.DISCUSSION...

High pressure centered over Bermuda will maintain southwesterly
winds, and a more humid airmass over the region through Saturday. 
This pattern will lead to much warmer temperatures areawide that 
will run nearly 15-20 degrees above normal on the daytime and 
nighttime temperatures. Dewpoints will generally remain in the 
50s to 60s across the area through this time period, leading to 
minimum RH values in the 40-50% range through Saturday before 
much drier air filters into the region behind the passage of 
a cold front Saturday night into Sunday. This cooler and drier
airmass will return temperatures to near normal for this time 
of the year; however, RH values look to bottom out in the 20-30%
range each day next week starting on Monday. Gusty winds on Monday
and Tuesday up to 20mph next week may lead to some increased 
fire weather concerns; however, as they become more relaxed by 
Wednesday and Thursday, conditions look to be more favorable 
for burning.
