May 6, 2012: Storms Possible Monday Night

Forecast Highlights:

– Mostly cloudy skies return Monday; highs still in 60s
– Occasional showers and storms for Tues-Thurs; Up to 2 inches
– Seasonable temperatures continue this week, next weekend perhaps


After yesterday’s forecast bust, with more cloud cover and lower temperatures than expected, today ended up with partly/mostly cloudy skies, with high temperatures reaching the upper 60s inland, mid to upper 60s in the immediate NYC area, and the lower to mid 60s in Long Island and southern CT. Mostly cloudy skies are expected to return again later on Monday as the next low pressure approaches, with rain and thunderstorms returning for the mid week.

Week Overview:

Partly to mostly cloudy skies are expected on Monday with highs in the mid to upper 60s across most of the area. By Monday night, as the low pressure approaches, scattered thunderstorms are possible especially towards early Tuesday morning. Scattered showers and thunderstorms are possible during the day on Tuesday with temperatures slowly rising, peaking late in the mid to upper 60s from NYC and further west and the upper 50s to mid 60s elsewhere. Breezy conditions are also possible.

As a coastal low pressure begins to develop to the south, occasional showers and thunderstorms, locally heavy, are expected to continue on Tuesday night and Wednesday, with Wednesday bringing warmer temperatures, into the lower 70s west of NYC. Depending on the exact location of the low pressure, additional rain is possible on Wednesday night into Thursday, with cooler temperatures on Thursday dropping back into the 60s. Some clouds will stick around through Friday and the weekend with high temperatures generally staying in the mid to upper 60s, possibly a little higher. Uncertainty increases by next weekend, although no widespread rain event is expected, with rising temperatures and the possibility of a brief surge of moderate warmth towards early next week; under this current pattern, as mentioned in the May outlook, most warm spells will tend to be short lived, and should there be a warm spell by this time period, it is unlikely to end up as a long lasting one.
