SOUTH CENTRAL AND SOUTHEAST COLORADO AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE PUEBLO COLORADO 200 PM MDT THU JUL 12 2001 POSSIBILITY OF HEAVY RAIN TONIGHT IS THE MAIN CONCERN. DEW POINTS EARLY THIS AFTERNOON OVER THE SOUTHEAST PLAINS WERE IN THE UPPER 40S TO LOWER 50S. MODELS ARE SHOWING 15 TO 20KTS OF EASTERLY FLOW AT 850MB LATE THIS AFTERNOON AND THROUGH THE EVENING HOURS. AT 700MB THE WINDS ARE EASTERLY AS WELL BUT MORE LIKE 5 TO 10 KTS. THIS EASTERLY FLOW SHOULD HELP KEEP THUNDERSTORMS DEVELOPING... ESPECIALLY ALONG AND NEAR THE EASTERN MTNS THROUGH THE EVENING. 500MB FLOW IS FORECAST TO BE WEST TO SOUTHWEST AT 10 TO 20 KTS AND STORMS SHOULD MOVE EAST OR NORTHEAST AS A RESULT. PW VALUES ARE EXPECTED TO BE ON THE INCREASE. WITH THE LOW-LEVEL EASTERLY FLOW AND THE REDEVELOPMENT OF STORMS...SOME AREAS COULD HAVE HEAVY RAIN A FEW TIMES THIS EVENING AND THIS IS THE MAIN CONCERN. THE LOW LEVEL FLOW IS EXPECTED TO DECREASE OVER THE EASTERN PLAINS BY ABOUT 06Z. COULD SEE AN MCS OVER THE SE CO PLAINS TONIGHT...MOVING SLOWLY EASTWARD. THIS COULD MEAN A CHANCE FOR PRECIP THROUGH THE NIGHT FOR THE FAR EAST PLAINS. SPC HAS THE SOUTHEAST PLAINS IN A SLIGHT RISK FOR SEVERE WEATHER AS WELL. ON FRIDAY THE STRONGER LOW LEVEL EASTERLY FLOW IS EXPECTED TO HAVE SHIFTED SOUTH INTO NM...AND THE 700MB FLOW SHOULD BE LIGHT SOUTHWESTERLY. MOISTURE OVER THE AREA SHOULD STILL BE GOOD WITH PW'S OF AROUND 1.2 INCHES. WITH THE ABUNDANT MOISTURE...BOUNDARIES FROM THE CONVECTION TONIGHT...AND DAYTIME HEATING...WE WILL AGAIN SEE SHOWERS AND THUNDERSTORMS DEVELOP WITH SOME HEAVY RAIN POSSIBLE AGAIN. TEMPS ON FRIDAY WILL LIKELY BE A BIT COOLER. ON SATURDAY THE UPPER HIGH IS EXPECTED TO SHIFT A LITTLE EASTWARD WHICH WOULD DRY US OUT A LITTLE. A SHORTWAVE IS EXPECTED TO MOVE ACROSS THE AREA DURING THE DAY TO PROVIDE SOME ADDED LIFT. THERE WILL STILL BE ENOUGH MOISTURE OVER THE AREA FOR A CHANCE OF AFTERNOON AND EVENING THUNDERSTORMS. TEMPS LOOK A LITTLE WARMER AGAIN THIS DAY. SATURDAY NIGHT THE THUNDERSTORMS SHOULD BE MAINLY IN THE EVENING HOURS WITH PARTLY CLOUDY OVERNIGHT. EXTENDED (SUN-THU): SUNDAY THE UPPER HIGH WILL SHIFT EVEN FARTHER EAST AS AN UPPER TROUGH MOVES OVER THE WEST COAST. THE FLOW OVER CO WILL BECOME WEST TO SOUTHWEST AND WILL ALLOW DISTURBANCES TO MOVE OVER THE AREA FROM THE SOUTHWEST. THIS WILL BE THE CASE THROUGH TUESDAY. GENERAL TROUGHINESS WILL REMAIN TO OUR WEST WITH THE UPPER RIDGE OVER THE SOUTH CENTRAL PLAINS THROUGH THURSDAY. THE MOISTURE THROUGH THE PERIOD IS NOT SIGNIFICANT...BUT SHOULD BE ENOUGH TO KEEP SLIGHT CHANCE WORDING IN THE FORECAST EACH DAY. PUB...NONgE.
