SOUTHWEST AND NORTH CENTRAL MONTANA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE GREAT FALLS MT
1115 AM MDT MON JUL 7 2003
.DISCUSSION...
.TODAY...UPDATED THE ZONES AGAIN TO DROP TEMPERATURES. NOT EXPECTING
TO SEE MUCH SUN ACROSS MUCH OF THE FORECAST AREA TODAY...THE
EXCEPTION BEING PARTS OF THE SOUTHWEST. SEVERE THUNDERSTORMS STILL
LIKELY ACROSS OUR FAR EASTERN ZONES. BIGGEST CONCERN WILL BE
FERGUS COUNTY WHERE SOME HEATING IS OCCURRING DUE TO PARTLY CLOUDY
SKIES WITH DEW POINTS IN THE LOWER 50S. MEIER
TONIGHT THROUGH THURSDAY...SYSTEM MOVES EAST OF MY CWA BY EARLY
EVENING. AN UPPER LEVEL RIDGE BUILDS OVER THE WESTERN CONUS WITH
SURFACE HIGH PRESSURE OVER THE PACIFIC NORTHWEST PROVIDING CONTINUED
DOWNSLOPE WINDS THROUGH WEDNESDAY NIGHT. PERIOD WILL BE DRY AND WARM
WITH NO PRECIPITATION FORECAST. RELATIVE HUMIDITY VALUES DROP TO NEAR
20 PERCENT ONCE AGAIN ON WEDNESDAY...THEREBY INCREASING THE POTENTIAL
FOR FIRE WEATHER CONCERNS. MPJ
.EXTENDED...UPPER LEVEL RIDGE OF HIGH PRESSURE TO BEGIN TO BUILD
OVER CENTRAL MONTANA ON FRIDAY. THIS RIDGE OF HIGH PRESSURE SHOULD
REMAIN OVER THE AREA UNTIL LATE SUNDAY. AS A RESULT...EXPECT MOSTLY
DRY CONDITIONS THROUGH THE WEEKEND...WITH TEMPERATURES BECOMING HOT.
I HAVE GONE ABOVE GUIDANCE BUY A FEW DEGREES FOR THE WEEKEND. EXPECT
A CHANCE IN THE WEATHER LATE SUNDAY OR EARLY ON MONDAY...AS THE NEXT
PACIFIC COLD FRONT ARRIVES...AND THE UPPER LEVEL RIDGE MOVES EAST.
SO I HAVE A CHANCE FOR THUNDERSTORMS ON MONDAY...ALONG WITH A BIT
COOLER TEMPERATURES. FOR TUESDAY...EXPECT MAINLY A WESTERLY FLOW
ALOFT...FOR MOSTLY DRY WEATHER...AND NEAR NORMAL TEMPERATURES. BRUSDA
