Area forecast discussion, Aug 4, 12:40 PM MST, 7 hours 36 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE CHEYENNE WY 140 PM MDT TUE AUG 4 2009 .SHORT TERM...TONIGHT THROUGH THURSDAY QUESTION IN THE SHORT TERM WILL BE THE CHANCES OF THUNDERSTORMS AND THE POSSIBILITY OF SEVERE WEATHER THIS EVENING. LATEST GUIDANCE FROM SPC HAS THE PANHANDLE AND EXTREME EASTERN WY IN SLIGHT RISK. THIS AREA IS MAINLY ALONG THE HIGHER DEW POINT AXIS THAT EXTENDS FROM SOUTHWESTERN NEBRASKA NORTHWESTWARD INTO BILLINGS. CONCERN IS THAT THIS COULD BE A REPEAT OF LAST EVENING WHEN STORMS THAT DEVELOPED IN THIS SAME GENERAL AREA PRODUCED SEVERAL GUSTS IN EXCESS OF 70 MPH. THEREFORE WILL CONTINUE THE GOING FORECAST OF DAMAGING WINDS THIS EVENING IN THE SLIGHT RISK AREA. 19Z LAPS DATA SHOWING BULLSEYE OF CAPE AND -6 LI IN PLATTE COUNTY BUT RADAR IS PPINE WITH SOME SMALL RELATIVELY FLAT CUMULUS VISIBLE AROUND KCYS. MODELS IN GOOD AGREEMENT IN THE SHORT TERM SLOWLY TRANSITIONING AN UPPER RIDGE OVER THE CWA. THE RESULT OF THIS GIVES THE AREA A INCREASINGLY STRONGER UPPER SOUTHWESTERLY DIFLUENT FLOW. IN ADDITION MODELS SHOW INCREASING LOW LEVEL MOISTURE. THEREFORE THE ONGOING FORECAST CALLING FOR A CHANCE OF AFTERNOON AND EVENING THUNDERSTORMS SEEMS REASONABLE. CURRENT THINKING IS THAT THURSDAY WILL BE THE BEST CHANCE OF WIDESPREAD RAIN IN THE CWA. SEASONAL TO SLIGHTLY ABOVE TEMPERATURES WILL PERSIST. .LONG TERM...THURSDAY NIGHT THROUGH TUESDAY SW FLOW WILL BE ALOFT OVER THE CWA THURSDAY NIGHT AND FRI AS AN UPPER TROUGH MOVES OVER THE WESTERN U.S. A FEW DISTURBANCES WILL EJECT OUT OF THE UPPER LOW AND MOVE ACROSS THE FORECAST AREA THURSDAY EVENING AND FRIDAY AFTERNOON. WITH UNSTABLE AIRMASS OVER THE AREA AND MID LEVEL MOISTURE THESE DISTURBANCES WILL ENHANCE LATE DAY THUNDERSTORM DEVELOPMENT ACROSS THE CWA. DRY CONDITIONS WILL THEN PREVAIL FROM SAT THROUGH TUES AS THE UPPER TROUGH WEAKENS AS IT MOVES NORTHEAST INTO MT AND THEN ON INTO THE UPPER GREAT LAKES REGION. THE UPPER TROUGH WILL DRAG A COLD FRONT ACROSS THE AREA BY SAT AFT AND WITH UPSLOPE BEHIND FRONT ON SAT...MAY HAVE TO BOOST POPS DEPENDING ON TIMING. AN UPPER RIDGE WILL REBUILD OVER THE ROCKIES FROM SUN THROUGH TUES. HIGH TEMPERATURES WILL BE FROM 3 TO 5 DEGREES ABOVE NORMAL EACH DAY WITH THE EXCEPTION OF SUN...WHEN HIGHS WILL BE AROUND NORMAL. && .AVIATION...OUTSIDE OF THE ISOLATED THUNDERSTORMS THIS AFTERNOON AND EVENING VFR CONDITIONS WILL EXIST. AFTER 05/10Z SOME MVFR CONDITIONS SHOULD DEVELOP IN THE NEBRASKA PANHANDLE. && .FIRE WEATHER...SOME AREAS IN THE DISTRICT ARE APPROACHING CRITICAL VALUES. MOST AREAS IN THE HIGH COUNTRY ARE STILL GREEN. HOWEVER AT LOWER ELEVATIONS WILL NEED TO MONITOR VALUES CLOSELY. && .CYS WATCHES/WARNINGS/ADVISORIES... WY...NONE. NE...NONE. && SHORT TERM/AVIATION...GRIFFITH LONG TERM...KMD
