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.

A warm front will lift northward across the region tomorrow starting the trend of warmer conditions. Not expecting any precip with it. A weak cold front will then slip by to the north tomorrow night. Generally, the area looks dry but some flurries or drizzle are possible, particularly northwest of I-95. As warmer air continues to be ushered in, temperatures continue to trend warmer on Friday. Another warm front passes through the region Friday night, leading to some rain across the area. Behind the warm front, temperatures moderate a few more degrees 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.
