AREA FORECAST DISCUSSION FOR WESTERN SD AND NORTHEASTERN WY
NATIONAL WEATHER SERVICE RAPID CITY SD
235 AM MDT FRI MAY 7 1999

NO MAJOR FORECAST CONCERNS FOR THE UPCOMING PACKAGE AS THE ETA/NGM
ARE IN BASIC AGREEMENT AND WINDS WILL CONTINUE THE DOWNWARD TREND.
FOR TODAY...CLOUDS AND WINDS WILL HANG ON THIS MORNING OVER CNTRL SD
AS THE UPPER LOW IS SLOW TO MOVE EAST. RAIN IS JUST ABOUT OVER AND
SHOULD BE ENDED BY ZONE RELEASE TIME OVER TRIPP COUNTY. 850 MB WINDS
ARE PROGGED TO DECREASE TO 10-25 KNOTS ACROSS THE CWA BY LATE THIS
AFTERNOON. QUIET WEATHER EXPECTED TONIGHT. THE MAIN MODEL DIFFERENCE
IS THAT THE NGM BRINGS A COLD FRONT INTO NERN WY AND FAR WRN SD WITH
850 MB WINDS OF 25-30 KNOTS. THIS IS NOT SUPPORTED BY THE UPPER-LEVEL
PATTERN OR BY THE ETA...SO IT WAS DISCOUNTED. ON SATURDAY...SOME
INSTABILITY TRIES TO RETURN TO NERN WY...BUT MOISTURE REMAINS FAIRLY
MEAGER (CURRENT SURFACE DEWPOINTS ARE IN THE TEENS AND 20S). WILL
LEAVE IN THE SMALL CHANCE OF THUNDERSTORMS OVER NERN WY...BUT HAVE
PUSHED BACK INTO LATE AFTERNOON. FINALLY...THE EXTENDED WAS NOT
CHANGED SINCE ONLY VERY LITTLE NEW GUIDANCE TO WORK WITH.

.UNR...NONE.
