperatures around average for this time of year in the mid-40s.

Sunday – another average day with sunny skies and high temperatures in the mid-40s.

Monday – things could get interesting as a developing low off the North Carolina coast works its way up the Eastern Seaboard. There’s a good deal of uncertainty at this time about the eventual storm track. Some models take this storm too far offshore to affect us, but notably the GFS has been on the western end of the forecast envelope. Some of its solutions would bring another significant storm with the possibility for more snow to the area Monday. Needless to say, this is situation that will bear monitoring over the weekend. High temperatures Monday will be impacted by the proximity of this storm. For now, forecasts call for a high around 40ºF with a chance of rain/snow.

March arrives as a roaring lion this year with a powerful nor’easter impacting the region during the first half of the weekend. A variety of hazards from snow to high winds to coastal flooding will affect the area before this nor’easter meanders its way out to the open ocean. Behind this storm, the large scale pattern shifts and much cooler air rushes in, displacing unseasonable warmth with more average temperatures for the week to come.

Rest of today – rain and snow mixing. Little to no accumulation expected. Winds increasing from north to northeast winds 20-25 mph to 30-35 mph with gusts as high as 60 mph near the coast possible later today. Moderate coastal flooding possible over multiple tide cycles tonight, and Saturday. These tides will be higher than normal since they are falling on the full moon (spring tides). Temperatures will hold steady in the upper-30s.

Overnight, an inland low and coastal low consolidated offshore of the Northeast and the coastal low has already rapidly strengthened to a minimum pressure of 984 mb this morning. Two branches of the polar jet have phased together, providing the energy for this robust storm. As the storm continues to deepen, the pressure gradient between it and an area of high pressure over the Upper Midwest will continue to increase, leading to stronger winds. Onshore flow of these winds from the north and northeast over an extended period of time are expected to bring coastal flooding. Periods of moderate to heavy rain could lead to flooding in general. Although the cold, northwest flank of the storm as it exits to the east will support snow (with its cold conveyor belt), accumulations at the coast should be limited. This is another story inland where heavy snow is expected in the Lower Hudson Valley.

Saturday – periods of moderate to heavy rain with snow mixing in continue overnight, but should taper off by the morning. Winds will diminish from the 30 mph range with gusts up to 55 mph overnight but will remain stiff in the 20-25 mph range from the north. Much colder feel with highs in the mid-40s under partly sunny skies.

Sunday – much nicer day, winds finally abating with high temperatures in the mid-40s and mostly sunny skies.

Monday – sunny, with high temperatures in the mid-40s.

A wet and unsettled weekend is coming up for NYC after a week that saw record-breaking warmth and large temperature swings. Back-to-back mid-latitude cyclones with their attendant warm and cold fronts will move through the area bringing a cloudy, gloomy feel, and plenty of chances for rain.

Rest of today – multiple rounds of rain showers possible through the morning and afternoon hours ahead of a warm front advancing from the southwest. Rain chances diminishing after around 6PM this evening. Overcast otherwise with a high temperature in the low-40s.

Saturday – overnight temperatures warming due to warm advection ahead of that warm front. We’ll end up in the warm sector of the first of these two mid-latitude cyclones on Saturday with high temperatures rising into the mid-upper 50s under mostly cloudy skies. Some chance for a scattered shower more likely later in the day as some post-frontal rain develops with a cold front exiting to the east.

Sunday – slightly cooler, high temperatures in the upper-40s. Another cloudy day, with rain continuing from overnight Saturday as first a warm front then a cold front moves through with this second storm system.

Monday – finally a dry day with mostly sunny skies and high temperatures in the mid-50s after this chain of storms!

This holiday weekend will feature some wild swings in temperature. We’ll bookend the weekend with chances for rain, but in between, we may see some decent accumulating snow. So much for an early spring.

Rest of today (Lunar New Year) – the year of the dog arrives on a cloudy day with temperatures dropping through the course of the day on the heels of a couple cold fronts pushing through. We have a break in the rain right now, but more will arrive later in the day. Winds turn to the northwest behind the front and increase in speed, bringing in a much colder air mass that will set the stage for snow on Saturday.

Saturday – much colder with temperatures topping out around 40°F after a very cold start. Increasing clouds as an area of low pressure developing off the Mid-Atlantic coast brings us the chance for accumulating snow. This coastal storm should be fairly fast mover, but forecasters think it will still bring enough precipitation to warrant a winter storm watch. The official forecasts are calling for a range of 4-8″ overnight Saturday into Sunday. Based on current forecast ensembles, I’m inclined to side with the lower end of that range and call for 4″ at best. As usual, the exact timing and track of this storm could still change a bit before the actual event. A slightly slower or slightly more northerly track would result in higher totals, and conversely a faster and more southerly track would result in only minor accumulations.

Sunday – warmer with high temperatures in the mid-40s and decreasing clouds. Whatever snow we get will begin to melt almost immediately.

Monday (President’s Day) – warmer still with high temperatures in the low-50s and chances for rain as a warm front approaches.
