Flooding Risks from Tropical Moisture Across the Southeast and Southwest

Tropical moisture from Isaias and Rachel will impact portions of the Southeast and Southwest this weekend. Flash flooding, strong winds and even a threat for severe thunderstorms and tornadoes are possible. Meanwhile, strong winds and dry fuels are raising fire weather concerns across the central Great Basin and western High Plains. Across the northern Rockies, first winter storm of the season.

.AVIATION /10Z SATURDAY THROUGH WEDNESDAY/...
Prevailing VFR remains likely through Today as a broad high 
pressure moves across the Northeastern US. Mid and high clouds 
increase through the day on today ahead of what is currently 
Hurricane Isaias. Winds will be out of the southeast at 5 to 10 
knots, though a few gusts to 20 knots will be possible at KJST 
during the afternoon. There is some guidance to suggest gust of 
35+ knots could occur at KJST after 04Z on Sunday, but 
confidence is low those winds mixing down to the surface. Any 
rainfall associated with the remnants of Isaias will hold off 
until late Saturday night/early Sunday morning. The initial 
thought on timing would be after 06Z Sunday is when 
precipitation would begin over the southwest. Rain and lowering
ceilings will then overspread across the region, with IFR
conditions likely for most TAF sites Sunday morning. 

Outlook...

Sun-Mon...Restrictions likely in lower ceilings and rain.

Tue...VFR favored, though a FROPA may bring restrictions in
-SHRA. AM fog possible.

Wed...AM ceiling restrictions possible from post-frontal 
stratocu, with VFR otherwise favored. Slight chance of -SHRA due
to lingering moisture behind front.
