May 9, 2013 Storm Updates

3:45 PM: Storms Moving Out

Widespread showers and thunderstorms affected Long Island and southern CT over the last few hours, with radar estimates showing most of the LI/CT region aside from central Long Island with up to 1/4″, locally higher. Since then, these showers have mostly moved out of the area, and are currently focused over central-northern CT. With the upper level low nearby, mostly cloudy skies are expected for the rest of the day with a risk of isolated showers but no widespread moderate-heavy rain. The next round of rain after today is expected on Saturday night into Sunday with an incoming cold front separate from the current ULL.

 

11:35 AM: Storms Continue

The batch of rain that was previously located over NE NJ has since moved north into SE NY, producing moderate to locally heavy rain. Radar estimates show a band of 1/2 to 1 inch of rain from Newark to western Bergen county in NJ and Rockland county in NY, with the highest total so far in Newark, NJ with 1.40″ of rain so far. A localized strong thunderstorm is located over Queens, producing locally heavy rain with radar estimates also showing a small area of near 1″ totals.

Additional thunderstorms are forming and expanding off the coast, tracking north into Long Island. A developing batch of moderate to heavy thunderstorms will move onshore into Nassau and western Suffolk counties shortly, producing at least 1/4″ to 1/2″ with locally higher amounts. Another strong thunderstorm is currently south of central Long Island and tracking NNE, which should affect the eastern half of Suffolk county within the next 30-60 minutes.

9:45 AM: More Rain Near NJ, NYC

As mentioned last night, an area of showers, locally heavy, developed near eastern NJ and is currently slowly moving NNE, affecting NYC and especially northeast NJ with moderate to heavy rain. The heaviest rain from this batch of rain is between the I-95 and Garden State Parkway corridors with a narrow strip of 1/2″ to 1 inch, while other locations have generally recorded up to 1/4 inch so far. This round of rain will continue for at least the next 1-2 hours, tracking north into SE NY while clipping western parts of LI and CT. At least 1/4″ to 1/2″, locally up to/slightly over 1″ in isolated spots, is expected across north central/NE NJ and SE NY, with NYC on the eastern end of this area.

Meanwhile, another batch of rain is located near eastern Long Island and SE CT, also tracking north. This area of rain is weaker than that near NJ, but is still producing light to moderate rain with amounts generally up to 1/4″, locally higher. A break in the rain is likely near NYC and NJ later today as the upper level low moves overhead, with scattered showers/storms to continue in LI/CT at least through the early afternoon hours.
