ISOLATED CG LIGHTNING STRIKES HAVE BEEN OCCURRING ON THE OLYMPIC
PENINSULA OVER THE PAST COUPLE OF HOURS. THIS ACTIVITY IS PROBABLY
ASSOCIATED WITH INTENSE OROGRAPHIC FORCING AND WEAK DESTABILIZATION
IN MOIST ONSHORE FLOW REGIME. SLIGHT RIDGING/WARMING ALOFT IS
FORECAST ACROSS THE REGION THE REMAINDER OF TONIGHT AND THIS SHOULD
GENERALLY LIMIT TSTMS DESPITE A CONTINUATION OF MOIST ONSHORE FLOW.

WEAK WARM AIR ADVECTION/ISENTROPIC LIFT WILL PERSIST ACROSS RESIDUAL
FRONTAL ZONE OVER NRN FL. EVENING SOUNDINGS EXHIBIT A MOIST AIR MASS
SOUTH OF THE FRONT OVER CNTRL SECTIONS OF THE PENINSULA. A VARIETY
OF MODEL GUIDANCE SUGGESTS SOME POTENTIAL WILL EXIST FOR WIDELY
SCATTERED CONVECTION ACROSS THE REGION TONIGHT. HOWEVER...WEAK LAPSE
RATES AND LIMITED FORCING SHOULD KEEP ANY TSTM ACTIVITY QUITE
ISOLATED.
