AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE DENVER CO 312 PM MDT SAT JUL 2 2005 .SHORT TERM...ISOLATED SHOWERS AND THUNDERSTORMS ARE CURRENTLY GOING OVER THE WESTERN TWO-THIRDS OF THE FORECAST AREA. DEW POINTS ARE IN THE 30S IN MOST AREAS SAVE THE FAR EASTERN BORDER WHERE SOME 40S ARE INDICATED. IN SPITE OF THEIR HIGH BASES...SOME RAIN IS ACTUALLY HITTING THE GROUND. MODEL DATA FOR THIS EVENING OFFERS LITTLE IN OPPOSITION TO THE CURRENT GOING REAL WEATHER...SO WILL KEEP POPS ISOLATED. NEED TO MAKE SURE OVERNIGHT LOWS ARE NOT TOO COOL WITH THE THICKNESS GRIDS...EXPECTED CLOUD COVER...AND THIS MORNINGS WARMTH IN MIND. ON SUNDAY...MODELS HAVE THE TAIL END OF AN UPPER TROUGH PUSH ACROSS THE FORECAST AREA EARLY SUNDAY INTO MID DAY. THIS USHERS IN A SURGE OF SOME UPSLOPE. IN SPITE OF THE TROUGH AND SURGE...THE LOW LEVELS ARE PROGGED TO STAY PRETTY DRY. BY LATER SUNDAY AFTERNOON AND INTO THE EVENING...A THETA-E AXIS GETS BACK INTO THE PLAINS FROM THE EAST. PROGGED BOUNDARY LAYER DEW POINTS ARE STILL ONLY IN THE 40S OVER THE FAR EAST BY 00Z SUNDAY AFTERNOON. CROSS SECTIONS DO SHOW PLENTY OF MIDDLE AND UPPER LEVEL MOISTURE AFTER MIDNIGHT TONIGHT CONTINUING THROUGH SUNDAY AFTERNOON. CAPES ARE FAIR ON SUNDAY AFTERNOON...THE HIGHEST OVER THE FAR EASTERN BORDER. THE QPF GRIDS ON BOTH MODELS SHOW A LITTLE BIT SUNDAY AFTERNOON. WITH ALL CONSIDERED... WILL GO WITH 10-20% POPS...MAYBE HIGHER IN THE EVENING? FOR TEMPERATURES...GO A BIT HIGHER FOR LOWS THAN MOS GUIDANCE SHOWS. ON SUNDAY READINGS LOOK ABOUT 3 TO 5 C COOLER THEN NOW. .LONG TERM...SUNDAY NIGHT INTO TUESDAY...MDLS MAINTAIN A WEAK TO MODERATE WEST TO NORTHWESTERLY FLOW ALOFT OVER THE CWFA. LOW LEVEL E TO SELY WINDS WILL OCCUR SUNDAY NIGHT INTO MONDAY FOLLOWING THE PASSAGE OF A WEAK FRONTAL BOUNDARY. AS IT DOES...LOW LEVEL MSTR INCREASES AS THE LOW LEVEL THETA-E MSTR ADVECTS BACK INTO THE CWFA. FCST SOUNDINGS INDICATE CAPES RANGING FROM 1400-1700 J/KG DURING THE LATE AFTN AND EVENING WITH SOME MINIMAL CIN. A WEAK UPPER LEVEL DISTURBANCE IN THE FLOW IS ALSO PROGGED TO SLIP ACROSS NRN COLORADO SUNDAY NIGHT. FVBL ENOUGH SHEAR PROFILE AS WELL FOR AN ISOLD SVR STORMS. MONDAY AGAIN LOOK GOOD ALTHOUGH SELY WINDS WILL AID IN THE DEVELOPMENT OF A DENVER CYCLONE. FCST CAPES RANGE FM 1700-2000 J/KG ALONG THE FRONT RANGE AND PALMER DIVIDE TO 3400 J/KG IN THE NE CORNER OF THE STATE AS WELL. SHEAR PROFILE IS BETTER TOO VS SUNDAY NIGHT...ESPECIALLY IN THE NORTHEAST PLAINS. AS A RESULT THE BEST CHC OF SVR STORMS MAY BE ON MONDAY. THE GFS MAINTAINS LOW LEVEL THETA-E MSTR OVER THE NORTHEAST PLAINS THROUGH AT LEAST THURSDAY. A WEAK UPPER LEVEL DISTURBANCE IS PROGGED TO CLIP NORTHEAST COLORADO TUESDAY AFTN AND EVENING...AND THIS COULD BE THE TRIGGER FOR MORE THUNDERSTORMS IN THE PLAINS. NO BIG CHANGES TO THE EXTENDED AT THIS TIME WITH A SLIGHT CHANCE OF POPS THROUGH FRIDAY...ESPECIALLY FOR THE NORTHEAST PLAINS IN THE AFTN AND EVNG. && .BOU...NONE. && KOOPMEINERS/COOPER
