...NO SVR TSTM AREAS FORECAST...

...NRN PACIFIC COAST...
ISOLATED THUNDERSTORMS HAVE BEEN OCCURRING OVER THE ADJACENT WATERS
AND IMMEDIATE COASTAL SECTIONS OF WA/ORE/EXTREME NRN CA THIS
AFTERNOON AS COLD UPPER TROUGH /500 MB TEMPERATURES NEAR -35C/ MOVES
INLAND.  00Z SOUNDING AT MFR INDICATES SUFFICIENT CAPE IN THE -10 TO
-20C LAYER TO PROMOTE CHARGE SEPARATION...AND SATELLITE IMAGERY
INDICATES CELLULAR CONVECTION CONTINUING OVER THE COASTAL WATERS
WITH OCCASIONAL CG LIGHTNING STRIKES DETECTED. POTENTIAL FOR
ISOLATED THUNDERSTORMS WILL GRADUALLY END FROM THE WEST DURING THE
03-06Z PERIOD AS THE UPPER TROUGH MOVES INLAND AND HEIGHTS BEGIN TO
RISE ALONG THE COAST.

...SRN GREAT BASIN INTO FOUR-CORNERS REGION...
A FEW THUNDERSTORMS HAVE DEVELOPED OVER PARTS OF SERN NV AND SWRN UT
WITHIN SATELLITE INDICATED MOISTURE PLUME AS DYNAMIC FORCING FOR
LARGE SCALE ASCENT INCREASES IN THE RIGHT ENTRANCE REGION OF UPPER
LEVEL JET STREAK MOVING ACROSS THE GREAT BASIN.  THE THREAT FOR
ISOLATED THUNDERSTORMS IS EXPECTED TO SPREAD EWD TOWARD THE
FOUR-CORNERS REGION TONIGHT AS THE JET STREAK PROGRESSES EWD TOWARD
THE ROCKIES.

...NRN PARTS OF MS AND AL/ERN AR AND WRN TN...
MODELS INDICATE SWLY LOW LEVEL JET WILL STRENGTHEN ACROSS THE LOWER
MS VALLEY TONIGHT AS SURFACE LOW NOW OVER SERN CO REDEVELOPS EWD
INTO SRN OK BY 12Z.  GPS WATER VAPOR DATA SHOW RETURN FLOW MOISTURE
IS INCREASING NWD ACROSS ERN TX AND WRN LA...AND ELEVATED MOISTURE
SOURCE IS LIKELY TO SPREAD NEWD ACROSS THE LOWER MS VALLEY LATER
TONIGHT.  SCATTERED ELEVATED CONVECTION IS EXPECTED TO DEVELOP AFTER
06-09Z ON THE NOSE OF THE LOW LEVEL JET WHERE CONVERGENCE AND WARM
ADVECTION LIFT WILL BE MAXIMIZED.  THERE IS A LOW PROBABILITY OF A
FEW LIGHTNING STRIKES DEVELOPING LATE TONIGHT BUT OVERALL COVERAGE
IS EXPECTED TO BE VERY LIMITED.
