VALID 261200Z - 011200Z
A SHORTWAVE TROUGH OVER THE SRN PORTION OF THE CANADIAN PRAIRIE
PROVINCES WILL TRACK SE INTO THE UPPER MIDWEST/GREAT LAKES
REGION...RESULTING IN A DEEPENING TROUGH OVER THE ERN STATES THROUGH
MONDAY/DAY 5. SEVERAL WEAKER IMPULSES WILL MAINTAIN THIS TROUGH
THROUGH THE END OF THE FORECAST PERIOD. SOME ENHANCED WLY FLOW WILL
BE POSSIBLE ON DAY 3/SAT ACROSS PARTS OF THE NRN PLAINS INTO THE
CNTRL ROCKIES AS THE AFOREMENTIONED SHORTWAVE TROUGH BEGINS TO TRACK
SEWD TOWARD THE UPPER MIDWEST. AS A RESULT...MARGINALLY DRY RH
VALUES FROM ERN MT AND THE WRN DAKOTAS...AND ACROSS PARTS OF SRN
WY...WILL ALIGN WITH BREEZY CONDITIONS ON DAY 3.
ACROSS THE WEST...HIGHLY AMPLIFIED UPPER RIDGE WILL BUILD OVER THE
INTERMOUNTAIN WEST INTO WESTERN CANADA DURING THE DAY 3-8 PERIOD.
THIS WILL RESULT IN AN EXTENDED PERIOD OF DRYING WITH HOT CONDITIONS
ACROSS MUCH OF THE WESTERN STATES. AS MODEST MIDLEVEL MOISTURE
MIGRATES NWD BENEATH THE RIDGE...THUNDERSTORMS ARE LIKELY ACROSS
PARTS OF THE PACIFIC NW INTO THE NRN ROCKIES...WITH DRY
THUNDERSTORMS POTENTIALLY A CONCERN DURING THE WEEKEND AND INTO
EARLY NEXT WEEK. WITH THE LACK OF ANY STRONGER FORCING MECHANISM
IMPINGING ON THE WESTERN STATES...DRY LIGHTNING THREAT EACH DAY
SHOULD REMAIN RATHER UNFOCUSED AND GENERALLY SPORADIC/ISOLATED. AS
SUCH...CONFIDENCE IS LOW BEYOND ABOUT DAY 4/SUN WHERE/IF GREATER DRY
THUNDERSTORM THREAT MAY ALIGN WITH FAVORABLE DRY FUEL CONDITIONS.
