OF ML CAPE IN W SD AND IR/VIS IMAGERY HAS SHOWN RAPIDLY COOLING AND
EXPANDING CLOUD TOPS IN SE MT SOUTH TO NE WY WHERE MOD TO HEAVY RAINS
ARE ONGOING. MOISTURE HAS WRAPPED INTO DISCUSSION REGION PER BLENDED TPW
PRODUCT WITH PWATS NEARING 1.1-1.2" AND VWPS`S INDICATE MODEST 15-20 KNOT
SE FLOW INTO DISCUSSION REGION. GENERALLY EXPECT RATES OF .25.-75"/HR
BUT ISOLATED 1"/HR RATES POSSIBLE, ESPECIALLY IN CELL MERGERS.
.
SHORT TERM OUTLOOK VALID 0000-0300Z...MEDIUM CONFIDENCE FACTOR
IN SHORT TERM OUTLOOK...GIVEN RECENT TRENDS IN IR/VIS IMAGERY EXPECT
SHOWERS TO CONTINUE FOR AT LEAST THE NEXT 3 HOURS WITH RATES APPROACHING
.5-1.0"/HR IN MERGERS/DEEPEST CORES. WITH 3 HR FFG IN POCKETS OF THE
DISCUSSION REGION  AROUND 1-1.5" THE REGION COULD HAVE FF ISSUES GIVEN
RATES APPROACHING THESE VALUES.
