...HEAT ADVISORY IN EFFECT UNTIL 7 PM EDT THIS EVENING...

.DISCUSSION...
Expansive high pressure remains in place with heat impacts
remaining the main concern. Scattered showers and isolated
storms may occur at times mostly late morning into mid afternoon
before precipitation activity moves inland with the southwest
flow in place today by the evening hours. With decent mixing
heights reaching around 4000-4500 ft later today, dispersion
conditions are generally expected to be fair to good with
minimum RH values dropping to to near or just below
60 percent this afternoon.

Southwest flow continues into Friday with mixing heights possibly
reaching somewhat higher than today so this should yield
more favorable dispersion conditions.
