PM Update: Milder this week, more wintry by weekend
The trend towards milder temperatures continues this week, as high temperatures rose into the upper 40’s and the 50’s throughout the area on Tuesday. The modifying airmass and stagnant high pressure are initially to blame this week, with no reinforced source of cold arctic air. But by Wednesday into Thursday, the warm air will be forced northward by a surging warm front and associated storm system moving through the Great Lakes.
The warm front moving northward on Thursday will bring an unseasonably warm airmass with it. Southerly winds will pump in very mild air, with temperatures rising into the 60’s by Thursday afternoon. But the warmth will be short lived, as a cold front moving through the area on Friday will mark the beginning of another infiltration of arctic air.
