NYC Weather Update – Apr 1, 2014

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

Don’t be fooled by this gorgeous weather today (seriously).

A low pressure system forming in the lee of the Rockies, along with a nearly stationary frontal boundary draping down from a low moving into Canada will result in cloudy to mostly cloudy skies for the remainder of the week. There will be a chance for rain each day through Friday. The best chance for steadier rain will be late in the day Friday through Friday night and perhaps into early Saturday morning. This is associated with another area of surface low pressure and trailing cold front.

Note the frontal boundary draping across the region - this will give us a chance for showers each day Wednesday-Friday.

High temperatures will warm to near 60 Wednesday with a persistent south-southwesterly flow ahead of the aforementioned frontal boundary.

Thursday – with the influence of clouds and possible showery rain, temperatures will most likely hover around the mid 50s.

Friday – rain increasingly likely throughout the day Friday with high temperatures continuing to drop to around 50.

Saturday – temperatures will warm again into the upper 50s ahead of a cold front (and with a warm front forecast to swing through), however, it will be a cloudy day with a diminishing chance of showers through the day.

Sunday – the cold front will have passed through allowing for skies to clear, but temperatures will be cooler in the low 50s with winds from the northwest.

 

Next shot at precipitation comes Monday night into Tuesday with a surface low tracking from the Southeastern US.

If you’re getting ready to venture out this evening make sure to bring an umbrella and wear your rain gear as a heavy rain event is in store for the New York City area. This will be an extended rainfall event leading into Monday. temperatures today will peak at around 50, near normal. The heaviest rain will be falling from approximately 8 p.m. tonight into the overnight hours. Winds will be at around 25-35 mph. Parts of the area are forecast to receive between 1.5″-3″ of rain in the next 48 hours, which could lead to some minor flooding in poor drainage urban areas and small creeks.

So, in general expect conditions to gradually deteriorate through the day and the intensity of rain to pick up. Rain will continue on Sunday, albeit with diminished intensity. Temperatures will hold steady around 50.

Refer to the diagram below, which represents the North American models guidance for this evening at around 8 p.m. Note the areas of blue and bright blue that correspond to rainfall rates anywhere between .75″ to 1.5″ per hour.

High pressure will move in Tuesday, with a weak cold front moving through later Tuesday. This frontal boundary is not forecast to produce any precipitation. Ahead of this frontal system, we’ll see temperatures rebound to seasonal levels in the mid-upper 50s and partly cloudy skies. Wednesday will likewise be a seasonable day with mild temps near 60.

Light rain is possible Thursday, Friday, and Saturday of next week, but it’s much to early to be certain. GFS model also shows a possible coastal storm for next Tuesday.
