AVIATION...
Isolated shra/tsra will end shortly with generally clear skies
overnight. NAM soundings show some potential for a brief MVFR
cigs near KCLL between 12-15z Thursday. Also, some light ground
fog will be possible at KCXO and KLBX as temps cool to near the
dew pt under clear skies. Speed/directional convergence near the
coast could produce a few light showers near KGLS between 10-15z.
Moisture levels look less on Thursday and convective temps are
near 90 convective potential looks less than today and probably
confined to the late afternoon. Soundings support clearing skies
for tomorrow night. 43

MARINE...
Onshore flow can be expected each day with early morning showers
and thunderstorms becoming less during the daytime hours. High
pressure will weaken over the weekend which should allow surface
winds to increase as the pressure gradient tightens.
