Forecast: Warmer but some rain expected this week

The unseasonably warm weather continues this week but it comes with a chance of showers for the next three days, forecasters aid.

Tuesday night turns cloudy with temperatures dipping to about freezing, the National Weather Service said.

Then Wednesday there is a 20% to 30% chance of showers after 4 p.m. and through the evening as temperatures rise overnight to the low 50s.

Thursday, the warmth is expected to keep coming with a high of almost 60 degrees, forecasters say, with steady breezes of about 15 mph. Lows should only by in the high 40s and there is a chance of rain Thursday night.

Friday is a mostly sunny day, the weather service said, but late at night there is an 80% chance of rain that results from at least three systems: a cold front that arrives and then stalls just south of the tristate area, a low pressure system in northern Quebec and a high pressure system out near Ohio and Western Pennsylvania.

the Midwest low pressure system, whose warm, rising air allows vapors to condense, plus a fourth system, a developing warm front, then combine to make rain likely.

Rains looks hard to avoid Saturday during the day; the chances ascend to 70%, but the warmth continues, with thermometers reaching 48 degrees during the day, the weather service predicted.

Look for "periodic showers to continue," it said, through late Saturday night and possibly into early Sunday morning.

Snow just might attempt to join in early Sunday before the daytime high goes to the low 40s and the sun comes out, forecasters said.

Sunday’s night’s low temperature will feel more winterish, sliding just below freezing to 29.

Sunday’s clear skies reflect another high pressure system arising in southern Canada.
