NWS Cheyenne, WY wrote its last area forecast discussion before the first event at May 23, 9:49 PM MST, 3 hours 33 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE CHEYENNE WY 1049 PM MDT THU MAY 23 2013 .UPDATE... ISSUED AT 745 PM MDT THU MAY 23 2013 THE FEW SHOWERS OVER THE WEST PART OF THE CWA HAVE ENDED AS OF 0030Z. MAIN ISSUES FOR THE REST OF TONIGHT WILL CONTINUE TO BE THE STRONG WINDS OVER MUCH OF THE CWA AS WELL AS THE POSSIBILITY OF FOG AND DRIZZLE. SOUTHERLY WINDS HAVE BEEN GUSTING AS HIGH AS 55 MPH FROM KLAR TO KDGW. THE TIGHT SURFACE PRESSURE GRADIENT SHOULD GRADUALLY SHIFT EAST TONIGHT. THAT SHOULD ALLOW FOR THE WINDS TO SLOWLY TAPER OFF IN THE WEST AND INCREASE OVER AND NEAR THE PANHANDLE. THE PREVIOUSLY ISSUED WIND ADVISORY STARTING SOON AND RUNNING THROUGH 12Z OVER THE PANHANDLE LOOKS GOOD. CLOUD BASES SHOULD LOWER OVER THE EAST PART OF THE CWA TONIGHT. FOG WILL LIKELY BE KEPT TO A MINIMUM DUE TO THE TIGHT SOUTHERLY SURFACE PRESSURE GRADIENT. THE SAME CAN BE SAID FOR DRIZZLE AS THERE IS LESS OF A CLOUD DEPTH THAN WEDNESDAY NIGHT. FOG HAS BEEN DEVELOPING EARLY THIS EVENING OVER THE SOUTHERN LARAMIE RANGE. THE FOG MAY BE DENSE AT TIMES EARLY TONIGHT BEFORE THE WINDS TURN MORE SOUTHWESTERLY. IN A RECENT UPDATE REMOVED THE MENTION OF SHOWERS AND MADE MINOR ADJUSTMENTS TO THE FIRST PERIOD OF THE FORECAST. && .SHORT TERM...(THIS EVENING THROUGH SATURDAY NIGHT) ISSUED AT 300 PM MDT THU MAY 23 2013 FOG TOOK MUCH OF THE DAY TO ERODE ALONG THE SOUTHERN LARAMIE RANGE BUT MOST OF IT IS FINALLY GONE. AT THIS TIME THE SUMMIT WEBCAM SHOWING SOME LINGERING FOG BUT IT IS NO LONGER DENSE AND IS EXPECTED TO MIX OUT COMPLETELY OVER THE NEXT FEW HOURS. THE QUESTION IS IF...OR MAYBE WHEN WILL THE FOG SET BACK IN. MODELS DO SHOW MOISTURE HUGGING THE LARAMIE RANGE THROUGH MUCH OF TONIGHT ALTHOUGH THE UPSLOPE FLOW WILL WEAKEN THROUGH THE NIGHT AS THE LOW LEVEL JET SLIDE EAST INTO THE NEBRASKA PANHANDLE. WINDS SHOULD TURN TO THE SOUTHWEST AROUND SUNRISE WITH DRY AIR QUICKLY ERODING ANY LOW CLOUDS AND FOG. MAINLY LOOKING AT LOW STRATUS EAST OF THE LARAMIE RANGE BUT SOME PATCHY FOG POSSIBLE TONIGHT. LARGE TEMPERATURE AND PRESSURE DIFFERENCE CURRENTLY DRIVING WINDS ACROSS CONVERSE COUNTY AND ALBANY COUNTIES. SUSTAINED WINDS OF 40 MPH WITH GUSTS OVER 50 MPH OCCURRING AT LARAMIE AND DOUGLAS. THESE WINDS WILL CONTINUE THROUGH THE AFTERNOON INTO POSSIBLY INTO EARLY EVENING AS THE STRONG GRADIENT RELAXES AND THE MAIN CORE OF THE LOW LEVEL JET SHIFTS EAST. WILL BE CLOSE TO HIGH WIND WARNING CRITERIA UNTIL WINDS DO RELAX. THE OTHER WIND CONCERN IS OVER THE NEBRASKA PANHANDLE TONIGHT. MODELS SHOWING 50 TO 60 KT WINDS BELOW A STRONG LOW LEVEL INVERSION. STRONGEST WINDS WILL BE OVER NORTHERN PORTIONS OF THE PANHANDLE WHERE 50 MPH WIND GUSTS SHOULD REACH THE SURFACE. MAIN CONCERN IS WITH SUCH STRONG WINDS BELOW THE INVERSION THAT THESE WINDS COULD BE DIRECTED TO THE SURFACE. SHOULD THIS OCCUR...A HIGH WIND WARNING WOULD BE NEEDED AND MAY NEED TO ADD AN ADVISORY TO SOUTHERN PORTIONS OF THE PANHANDLE. TURNING TO FRIDAY...SKIES WILL CLEAR FROM WEST TO EAST THROUGH THE DAY WITH MUCH WARMER TEMPERATURES ACROSS THE FORECAST AREA. WILL SEE SOME 80S OVER EASTERN PORTIONS OF THE AREA...ALTHOUGH IT DEPENDS HOW FAST THE CLEARING OCCURS OVER THE PANHANDLE. THERE IS A CHANCE FOR THUNDERSTORMS IN THE PANHANDLE FRIDAY AFTERNOON. NOT THE BEST SET UP BUT COULD SEE THUNDERSTORMS DEVELOP ALONG A SURFACE MOISTURE DISCONTINUITY. MODELS STILL SHOWING 2000 PLUS J/KG SURFACE BASED CAPE AND THE NAM AND GFS BOTH MODEL SOUNDING NOW SHOWING THE CAP BREAKING...WHICH IS DIFFERENT FROM PREVIOUS RUN. MODEL SOUNDINGS SHOWING 0-6 KM BULK SHEAR VALUES 40-50 KTS... SUPPORTIVE OF SUPERCELL THUNDERSTORMS CAPABLE OF PRODUCING LARGE HAIL. WITH A BOUNDARY IN PLACE ISOLATED TORNADOES NOT OUT OF THE QUESTION. STILL LOOKING LIKE THE MOISTURE BOUNDARY WILL RETREAT TO THE WEST...SIMILAR TO A RETREATING DRY LINE LIKE OCCUR IN WEST TEXAS THIS TIME OF YEAR. ALTHOUGH THE CAP WILL STRENGTHEN DURING THE EVENING HOURS...THUNDERSTORM COULD ACTUALLY DEVELOP WESTWARD FRIDAY EVENING. NOT LIKELY...BUT SOMETHING TO WATCH. ANOTHER CHANCE FOR THUNDERSTORMS SATURDAY AFTERNOON IN THE NEBRASKA PANHANDLE. .LONG TERM...(SUNDAY THROUGH THURSDAY) ISSUED AT 300 PM MDT THU MAY 23 2013 UPPER TROF WILL HOLD OVER THE PACIFIC NW SUNDAY THROUGH TUESDAY KEEPING THE CWA UNDER A GENERALLY SW FLOW ALOFT. WEAK IMPULSES EMANATING FROM THE BASE OF THIS TROF WILL MOVE ACROSS THE CWA AND LIKELY HELP TO SET OFF SOME AFTERNOON AND EVENING CONVECTION MAINLY OVER THE PLAINS. SUNDAY LOOKING MAINLY DRY FOR NOW THEN SOME UPTICK MONDAY AND TUESDAY. UPPER TROF WILL THEN MOVE EAST AND ACROSS THE REGION WEDNESDAY. GFS BRINGS IT MORE BODILY ACROSS THE REGION AND MORE QPF WHILE ECMWF SPLITS THE ENERGY...CUTTING OFF AN UPPER LOW OVER NORTHERN MEXICO THUS HAVING LESS QPF OVER THE CWA. EITHER WAY AT LEAST WIDELY SCATTERED SHOWERS AND A FEW STORMS LOOK A DECENT BET WEDNESDAY BEFORE DRYING ON THURSDAY. TEMPERATURES WARM THROUGH THE WEEKEND INTO MONDAY THEN TRENDING DOWN A BIT TUESDAY AND WEDS. && .AVIATION...(FOR THE 06Z TAFS THROUGH 06Z FRIDAY EVENING) ISSUED AT 1043 PM MDT THU MAY 23 2013 THROUGH 15Z...WIDESPREAD MVFR AND IFR IN FOG AND LOW CLOUDS ALONG AND EAST OF INTERSTATE 25...THEN BECOMING VFR. VFR ELSEWHERE. AFTER 21Z...ISOLATED TO SCATTERED THUNDERSTORMS DEVELOPING ACROSS THE SOUTHERN NEBRASKA PANHANDLE PRODUCING GUSTY AND ERRATIC WINDS AND LOCALIZED SEVERE TURBULENCE. && .FIRE WEATHER... ISSUED AT 300 PM MDT THU MAY 23 2013 CONDITIONS WILL VARY ACROSS THE FORECAST AREA THE NEXT FEW DAY WITH MOSTLY DRY AND BREEZY CONDITIONS WEST WITH LESS WIND EAST AND HIGHER CHANCES FOR THUNDERSTORMS. HUMIDITY VALUES WILL DROP BELOW 20 PERCENT IN THE AFTERNOON THROUGH THIS WEEKEND FOR LOWER ELEVATIONS WEST OF THE LARAMIE RANGE AND AS LOW AS 10 PERCENT IN THE RAWLINS AREA. THERE WILL BE SMALL CHANCES FOR AFTERNOON THUNDERSTORMS MAINLY OVER THE NEBRASKA PANHANDLE THROUGH THE WEEKEND. && .CYS WATCHES/WARNINGS/ADVISORIES... WY...NONE.
