NYC Weekend Weather – Jan 8, 2016

Rain, Storms, Weather Update, Weekend, , , , , , ,

With a quiet, though at times very cold, weather week behind us, we look towards a weekend that will bring with it much warmer temperatures along with unsettled weather. Looking into the long term, forecast models are hinting at a possible strong coastal low/Nor’easter hitting the area about 10 days from now. Of course, this far out, forecasts will vary wildly, as has been the case the last week or so with forecast models. However, if the right conditions combine, we could see our first big snow event of the season.

Rest of today – clouds increasing steadily during the day with an approaching storm system. High temperatures about normal in the low-40s.

Saturday – the first portion of a storm system for this weekend moves in during the day Saturday, however, precipitation will be limited during the day due to a lack of significant lift in the atmosphere. Cloudy, with high temperatures in the mid-40s.

Sunday – the bulk of the rain will arrive along with a warm front Sunday. Periods of heavy rain are possible throughout the afternoon, tapering off during the evening hours. Depending on if we get any breaks in the clouds, we could see temperatures approach 60ºF during the day.

Monday – once the the low pressure system above exits the area, pulling through a trailing cold front, temperatures will once again plummet back into the upper-30s with clear skies.

After an absurdly warm start to the winter, we are about to get a dose of proper weather for this time of year. While temperatures this week and the first half of January will still above normal in many cases, they will be considerably cooler than December and be closer to normal than not. This week, we start with a messy and complex storm (the same that spawned deadly tornadoes in Texas and has brought blizzard conditions to New Mexico, and an ice storm to Oklahoma) that affects the area tonight into Tuesday with a mix of rain, sleet, freezing rain, and snow, depending on how far north you are. Yet another round rain and snow further north from the city is possible Wednesday.

Rest of today – seasonably cool with high temperatures only in the low-mid 40s. Increasing clouds ahead of a warm front that will be the focus for the precipitation later tonight. Things get interesting overnight as precipitation begins to spread over the area from southwest to northeast. Near the coast, surface temperatures are expected to remain warm enough (upper-30s) to largely preclude the possibility of significant wintry precipitation, however, sleet could mix in with rain to at the start of this storm before things shift over to all rain. Further west and north will be another story, with areas expecting anything between .25″ of ice to 2-4″ of snow/sleet accumulation before rain starts falling.

Tuesday – as temperatures warm with daybreak, wintry precipitation should transition entirely to rain. Rain is expected to last throughout most of the morning into the early afternoon hours. East winds ahead of the warm front mentioned above will be in the 15-20mph range before shifting to the north. High temperatures in the city are expected to hit the upper-40s to around 50ºF.

Wednesday – we’ll get another shot at rain as the cold front railing the warm front pictured above pushes through late on Wednesday into the overnight hours. Despite increasing clouds, forecasts still call for high temperatures in the low-50s.

Thursday – a lingering chance of rain remains on the backside of the cold front. High temperatures are expected to be about the same as Wednesday near 50.

We get a taste of cool weather this weekend, with high temperatures at or slightly below normal for Saturday and Sunday, before we rebound strongly into much above average and possibly record-breaking warmth once again by mid-week next week. Saturday in particular will be feel quite brisk, with a stiff wind from the west dropping wind chills into the 30s. There could even be a couple snow flurries north and west of the city!

Rest of today – mostly cloudy to partly sunny skies with high temperatures hovering in the mid-50s. Temperatures will fall rapidly to near freezing in the city overnight.

Saturday – the low pressure system that was responsible for the soaking rains Thursday will continue to intensify as it moves over the Canadian Maritimes Saturday. As a high pressure center builds to the south, a tightening pressure gradient will yield stiff winds in the 15-25mph range on Saturday. This, combined with a blast of cold air behind the cold front that passed yesterday, will result in high temperatures only in the low-40s, with wind chills making it feel like the 30s throughout the day. There could be enough instability in the atmosphere to spark a couple flurries over the interior!

Sunday – high pressure will remain in control Sunday, so expect sunny skies, and with the high pressure center closer to us, the pressure gradient will diminish. Winds should likewise calm down, and it will feel considerably less raw with high temperatures in the mid-40s.

Monday – temperatures will jump into the low-mid 50s as the high pressure above moves to our east and return flow of warmer air from the south and southwest begins to take hold.

 

White Christmas? Not a chance.

Looking ahead at the week of Christmas coming up – not only will there be no chance of a white Christmas on the Eastern Seaboard, we could be looking at record-breaking warmth again with high temperatures in the low-mid 60s! The Climate Prediction Center’s 6-10 Day Temperature Outlook and 8-14 Day Temperature Outlook are both strongly confident (> 90% probability) that we will see warmer than average temperatures.

NYC Weather Update – Dec 14, 2015

Temperatures remain very warm to start the week, following a weekend of recording-breaking warm weather this past weekend. However, a true cooldown into temperatures within normal ranges for this time of year (high temperatures in the mid-40s) won’t occur until late this week. When that cool down comes around, we could even be looking at a few snow flurries!

Rest of today – widespread fog has taken hold across the region. Fog is expected to lift by around noon, however, generally cloudy conditions are likely to persist through the afternoon. Warm again with high temperatures in the low-mid 60s – higher if clouds break in any areas inland. Later this evening, we get our best shot at a round of showers and even a couple embedded thunderstorms as a cold front pushes through. Timing for this precipitation looks to be around 8PM this evening.

Tuesday – behind the cold front, skies will clear, giving us a much brighter, but also windier day Tuesday. Still, temperatures remain warm, with highs again approaching the low-mid 60s.

Wednesday – cooler temperatures finally kick in with high temperatures dropping into the mid-50s under mostly sunny skies.

Thursday – a secondary surface low will form over the Southeast, associated with a stronger low pressure that will be over the Hudson Bay area. This low brings us our next chance at precipitation, and will yield a mostly cloudy day, with increasing chances for rain in the afternoon as the day progresses.

NYC Weekend Weather – Dec 10, 2015

The weekend coming up will see some unusually warm weather coming our way. In fact, high temperatures on Sunday may well approach record-breaking territory at 60ºF or even higher. This near-record warm trend won’t last through next week, so definitely take advantage of this weekend for some outdoor activities.

Rest of today – partly sunny with highs in the upper 50s.

Friday – with a warm front passing through overnight, areas of fog may develop early Friday morning. Once the fog clears, we should see mostly sunny skies, and high temperatures will again be in the upper-50s to near 60ºF.
Saturday – temperatures continue to warm into the low-60s on Saturday with partly sunny skies. High pressure firmly entrenched over the Southeast will be the primary driver allowing a surge of warm air to enter our region.

Sunday – we could see record-breaking warmth across the region Sunday, with this high pressure still in control and a cold front approaching from the west, increasing the flow of warm air into the area. High temperatures should easily break 60ºF. If cloud cover is less than currently expected, records are likely to be broken.
Monday – the aforementioned cold front makes its approach across the region, bringing us a good chance at some meaningful rain. High temperatures preceding the cold front’s passage are still expected to be quite warm, near 60ºF.
Short-term Temperature Outlook & El Niño’s Impact
Although temperatures will cool somewhat after the cold front passes on Monday, they will nonetheless remain a good deal above average. Seasonal average high temperatures for this time in December are in the low-40s! Climate Prediction Center’s 6-10 temperature outlook has our region at a near certain probability of seeing above average temperatures.

This coheres well with generally understood impacts of an El Niño winter in North America.

NYC Weather Update – Nov 30, 2015

Freezing Rain, NYC, Rain, Weather Update, , , , , , , ,

We start this week off with cool, but slightly above average temperatures in the upper-40s to around 50ºF. A warm up occurs midweek along with a passing frontal system, then a return back to seasonably cool temperatures takes place to end the week.

Rest of today – increasingly cloudy with high temperatures peaking in the mid-upper 40s.

Tuesday – a warm front approaching from the south will provide for an increasing chance of rain tonight into early Tuesday. Temperatures in some inland areas may support a brief period of freezing rain before transition to all rain occurs early in the morning. Temperatures should reach around 50ºF with periods of light rain.

Wednesday – temperatures will warm into the mid-upper 50s by Wednesday following the passage of the aforementioned warm front and prior to the passage of a cold front. Rain continues in periods throughout the day and begins to taper off late Wednesday going into the overnight hours.

Thursday – once the cold front dives through, winds pick up from the northwest again, and drive temperatures down into the upper-40s to near 50ºF Thursday. Expecting dry and mostly sunny conditions otherwise.

NYC Weekend Weather – Nov 27, 2015

Thanksgiving has given us some spectacular weather to be grateful for, but a cool down is in the cards for the region as we enter this weekend. A cold front will be pushing through the area slowly Saturday, bringing some rain, then colder temperatures as cooler air from Canada filters in behind the front. By Monday, high temperatures will only be in the upper-40s.

Rest of today – increasing clouds later today, but for the rest of the afternoon, warm with record-breaking high temperatures in the low-mid 60s.

Saturday – rain likely later in the day, cloudy with cooler temperatures in the mid-50s.noaad2

Sunday – a lingering chance of showers with mostly cloudy skies and a high near 50ºF.

Monday – cooler, but dry, with temperatures only in the upper-40s.

NYC Weekend Weather – Nov 19, 2015

A soaking rainstorm passes through the area later today and then paves the way for cooler, drier air to take over this weekend. By the end of this weekend, temperatures will only be in the low-50s and even upper-40s going into Monday. Looking ahead, temperatures return to normal ranges in the low-50s next week before another warmup around Thanksgiving. Currently, it looks as though the first week of December will open up with cooler than average temperatures.

Rest of today – cloudy and warm with a steady wind from the southeast. Scattered light rain is occurring across parts of the area now. The heavier rain should begin falling later this afternoon (around the PM rush) as more moisture works its way in from the south and the storm system closes in, providing better atmospheric conditions for rain. The rains are still much needed for most of the Tri-State area (in particular Souther Connecticut and Long Island) that remains in the grip of a moderate drought.

Friday – rain ends overnight into Friday morning. Skies clear rapidly with temperatures topping out in the mid-50s.

Saturday – high pressure builds in behind the frontal boundary that will pass early Friday. This high pressure will shift winds to the west and then northwest, bringing in cooler, drier air from Canada. Temperatures will only be around 50 on Saturday as a result.

Sunday – pretty much a clone of Saturday, mostly sunny skies, cool with highs around 50ºF.

Monday – cooler, with high temperatures that may struggle to hit 50ºF.

This week will feature a mixed bag of warm and cool temperatures, along with a bout of moderate-heavy rain and even a couple thunderstorms associated with a cold front passing through the region on Thursday into Friday. Timing of this frontal passage isn’t 100% certain at this point. However, it is clear that behind this front, temperatures will take a dive into more seasonable ranges in the upper-40s to around 50ºF by this weekend.

Rest of today – clear skies with a high temperature well into the mid-60s. This is due in part to high pressure to our south that’s allowing for warm air to flow in from the west.

Tuesday – quite a different story in terms of temperatures. A backdoor cold front pushes through overnight, leading to a shift in winds to the northeast by tomorrow. This wind pattern favors cooler temperatures as the winds circulating clockwise around a high pressure center over the Canadian Maritimes bring in a cooler airmass. High temperatures will struggle to hit 50ºF in this atmosphere.

Wednesday – temperatures quickly rebound as winds switch back to the south-southeast ahead of a cold front which will be passing through the area sometime late Thursday. Cloud should increase during the day, but enough sun should still get through to get temperatures back to near 60.

Thursday – a mostly cloudy day with periods of rain throughout looks to be the headline for Thursday. Temperatures should warm up nicely into the mid-60s with warm, moist air entering the area from the south ahead of the actual cold front. Periods of heavy rain at times could be accompanied by an occasional thunderstorm especially as the cold front nears.gfs_namer_075_1000_850_thick 2

 

 

 

NYC Weekend Weather – Nov 12, 2015

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

Periods of rain this afternoon give way to drier weather over the weekend as a cold front passes through late today into the overnight hours. Drier weather prevails this weekend, though with the passage of this cold front, gusty northwest winds will enter the region, bringing in significantly cooler temperatures for Saturday. Temperatures rebound Sunday as we enter another period of slightly above normal temperatures.

Rest of today – showers have moved out of the area at this point, but a few scattered showers may still pop up later today. Otherwise, cloudy with high temperatures already peaking around 60.

Friday – mostly sunny with winds from the west in the 15-20mph range, gusts up to 30mph.

Saturday – winds again in the 15-20mph range with gusts up to 30-35mph. Sunny skies, but temperatures well below normal in the upper-40s, highs may not break 50 in the city. With the winds, it will feel like temperatures are in the upper-30s to low-40s.

Sunday – winds finally start subsiding, and temperatures will rebound back to around normal in the mid-50s with sunny skies.

Monday – as the high pressure depicted above begins moving to our east, southwest flow on its backside will bring temperatures back into the low-60s.
