SOUTH CENTRAL AND SOUTHEAST COLORADO AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE PUEBLO COLORADO 230 PM MDT MON JUL 5 1999 ...FORECAST CHALLENGE IS AMOUNT OF THUNDERSTORM ACTIVITY TONIGHT AND TUESDAY... LATEST VISIBLE SATELLITE IMAGE AND LIGHTNING DISPLAY INDICATE ISOLATED CONVECTION FIRING ACROSS THE SOUTHERN MOUNTAINS AND EASTERN SAN LUIS VALLEY...WITH MUCH MORE EXTENSIVE ACTIVITY TO THE SOUTH OVER NEW MEXICO. STEERING CURRENTS EXTREMELY WEAK AS MOST STORMS DRIFT VERY SLOWLY TO THE SOUTH-SOUTHWEST. AT THE SURFACE...COLD FRONT THROUGH ALL BUT THE EXTREME SOUTHEAST CORNER...WITH STRONG NORTHEAST WINDS AND SLIGHT COOLING. DESPITE HIGH FWC POPS AND PRECIP MAX SEEN ON THE ETA...DEEP EASTERLY FLOW SUGGESTS ANY TSRA WILL BE LIMITED TO UPSLOPE REGIONS NEAR THE MOUNTAINS AND ACROSS THE SAN LUIS VALLEY. LITTLE CHANCE OF STORMS DEVELOPING OVER THE EASTERN PLAINS AFTER SUNSET WITH FROTNAL CONVERGENCE SOUTH OF THE AREA...WILL REMOVE POPS THESE AREAS. COULD SEE SOME PATCHY LOW CLOUDS BY MORNING...THOUGH NOT ENOUGH TO AFFECT MIN TEMPERATURES MUCH. SAME STORY TUESDAY WITH LOW LEVEL MOISTURE AND DEEP BUT WEAK EASTERLY FLOW IN PLACE. WILL MAINTAIN CHANCE POPS FOR MOUNTAINS... SLIGHT CHANCE ADJACENT AREAS...BUT WILL REMOVE POPS FOR THE EASTERN PLAINS AS NO UPPER SUPPORT TO PUSH STORMS EASTWARD. MAX TEMPS A LITTLE COOLER TUE...ESPECIALLY IF EARLY MORNING LOW CLOUDS ARE SLOW TO ERODE...THOUGH FWC NUMBERS LOOK TOO COOL GIVEN WARM 700 MB TEMPS AND WILL SHADE TOWARD WARMER FAN NUMBERS. TEMPS SHOULD REBOUND WED AS SURFACE WINDS BECOME SOUTHWESTERLY/DOWNSLOPE BY LATE IN THE DAY. STILL ENOUGH MOISTURE OVER THE MOUNTAINS TO RETAIN SLIGHT CHANCE POPS. EXTENDED...MRF DEPICTS UPPER RIDGE BUILDING OVER COLORADO THURSDAY THEN SLOWLY SHIFTING WESTWARD AND FLATTENING FRIDAY AND SATURDAY AS STRONG A S/W DIVES INTO THE NORTHERN PLAINS. THU LOOKS LIKE THE DRIEST/HOTTEST DAY OF THE EXTENDED...WITH FROPA AND UPSLOPE DEVELOPING FRI/SAT FOR INCREASING PRECIP CHANCES/SLIGHTLY COOLER TEMPS. ENOUGH MOISTURE TO KEEP PRECIP CHANCES IN THE MOUNTAINS ALL THREE DAYS. .PUB...NONE PETERSEN
