As a high pressure system builds across the Great Lakes and into the Northeast, some dry and chillier air will be spreading out across the area during the day and night. The temperature Thursday afternoon will be no higher than the 40s. And, while this is actually pretty close to typical levels for this time of year, it will feel like a shock to the system because of just how mild it has been recently.
The next fronts are located in the Plains and Upper Midwest Thursday morning and will be ushering some milder air and moisture into the Eastern Region Friday, Friday night and Saturday. And, while Thursday night will be quite chilly, any clear evening skies should become increasingly cloudy by Friday morning. Then, we’ll be on the lookout for a passing shower bit of rain or drizzle Friday afternoon along the leading edge of some even milder air that will be reaching the mid-Atlantic region on Saturday, when our temperatures should at least approach 60 degrees.
There’s going to be a cold front located well north and west of the area on Saturday morning, which will be pressing southeastward during the afternoon and evening hours.
And this boundary should eventually wind up well to our south by late Saturday night. We described Wednesday how the primary wind flow behind it by Sunday should be out of the east and northeast, which will make it a “chillier day” than Saturday (going 55 on Sunday, as opposed to the 61 we are carrying on Saturday).
There will once again be some moisture overrunning this front later on Sunday and Sunday night, which could cause some spotty rain to begin breaking out across the mid Atlantic states and the Northeast.
