.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.
