AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE CHEYENNE WY 207 PM MDT MON SEP 1 2008 .SHORT TERM...TONIGHT THROUGH WEDNESDAY... A STRONG UPPER LEVEL TROUGH CONTINUES TO IMPACT THE NORTHERN ROCKIES AND WILL CONTINUE TO BE PRESENT THROUGH THE EVENING HOURS ACROSS THE FORECAST AREA BEFORE IT MOVES NORTHEAST OF THE AREA. A SIGNIFICANT DRY SLOT MOVED OVER MOST OF SOUTHEAST WYOMING EARLY THIS MORNING AND INTO THE NEBRASKA PANHANDLE THIS AFTERNOON. THIS HAS RESULTED IN MUCH LESS PRECIPITATION THAN EARLIER EXPECTED DURING THE LABOR DAY PERIOD...BUT ALSO IS PROVIDING GOOD DAYTIME HEATING THAT COULD LEAD TO SLIGHTLY BETTER INSTABILITY LATE THIS AFTERNOON AND EVENING. CARBON COUNTY HAS BEEN RECEIVING PRECIPITATION FOR MOST OF THE DAY...AS THIS AREA WAS ALREADY BENEATH THE BAND OF RAINFALL LOCATED CLOSER TO THE SUPPORT FROM THE UPPER TROUGH. THE CLOUD COVER AND PRECIPITATION THERE HAVE COMBINED TO CREATE A VERY COOL AND RAINY DAY...WITH TEMPERATURES NOT LIKELY TO RISE BEYOND POSSIBLY 50 DEGREES LATE THIS AFTERNOON. WHILE LAPS CAPE VALUES HAVE BEEN INCREASING IN THE PANHANDLE EARLY THIS AFTERNOON...LAPS LIFTED INDICES VALUES CONTINUE TO SHOW THE LOWER ATMOSPHERE REMAINING QUITE STABLE WITH +2 TO +3 VALUES FOR THE LIFTED INDEX. A FEW WEAK SHOWERS AND THUNDERSTORMS HAVE MOVED OFF THE LARAMIE RANGE ACROSS NORTHERN LARAMIE COUNTY EARLY THIS AFTERNOON...AND A TREND TOWARD SCATTERED SHOWERS AND THUNDERSTORMS SHOULD CONTINUE AS THE DIFLUENCE AHEAD OF THE UPPER TROUGH AND THE 90 TO 100 KNOT JET STREAK MOVES GENERALLY NORTH ACROSS CENTRAL WYOMING LATE THIS AFTERNOON...AND THE ENHANCING AFFECTS OF THE RIGHT ENTRANCE REGION TO THE JET STREAK GET CLOSER TO THE FORECAST AREA. THE STORM PREDICTION CENTER HAS REMOVED THE FORECAST AREA FROM THE SLIGHT RISK FOR SEVERE THUNDERSTORMS TODAY AND TONIGHT...BUT A FEW STORMS AHEAD OF THE COLD FRONT MAY BRIEFLY BECOME STRONG WITH SMALL HAIL...MODERATE RAINFALL AND GUSTY WINDS. THE COLD FRONT HAS ALREADY MOVED THROUGH THE DOUGLAS AREA EARLY THIS AFTERNOON AND WILL MOVE SOUTH ACROSS THE FORECAST AREA FAIRLY QUICKLY THROUGH MID-EVENING. WITH THE FRONTAL PASSAGE...EXPECT STRONG AND GUSTY NORTHWEST WINDS TO DEVELOP. BELIEVE THAT THE WIND SPEEDS IN THE NEBRASKA PANHANDLE WILL ONLY APPROACH THE 30 MPH WIND ADVISORY CRITERIA. EVENING SHIFT WILL NEED TO MONITOR IN CASE THE WINDS BECOME STRONGER THAN EXPECTED...AND AN ADVISORY MAY BECOME NECESSARY FOR THE EVENING HOURS FOLLOWING THE FRONTAL PASSAGE. HAVE MENTIONED PATCHY FROST ACROSS THE LOWER ELEVATIONS OF ALBANY AND CARBON COUNTIES OVERNIGHT INTO EARLY TUESDAY AS FORECAST LOW TEMPERATURES SHOULD DROP BELOW 36 DEGREES. THE AVERAGE FIRST FROST AT LARAMIE IS ACTUALLY SEPTEMBER 1ST ACCORDING TO THE XMACIS CLIMATE DATA PROGRAM...SO A FROST THIS EARLY IS NOT UNUSUAL AROUND THE LARAMIE AREA. FOLLOWING THE FRONTAL PASSAGE AND THE EXIT OF THE UPPER LEVEL TROUGH OVERNIGHT...TEMPERATURES TUESDAY WILL BE AROUND 8 TO 15 DEGREES COOLER THAN NORMAL WITH DRY CONDITIONS EXPECTED. A SHORT- WAVE RIDGE AND RETURN TO SOUTHWEST FLOW ALOFT WILL KEEP DRY CONDITIONS IN PLACE FOR WEDNESDAY WITH A SLIGHT WARMING TREND TO ONLY AROUND 5 DEGREES COOLER THAN NORMAL. LOW CLOUDS WILL BE POSSIBLE EARLY WEDNESDAY AS LINGERING MOISTURE WILL BANK UP AGAINST THE HIGHER TERRAIN DUE TO UPSLOPE FLOW TOWARD ANOTHER DEVELOPING LEE TROUGH. .LONG TERM...WEDNESDAY NIGHT THROUGH MONDAY... SOMEWHAT COOLER THAN AVERAGE CONDITIONS EXPECTED OVER THE CWA FOR MOST OF THE PERIOD AS AREA WILL BE UNDER GENERALLY NORTHWEST FLOW ALOFT ON WESTERN SIDE OF BROAD CYCLONIC UPPER FLOW. THIS WILL ALLOW FOR PERIODIC SHORTWAVES AND PUSHES OF COOLER AIR TO MOVE OVER THE REGION FROM CANADA. BEST CHANCES FOR PRECIPITATION WILL ACCOMPANY THE PASSAGE OF SHORTWAVES IN THIS UPPER FLOW...WITH FRIDAY HAVING THE BEST OPPORTUNITY DURING THE PERIOD. OTHER WEAKER IMPULSES WILL PASS BY MAINLY TO THE NORTHEAST OF THE CWA BUT CANNOT RULE OUT A FEW SHOWERS WITH THESE AS WELL. SOME WARMING POSSIBLE EARLY NEXT WEEK AS UPPER RIDGE OVER THE FAR WESTERN CONUS BEGINS TO SHIFT EASTWARD WHILE WEAKENING...VEERING UPPER FLOW TO MORE WESTERLY OVER THE REGION. && .AVIATION... AREAS OF MVFR AND LOCALIZED IFR CEILINGS WILL CONTINUE TO BE PRESENT FROM NEAR KRWL TO KDGW THIS AFTERNOON. EXPECT MVFR CONDITIONS TO SPREAD EASTWARD THIS EVENING AS SHOWER AND THUNDERSTORM ACTIVITY INCREASES INTO THE NEBRASKA PANHANDLE. A COLD FRONT WILL CONTINUE TO MOVE SOUTHEAST ACROSS THE AREA LATE THIS AFTERNOON AND INTO THE EVENING PRODUCING STRONG AND GUSTY NORTHWEST WINDS. EXPECT THE LOW CLOUDS AND STRONG WINDS TO EXIT THE AREA BY EARLY TUESDAY MORNING. && .CYS WATCHES/WARNINGS/ADVISORIES... WY...NONE. NE...NONE. && SHORT TERM/AVIATION...CARPENTER LONG TERM...RE
