11/12 – Rob Knight’s “Sunny & Cool” Friday Morning Forecast
A large upper level low-pressure will continue to spin over the western Great Lakes through Saturday. Another upper-level disturbance to the NW will move through tonight with a reinforcing shot of cooler/drier air mass through the region. Upper level high-pressure over the southeastern states will move off the Atlantic seaboard. Today will remain mild and dry through the daytime hours out ahead of the stronger secondary cold front. This will bring a dry cold front through Friday evening with increasing north winds and temperatures falling into the 50s by 9 PM pretty much area wide. This secondary front will continue to filter in Friday night with temperatures dropping into the lower 40s to the lower 50s. Winds will increase as well with surface high building in Friday night and Saturday.
A weaker disturbance will dig through the lower Great Lakes and Ohio Valley on Sunday. This will bring no impact to the local region as surface high remains overhead. However…min temps for Monday morning will be the main impact for drainage areas. This is due to cold air drainage behind the trough over the east TN valley and northern AL region. Temperatures will rebound back to near normal on Monday as high pressure moves off to our east with zonal flow remaining in place to our north. This will keep weather dry with temperatures rebounding to above normal status by mid-week with high temperatures possible reaching the middle and upper 70s.
Small Craft Advisory: 9 pm Friday – 9 pm Saturday
