EVENT...1-HR STLT ESTIMATES OF 0.4-0.5" RAINFALL INDICATED FROM TSTMS
.
SATELLITE ANALYSIS AND TRENDS...A CLOUD SHIELD WITH CLOUD TOP TEMPS
REACHING UPWARDS OF -64C TO -65C CAN BE EASILY IDENTIFIED IN IR
IMAGERY STRETCHING FROM VIC OF HLN NWD TO GTF THEN EWD TO JUST SW
OF JDN.  THIS CLOUD SHIELD HAS DEVELOPED RATHER NICELY IN A REGION OF
ENHANCED UPPER-LVL DIFFLUENCE (FIRST MENTIONED IN EARLIER 2222Z SPENES).
EXPERIMENTAL UPPER-LVL DIVERGENCE PLOT USING GOES STLT WINDS SHOWS A
NICE MAX REGION OF DIVERGENCE CENTERED ACROSS NW MT/CANADIAN BORDER.
BASED ON 00Z RAOB FROM TFX...EL IS AT -60C..SO IT APPEARS LIKELY THAT THE
TSTMS MOVING NNEWD ACROSS CENTRAL MT ARE LIKELY PRODUCING MOD/HVY RAINS.
1-HR STLT ESTIMATES ENDING AT 2345Z INDICATE 0.4-5.0" OF RAINFALL FELL
ACROSS S POWELL/DEER LODGE/S LEWIS AND CLARK COUNTIES.
.
MOD/HVY RAINS ARE EXPECTED TO CONTINUE TO PUSH NNEWD INTO NORTH-CENTRAL
MT INTO THE EARLY EVENING HRS.  STORMS WILL LIKELY CONTINUE TO BE
CAPABLE OF PRODUCING AROUND 0.5" OF RAINFALL AS MID-UPPER LVL SUPPORT
FROM EWD MOVING S/WV ACROSS W MT..UPPER-LVL DIFFLUENCE SHOULD PERSIST
OVER THE NEXT SEVERAL HRS CONTRIBUTING TO ENHANCED VERTICAL MOTIONS.
AREAS TO BE AFFECTED IN NEXT FEW HRS ARE INVOF CHOUTEAU/FERGUS/HILL/
BLAINE/PHILLIPS/PETROLEUM COUNTIES IN N-CENT MT.
