.DISCUSSION...

High pressure will gradually strengthen across the region through

the weekend leading to a strong warming trend and continued dry

conditions. Temperatures will warm to above normal starting Friday

before peaking early next week. Expect little change in humidity

trends as MinRH values continue to range between 5-15% each day

and overnight recoveries stay between 20-35%. Winds will follow 

familiar diurnal trends with typical afternoon breeziness, gusting

mainly between 15-20 mph.



...Thunderstorms imply gusty winds...
