NYC Weekend Weather – Feb 26, 2015

NYC, Snow, Storms, Weather Update, Weekend, , , , , , ,

Another cold weekend is on tap for the area, before the start of a week of active weather. It does appear that March will be coming in like a lion this year.

Rest of today – some sun, with a chance for light flurries and a high in the mid-20s.

Friday – diminishing clouds with a high temperature again in the mid-20s. High pressure begins building to our west, yielding northwesterly winds that will allow chilly, Arctic air to filter back into the area. Overnight lows Friday will be in the low teens.

Saturday – with high pressure to our west still firmly in control, it will be a sunny, but cold day, with highs again only in the mid-20s.

Sunday – clouds will be increasing ahead of an approaching storm system and as high pressure exits to the east. There will be a slight warmup ahead of the storm, with temperatures topping out near freezing. Snow likely overnight, although significant accumulations are not expected.

Monday – temperatures will warm potentially into the low 40s on Monday as warm air from the southwest gets pulled into the storm system. There may be some mixed precipitation along the coastal plain, with all snow elsewhere, mostly early in the day.9khwbg_conusTuesday – following the passage of the storm on Monday, temperatures dip back to around freezing, ahead of another storm system that will be impacting the area Tuesday into Wednesday. This storm has a greater potential significant precipitation.

After that brief “warmup” during the weekend, we’re once again mired in Arctic cold air. This cold trend continues with a reinforcing shot of cold air as a cold front sweeps through Wednesday. Behind that, high pressure builds in over the area for the end of the week and into the weekend, ensuring another prolonged stretch of chilly, much below normal temperatures.

Wednesday – ahead of what will a dry cold front passing through, high temperatures may be able to climb to just about the freezing mark under mostly sunny skies.

Thursday – once the cold front moves offshore, an area of low pressure will strengthen, but remain well offshore of the area. However, precipitation may still make its way over the region, especially the far eastern areas. There’ll be a chance for snow flurries further west in the city. Temperatures will be back in the mid-20s again in the wake of that cold front.gfs_namer_060_1000_850_thick

Friday – clearing skies will be accompanied by stagnant cold temperatures with highs again in the mid-20s.

Saturday – as you’ll se below, a strong 1040mb area of high pressure will be parked over the Ohio Valley will be responsible for the sunny, but cold temperatures through at least Saturday night. Highs Saturday may approach 30ºF. Normal highs for this time of the year are closer to 40ºF.gfs_namer_093_1000_850_thickLooking Ahead

Climate Prediction Center’s 8-14 day temperature outlook for March 4th to March 10th, with our region in an area expected to experience below normal temperatures.

The beginning of next week looks to feature a fairly active pattern, with two storm systems passing through, one on Monday, and another on Wednesday. With the current track of the second storm, it looks like we are going to be on the south side of the low pressure center. This would allow for warmer air to wrap into the area. We could top 40ºF again, but the tradeoff will be a slushy, wet day maybe with some mixed precipitation to start. Once this second storm passes through, we return to cold temperatures once again.

 

NYC Weather Update – Feb 8, 2015

Another messy start to the work week is in store for us tonight and into Monday night as we endure a long duration, though relatively light intensity winter storm. Luckily for us, the storm track means we’ll avoid the worst impacts of heavy snow (New England will get the worst of it again). There’s some concern for icing again, although the impact should be slightly less serious than last Monday. The rest of the week will be precipitation free, with the exception of some snow showers possible Thursday. Following these snow showers, another shot of brutally cold Arctic air is expected by week’s end, such that highs will only be in the low 20s and even upper teens.

Monday – as you can see from below, the snowfall totals for the southern portion of the NYC area are on the very low end, only 1-2″ expected in NYC and in Long Island. The higher snowfall totals will be north of I-84 and into Connecticut, with the far northern suburbs getting a chance at over 6″. Bear in mind, the snow is expected over an extended period starting tonight through Monday night.

Ice is a bigger concern for the immediate coastal areas that will see less snow. High temperatures during the day Monday be below freezing, so freezing rain is expected and could deposit between 0.15″-0.25″ of ice when all is said and done. The majority of this is expected to fall Monday morning before temperatures cool off at the coast and precipitation switches back to all snow.

Tuesday – high temperatures should be right around freezing with clouds diminishing through the day as the storm system from Monday pulls to the east.

Wednesday – a sunny day expected with highs again near freezing.

Thursday – we get our next chance at snow, on the light side, with a passing low pressure system forming over the Great Lakes and moving east towards us high temperatures will be again around freezing.

Friday –  a sunny, but frigid day with highs expected to only be in the upper teens and low 20s. As you can see from the chart above, to the west of the low affecting our area on Thursday, there is an area of high pressure which will usher in that reinforcing blast of Arctic air.
