NYC Weather Update – May 10, 2016

Climate, Rain, Weather Update, , , , , , ,

What a difference a week makes in terms of the weather – we barely caught any sun last week, as we were dogged by several consecutive low pressure systems. This week, we’ve seen a shift in the jet stream and more high pressure in the picture, resulting in warmer temperatures and dry weather.

Rest of today – partly sunny with a small chance for showers later in the day and high temperatures in the mid-60s.

Wednesday – sunny, with high pressure in control, warm with temperatures in the low-mid 70s.

Thursday – another nice, sunny day, with high temperatures a shade cooler, in the low-70s.

Friday – the next chance for substantial precipitation comes along with a cold front arriving later in the day. Cloudy, with temperatures cooler in the mid-upper 60s.

Sunny but still below average

Temperatures will be much warmer than last week, but we’re still going to be missing the mark for average (around 70ºF) for the next few days. 610temp.new

NYC Weather Update – Mar 28, 2016

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

There will be a wet start and end to this week, with some fairly dramatic swings in temperatures in between as two storm systems affect the tangible weather across our region.

Rest of today – rain is tapering off across the region and there should be a slow clearing late in the day. High temperatures in the mid-50s.

Tuesday – the low pressure responsible for the wet weather today will strengthen as it departs to the northeast. The tightening pressure gradient will allow for stiff west winds to sweep across the area, in the 25-30mph range with gusts as high as 50mph. High temperatures will be about average in the low-50s with mostly sunny skies.

Wednesday – winds will diminish overnight Tuesday into Wednesday. With high pressure in place, this will set the stage for excellent radiational cooling that will allow for temperatures to plummet into the mid-30s and below freezing outside of the city. Temperatures should rebound back into the low-mid 50s during the day Wednesday.

Thursday – winds will switch to the southwest and temperatures will warm up into the mid-60s, despite increasing cloud cover. A chance of rain develops later in the afternoon with the approach of a cold front.

Friday – rain is likely for the first half of the day with temperatures about the same as Thursday in the mid-60s.

Easter weekend will be bookended by wet weather, but the weekend days themselves should be dry with temperatures around average for this time of year.

Rest of today – an earlier round of showers passed through earlier this morning. Another round of showers and scattered thunderstorms will pass through the region along with a cold front in the afternoon hours. It appears that there will be a good chance for rain between the hours of 12PM-6PM, after which skies should gradually clear.

Saturday – a cooler airmass will take over following the cold front today, so temperatures to start on Saturday will only be around 40ºF. Under mostly sunny skies, the high temperature should still hit normal levels in the low-50s.

Sunday (Easter) – clouds will be on increase for Easter, though no rain is expected. High temperatures will range in the mid-50s.

Monday – our next shot at rain arrives Monday with a warm front and a low pressure system moving up the eastern seaboard. Temperatures will be a bit warmer, in the upper-50s.

NYC Weather Update – Feb 29, 2016

Climate, NYC, Rain, Storms, Weather Update, , , , , , , , ,

This week opens up with some very mild and spring-like weather. March will arrive like a lamb for sure. However, following a storm system moving through Wednesday, temperatures will cool off to below normal levels, with a possibility for some snow Friday! This kind of highly variable weather is typical for spring, which officially starts in just under 3 weeks time.

Rest of today –  a line of showers associated with a cold front passed through this morning and has moved well off to the east of the city. Skies have cleared up, and temperatures are rising steadily into the upper-50s. Would not be surprised to see some areas top 60ºF this afternoon.

Tuesday – despite the passage of a cold front today, temperatures don’t cool off too much tomorrow. Mostly sunny skies should yield temperatures slightly above normal in the upper-40s.

Wednesday – the next storm system moves in overnight Tuesday into Wednesday. The low pressure center responsible for this storm is forecast to pass almost directly over the region early Wednesday morning. As it approaches, it will pull in warmer air from the south into its counterclockwise cyclonic flow, which will result in temperatures actually warming up overnight into the upper-40s. Temperatures will peak  Wednesday morning around 50ºF, accompanied by periods of rain. Rain should be dissipating by 2PM in the afternoon.

Thursday – following the passage of the low pressure above, temperatures will cool off into the upper-30s fro Thursday under mostly sunny skies.

Drought Ends

The last couple months have delivered sufficient snow and rain to bust the moderate drought that had been persisting over the NYC metro area, in particular on Long Island. This is excellent news for farmers and gardeners throughout the region ahead of the upcoming growing season.

NYC Weather Update – Feb 02, 2016

NYC, Rain, Storms, Weather Update, , , , , , , , , ,

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

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.

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 Weather Update – Dec 7, 2015

NYC, Weather Update, , , , ,

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

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.
