Area forecast discussion, Aug 25, 3:04 PM MST, 1 hour 56 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE CHEYENNE WY 404 PM MDT MON AUG 25 2014 .SHORT TERM...(THIS EVENING THROUGH TUESDAY) ISSUED AT 404 PM MDT MON AUG 25 2014 VIGOROUS CONVECTION HAS DEVELOPED OVER THE SNOWY AND SIERRA MADRE MOUNTAINS EARLY THIS AFTERNOON AHEAD OF A SHORTWAVE FEATURE MOVING UP FROM SOUTHWESTERN CO. THE ENVIRONMENT HERE IS RELATIVELY UNSTABLE WITH 500 TO 1000 J/KG OF SBCAPE ANALYZED ON MESOANALYSIS...WITH LLVL LAPSE RATES OF 7 TO 8 C/KM. AS THE STORM NEAR LARAMIE EARLIER ALREADY PRODUCE SMALL TO SEVERE SIZE HAIL...WOULD EXPECT ONE OR TWO MORE STORMS TO ORGANIZE LIKE THIS THROUGH THE LATE AFTERNOON...WITH THE MAJORITY OF STORMS PRODUCING MODERATE TO HEAVY RAIN...SMALL HAIL...AND GUSTY WINDS THROUGH THE EVENING. FURTHER EAST ACROSS THE PLAINS...EAST-SOUTHEASTERLY UPSLOPE FLOW IS STRENGTHENING AHEAD OF THE UPPER WAVE WAVE...ALTHOUGH INSTABILITY PARAMETERS ARE NOT TOO IMPRESSIVE. SO WOULD EXPECT THE CONVECTION COMING OFF THE MOUNTAINS LATE THIS AFT AND EVENING TO NOT BE AS VIGOROUS OVER THE PLAINS. STILL CANNOT RULE OUT GUSTY WINDS AND SMALL HAIL AS THE APPROACHING SHORTWAVE WILL HELP GENERATE STRONG UPDRAFTS AT TIMES THRU THIS EVENING. SHOULD SEE A BREAK IN THE ACTIVITY LATE TONIGHT WITH ANOTHER ROUND OF SHOWERS AND T-STORMS DEVELOPING IN THE LATE MORNING AND AFTERNOON TOMORROW AHEAD OF A STRONGER WAVE EJECTING OUT AHEAD OF THE MAIN LOW SITUATED OVER NV/UT. PERSISTENT SOUTHEASTERLY FLOW OVER THE PLAINS WILL CONTINUE TO ADVECT IN HIGHER DEW POINTS THROUGH THE DAY...WITH SBCAPE VALUES INCREASING TO BETWEEN 500 AND 1500 J/KG THROUGH THE DAY. SHEAR WILL BE LESS THO...AND WILL AVERAGE AROUND 30 KTS ACROSS THE CWA. SO THERE WILL ONCE AGAIN BE POTENTIAL FOR STRONG STORMS...ESPECIALLY IN THE EAST WITHIN THE RELATIVELY UNSTABLE ENVIRONMENT WHERE A WEAK CAP IS IN PLACE...BUT LIKELY WILL SEE LESS ORGANIZATION AND MORE VERTICAL UPDRAFTS WHICH WILL LEND TO MORE A HEAVY RAIN AND SMALL HAIL TO MARGINAL SEVERE HAIL THREAT. THE MAIN UPPER LOW WILL MOVE INTO WESTERN COLORADO ON WEDNESDAY...WITH MODELS INDICATING A GOOD DOSE OF MID LEVEL ENERGY AND LOW-MID LEVEL CONVERGENCE SUPPORTING WIDESPREAD LIFT ACROSS THE CWA. SO WILL MAINTAIN THE TREND UPWARD FOR POPS ACROSS THE AREA FOR WEDNESDAY. NOT A WHOLE LOT OF INSTABILITY IS PROGGED DURING THIS TIME...SO LIKELY TO BE A STEADY MODERATE RAINFALL WITH ANY FLOODING POTENTIAL TO REMAIN LOCAL. TEMPERATURES WILL REMAIN BELOW NORMAL THROUGH WEDNESDAY. .LONG TERM...(TUESDAY NIGHT THROUGH MONDAY) ISSUED AT 404 PM MDT MON AUG 25 2014 WEDNESDAY NIGHT...SLOW MOVING UPPER TROUGH SLIDES ACROSS OUR COUNTIES...WITH AT LEAST SCATTERED SHOWERS AND ISOLATED THUNDERSTORMS PREVAILING WELL INTO THE EVENING HOURS...AND SCATTERED SHOWERS AFTER MIDNIGHT. THURSDAY...SHORTWAVE TROUGH MOVES SLOWLY INTO WESTERN NEBRASKA AND WESTERN KANSAS WITH A MORE STABLE AIRMASS MOVING IN ACROSS OUR COUNTIES AND ONLY SOME LEFTOVER SHOWERS AND THUNDERSTORMS IN THE AFTERNOON FROM CHADRON TO KIMBALL TO CHEYENNE AND LARAMIE. FRIDAY...LOW AND MID LEVELS DRY OUT AS RIDGING ALOFT DEVELOPS OVERHEAD...THUS A DRY AND WARMER DAY ON TAP. SATURDAY...THE DRY AND WARMER TEMPERATURES CONTINUE INTO LABOR DAY WEEKEND AS FASTER SOUTHWEST FLOW ALOFT MOVES OVER MONTANA...INDUCING SURFACE LEE TROUGHING OVER THE EASTERN SLOPES OF THE ROCKIES...AND FURTHER DRYING OUT OUR LOW LEVELS. SUNDAY...SOUTHWEST FLOW ALOFT STRENGTHENS AND WE MAY SEE ISOLATED LATE DAY SHOWERS AND THUNDERSTORMS WITH A SLIGHT INCREASE IN LOW AND MID LEVEL MOISTURE. MONDAY...LOW AMPLITUDE SHORTWAVE TROUGH ALOFT MOVES ACROSS MONTANA AND WYOMING...SENDING A COLD FRONT INTO OUR NORTHERN COUNTIES IN THE AFTERNOON...AND WITH ADEQUATE LOW AND MID LEVEL MOISTURE...WE EXPECT ISOLATED LATE DAY SHOWERS AND THUNDERSTORMS. && .AVIATION...(FOR THE 00Z TAFS THROUGH 00Z TUESDAY AFTERNOON) ISSUED AT 404 PM MDT MON AUG 25 2014 VFR PREVAILS.

ISSUED AT 404 PM MDT MON AUG 25 2014 A SERIES OF WEATHER SYSTEMS WILL BRING ISOLATED TO SCATTERED SHOWERS AND THUNDERSTORMS TO THE DISTRICT TODAY THROUGH WEDNESDAY. THE BEST CHANCE FOR WETTING RAINS WILL BE DURING THE AFTERNOON AND EVENING HOURS...ALTHOUGH THE POSSIBILITY DOES EXIST FOR SHOWERS TO CONTINUE THROUGH THE OVERNIGHT PERIOD.
