.UPDATE...
For 12Z Aviation.

.SHORT TERM...
Today and tonight.

So the front we have been waiting for what seems like years for to
pass through has finally done just that. Analysis at 6Z has the
front well to the south of the area and the dewpoints are in the
50s at all locations with the exception of TOI and EUF. Those
sites will be falling soon. Meanwhile a second front will drop
toward the area before sliding east and washing out during the day
as high pressure builds into the area. Highs will be in the mid
80s today once again but with much drier dewpoints it will not
feel as muggy as it has for the past 2 weeks. Another fairly cool
night night with readings in the 50s to near 60 degrees along with
dry weather weather.

.LONG TERM...
Tuesday through Sunday.

Dry conditions should continue into Tuesday as a trough swings
through the Southern Appalachians. Moisture recovery will be
minimal in advance of this system with PWAT values well below
normal for late June. Northwesterly flow aloft will be replaced by
zonal flow on Wednesday as surface high pressure moves off the
East Coast. This will allow southerly flow to return to the
region. Also, a tropical disturbance in the western Gulf of Mexico
is expected to move northward toward the forecast area. Rain
chances should increase accordingly for Thursday as PWATs surge
into the 1.5 to 2 inch range. Weak westerlies at 500 mb will
represent weak troughing through the rest of the forecast period.
When combined with abundant moisture, this should result in 40-60
POPs focused in the afternoon and early evening hours.
