NWS Cheyenne, WY wrote its last area forecast discussion before the first event at Aug 26, 3:11 PM MST, 1 hour 34 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE CHEYENNE WY 411 PM MDT TUE AUG 26 2014 .SHORT TERM...(THIS EVENING THROUGH THURSDAY) ISSUED AT 410 PM MDT TUE AUG 26 2014 A RELATIVELY THICK CIRRUS SHIELD CONTINUES TO MOVE OVER THE CWA IN SOUTHWEST FLOW EARLY THIS AFTERNOON AHEAD OF THE STRONG UPPER LOW CURRENTLY OVER EASTERN NEVADA. THE CIRRUS HAS MINIMIZED CONVECTION OVER THE CWA SO FAR TODAY...HOWEVER THERE APPEARS TO BE SOME THINNING OF THE CLOUDS OVER THE LAST TWO HOURS OR SO BASED OFF A LOOP OF VIS IMAGERY. A WEAK PIECE OF ENERGY MOVING UP FROM THE SOUTHWEST THIS AFTERNOON IS SPARKING OFF STORMS OVER THE MOUNTAINS OF COLORADO...AND WILL INITIATE STORMS OVER THE SOUTHEAST WYOMING MOUNTAINS AS WELL OVER THE NEXT FEW HOURS. IN ADDITION...A SFC LOW CONTINUES TO DEEPEN ALONG THE LEE OF THE LARAMIE RANGE WITH SFC WINDS SHIFTING IN RESPONSE TO THE DEVELOPING LOW. INCREASING LLVL CONVERGENCE ALONG THE LARAMIE RANGE AND ADJACENT PLAINS IN THE VCTY OF THE LOW WILL ACT AS AN ADDITIONAL INITIATION POINT...AND WITH THE ENVIRONMENT EXPECTED TO BECOME INCREASINGLY UNSTABLE IN THIS AREA WITHIN LVL MOISTURE ADVECTION AND AS CIRRUS DECREASES IN COVERAGE...WILL SEE SHOWERS AND T-STORMS DEVELOP ACROSS THE PLAINS THROUGH THE EVENING. MESOANALYSIS DATA SHOWS THAT SBCAPES HAVE INCREASED TO BETWEEN 500 AND 2000 J/KG FROM WEST TO EAST ACROSS THE CWA...WITH 30 KTS OF DEEP LAYER SHEAR IN PLACE. SO...SIMILAR TO YESTERDAY...EXPECT VIGOROUS PULSE TYPE CONVECTION TO OCCUR WITH THE HIGHEST LIKELIHOOD OF PRODUCING SMALL TO LOW END SEVERE SIZE HAIL...STRONG DOWNDRAFT WINDS...AND HEAVY RAIN. THE UPPER LOW WILL STEADILY SHIFT EAST ACROSS UTAH TONIGHT WITH A STRONGER SHORTWAVE MOVING UP FROM THE SOUTHWEST AFTER MIDNIGHT IN PERSISTENT SOUTHWEST FLOW. THEREFORE...AFTER A BRIEF BREAK IN CONVECTION IN THE EARLY OVERNIGHT PERIOD...EXPECT A RESURGENCE OF DEVELOPMENT THROUGH THE EARLY MORNING HOURS FROM SOUTH TO NORTH ACROSS THE CWA. A PERIOD OF STRONG ISENTROPIC LIFT WILL OCCUR THRU THIS TIME AS WELL WITH SOME ELEVATED INSTABILITY PROGGED BY THE MODELS. MAINTAINED AT LEAST NUMEROUS SHOWERS WITH SOME EMBEDDED THUNDERSTORMS IN THE FORECAST FOR THIS SCENARIO...WITH MODERATE TO HEAVY RAIN A LIKELY BET OUT OF SOME OF THIS ACTIVITY AS NAM FORECAST SOUNDINGS SHOWING A NEARLY SATURATED PROFILE THROUGH THE MORNING. WILL HAVE TO WATCH CLOSELY FOR ANY CONVECTION THAT BECOMES STATIONARY OVER TERRAIN FEATURES OR SFC BOUNDARIES AS THE FLASH FLOOD THREAT COULD INCREASE SUBSTANTIALLY IN THESE AREAS. AT THIS POINT THO...MOSTLY DRY ANTECEDENT CONDITIONS AND THE FACT THAT THERE WILL BE SOME FLOW ALOFT PRECLUDES THE ISSUANCE OF ANY FLOOD HIGHLIGHTS AT THIS TIME. THE MAIN COLD FRONT ASSOCIATED WITH THIS SYSTEM WILL SLIDE SOUTH ACROSS THE EASTERN PLAINS WEDNESDAY AFTERNOON...SO THE THREAT FOR NUMEROUS SHOWERS AND THUNDERSTORMS WILL CONTINUE THRU THE DAY. OVERALL INSTABILITY WILL BE LESS...BUT WILL AGAIN HAVE TO KEEP A CLOSE EYE FOR HEAVY RAIN PRODUCERS AND POTENTIAL FLOODING CONCERNS AS THE FRONT ROLLS ON THROUGH. MUCH DRIER AIR AND OVERALL WEAKER FORCING WILL MOVE OVERHEAD WEDNESDAY NIGHT AND THURSDAY AS THE SYSTEM DEPARTS TO THE SOUTHWEST...WITH PERHAPS SOME LINGERING SHOWERS AND STORMS OVER SOUTHERN PORTIONS OF THE CWA ON THURSDAY IN WRAPAROUND FLOW. .LONG TERM...(THURSDAY NIGHT THROUGH TUESDAY) ISSUED AT 410 PM MDT TUE AUG 26 2014 THURSDAY NIGHT...WILL SEE ISOLATED EVENING SHOWERS AND THUNDERSTORMS SOUTH OF A RAWLINS TO SIDNEY LINE WITH THE DEPARTING SHORTWAVE TROUGH ALOFT...THEN DRY. FRIDAY...NEXT PROGRESSIVE SHORTWAVE TROUGH ALOFT SCOOTS OVER THE DAKOTAS...SENDING ITS ASSOCIATED COLD FRONT SOUTHWARD INTO OUR COUNTIES DURING THE DAYLIGHT HOURS...AND SPARKING ISOLATED TO WIDELY SCATTERED LATE DAY THUNDERSTORMS NORTH OF A RAWLINS TO ALLIANCE LINE...WITH A FEW STORMS OVER THE SNOWY AND SIERRA MADRE RANGES AS WELL...DRY ELSEWHERE. LATE DAY STORMS WILL BE MOST NUMEROUS ALONG THE FAVORED UPSLOPE LOCALES FROM DOUGLAS TO LUSK. SATURDAY...SURFACE LEE CYCLOGENESIS...LEE TROUGHING...DEVELOPS ACROSS EASTERN MONTANA AND EASTERN WYOMING AS THE SOUTHWEST FLOW ALOFT STRENGTHENS...AND WITH LIMITED LOW AND MID LEVEL MOISTURE...THUNDERSTORMS APPEAR QUITE UNLIKELY. WILL BE A BREEZY AND RELATIVELY WARM DAY FOR THE PENULTIMATE DAY OF AUGUST. SUNDAY...FOR THE LAST DAY OF AUGUST...A DECENT PACIFIC ORIGIN COLD FRONT WILL SLIDE EASTWARD ACROSS OUR COUNTIES...THOUGH WITH LIMITED LOW AND MID LEVEL MOISTURE...SHOWER AND THUNDERSTORM COVERAGE WILL BE ONLY ISOLATED TO WIDELY SCATTERED. MONDAY...LABOR DAY...AND THE FIRST DATE OF SEPTEMBER WILL HAVE AN AUTUMNAL FEEL IN THE WAKE OF THE COLD FRONT. SHOULD BE ENOUGH LOW AND MID LEVEL MOISTURE FOR ISOLATED TO WIDELY SCATTERED LATE DAY SHOWERS AND THUNDERSTORMS...AND WITH THE BRISK FLOW ALOFT...LOW LEVEL GRADIENTS WILL LIKELY BE BRISK ENOUGH FOR A BREEZY TO WINDY DAY AS WELL. TUESDAY...ANOTHER FAST MOVING LOW AMPLITUDE SHORTWAVE TROUGH ALOFT WILL MOVE ACROSS NORTHERN WYOMING AND THE DAKOTAS...SENDING A MOSTLY DRY AUTUMNAL LIKE COLD FRONT ACROSS OUR COUNTIES. && .AVIATION...(FOR THE 18Z TAFS THROUGH 18Z WEDNESDAY MORNING) ISSUED AT 1148 AM MDT TUE AUG 26 2014 THROUGH EARLY THIS EVENING...ISOLATED TO SCATTERED SHOWERS AND THUNDERSTORMS DEVELOPING...MOST NUMEROUS FROM LARAMIE TO CHEYENNE TO SIDNEY...PRODUCING LOCALIZED MVFR...TURBULENCE AND ERRATIC WIND GUSTS TO 45 MPH...OTHERWISE VFR PREVAILS.
