Storm Updates: Short term graphics will be posted as well. Click on the image to see it in a larger size.


8:35 PM: The strong storms in east central PA are currently affecting the southern parts of the area with heavy rain and thunderstorms, focusing on southern areas of NYC and SW Long Island. These storms are not severe, as the severe storms are currently in the MD/DE/southern NJ area, though they are currently producing heavy rain and thunder. These storms will weaken as they move east towards Long Island over the next 1/2 hour.

This is the last storm update for tonight. The 5-Day Forecast page was updated, and the next full update will be posted tomorrow.

6:55 PM: An area of strong thunderstorms in east central PA is moving east, and will affect New York City approximately an hour from now. There are two heavy thunderstorms near Somerset county moving northeast, which will affect Union, Essex and Hudson counties over the next 1/2 hour with a brief yet heavy downpour.

The main area of storms is currently near Allentown, PA, and moving east. These storms will move into Hunterdon, Somerset, Middlesex, and potentially Union counties over the next 3/4 to 1 hour, and then potentially into southern area of NYC (Staten Island, Brooklyn). These storms are capable of producing heavy rainfall and gusty winds.

4:50 PM: A strong thunderstorm formed over northern Bergen County 1/4 hour ago, and is currently over southern Westchester. This storm is moving ENE, and will affect Stamford, CT, producing heavy rainfall and gusty winds. Another strong storm is forming in SW CT and is moving ESE. This storm is expected to move just south of Bridgeport, CT within the next 20-30 minutes.


Today’s Storms:

4 PM: After several hours of sunshine across the area, temperatures quickly warmed up, reaching the lower to mid 70s inland, upper 70s to lower 80s in the immediate NYC area, and even reached the 70s across most of Long Island before a south wind began developing. Mostly cloudy skies are currently covering most of the area as some rain and thunderstorms are currently moving into NW NJ. These storms will continue to move ENE, reaching Westchester county and SW CT.

Looking across the region, there is currently one severe thunderstorm in northwestern Virginia. CAPE is up to 1500-2000 and LI is up to -5 in the central Mid Atlantic. Storms are expected to form and intensify in that region within the next several hours, with the highest risk of severe weather in SE PA, southern/central New Jersey and northern MD/Delaware, where storms could produce heavy rain, gusty winds and small hail. The parameters are less supportive in NYC, and even though a strong thunderstorm may be possible this evening in the immediate NYC area, the best risk of severe weather exists south of the area.

Stay tuned for storm updates that will be posted this evening.

This Week: Warm, Humid, Stormy

As the cold front stalls just south of the area tomorrow, cloudy skies with occasional showers are expected along with cooler temperatures, cooling down into the 60s and potentially the lower 70s west of NYC. Warmer temperatures will return on Tuesday and Wednesday, reaching the lower 80s from NYC and further west on Tuesday. Both days are expected to bring partly to mostly cloudy skies with a potential for scattered thunderstorms in the evening and overnight hours.

For Thursday, there is some slight uncertainty, however the latest models are suggesting that the storm may move through quickly enough to prevent any severe weather risk. More information on Thursday will be posted this evening after the rest of the evening models come out.
