DAY 2 CONVECTIVE OUTLOOK  
NWS STORM PREDICTION CENTER NORMAN OK
1225 AM CDT MON OCT 23 2006

VALID 241200Z - 251200Z

...NO SVR TSTM AREAS FORECAST...

...SWRN U.S...SRN PLAINS...

UPPER RIDGING WILL GRADUALLY BREAK DOWN OVER THE SRN PLAINS TUE AS
SEVERAL WEAK SHORTWAVE TROUGHS EJECT NEWD ACROSS NRN MEXICO INTO THE
SRN ROCKIES/TX REGION. THESE FEATURES WILL ENHANCE WARM ADVECTION
PROFILES DOWNSTREAM...WHILE ALLOWING MID LEVEL MOISTENING/WEAK
ELEVATED DESTABILIZATION WITHIN A PLUME THAT SHOULD STRETCH NEWD
ACROSS WEST TX INTO OK.  LATEST GUIDANCE SUGGESTS BOUNDARY LAYER
MODIFICATION ACROSS THE WRN GULF OF MEXICO WILL BE IMPEDED BY SFC
RIDGING...THUS FORECAST PROFILES ARE NOT PARTICULARLY UNSTABLE
INLAND.  EVEN SO...ISOLATED THUNDERSTORMS MAY EVOLVE WITHIN ELEVATED
CONVECTION ACROSS OUTLOOK AREA.

UPSTREAM...BOUNDARY LAYER DESTABILIZATION SHOULD BE MAXIMIZED NEAR
THE LOWER CO RIVER VALLEY BENEATH COOLING MID LEVEL TEMPERATURES OF
TROUGH AXIS.  ISOLATED THUNDERSTORMS SHOULD EVOLVE ACROSS SERN CA
INTO PORTIONS OF AZ DURING THE AFTERNOON HOURS.

...PACIFIC NW...

STRONG SHORTWAVE TROUGH WILL DIG SEWD INTO THE PACIFIC NW EARLY IN
THE PERIOD...WITH FOCUSED ASCENT EXPECTED WITHIN EXIT REGION OF JET
AXIS.  ISOLATED THUNDERSTORMS COULD EVOLVE WITHIN THIS ZONE FROM
SERN B.C. INTO THE ID PANHANDLE...AND PERHAPS WRN MT. 
ADDITIONALLY...STRONG COLD ADVECTION IN THE WAKE OF FRONTAL PASSAGE
SHOULD ENHANCE MARITIME BOUNDARY LAYER INSTABILITY ACROSS NWRN WA. 
A FEW THUNDERSTORMS SHOULD DEVELOP ACROSS THIS REGION THROUGH
00Z/25TH...THEN WARM ADVECTION WILL WEAKEN LAPSE RATES AND
CONVECTION SHOULD WANE.
