209 PM MDT TUE AUG 3 2004

.SHORT TERM...TODAY THROUGH WEDNESDAY NIGHT...MODELS IN GOOD
AGREEMENT WITH SOUTHWEST FLOW ALOFT, WEAK UPPER LEVEL DISTURBANCES
AND LIMITED AVAILABLE MOISTURE. FORECAST CHALLENGE HAS BEEN THE
TIMING OF CONVECTION FOR TOMORROW EVENING. WILL ALSO NEED TO
CONTINUE EVALUATION OF DRY THUNDERSTORM POTENTIAL. THINK THERE IS A
GOOD CHANCE THAT SOME OF THE THUNDERSTORMS THAT FORM  TOMORROW
AFTERNOON MAY HAVE VERY LITTLE PRECIPITATION. THINK THERE IS ENOUGH
RESIDUAL MOISTURE TODAY TO HAVE SHOWERS WITH AFTERNOON CONVECTION.

.LONG TERM...THURSDAY THROUGH TUESDAY...THURSDAY INTO FRIDAY CONTINUE
TO LOOK GOOD FOR THUNDERSTORM DEVELOPMENT. UPPER LEVEL SOUTHWEST
FLOW WITH A MODIFIED MARINE PUSH AND THE THERMAL TROUGH LINGERING ALL
LOOK TO ALLOW FOR DECENT STORM STRENGTH. ALSO THE JET STREAM LOOKS TO
ADD SOME DYNAMIC ENHANCEMENT...FURTHER AIDING STORM DEVELOPMENT. AS
OF NOW IT LOOKS AS IF THE STRONGER STORMS WILL BE ACROSS NORTHWEST
MONTANA THURSDAY AS THE MARINE PUSH INTERACTS WITH THE THERMAL
TROUGH AND ACROSS SOUTHWEST MONTANA FRIDAY AS THE COLD FRONT PUSHES
THROUGH. LATE FRIDAY EVENING THE SURFACE COLD FRONT WILL HAVE PUSHED
THROUGH...MAKING FOR A CHANCE OF POST FRONTAL SHOWERS...MAINLY
ACROSS NORTHWEST MONTANA AND COOLER TEMPERATURES. SUNDAY THROUGH
TUESDAY AN UPPER LEVEL RIDGE OF HIGH PRESSURE WILL MAKE FOR A WARMING
AND DRYING TREND.
