AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE PUEBLO CO 332 PM MDT MON MAY 2 2011 .SHORT TERM... (TONIGHT AND TUESDAY) SHORT TERM METEOROLOGICAL CONCERNS ARE ONE MORE NIGHT OF UNSEASONABLY COOL TEMPERATURES AND DECREASING SHOWERS. FAR EASTERN PORTIONS OF THE CWFA CURRENTLY NOTING ISOLATED SHOWERS AND EVEN A FEW THUNDERSTORMS WHILE HIGHER ELEVATIONS NOTED SOME SNOW SHOWERS. ALSO...A FEW COLD AIR FUNNELS WILL ALSO BE POSSIBLE THIS AFTERNOON AND EVENING. IN ADDITION...BELOW SEASONAL TEMPERATURES ARE BEING REPORTED IN COMBINATION WITH WIND GUSTS TO AROUND 30 MPH AT TIMES OVER FAVORED HIGHER TERRAIN AREAS. ANOTHER COLD NIGHT ANTICIPATED OVER THE INTERSTATE 25 CORRIDOR AND THE SOUTHEASTERN PLAINS TONIGHT...THEREFORE WILL CONTINUE WITH EXISTING FREEZE WARNING FROM 2 AM TO 9 AM TUESDAY FOR ZONES 83>89 AND 93>99. LATEST REAL-TIME DATA AND MODEL SIMULATIONS SUGGEST THAT SHOWERS WILL BE ON A DECREASING TREND THIS EVENING WITH CWFA BECOMING DRY AFTER MIDNIGHT. DRY CONDITIONS TO CONTINUE ON TUESDAY AS WEAK TRANSITORY UPPER RIDGE DEVELOPS OVER AREA. MAXIMUM TEMPERATURES ON TUESDAY SHOULD RUN SOME 9F TO 16F DEGREES WARMER THAN VALUES NOTED TODAY. FINALLY...GRADIENT WINDS SHOULD REMAIN RELATIVELY WELL-BEHAVED OVER THE CWFA TONIGHT AND AGAIN ON TUESDAY. .LONG TERM... (TUESDAY NIGHT THROUGH MONDAY) ...QUIET WX... NOT TOO MUCH TO WRITE ABOUT DURING THIS FCST TIME PERIOD. FLOW ALOFT WILL GENERALLY BE ZONAL AND THE MAIN CORE OF THE JET WILL BE TO THE NORTH OF THE CWA. THIS PATTERN WILL KEEP THINGS QUITE DRY OVER THE FCST AREA WITH TEMPERATURES TRENDING TOWARDS ABOVE NORMAL VALUES FOR THIS TIME OF THE YEAR. A WEAK COOL FRONT WILL MOVE ACROSS THE REGION WED MORNING...HOWEVER THIS BOUNDARY WILL LIKELY BE DRY. THE ONLY CHANCE OF ANY PRECIP WILL BE ACROSS THE C MTNS AND POSSIBLY THE PALMER DVD. THE REMAINDER OF THE FCST HAS DRY WX ACROSS THE ENTIRE REGION EXCEPT FOR SOME LOW POPS ACROSS THE C MTN REGION ON SATURDAY AND POSSIBLY NEXT MONDAY. TEMPS WILL GRADUALLY BE RAMPING UP INTO THE 80S STARTING ON FRIDAY. WITH MID LVL FLOW ON THE WEAKER SIDE...I DO NOT SEE ANY FIRE WX CONCERNS DURING THIS PD. THE LONGER RANGE MODELS ARE SHOWING SOME PROMISE FOR MID WEEK NEXT WEEK (BIG CUTOFF ON THE EC MODEL). HOPEFULLY WE WILL SEE SOME RUN TO RUN CONSISTENCIES WITH THIS FEATURE DURING THE NEXT SEVERAL DAYS. \/HODANISH && .AVIATION...
