1000 AM MDT MON MAY 9 2005

.DISCUSSION...
LATEST RADAR LOOP SHOWING HEAVY SHOWERS ACROSS WESTERN ID. THIS
ACTIVITY ASSOCIATED WITH SFC FRONT AND UPPER DIVERGENCE FROM 3H JET.
ACTIVITY WILL GRADUALLY SPREAD EAST DURING THE DAY. TWO CONCERNS FOR
AFTERNOON/TONIGHT. THE FIRST WX PROBLEM WILL BE POSSIBLE SVR LATE
THIS AFTERNOON. AREA BECOMES UNSTABLE AND FRONT TRACKS INTO THE
AREA...BUT...THE SFC FRONT WEAKENS CONSIDERABLY (SFC CONVERGENCE) AS
IT MOVES INTO FCST/A LATE THIS AFTERNOON AND IF CLOUD COVER REMAINS
THIS WILL INHIBIT HEATING/CONVECTION. WILL MENTION HVY RAIN AND
SMALL HAIL FOR AFTN/EVE CONVECTION FOR NOW. THE OTHER PROBLEM WILL BE A
SECONDARY QPF MAX THAT DEVELOPS ACROSS EASTERN ZONES TONIGHT WHICH
AGAIN COULD LEAD TO LOCALLY HEAVY RAIN. THIS ACTIVITY WILL BE
ENHANCED BY SFC-7H TROF AND STRONG DIVERGENCE ALOFT (3H JET
COUPLET). HAVE ADDED HVY RAIN WORDING FOR MOST ZONES TONIGHT.
OTHERWISE FCST IN GOOD SHAPE.
