Area forecast discussion, Jul 23, 2:18 PM MDT, 1 hour 38 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE PUEBLO CO 218 PM MDT SUN JUL 23 2006 .SHORT TERM... (TONIGHT AND MONDAY) HIGH PRESSURE ALOFT OVER UTAH DRIFTING SOUTHWARD TODAY WITH WEAK SHORT WAVES EMBEDDED IN THE FLOW. MID-UPPER LEVEL MOIST PLUME MOVING THROUGH THE FLOW WITH ISOLATED CONVECTION OVER CENTRAL MOUNTAINS AND MOVING SOUTH. DO NOT EXPECT A REPEAT OF WHAT HAPPENED SATURDAY OVER THE SAN JUANS BUT STILL WILL NEED TO KEEP AN EYE ON THAT AREA FOR SOME LOCALLY HEAVY RAIN. TONIGHT...RIDGE DRIFTS TO 4-CORNERS BUT SHORT WAVES CONTINUE TO RIPPLE AROUND THE HIGH KICKING OFF -TSRA OVER THE HIGH TERRAIN THROUGH THE EVENING. EXPECTING MOST THUNDERSTORMS TO STAY CLOSE TO THE HIGH TERRAIN AS THEY MOVE TO THE SOUTH AND SOUTHWEST BUT ACTIVITY SHOULD WEAKEN AFTER SUNSET. MODELS SHOW ANOTHER SHORTWAVE ROUNDING THE TOP OF THE UPPER RIDGE AND INTO EASTERN COLORADO OVERNIGHT. GFS AND NAM SHOW POT VORT SLIPPING DOWN THE EASTERN PLAINS. RH/PRECIP PROBABLY OVERDONE ON MODELS AND CONSIDERING DIURNAL TRENDS WILL HOLD OFF ON POPS FOR NOW OTHER THAN TO INCREASE CLOUD COVER A LITTLE. MONDAY...PRETTY SIMILAR TO SUNDAY ALTHOUGH UPPER RIDGE DOES FLATTEN A BIT AS SHORT WAVES RIPPLES TO OUR NORTH. ISOLATED TO SCATTERED THUNDERSTORMS OVER HIGH TERRAIN. WEAK LEE TROF SETS UP OVER EASTERN PLAINS BY AFTERNOON. CURRENT GRIDS LOOK PRETTY GOOD AND MATCH UP WITH LATEST GUIDANCE. NAM A LITTLE SLOWER AND WEAKER WITH SHORT WAVE DROPPING ACROSS EASTERN PLAINS ON MONDAY SO KEPT LOW POPS OVER MOUNTAINS AND ADJACENT LOWER ELEVATIONS. -WFF- .LONG TERM... (MONDAY NIGHT THROUGH SUNDAY) NAM...GFS AND ECMWF MODELS ALL INDICATE THAT AN UPPER RIDGE REMAINS OVER THE SOUTHWESTERN U.S. THROUGH THE WEEK...THEN THE UPPER PATTERN SHIFTS TO A MORE WESTERLY ZONAL FLOW OVER THE NEXT WEEKEND. THE RIDGE AXIS OR CENTROID LOOKS TO BE SITUATED OVER THE UT AND AZ BORDER THROUGH WED...THEN IT SLIDES TOWARDS NV THU AND FRI BEFORE FLATTENING OUT FOR THE WEEKEND. THE MODELS IMPLY THAT THE RIDGE WILL BE DIRTY...IN THAT MONSOON MOISTURE WILL SNEAK UP OVER THE 4 CORNERS AND PROVIDE THE FUEL FOR DAILY CONVECTION OVER THE HIGHER TERRAIN DURING THE AFTN...AND THE WESTERN HALF OF THE CWA BY THE EARLY EVENING. THERE ARE MULTIPLE UPPER DISTURBANCES ROTATING AROUND THE RIDGE WHICH WILL VERY DIFFICULT TO PINPOINT...BUT THE MODELS DO LATCH UPON A SHORTWAVE WED NIGHT AND THU. AS THE RIDGE SLIDES TO THE WEST...THIS WILL ALLOW THE SHORTWAVE TO AFFECT THE E HALF OF COLORADO...INCREASING PCPN CHANCES AND CLOUD COVER. THEREFORE...THOUGH THE E PLAINS WILL SEE A THREAT OF ISOLATED CONVECTION EACH DAY...THE BEST SHOT FOR PCPN THERE WILL BE WED NIGHT. OVERALL...VERY FEW ADJUSTMENTS NEEDED TO THE ONGOING FORECAST GRIDS. LOOK FOR ABOVE NORMAL TEMPS...WITH A DAILY CHANCE OF AFTN AND EVE CONVECTION FIRING OVER THE HIGHER TERRAIN AND THEN ROLLING ACROSS THE IMMEDIATELY ADJACENT PLAINS.
