May 5, 2011: Frost Inland Tonight

The next full update will be posted tomorrow, 5/6/11. The update will include an updated 5-Day Forecast as well.

------------------------------------------------------

A storm that moved through the region over the last two days, bringing severe weather to Pennsylvania on Tuesday and a cold rain to the NYC area on Wednesday as its cold front moved through, is currently affecting Maine with a cold rain. As this storm will exit the region tonight into tomorrow, it will also remove the cold air mass currently in place, which brought cold temperatures this morning reaching the lower 40s inland, however it is still expected to bring cold temperatures tonight along with mostly clear skies, reaching the upper 30s to lower 40s well north and west of NYC, lower to upper 40s in the suburbs of NYC, and the upper 40s to lower 50s in NYC.

Tomorrow will bring warmer temperatures, reaching the mid 60s to lower 70s across the area, though a developing weak low pressure off the coast will bring some light rain and potentially thunderstorms to the area on Friday night into Saturday morning. Mainly cloudy skies along with scattered showers are expected on Saturday, which will result in slightly colder temperatures, peaking in the lower to upper 60s across the area.

This storm is expected to intensify well offshore and stall in the western Atlantic early next week with a high pressure stuck over the area as well. Meanwhile, a storm developing over the central and western US will move east very slowly, staying over the same region from Monday to Thursday. As a result, weather conditions will be almost identical from Monday to Thursday, with partly sunny skies and high temperatures in the mid to upper 60s east of NYC and in the upper 60s to mid 70s from NYC and further west. There is some uncertainty with the exact timing, but the latest expectation is for the storm to finally reach the area by at least Friday. More information on this will be posted tomorrow.
