DISCUSSION

KEY MESSAGE 1...Temperatures will moderate late week through the end of the weekend with a few weak systems bringing chances of light precipitation, mainly rain, before a cool-down early next week.

No significant weather expected through Thursday. Below normal temperatures and dry with variable cloud cover.

A warm front will lift northward across the region for Thursday, pushing temps about 7-10 degrees warmer than we are expecting for Wednesday, closer to normal. Not expecting any precip with it. A weak cold front will then slip by to the north Thursday night, with just a chance of some spotty light rain and perhaps some higher elevation snow across areas well north and west of I-95. That system stalls and lifts back out on Friday, with temps nudging even a bit milder by about 5-8 degrees compared to Thursday. Another warm front passes Friday night with another shot of rain, again best chances being north and west of I-95, with temps again moderating a few more degrees right behind it for Saturday. A warmer push continues behind that system with another bump in temps for Sunday, likely reaching the middle to upper 60s for much of the region. A cold front then slips southeast bringing some showers across the region late Sunday into Sunday night with more seasonable temps returning Monday. Colder Canadian high pressure builds farther southeast into the region for Tuesday with below normal temps returning.
