NWS STORM PREDICTION CENTER NORMAN OK
0310 PM CDT MON JUL 27 2015

VALID 291200Z - 041200Z

THE STRONG SHORTWAVE TROUGH WHICH IS CURRENTLY MOVING ACROSS THE NRN
PLAINS IS EXPECTED TO BE N OF THE INTERNATIONAL BORDER BY THE
BEGINNING OF THE EXTENDED PERIOD -- 12Z ON D3/WED -- WITH THE
OVERALL PATTERN THROUGH THE REMAINDER OF THE PERIOD DOMINATED BY
UPPER RIDGING. UPPER RIDGE INITIALLY CENTERED OVER THE SRN
PLAINS/LWR MS VALLEY WILL SHIFT WESTWARD WHILE EXPANDING. BY
D6/SAT...THIS UPPER RIDGE IS EXPECTED TO EXTEND FROM THE PACIFIC NW
SOUTHEASTWARD INTO THE LWR MS VALLEY. ANY STRONG FLOW ALOFT WILL
LIKELY REMAIN WELL N OF ANY AREAS WHERE WARM AND DRY SURFACE
CONDITIONS EXISTS...KEEPING THE WIND-DRIVEN FIRE WEATHER THREAT LOW.
MONSOONAL MOISTURE WILL MOVE THROUGH THE WRN PERIPHERY OF THE RIDGE
WITH TSTM ACTIVITY POSSIBLE ACROSS SRN CA AND AZ AS EARLY AS D3/WED.
TSTM THREAT WILL REACH NRN CA AND SRN OREGON BY D5/FRI. THESE STORMS
COULD BE MOSTLY DRY WITH AT LEAST SOME FIRE WEATHER THREAT DUE TO
DRY TSTMS LASTING THROUGH THE WEEKEND ACROSS NRN CA...SRN ORE...AND
SW ID. HOWEVER...UNCERTAINTY IS STILL TOO HIGH TO DELINEATE ANY
THREAT AREAS WITH THIS FORECAST.

...D3/WED: SW OREGON SOUTHWARD INTO THE NRN SACRAMENTO VALLEY...
OFFSHORE FLOW IS STILL EXPECTED EARLY D3/WED MORNING ACROSS THE WRN
FOOTHILLS OF THE SIERRA AND CASCADES AS WELL AS FARTHER W ACROSS THE
SISKIYOUS AND COASTAL RANGE. GUSTY WINDS COMBINED WITH POOR
OVERNIGHT RECOVERY AND DRY FUELS IS EXPECTED TO RESULT IN AN
ELEVATED FIRE WEATHER THREAT.
