NYC Weather Update – Jan 30, 2017

NYC, Snow, Weather Update, , , , , , , ,

As we open February, temperatures will be appropriately cold and seasonable for this time of year. We have a chance for some light snow accumulation Tuesday with a passing clipper system. Looking into the long-term, some forecast models are indicating the possibility of a couple coastal storms that could be snowmakers next week.

Rest of today – mostly sunny with high temperatures peaking in the mid-30. Steady northwest wind around 15mph will produce wind chills below freezing.

Tuesday – high again in the mid-30s, but with snow expected in particular in the afternoon hours with an advancing clipper system and cold front. Snow accumulations are not expected to exceed 1 inch at this time.

Wednesday – brief rebound in temperatures into the mid-40s, with skies beginning to clear during the day.

Thursday – temperatures drop back to seasonable levels in the mid-30s.

 

More Significant Snows Ahead?

Looking ahead at Monday after the Superbowl, there appears to be a chance for a more significant snowmaker in the form of a coastal low. The forecast on this will become more clear as the week draws to a close.

NYC Weekend Weather – Mar 3, 2016

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

As we approach spring, the weather has a tendency to swing wildly between different extremes. We start this forecast period off with accumulating snow, while by this time next week, we are expecting temperatures in the 60s!

Rest of today – mostly sunny, but cool with below average high temperatures in the upper-30s.

Friday – overnight tonight into the first half of Friday, our area will get impacted by the northern fringe of what is expected to be a powerful coastal storm. Lucky for us, high pressure north of us is sufficiently strong so as to prevent this storm from hitting us dead one, which would certainly result in a more significant snowfall event. In this case, we are expecting to see snow in the range of 1-2″ across the city and Long Island with lesser amounts further north and west. Temperatures will remain colder than nom

Saturday – high pressure takes control with skies clearing and temperatures in the low-40s. Another slight chance for snow Saturday night accompanies the passage of a clipper system.

Sunday – partly sunny with highs around average in the low-mid 40s.

Monday – temperatures start to warm up as the high pressure moves offshore to the east and warm, southwesterly return flow circles clockwise around its western periphery. High temperatures in the low-50s.

Warming Trend Ahead

With the aforementioned high pressure center offshore in the Atlantic early to mid-week next week, we’ll see increasingly warm temperatures, up into the 60s by Wednesday. This warm trend looks to continue over the course of the next week, with a brief cooldown late next week before what should be a warm weekend next week.

NYC Weather Update – Jan 18, 2016

Noreaster, NYC, Snow, Storms, Weather Update, , , , , , , , ,

Weather to start this week will be rather uneventful, predominantly featuring windy, cold days, but little in the way of precipitation. We did get our first dusting of snow so far this winter in the city last night, and the potential for significantly more exists with a possible Nor’easter coming this weekend. As always, even though we’re within a week of this event, our local forecast office is only forecasting with 30% confidence due to the large changes in impact that even small fluctuations in storm track and intensity could bring.

Rest of today – we’ve already hit high temperatures for the day around 30ºF. A tight pressure gradient is causing breezy west winds near 20mph translating to wind chill values in the 10-15ºF range.

Tuesday – basically a repeat of today, but with slightly stronger winds. High temperatures will be in the upper-20s to around 30ºF with west winds in the 20-25mph leading to wind chills in the single digits to low teens under mostly sunny skies.

Wednesday – warmer, with high temperatures closer to normal in the mid-30s, calmer winds and sunny skies. There could be some flurries Wednesday night with a passing clipper system, but no accumulation is expected in the city.

Thursday – mostly sunny again with high temperatures in the mid-30s.

 

Possible Nor’easter This Friday – Saturday

Looking ahead towards the end of the week, there is a possibility for the first significant snowfall event in the NYC region thus far this winter. Forecasters are keeping close tabs on the possible formation of a classic Nor’easter towards the end of this week. It is important to stress that even at this point in time, there’s still considerable uncertainty about how this scenario will unfold. A deviation in the track of this coastal low too far north would result in a mainly rain event along the coast, while a deviation too far south would mean significantly less precipitation. If this scenario plays out under optimal conditions, our region would be in the northwest quadrant of this low, an area that favors the development of heavy snow. Even then, as was the case a couple winters ago, slight changes to the track and position of the heaviest snow bands could mean the difference between 5″ of snow or over a foot. Stay tuned for updates.

NYC Weather Update – Jan 11, 2016

NYC, Rain, Snow, Weather Update, Weekend, , , , , , ,

This week will feature below normal temperatures for the most part, with a chance at some snow showers for the first time this winter coming along with an Alberta clipper type system tomorrow afternoon into the overnight hours. Later on this week into the weekend, we are looking at a more potent and complex storm system that could bring a mix of precipitation to the area.

Rest of today – mostly sunny with scattered clouds and a high temperature in the mid-30s. A breezy day with west winds in the 15-20mph range.

Tuesday – partly sunny to start the day, with high temperatures hitting the upper-30s to about 40ºF. Snow flurries/rain could mix together in the afternoon. As temperatures drop after sunset, precipitation should transition to all snow. Due to the quick moving nature of this clipper system, we’re not really expecting any accumulating snow.

Wednesday – following the passage of the clipper system, winds pick up again from the west in the 15-20mph range, delivering a cold day with partly sunny skies and high temperatures right about freezing.

Thursday – slightly warmer, with high temperatures in the mid-30s, and a calmer wind so not as much of a biting cold.

NYC Weather Update – Jan 20, 2015

NYC gets brushed by a fast-moving Alberta Clipper system, with the potential for some light accumulating snow across the area Wednesday afternoon and evening. High pressure builds behind the clipper system Thursday and Friday, with high temperatures about average for this time of year. There’s some potential for a coastal storm approaching on Saturday/Saturday night, but with considerable uncertainty at this time, it remains to be seen if this scenario pans out, and if it results in snow or rain or a mix of wintry precipitation.

Wednesday – clouds increasing through the day with high temperatures in the mid-30s. Flurries may develop in the afternoon, however, the bulk of any snow is more likely to occur later in the evening and overnight. Max accumulations of 2″ in the city (1″ is more likely).

Thursday – mostly cloudy day with some snow flurries possibly lingering into the morning. High temperatures around the mid-30s.

Friday – high pressure continues to build over the region with skies clearing and high temperatures again in the mid-30s.

Saturday – forecast models are hinting at a coastal storm for Saturday. Right now, it appears as though the storm track brings the center of the low slightly to the east of the 40ºN 70ºW benchmark. Temperature profiles in the area also appear to be around the freezing mark. This will bear monitoring, as a slight westward jog of the storm track and a cooler temperature profile could result in some significant snow.
