NYC Weather Update – Feb 02, 2016

The calendar says it’s February, but you’d be forgiven for thinking otherwise with temperatures soaring well into the upper 50s this afternoon. The warm trend continues through the middle of this week, when a potent storm system that will be bringing blizzard conditions to some parts of the Midwest (including Iowa, where caucus turnouts may be adversely impacted) passes through the area. Looking ahead, a cool down is on the way, as is the potential for another coastal storm on the day after the Super Bowl. At this time, thermal profiles are not looking conducive for snow, but as we all saw from the last storm, things could very well change as this storm system evolves.

Rest of today – quite warm, with high temperatures well in the upper 50s under mostly cloudy skies. Periods of light rain look to persist as a cold front makes its way across the area this evening, though it appears most of the precipitation should end by 7PM this evening.

Tuesday – with the cold front passing through tonight, temperatures will moderate tomorrow, dropping into the upper 40s under mostly clear skies.

Wednesday – a complex and potent storm system that will be impacting the Midwest the next couple days will make its way into the region Wednesday. A warm front will pass over our area prior to the passage of a cold front. As we enter the warm sector between these two frontal boundaries, we’ll see a surge of warm air and moisture from the south. This may even lead to a couple isolated rumbles of thunder during the afternoon. Otherwise, expect mostly cloudy skies with showers throughout the afternoon into the evening hours. High temperatures will be quite warm, again approaching 60ºF – and possibly surpassing this mark.

Thursday – just like tomorrow, once the cold front above pushes through the area, temperatures will again cool off back into the upper 40s (which is still about 10ºF above normal), and skies will clear.

NYC Weekend Weather – Jan 8, 2016

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.

NYC Weather Update – Dec 28, 2015

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.

NYC Weekend Weather – Dec 18, 2015

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.

NYC Weather Update – Dec 7, 2015

A rather uneventful beginning to the work week in terms of weather will be followed by a gradual warmup towards the end of the week. Temperatures the past couple of months have been very much above normal, and in some cases approaching the warmest months on record – this trend looks set to continue at least through to early next week and possibly longer.

Rest of today – surprisingly, there is an Air Quality Alert in effect this afternoon through midnight. Some lingering haze has been a smudge on what will otherwise be a sunny day with high temperatures in the mid-50s.

Tuesday – more clouds than sun to start the day, but then clouds diminish as an offshore low exits to our east. This offshore low is not expected to bring any precipitation to the area since it will be passing too far to the south of us. Temperatures will actually be a little cooler than today – in the mid-upper 40s – since winds circulating counterclockwise around this low will be coming from the north.

Wednesday – as the low above exits, a high pressure center will begin to take hold. Return flow from the south around the western edge of this high pressure and a passing warm front will again bring in milder air. High temperatures are expected to be similar to today in the mid-50s, with mostly sunny skies.

Thursday – the warmup continues with temperatures expected to be a couple degrees warmer than on Wednesday, and with ample sunshine.

NYC Weather Update – Nov 30, 2015

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 5, 2015

The warm trend we’ve enjoyed this week comes to an abrupt halt over the weekend as we return to seasonable highs in the upper-50s. We are due to enjoy a couple more days of much above average warmth beforehand, as we’re now in the warm sector south of a warm front that has pushed through and west of a cold front due in late Friday and into the overnight hours Saturday.

Rest of today – mostly cloudy with a high in the upper-60s. A slight chance of rain especially later in the afternoon.

Friday – we’ll be firmly within the warm sector tomorrow with a steady southwesterly flow. Warm air will work its way into the area and yield near record-breaking temperatures in the mid-70s, and possibly even warmer if there are any breaks for sun. There will be another chance at rain tomorrow afternoon and evening as the cold front nears and passes through.  noaad2

Saturday – a marked change in sensible weather is on tap for Saturday once the cold front passes through the region. Skies should clear from west to east over the day, but high temperatures will only be in the low-60s.

Sunday – even cooler, with highs only in the mid-50s under sunny skies.

NYC Weather Update – Oct 26, 2015

The weather story this week will feature a storm system that will be drawing on the remnant moisture from Hurricane Patricia and producing some heavy rain on Wednesday as it passes through the region. Aside from a wet day Wednesday, the remainder of the week looks to be dry with decently warm temperatures.

Rest of today – clear with high temperatures near 60.

Tuesday – mostly sunny with clouds increasing later in the day. High temperatures again near 60.

Wednesday – a low pressure center is expected to form over the Great Lakes region and strengthen Wednesday. A warm front attached to this low pressure center will pass through the region late Wednesday. Increasing chance for more widespread rain as the day progresses with a high temperature in the mid-60s. Some urban flooding could occur. Most of the heaviest rain will likely be falling in the late evening and overnight hours.gfs_namer_054_1000_850_thick

Thursday – could see a few showers in the morning, but then skies should begin to clear and allow for temperatures to warm up into the mid-60s again before a cold front drops through.

 

Drought Update

We’re hoping for the rains Wednesday to make a dent in the stubborn moderate drought that continues to cling to the metro area, in particular Long Island.
