Subsidence from this high will provide clear skies overnight. based on this trend have adjusted hourly temperatures a little cooler. Temperatures will begin to moderate with highs on Tuesday in the low to mid 60s. Lows Tuesday night will range from the upper 30s in the east to the lower 40s across the west.
759 PM EDT Mon Oct 16 2017 After the warmest start to October on record at Tallahassee, a cold front is finally moving through the area and will usher in a noticeably cooler and drier airmass. Scattered showers and weak thunderstorms have developed along and ahead of the cold front that is draped across the region at this hour. With it's current pace, the front should clear the CWA no later than mid- evening, giving way to cloudy and much cooler conditions. Expect overnight lows to fall into the lower 50s across the northern half of the CWA under mostly clear skies, with low to mid 60s across the southern half, where cloud cover will remain prevalent overnight.

Current surface analysis reveals a broad 1032mb high pressure system in the Plains that extends well into the lower Ohio Valley. Temperatures tomorrow afternoon will be a few degrees warmer compared to today, as slightly warmer air advects in from the southwest around 850mb. Looks like the low levels of the atmosphere tomorrow will be capped and drier, so skies should be mostly sunny with only a few passing high clouds during the day. Expect another cool night tomorrow as temperatures drop into the lower 40s under good radiational cooling.
Still lingering cool temps aloft this aftn, but with ample sunshine temps have reached the low to mid 50s. Temps should be warmer than last night as warm front crossing the region keeps winds up just enough to prevent decoupling. Upper level troughing over the area early this week gives way to a more zonal flow pattern mid to late this week. Upper level trough slides across northern Ontario late Wed into Wed night. Low pressure tied to that troughing moves from western Canada Sat to scntrl Canada on Sat. Upper Great Lakes will be within low-level southwesterly flow ahead of the low. Conservative estimates would put high temps into the low 70s both days.
