.DISCUSSION...
KEY MESSAGE 1...Dry through Friday, then rain associated with
Hurricane Isaias arrives over the weekend.

High pressure remains in control through Friday resulting in
clear skies and above normal temperatures.

Hurricane Isaias continues to strengthen in Gulf this morning,
now a Category 1 on the Saffir-Simpson scale. It is expected to
gain forward speed today and then make landfall along the Gulf
Coast sometimes late Friday. After landfall Isaias will quickly
weaken and become extra- tropical as it interacts with an upper
wave that is currently centered over southern Texas. The remnant
center will move north through the lower Mississippi Valley
region and ultimately through the Ohio Valley by Sunday.

Confidence continues to increase that a period of areawide rain
will fall beginning Saturday, continuing into Sunday. Overall,
rainfall appears to be beneficial given forecast amounts of 1 to
2 inches falling over a 48 hour period...therefore flooding
threat appears to be low at this time. However, favorable
southeast flow, given the current forecast track, may allow for
localized higher amounts along the eastern slopes of the Blue
Ridge due to upslope enhancement.

Wedging high pressure appears to be rather strong, so have
trended temperatures down several degrees on Sunday. Have also
trimmed out any mention of thunder given the stable airmass that
is expected to be in place.

.AVIATION /12Z THURSDAY THROUGH MONDAY/...
Clear skies today. VFR through the entire period with some high
clouds starting to head into NC/VA by 00z tonight.

Only issue this morning to be the usual valley fog. Front
moving in will bring winds up to 7 to 12kts from the northwest
through the afternoon.


EXTENDED AVIATION OUTLOOK...

High pressure will keep VFR conditions through Saturday morning.
The lone exception will be patchy river valley fog at BCB and
LWB during the early morning hours. Widespread rain arrives
Saturday afternoon and will continue into Sunday. Sub-VFR is
likely during this period at all terminals. Gusty southeast winds
will increase overnight Saturday and into Sunday. Some gusts to
30kts possible for BLF and LWB. Conditions will gradually
improve on Monday.
