NYC Weather Update – Sept 30, 2014

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

The skies look gloomy today, but there’s not a high chance of precipitation as the best dynamics for showers remain mostly offshore and to the east. High temperatures will be a bit above average with high temperatures in the low 70s.

Wednesday the chance for scattered showers will remain with a stationary frontal boundary slow to push south through our region. The best chance for precipitation will again lie to the east, likely well away from the city. High temperatures will be somewhat cooler around 70 with mostly cloudy skies.

Thursday – following the passage of the frontal boundary above, high pressure will build in from the north. Cloud cover should decrease gradually though not entirely clearing, but northeast and easterly wind will lead to cooler temperatures with highs only nudging the 70 degree mark.

Friday should be much the same as Thursday, with high temperatures right around 70 and clouds & sun.

Saturday – the forecast models are unambiguous in anticipating the passage of a negatively tilted cold front through the region (negative tilt in the northern hemisphere would correspond to a frontal boundary where the northern end lies to the west of southern end of the boundary, these types of fronts are often associated with higher levels of instability). Temperatures will be cool in the upper 60s to around 70, with a period of steady showers likely at some point during the day, right now it’s looking like this will be during the morning hours.

NYC Weather Update – Labor Day Weekend

Rejoice! The long awaited Labor Day Weekend is upon us. Although I’d love to say that the weather will be fantastic throughout, but unfortunately there will be a few disturbances traversing the region the second half of this weekend. Thunderstorms accompanying these disturbances may literally rain on the annual West Indian Day Parade in Brooklyn on Monday.

Friday – the remainder of today will be a picture perfect, fall-like day with high temperatures hovering right around 80. A pleasant, dry airmass is in place in association with an area of high pressure that’s currently sitting over us.

Saturday – essentially a repeat of Friday, but with a bit more cloud cover.

Sunday – high temperatures on Sunday will be considerably warmer than Saturday, since the area of high pressure sitting over us now will have moved to the east, building up southwesterly winds and allowing for an influx warm air to penetrate the region. Expect more humid and warm highs between the mid-upper 80s. A weak frontal boundary will be approaching Sunday, and transit the region late Sunday into Monday. This will be our first shot at rain and thunderstorms, some of which may deliver some heavy rain.

Labor Day – the timing of the aforementioned frontal passage will be critical in terms of sensible weather Monday. It currently looks like Monday will be partly cloudy, with highs again in the mid-80s. There will be an increasing chance of scattered thunderstorms later in the day Monday leading into Tuesday as another weakening cold front nears the area.

Tuesday – the return to the work week will continue to feature warm and humid highs in the mid-upper 80s and a continued chance of thunderstorms as that cold front works its way through.

NYC Weather Update – Jul 21, 2014

This will be my last weather update for the next 3 weeks as I will be traveling to Costa Rica during that time.

Tuesday – things will heat up on Tuesday as the high pressure center responsible for the what has been a refreshingly cool and fair stretch of weather moves to the southeast. This will allow warm, tropical air to move back into the area, setting the stage for high temperatures to climb well into the mid-upper 80s under partly cloudy skies.

Wednesday – the hot weather will intensify Wednesday as temperatures near or top 90 with a noticeable increase in humidity as well. Warm, humid air will be sandwiched between the Bermuda high and an approaching cold front. Scattered showers and thunderstorms are possible later in the day Wednesday. Inland areas to the west of NYC are most likely to see precipitation Wednesday.

Thursday – the aforementioned cold front will move further east, giving the city itself its best chance of a soaking rain on Thursday. Given the humidity and amount of water available for storms Thursday, flash flooding is possible within the heaviest downpours, otherwise mostly cloudy with temperatures in the mid 80s. I wouldn’t be surprised if a few strong to severe thunderstorms popped up Thursday.

Friday – the cold front will clear our area and exit to the east, while cooler air filters down from Canada. High temperatures will return to the low 80s with mostly clear skies.

The Weekend – looks like the weekend itself will be another nice one, with high temperatures in the low 80s both Saturday and Sunday. There is a chance of showers and thunderstorms Sunday leading into what appears to be a fairly active weather pattern for the beginning of next week.
