May 8: Windy, Cold, Then Stormy

For anyone who likes calm and dry weather, the next week is not going to be very pleasant. After this morning's storms, which produced rainfall amounts locally up to 1/2 inch of rain, windy conditions have already developed, and are expected to last through tomorrow night.

Winds tonight are expected to be in the range of 25 to 35 mph, with gusts as high as 50 to 55 mph. Some places near the coast and in Long Island may even see wind gusts up to 60 mph. This, combined with chilly temperatures in the 30s in the interior and lower to mid 40s for the New York City area, will make temperatures feel like the 30s tomorrow morning.

Tomorrow's Outlook:

Tomorrow is going to be much more different than today. Instead of mild temperatures, colder temperatures are expected, with high temperatures in the lower to mid 50s for the interior areas and in the mid to upper 50s for the immediate New York City area. Combined with windy conditions, it may feel colder, especially in the morning and evening hours.

Snow is going to make a brief return for the central and northern Northeast tomorrow. While our area should stay dry, the higher elevations of the Northeast should see wet snow with some accumulations, and even the lower elevations may see a little snow mixing in with the rain in the morning hours.

Cold Follows The Wind, Frost Expected

The wind should begin to calm down by Sunday night, however the temperatures are only going to get colder. With a cold air mass in place and mainly clear skies, low temperatures are going to drop into the lower 30s for the northwestern parts of the area, in the mid to upper 30s for the north and western suburbs of NYC, and in the lower 40s for New York City and closer to the coast. These temperatures, combined with a generally light wind, will result in wind chills in the 20s for the interior and in the lower to mid 30s for the immediate NYC area for Monday morning. Areas of frost are expected in the interor.

Monday should still be chilly, though temperatures are expected to be slightly warmer than Sunday, in the upper 50s inland and in the lower 60s for the immediate NYC area. Overnight temperatures should still be cold, similar to those of Sunday night, and as the wind should calm down by then, widespread frost is expected in the interior. Tuesday is going to be slightly warmer, with high temperatures in the upper 50s to lower 60s inland, and in the lower to mid 60s for the immediate NYC area.

Wet Pattern To Follow

After the cold temperatures to start next week, a wet pattern will affect the area from Tuesday night until next weekend. The first wave of rain is expected to approach the area on Tuesday night and last through Wednesday afternoon, bringing moderate to heavy rain and thunderstorms. At least 1/2 to 3/4 inch of rain is possible out of this first wave, with locally higher amounts possible. Due to the warm front staying to our south, there is going to be a sharp temperature gradient, with southern NJ in the mid to upper 70s while our area is in the lower to mid 60s.

An area of high pressure briefly moves in on Thursday, providing drier conditions and chilly temperatures, in the lower to mid 60s for the highs. By Thursday night or Friday, another wave of rain is expected to affect the area. There is uncertainty on this wave's timing and location, though in the wetter case scenario, another 1/2 inch of rain could fall between Thursday evening and Friday evening. There is uncertainty with the smaller details afterwards due to a large model spread, though it is likely that additional rain and thunderstorms will continue to affect the area through next weekend.
