Mainly VFR conditions are expected through 18Z. Scattered 
showers with embedded thunderstorms are expected to develop 
after 18Z, with the best chance from 21-00Z. Kept TSRA chances 
in a PROB30 at this time as confidence in the coverage of TSRA 
remains uncertain. If a thunderstorm does occur, it could be 
strong to severe with brief strong gusty winds up to possibly 40
to 50 kt. MVFR or lower conditions possible in any TSRA.

Aft the fropa, CIGS lower to around 4000ft overnight with the 
potential for additional shwrs. Confidence in shwrs is low so 
they have not been included in the TAFs. 

WSW winds this mrng, becoming NW this afternoon and evening aft
the fropa. The flow veers further to the NE aft 8-9Z Thu. Wind 
speeds generally around 10-15 kt much of the TAF period with 
gusts to near 20 kt this afternoon.
