Area forecast discussion, Jun 29, 1:52 PM MDT, 2 hours 45 minutes before
SOUTH CENTRAL AND SOUTHEAST COLORADO AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE PUEBLO CO 150 PM MDT SUN JUN 29 1997 THE PRIMARY FORECAST PROBLEM OF THE NIGHT IS DETERMINING IF DEEP CONVECTION WILL BE SUSTAINED ON THE FAR EASTERN PLAINS. THUNDERSTORMS OVERNIGHT IN KANSAS PRODUCED ENOUGH OUTFLOW THAT THE LOWER ATMOSPHERE OVER EASTERN COLORADO WAS SUBSTANTIALLY MODIFIED. THE COOL...MOIST AIR HAS SLOWED AND LIMITED HEATING ON THE PLAINS TODAY. MEANWHILE...THE MODELS INDICATE A TREND TOWARD WARMING MID LEVELS OVER THE NEXT 24 HOURS AS AN UPPER RIDGE BUILDS OVER THE REGION. THUS...THE RACE IS ON BETWEEN DAYTIME HEATING ACTING ON HIGH LOW LEVEL MOISTURE OVER THE EASTERN PLAINS AND STABILIZING DUE TO MID LEVEL WARMING. THE ETA SHOWS 1000+ J/KG CAPE AND RELATIVELY LOW CIN...BUT DOES NOT GENERATE ANY PRECIPITATION. CONVECTION HAS BEEN FAIRLY SHALLOW AS OF EARLY AFTERNOON. HOWEVER...IT IS HARD TO IMAGINE THAT AS TEMPERATURES CLIMB INTO THE LOWER 90S OVER THE FAR EASTERN PLAINS...WITH DEWPOINTS IN THE MID 50S...THAT DEEP CONVECTION WILL NOT DEVELOP. VERTICAL WIND SHEAR IS SUFFICIENT (AROUND 30- 40 KTS THRU THE LOWEST 4 KM) TO ORGANIZE THE STORMS SOMEWHAT... AND DRYING MID LEVELS WILL HELP ALLOW STRONG DOWNDRAFTS. WARM TEMPERATURES ALOFT SHOULD MOSTLY INHIBIT HAIL PRODUCTION. COVERAGE OF THUNDERSTORMS THIS AFTERNOON AND EVENING WILL BE LIMITED...SINCE THERE APPEARS TO BE NO UPPER LEVEL FEATURE TO HELP TRIGGER AND SUSTAIN CONVECTION. HOWEVER...A DRYLINE IS IN PLACE EXTENDING THROUGH HUERFANO AND LAS ANIMAS COUNTIES... WHICH MAY HELP TO TRIGGER THUNDERSTORMS THIS AFTERNOON AND EVENING. WITHOUT UPPER LEVEL SUPPORT...STORMS SHOULD DIE OUT BEFORE MIDNIGHT. WITH INCREASING SOUTHWEST FLOW IN THE MID LEVELS APPROACHING FROM THE WEST...SURFACE WINDS HAVE INCREASED IN THE SAN LUIS VALLEY THIS AFTERNOON AND THESE WINDS SHOULD PERSIST THROUGH MUCH OF THE EVENING BEFORE DIMINISHING. FWC TEMPER ATURES AND POPS ARE IN THE BALLPARK. HAYNES
