NWS STORM PREDICTION CENTER NORMAN OK
0645 PM CST TUE MAR 04 2014

VALID 050100Z - 051200Z

...NO SVR TSTM AREAS FORECAST...

...OREGON COAST...

WARM ADVECTION IS EXPECTED TO INCREASE ALONG THE OREGON COAST LATER
TONIGHT AHEAD OF APPROACHING SHORT-WAVE TROUGH. MIDLEVEL
ASCENT/MOISTENING SHOULD CONTRIBUTE TO WEAK ELEVATED INSTABILITY
THAT MAY SUPPORT A FEW LIGHTNING STRIKES WITHIN DEEPER UPDRAFTS
ROOTED AROUND 800MB.

...ELSEWHERE...

STEEP LAPSE RATES...PARTLY DUE TO DIURNAL HEATING...HAVE CONTRIBUTED
TO ISOLATED THUNDERSTORM DEVELOPMENT FROM ERN ID...SWD INTO EXTREME
NWRN CO. THIS ACTIVITY IS EXPECTED TO DISSIPATE QUICKLY OVER THE
NEXT HOUR AS BOUNDARY LAYER COOLS.

...NRN GULF COAST...

WHILE WEAK ELEVATED INSTABILITY IS NOTED ALONG THE NRN GULF
COAST...THUNDERSTORMS ARE NOT EXPECTED TO SPREAD INLAND TONIGHT.
NRN EDGE OF LIGHTNING IS ROUGHLY 120 MI SOUTH OF THE LA COAST AND IT
APPEARS INSTABILITY SUPPORTIVE OF TSTMS SHOULD REMAIN WELL OFFSHORE.
