AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE CHEYENNE WY 531 PM MDT TUE JUL 19 2011 .AVIATION...00Z TAFS LATEST RADAR IMAGERY SHOWING STRONG STORMS ACROSS NORTHERN COLORADO...POISED TO CROSS THE STATE LINE INTO WYOMING NEAR CHEYENNE. VARIOUS OUTFLOW BOUNDARIES FROM EARLIER STORMS EVIDENT SOUTH AND EAST OF CHEYENNE AND THESE COULD BE THE FOCUSING MECHANISMS FOR ADDITIONAL THUNDERSTORM DEVELOPMENT LATER THIS EVENING. THUNDERSTORM COVERAGE SHOULD DECREASE WITH SUNSET...BUT SOME COULD PERSIST AROUND CHEYENNE AND LARAMIE THROUGH MIDNIGHT LOCAL...06Z. WILL CONTINUE TO MONITOR AND WILL AMEND TAFS AS NEEDED. CLAYCOMB && .PREV DISCUSSION... /ISSUED 353 PM MDT TUE JUL 19 2011/ SHORT TERM...TONIGHT THROUGH THURSDAY... SOME SHOWERS AND THUNDERSTORMS HAVE FORMED EARLY THIS AFTERNOON ALONG AND WEST OF THE LARAMIE RANGE. THE ACTIVITY IS UNDER THE MID AND UPPER LEVEL MOISTURE PLUME AT THAT TIME. ONCE AGAIN THROUGH EARLY TONIGHT...THE ACTIVITY WILL PRODUCE A PERIOD OF HEAVY RAIN... WIND GUSTS TO 50 MPH...SMALL HAIL AND CONSIDERABLE LIGHTNING. THE ACTIVITY WILL SPREAD EAST ACROSS AT LEAST ALL OF SOUTHEAST WYOMING THROUGH THIS EVENING AND THEN ACROSS THE PANHANDLE. THE SHOWERS AND STORMS WILL THEN SLOWLY DECREASE IN COVERAGE AND INTENSITY LATER TONIGHT. THE CURRENT GUSTY WINDS OVER THE CWA WILL EASE WITH SUNSET. THE SYNOPTIC PATTERN WILL CHANGE OVER THE REGION STARTING LATE TONIGHT AND CONTINUING THROUGH THURSDAY. A SHORTWAVE TROUGH CURRENTLY OVER THE PACIFIC NORTHWEST WILL CONTINUE TO SLOWLY WEAKEN AND LIFT NORTHEAST AND ACROSS THE NORTHERN HIGH PLAINS TONIGHT. THAT FEATURE TURNS THE FLOW ALOFT TO MORE WESTERLY AND HELPS TO PUSH A COLD FRONT ACROSS THE CWA LATE TONIGHT AND WEDNESDAY MORNING. THE COMBINATION WILL BRING DRIER AIR TO THE REGION FOR WEDNESDAY AND WEDNESDAY NIGHT. THE MID AND UPPER LEVEL MOISTURE PLUME WILL BE PUSHED SOUTH AND EAST OF THE CWA DURING THAT TIME. IN ADDITION...THE BOUNDARY LAYER DRIES WITH SURFACE DEW POINTS MUCH LOWER THAN CURRENT. ALSO BEHIND THE FRONT WILL BE COOLER TEMPERATURES FOR WEDNESDAY AND THURSDAY...MAINLY OVER THE PANHANDLE. MOISTURE DOES TRY TO RETURN TO THE EAST PART OF THE CWA THURSDAY AFTERNOON AND HAVE KEPT SOME POPS IN THAT AREA. OTHERWISE...WEDNESDAY THROUGH THURSDAY MORNING SHOULD SEE A MINIMUM OF LATE DAY THUNDERSTORM ACTIVITY. WESTERLY SURFACE WINDS WILL GUST AS HIGH AS 45 MPH ALONG AND WEST OF THE LARAMIE RANGE ON WEDNESDAY. LONG TERM...THURSDAY NIGHT THROUGH TUESDAY LATEST WATER VAPOR LOOP WAS SHOWING THE NEXT POTENTIAL VORTICITY ANOMALY MOVING THROUGH BRITISH COLUMBIA. THIS FEATURE IS EXPECTED TO ROTATE THROUGH NORTHERN MONTANA FRIDAY NIGHT INTO SATURDAY. THIS FEATURE WILL NOT HAVE MUCH IN THE WAY OF MOISTURE TO WORK WITH. THEREFORE...PRECIPITATION CHANCES WILL BE QUITE NIL EXCEPT FOR THE NEBRASKA COUNTIES WHERE DEWPOINTS WILL BE A LITTLE RICHER AS THE BOUNDARY PASSES THROUGH. BEHIND THE BOUNDARY...WESTERLY FLOW WILL BE POSSIBLE WHICH WILL TEND TO DRY THINGS OUT AND ALLOW FOR WARMER TEMPERATURES. WE MAY BE DEALING WITH SOME FIRE WEATHER PROBLEMS ESPECIALLY WEST OF THE LARAMIE RANGE AFTER THAT BOUNDARY PASSES THROUGH. HOWEVER...FUELS PAGE IS STILL NOT SHOWING THE POTENTIAL FOR LARGE FIRE GROWTH. WE WILL HAVE TO SEE HOW THINGS EVOLVE DURING THE NEXT COUPLE OF DAYS. THE NEXT CONCERN WILL BE THE RETURN OF MONSOONAL FLOW LATE THIS WEEKEND INTO EARLY NEXT WEEK. THE MODELS ARE TENDING TO SHOWING THE UPPER LEVEL RIDGE GRADUALLY BUILDING OVER THE PLAINS WHILE THE UPPER LEVEL TROF DIGS IN THE NORTHWEST. THIS WILL BRING BACK OUR CHANCE OF AFTERNOON THUNDERSTORMS ACROSS PORTIONS OF THE AREA. TEMPERATURE FORECAST LOOKS TO BE IN GOOD SHAPE AT THIS POINT. AVIATION...18Z TAF ISSUANCE... VFR CONDITIONS WILL BE COMMON OVER THE CWA THROUGH THURSDAY. THERE WILL BE SHOWERS AND THUNDERSTORMS OVER THE SOUTHEAST WYOMING PART OF THE CWA THROUGH THE EVENING. THAT ACTIVITY WILL SPREAD OVER THE PANHANDLE TONIGHT. SOME OF THE STRONGER STORMS WILL PRODUCE HEAVY RAIN...FREQUENT LIGHTNING AND BRIEF WIND GUSTS TO 50 MPH. SOUTHWEST TO WEST WINDS WILL GUST AS HIGH AS 30 KNOTS THROUGH SUNSET. WESTERLY SURFACE WINDS WILL GUST AS HIGH AS 40 KNOTS IN AREAS ALONG AND WEST OF THE LARAMIE RANGE ON WEDNESDAY. FIRE WEATHER... VERY WARM...BREEZY AND DRY CONDITIONS WILL CONTINUE OVER THE WYOMING PART OF THE CWA THROUGH SUNSET. THERE WILL ALSO BE SOME SHOWERS AND THUNDERSTORMS OVER THE CWA TONIGHT. SOME OF THE STORMS WILL PRODUCE WIND GUSTS TO 50 MPH AND FREQUENT LIGHTNING...BUT ALSO A WETTING RAINFALL. A COLD FRONT WILL MOVE ACROSS THE CWA LATE TONIGHT AND WEDNESDAY MORNING. BEHIND THE FRONT WILL BE DRIER AIR AND WESTERLY SURFACE WINDS WITH GUSTS TO 45 MPH...ESPECIALLY IN SOUTHEAST WYOMING. THE PLUME OF MONSOONAL MOISTURE WILL ALSO BE PUSHED SOUTH AND EAST OF THE CWA THROUGH AT LEAST THURSDAY MORNING. THE PLUME THEN MOVES BACK OVER THE SOUTHEAST QUARTER OF THE CWA FOR THURSDAY AFTERNOON THROUGH FRIDAY. THE RESULT WILL BE A MINIMUM OF THUNDERSTORM ACTIVITY OVER MOST OF THE CWA WEDNESDAY THROUGH THURSDAY MORNING. TEMPERATURES WILL ALSO BE A BIT COOLER BEHIND THE COLD FRONT FOR WEDNESDAY AND THURSDAY...ESPECIALLY OVER THE PANHANDLE. && .CYS WATCHES/WARNINGS/ADVISORIES... WY...NONE.
