AREA FORECAST DISCUSSION FOR WESTERN SD AND NORTHEASTERN WY
NATIONAL WEATHER SERVICE RAPID CITY SD 
305 AM MST SUN MAR 3 2002

9Z SURFACE ANALYSIS SHOWS SURFACE HIGH PARKED OVER EASTERN MONTANA. 
TEMPS ACROSS REGION HAVE TUMBLED TO BELOW ZERO DEGREES IN MOST 
AREAS. WARMER TEMPS ARE ON THE WAY. THETA E ADVECTION BEGINS AROUND 
MIDDAY ACROSS THE REGION. TEMPS TODAY SHOULD BE 10 TO 15 DEGREES 
WARMER THAN YESTERDAY. A SHORTWAVE MOVES NORTH OF THE REGION 
TONIGHT...WITH JUST A SLIGHT CHANCE OF SNOW FOR NORTHEASTERN 
WYOMING...THE BLACK HILLS...AND NORTH. MONDAY AND TUESDAY LOOK EVEN 
WARMER...WITH MOST AREAS FINALLY SEEING ABOVE AVERAGE TEMPS.

TEMPS A CONCERN FOR WEDNESDAY. MODELS SEND ANOTHER SHOT OF COOL AIR 
IN FROM CANADA...AND LOOKS LIKE STATIONARY BOUNDARY SETS UP RIGHT 
ACROSS THE REGION. WITH THE TENDENCY FOR MODELS TO NOT HANDLE 
SHALLOW COLD AIR VERY WELL...I WILL KNOCK TEMPS DOWN ON WEDNESDAY 
FOR ALL ZONES.

REMAINDER OF FORECAST LOOKS GOOD.

.UNR...NONE.
