Area forecast discussion, Sep 4, 10:56 AM MST, 4 hours 19 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE CHEYENNE WY 1156 AM MDT WED SEP 4 2013 .SHORT TERM...(TODAY THROUGH THURSDAY) ISSUED AT 402 AM MDT WED SEP 4 2013 STRONG UPPER LEVEL HIGH PRESSURE WILL REMAIN OVER THE ROCKIES TODAY AND TOMORROW WITH GENERALLY WEAK FLOW ALOFT. SOME WEAK ENERGY EMBEDDED IN THE ANTICYCLONIC FLOW WILL MOVE UP FROM WEST CENTRAL COLORADO TODAY AND WILL ADVECT IN MID AND UPPER LEVEL MOISTURE TO THE CWA. AT THE SURFACE...HOT TEMPS IN THE MID 80S TO MID 90S ALONG WITH THE WEAK UPPER ENERGY WILL INDUCE PRESSURE FALLS OVER THE MOUNTAINS AND IMMEDIATE ADJACENT PLAINS. THIS SFC TROUGH WILL MOVE SLOWLY EASTWARD BECOMING A LEESIDE PRESSURE TROUGH THROUGH THE DAY. AS A RESULT...SOUTHEASTERLY SFC FLOW WILL SET UP ACROSS THE EASTERN PLAINS WHILE SOUTHWEST WINDS WILL PREVAIL WEST OF THE LARAMIE RANGE. LOOKING AT A CONVERGENCE BOUNDARY SETTING UP ALONG THE LARAMIE RANGE IN THIS FLOW PATTERN...WITH DEW POINTS PROGGED TO REMAIN STEADY IN THE MID TO UPPER 50S. CAPE VALUES LOOK TO INCREASE TO VALUES RANGING BETWEEN 500 AND 1000 J/KG BY THE LATE AFTERNOON AND SUFFICIENT SFC HEATING WILL DIMINISH INHIBITION THROUGH THIS TIME. WITH THIS SAID...WILL SEE CONVECTION DEVELOP OVER THE MOUNTAINS IN THE LATE MORNING AS THE UPPER WAVE APPROACHES AND SFC HEATING STRENGTHENS...ESPECIALLY OVER THE LARAMIE RANGE WHERE THE CONVERGENCE BOUNDARY WILL PROVIDE ADDITIONAL FORCING. STORM MOTIONS WILL BE RATHER SLOW WITH ONLY 10 TO 15 KTS OR SO OF FLOW PROGGED WITHIN THE CLOUD LAYER BASED OFF FORECAST SOUNDINGS. BULK SHEAR VALUES WILL AVERAGE BETWEEN 20 AND 30 KTS SO NOT LOOKING TO SEE A WHOLE LOT OF ORGANIZATION OF STORMS THAT DEVELOP EITHER. EVEN WITH SLOW STORM MOTIONS...STILL EXPECTING THEM TO MOVE INTO THE EASTERN PLAINS WITH REDEVELOPMENT LIKELY DUE TO PLENTIFUL BOUNDARY INTERACTION WITH THE GENERAL DISORGANIZATION OF STORMS. THINKING CONVECTION WILL BECOME RATHER DEEP IN MOST AREAS WITH THE MARGINAL INSTABILITY IN PLACE SO COULD SEE SOME MAINLY SMALL HAIL AND STRONG DOWNDRAFT WINDS OUT OF THIS DEVELOPMENT...ALONG WITH HEAVY RAIN AS PWATS WILL BE BETWEEN 1 AND 1.25 INCHES OVER THE EASTERN PLAINS BY THE LATE AFTERNOON. RIGHT NOW...LOOKING AT A SCATTERED COVERAGE OF CONVECTION...BUT COULD BE MORE WIDESPREAD DEPENDING ON JUST HOW UNSTABLE THE ENVIRONMENT BECOMES IN THE LATE AFTERNOON. MODELS SHOW RESIDUAL INSTABILITY OVER EAST CENTRAL WYOMING AND THE NORTHERN NEBRASKA PANHANDLE THROUGH THE EVENING WHERE SOUTHEASTERLY FLOW REMAINS STRONGER. A SOUTHERLY LLVL JET WILL DEVELOP IN THE LATE EVENING AS WELL AND WILL MAINTAIN CHANCES FOR ELEVATED TSTORMS THROUGH AT LEAST MIDNIGHT HERE. COULD SPILL OVER TO THE EARLY MORNING HOURS OF THURSDAY...BUT WITH ONLY 15 TO 20 KTS OF 700 MB FLOW EXPECTED HERE PROBABLY WILL NOT BE VERY ACTIVE SETUP. WILL HAVE TO WATCH FOR LOW STRATUS AND FOG DEVELOPMENT IN THIS AREA OF MOIST SOUTHEASTERLY FLOW...BUT MODELS ARE NOT SHOWING A VERY STRONG SIGNAL AT THIS TIME. THE UPPER LEVEL RIDGE AXIS WILL MOVE OVERHEAD ON THURSDAY AND WILL SHIFT THE LEESIDE PRESSURE TROUGH A LITTLE FURTHER EAST FROM TODAY. THIS WILL ALLOW A SOMEWHAT DRIER AIRMASS TO FILTER INTO THE REGION BOTH AT THE SFC AND ALOFT. THE HIGHER INSTABILITY WILL BE SITUATED FURTHER EAST AS A RESULT...ALTHOUGH MODELS DO SHOW POCKETS OF HIGHER CAPE OVER THE PANHANDLE IN THE LATE AFTERNOON. AS IT STANDS...THURSDAY WILL BE QUITE SIMILAR TO WEDNESDAY WITH SLIGHTLY LESS COVERAGE AND INTENSITY DUE TO LOWER OVERALL MOISTURE AVAILABILITY. .LONG TERM...(THURSDAY NIGHT THROUGH TUESDAY) ISSUED AT 402 AM MDT WED SEP 4 2013 MAY FINALLY SEE AN END TO THE HOT TEMPERATURES AS A PATTERN CHANGE LOOKS TO BE TAKING SHAPE IN THE EXTENDED. UPPER HIGH PRESSURE FORECAST TO BEGIN MOVING EAST FRIDAY. BY FRIDAY AFTERNOON...IT IS FORECAST TO BE CENTERED OVER WESTERN KANSAS AND THEN CENTRAL KANSAS BY SATURDAY AFTERNOON. 700MB TEMPERATURES STILL WARM...+16C ON FRIDAY...BUT STARTING TO COOL. BY SATURDAY AFTERNOON...THEY LOOK TO BE DOWN TO +14C. FRIDAY AND SATURDAY SHOULD SEE HIGHS IN THE MID 90S IN THE PANHANDLE WITH MID TO UPPER 80S IN SOUTHEAST WYOMING. SUNDAY INTO MONDAY...GOOD AGREEMENT BETWEEN THE GFS AND ECMWF ON A PACIFIC LOW PRESSURE SYSTEM TRACKING INTO WESTERN MONTANA. MONSOONAL MOISTURE GETS PULLED INTO WESTERN WYOMING AS THIS TAKES PLACE. ASSOCIATED COLD FRONT WITH THE LOW LOOKS TO MOVE INTO THE AREA MONDAY MORNING AND THROUGH THE PANHANDLE MONDAY EVENING. SHOULD BE A DECENT DAY FOR PRECIP AS THIS HAPPENS AND MOST LOCATIONS SHOULD SEE SOME MUCH NEEDED RAINFALL AS THE MONSOONAL MOISTURE MOVES EAST AHEAD OF THE SYSTEM. COULD BE QUITE WINDY OUT IN THE PANHANDLE AHEAD OF THIS FRONT. GFS SHOWING 850MB WINDS OUT THERE AT 40 TO 45KTS JUST AHEAD OF THE FRONT. 700MB TEMPERATURES REALLY BEGIN TO COOL BEHIND THE FRONT ON TUESDAY. BY TUESDAY AFTERNOON...WE ARE LOOKING AT +6 TO +8C TEMPERATURES AT 700MB. SHOULD SEE HIGHS IN THE 70S ACROSS SOUTHEAST WYOMING WITH LOW 80S IN THE PANHANDLE. && .AVIATION...(FOR THE 18Z TAFS THROUGH 18Z THURSDAY MORNING) ISSUED AT 1139 AM MDT WED SEP 4 2013 VFR CONDITIONS THROUGH THE TAF PERIOD. GOOD MOISTURE REMAINS OVER THE AREA TODAY SO SCATTERED STORMS ARE EXPECTED TO DEVELOP IN THE MTNS OF SOUTHEAST WY BY EARLY AFTERNOON THEN SPREAD EASTWARD ACROSS THE PLAINS BY LATE AFTERNOON INTO THE EVENING. SOME OF THE STORMS COULD PRODUCE BRIEF HEAVY RAIN AND GUSTY WINDS. THE TSTMS WILL LINGER OVER THE NEBRASKA PANHANDLE THROUGH AROUND 05Z. WINDS WILL GENERALLY REMAIN BELOW 10 KTS OUTSIDE OF GUSTY OUTFLOW WINDS. && .FIRE WEATHER... ISSUED AT 402 AM MDT WED SEP 4 2013 WELL ABOVE NORMAL TEMPERATURES AND RELATIVELY MOIST CONDITIONS WILL OCCUR OVER THE DISTRICT TODAY. A WEAK UPPER LEVEL DISTURBANCE WILL MOVE OVERHEAD AS WELL...BRINGING A GOOD CHANCE FOR SCATTERED SHOWERS AND THUNDERSTORMS. THIS ACTIVITY WILL INITIATE OVER THE MOUNTAINS LATE THIS MORNING AND WILL MOVE OFF INTO THE EASTERN PLAINS THROUGH THE LATE AFTERNOON AND EVENING. MODERATE TO HEAVY RAIN...SMALL HAIL AND GUSTY DOWNDRAFT WINDS ARE ALL POSSIBLE WITH THIS ACTIVITY. THURSDAY WILL SEE SIMILAR CONDITIONS...ALTHOUGH SLIGHTLY LESS THUNDERSTORM ACTIVITY AS DRIER AIR BEGINS TO FILTER IN FROM THE WEST. MINIMUM HUMIDITIES WILL REMAIN AROUND 20 PERCENT OR HIGHER THE NEXT COUPLE OF DAYS AND WINDS OUTSIDE OF THUNDERSTORMS WILL STAY RELATIVELY LIGHT. HOT CONDITIONS AND CHANCES FOR AFTERNOON SHOWERS AND THUNDERSTORMS WILL CONTINUE THROUGH THE WEEKEND. && .CYS WATCHES/WARNINGS/ADVISORIES... WY...NONE.
