Cold Front
A cold front will move through the area overnight tonight accompanied by several rounds of rain starting during the daytime hours today.
There are a few small spits of rain in the region already this morning, but anything that falls early on will be brief and light.
Rain showers will begin to increase during the late morning and midday hours, becoming widespread at times this afternoon. A few embedded thunderstorms will also be possible, leading to some brief downpours.
The rain will continue into the evening and overnight, with additional periods of widespread moderate rainfall with embedded thundery downpours.
South winds ahead of the front will keep temperatures warm today, though the clouds and rain will knock about 10 degrees off of yesterday’s highs. Low and mid 70s will be widespread.
Temperatures will stay in the 60s this evening but will drop to the upper 40s and low 50s overnight as the cold front passes through.
Rain will continue into the predawn hours before moving out. A few lingering showers will be possible during the first half of Wednesday morning.
In all, most areas should see at least a half inch of rainfall. Many areas may see closer to an inch, and isolated pockets could see over an inch and a half or even around two inches.
Northwest winds will increase behind the front Wednesday morning, peaking during the afternoon with speeds around 15 mph and a few gusts reaching 30 mph.
Sunshine will poke in and out of clouds with much cooler temperatures topping out in the upper 50s and low 60s.
Wednesday night will be cold with lows dropping into the mid and upper 30s. A persistent north wind may prevent frost from forming in open areas, but it would be wise to protect sensitive plants you aren’t ready to let go anyway.
Another Dry Stretch
Another large, dominating high pressure system will build in for the second half of the week and persist through the weekend.
The center of this high will be just to our west over the Upper Great Lakes on Thursday. North winds around 10 mph will push the core of cold air ahead of the high into the area.
Despite sunny skies, temperatures will struggle to make it to the mid 50s. Some reliable weather models have it even cooler. This is about 30 degrees colder than it was yesterday and Sunday.
The high will pass overhead Thursday night, leading to clear skies and calm winds. Widespread frost and freeze conditions are likely with temperatures ranging through the low and mid 30s. Isolated pockets will likely dip into the upper 20s.
This will likely end the growing season for many areas, meaning the National Weather Service will not be issuing additional frost and freeze alerts for at least some counties beyond Thursday night.
By midday Friday, the high will be centered near New York City. South winds on the backside of the high will set up with light speeds around 5 mph. This should be enough to get most areas back into the low 60s Friday afternoon.
More 30s are expected Friday night, though it should be the warmest of these three potentially frosty nights.
Saturday will be sunny with highs reaching the mid 60s. Some clouds may work in on Sunday from a coastal system, but the high pressure should block most of them from making it too far northward. Highs will stick to the mid 60s.
Monday will also have sun and clouds with highs in the mid 60s.
Confidence in the weather forecast goes down beyond that with mixed models. Some keep the area dry until the weekend, while others start to show some rain during the mid and late week periods.
Temperatures generally look as though they will stay in the 60s, but it may turn cooler by next weekend.
