NYC Weekend Weather – Jan 5, 2018

Climate, NYC, Snow, Weather Update, Weekend, , , , , , ,

Record-breaking cold to impact the region on the heels of the snowstorm that hit yesterday. Brutally cold weather lasts through the weekend before a thaw in temperatures pushes us back into normal ranges to start next week. Temperature trends likely to continue to above normal levels finally after a long cold spell. Snowfall totals in the city from yesterday generally ranged between 9-12″.

Rest of today – clear, windy, with a high in the mid-teens. Stiff west winds in the 20 mph range will make wind chills feel like -10ºF to -15ºF. A wind chill advisory is in effect for this reason.

Saturday – overnight lows in the single digits. Wind continues to be a factor blowing at 15-20 mph with record low day time temperatures likely to be broken. Highs only in the mid-teens again despite clear skies.

Sunday – with winds abating late Saturday and clear skies, excellent conditions for strong radiational cooling will exist. Overnight lows into Sunday maybe only as high as 5ºF. Clear and sunny with a high near 20ºF.

Monday – an approaching low from the west finally helps push temperatures back up in the upper-30s. Increasing clouds. Light snow and sleet possible overnight into Tuesday.

 

Warming Trend to Continue Next Week

We finally get a break from the brutal cold as the jet stream flattens out over the Eastern US next week, pushing this bitterly cold Arctic airmass north. Climate Prediction Center calls for 33% chances of above normal temperatures over the next 6-10 days. Normal highs are in the upper-30s. The 40s will feel downright balmy compared the the 20ºF below normal temperatures we’ve been seeing.

 

NYC Weekend Weather – Apr 1, 2016

It’s going to feel like a bad April Fool’s joke hit us this weekend when the weather turns to a locked in pattern of below average temperatures – cold enough at times to support snow, perhaps even enough to accumulate. Hard to believe that we almost hit 80ºF in February.

Rest of today – a potent storm system that pummeled large parts of the south with severe weather, including tornadoes, will be moving through the area this afternoon. We won’t see anything nearly as powerful as the storms that hit the south, but it does look like there will be two rounds of moderate rain with a few thunderstorms. The first batch looks to hit around noon and lunch hours, while the second arrives later this evening around 7PM. Gusty southwest winds up to 30mph ahead of the passage of the cold front responsible for these storms will bring temperatures well into the upper-60s and low-70s.Screen Shot 2016-04-01 at 9.49.35 AM Screen Shot 2016-04-01 at 9.49.53 AM

Saturday – much cooler with temperatures in the upper-50s to around 60ºF. A chance for scattered showers remains due to the approach of another cold front from the Great Lakes.

Sunday – we’ll begin to feel the chill in earnest on Sunday as temperatures drop into the mid-30s overnight from Saturday into Sunday. A polar vortex will be moving in over a large part of the northern United States. There could even be some snow showers in the city on Sunday morning before skies clear and winds pick up from the northwest into the 20-30mph range with clearing skies. High temperatures will only be in the mid-40s, nearly 10ºF below average.

Monday – a warm front preceding a low pressure system will move through Monday allowing for temperatures to rise into the low-50s, however, this will be accompanied by rain. Overnight into Tuesday, temperatures should cool enough for this rain to transition to all snow for a period.

A Cool April

The polar jet stream will be dipping well south of us during the medium term, allowing for a polar vortex to move over the region. This will lead to a cooler than average first half of the month, and possibly the entire month. Today might be the last day we see the 60s and 70s for quite some time, so go out and enjoy it while you can.
