NYC Weather Update – Nov 16, 2015

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

This week will feature a mixed bag of warm and cool temperatures, along with a bout of moderate-heavy rain and even a couple thunderstorms associated with a cold front passing through the region on Thursday into Friday. Timing of this frontal passage isn’t 100% certain at this point. However, it is clear that behind this front, temperatures will take a dive into more seasonable ranges in the upper-40s to around 50ºF by this weekend.

Rest of today – clear skies with a high temperature well into the mid-60s. This is due in part to high pressure to our south that’s allowing for warm air to flow in from the west.

Tuesday – quite a different story in terms of temperatures. A backdoor cold front pushes through overnight, leading to a shift in winds to the northeast by tomorrow. This wind pattern favors cooler temperatures as the winds circulating clockwise around a high pressure center over the Canadian Maritimes bring in a cooler airmass. High temperatures will struggle to hit 50ºF in this atmosphere.

Wednesday – temperatures quickly rebound as winds switch back to the south-southeast ahead of a cold front which will be passing through the area sometime late Thursday. Cloud should increase during the day, but enough sun should still get through to get temperatures back to near 60.

Thursday – a mostly cloudy day with periods of rain throughout looks to be the headline for Thursday. Temperatures should warm up nicely into the mid-60s with warm, moist air entering the area from the south ahead of the actual cold front. Periods of heavy rain at times could be accompanied by an occasional thunderstorm especially as the cold front nears.gfs_namer_075_1000_850_thick 2

 

 

 

NYC Weather Update – May 18, 2015

Rain, Thunderstorms, Weather Update, , , , , , ,

This week starts off with a backdoor front over us, bringing us much cooler temperatures than yesterday, as well as patchy dense fog. Tomorrow, the Canadian maritime airmass responsible for these conditions will be replaced by a warm, moist airmass originating from the Gulf. By mid-week, a passing cold front will usher in seasonable, and dry conditions to the region.

Rest of today – mostly cloudy, cool, with an easterly wind suppressing temperatures, which will top off in the mid-60s.

Tuesday – the backdoor front above will move back north overnight as a warm front. This will allow a transition to a southwesterly flow, which will bring warm, Gulf air into the area. High temperatures should be in the mid-70s amidst cloudy skies, punctuated by periods of rain as a cold front approaches from the west. There is some chance at a couple thunderstorms as well.

Wednesday – when the cold front moves through late Tuesday, it will set up cooler, but pleasant, dry, and sunny conditions on Wednesday. High temperatures around 70.

Thursday – the good weather continues with mostly sunny skies and high temperatures in the low-70s.

NYC Weather Update – Apr 27, 2015

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

After a few winter-like nights last week, things are back on the mend in terms of temperature this week. Wednesday should be the best day of the week, with mild temperatures in the upper-60s and sunny skies. Wednesday will be bookended by the rest of the week, which won’t be quite as pleasant. But, it won’t be as cold as it has been the last week.

Rest of Today – skies will be variably cloudy during the rest of the afternoon, with a chance for rain showers. This is due to the influence of a low pressure system in the Gulf of Maine that is inducing some instability here, as well as allowing a cool, moist, Canadian maritime airmass to enter the area.

Tuesday – slightly better conditions than today with that low pressure exiting over the Atlantic. Skies should be mostly sunny with high temperatures in the mid-60s.

Wednesday – highlight of the week, featuring sunny skies and mild temperatures near 70.

Thursday – clouds return and temperatures fall back into the lower 60s in response to an approaching low pressure system from the Carolinas.
