AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE CHEYENNE WY 117 PM MDT TUE AUG 5 2014 .SHORT TERM...(THIS AFTERNOON THROUGH WEDNESDAY NIGHT) ISSUED AT 230 PM MDT TUE AUG 5 2014 WATER VAPOR IMAGERY STILL SHOWING MONSOONAL MOISTURE OVER THE STATE OF WYOMING THIS AFTERNOON...BUT A LARGE DRY SLOT CONTINUES TO EDGE NORTHEAST FROM UTAH AND SOUTHWESTERN COLORADO. PLUME OF DEEPEST MOISTURE IS NOW OFF TO OUR EAST IN CENTRAL NEBRASKA AND SOUTH DAKOTA. AT THE SURFACE...THE FRONTAL BOUNDARY THAT MOVED INTO THE AREA LAST NIGHT AND THIS MORNING IS LAYING UP AGAINST THE LARAMIE RANGE AND IS THE FOCUS FOR SHOWERS AND THUNDERSTORM DEVELOPMENT. MOSAIC RADAR SHOWS CONVECTION CONCENTRATED EAST OF THE LARAMIE RANGE AND ACROSS THE SOUTHERN PANHANDLE SO FAR TODAY. WIDELY SCATTERED SHOWERS AND THUNDERSTORMS ACROSS SOUTHWESTERN WYOMING AND NORTHWESTERN COLORADO CONTINUE TO MOVE NORTHEAST. SOME OF THIS ACTIVITY WILL MAKE ITS WAY INTO CARBON AND ALBANY COUNTIES THIS AFTERNOON IF IT HOLDS TOGETHER. MINOR WAVE SEEN ON WATER VAPOR IMAGERY WILL TRACK FROM SOUTHWEST WYOMING THROUGH CENTRAL WYOMING AND THEN EAST IN SOUTH DAKOTA THROUGH THE AFTERNOON. THIS SHOULD AID IN INCREASING PRECIP COVERAGE. LATEST HRRR FORECAST SHOWS BANDS OF SHOWERS/TSTMS DEVELOPING OVER THE LARAMIE RANGE...THEN MOVING EAST NORTHEAST INTO THE PANHANDLE THIS AFTERNOON. COULD SEE A MARGINALLY SEVERE THUNDERSTORM EVENT ACROSS THE NORTHERN PANHANDLE TODAY WITH SBCAPES AROUND 1200-1400 J/KG AROUND ALLIANCE AND CHADRON. THEY ARE STILL CAPPED PRETTY GOOD THOUGH SO FAR. NAM SOUNDINGS SHOWING THIS CAP BREAKING AROUND 21Z OR SO AND HRRR SHOWING A PRETTY STRONG CELL DEVELOPING SOUTH OF MONTROSE IN SIOUX COUNTY OUT IN THE NORTHERN PANHANDLE BY LATE AFTERNOON. WITH THE SHORTWAVE MOVING THROUGH THE AREA THIS EVENING...THE FRONTAL SYSTEM BEGINS TO BE LIFTED NORTHEAST. SHOWERS AND THUNDERSTORMS SHOULD DECREASE IN COVERAGE ACROSS EXTREME SOUTHEAST WYOMING AND THE SOUTHERN PANHANDLE THIS EVENING. SHOWERS AND THUNDERSTORMS RETURN WEDNESDAY AFTERNOON WITH THE ECMWF AND NAM/WRF MODELS IN GOOD AGREEMENT. BEST AREA FOR CONVECTION LOOKS TO BE EAST OF THE LARAMIE RANGE AND THE PANHANDLE BY MID AFTERNOON PERSISTING INTO MID EVENING BEFORE TAPERING OFF WITH LOSS OF DAYTIME HEATING. .LONG TERM...(THURSDAY THROUGH TUESDAY) ISSUED AT 1159 AM MDT TUE AUG 5 2014 THURSDAY...EVEN THOUGH RIDGING ALOFT WILL LIMIT AREAL THUNDERSTORM COVERAGE...LOOKS LIKE ENOUGH LOW AND MID LEVEL MOISTURE FOR LATE DAY ISOLATED TO SCATTERED THUNDERSTORMS...MOST NUMEROUS FROM SIDNEY TO CHADRON WHERE UPWARD VERTICAL MOTION WILL BE MOST PRONOUNCED. FRIDAY...INCREASE IN LOW AND MID LEVEL MOISTURE ALONG WITH A WELL PRONOUNCED LOW AND MID LEVEL THETA-E RIDGE AXIS WILL AID IN AT LEAST SCATTERED AFTERNOON THUNDERSTORMS EAST OF INTERSTATE 25. SATURDAY...AS THE ATMOSPHERE DRIES SOMEWHAT FROM FRIDAY...WE EXPECT A CORRESPONDING DECREASE INT THE AREAL THUNDERSTORM COVERAGE. BEST CHANCES FOR STORMS WILL BE ALONG WESTERN NEBRASKA WHERE A LOW LEVEL CONVERGENCE AXIS IS PROGGED TO DEVELOP. SUNDAY/TUESDAY...ISOLATED LATE DAY THUNDERSTORMS WILL OCCUR WITH ADEQUATE LOW AND MID LEVEL MOISTURE AND WEAK LOW LEVEL UPSLOPE EAST WINDS. MONDAY...MINIMAL THUNDERSTORM CHANCES WITH RIDGING ALOFT AND LIMITED LOW AND MID LEVEL MOISTURE. && .AVIATION...(FOR THE 18Z TAFS THROUGH 18Z WEDNESDAY MORNING) ISSUED AT 1047 AM MDT TUE AUG 5 2014 USED LATEST HRRR MODEL RUN TO DETERMINE PRECIP LOCATION AND TIMING FOR OUR SOUTHEAST WYOMING AND NEBRASKA PANHANDLE TAFS THIS AFTERNOON. THIS MODEL HAS BEEN DOING VERY WELL ON CONVECTIVE INITIATION AND TIMING. IFR STRATUS TO RETURN LATE TONIGHT FOR THE NORTHERN PANHANDLE AS WELL. && .FIRE WEATHER... ISSUED AT 230 PM MDT TUE AUG 5 2014 MONSOONAL MOISTURE FROM THE SOUTHWEST WILL CONTINUE TO BRING THE AREA CHANCES FOR SHOWERS AND THUNDERSTORMS THROUGH THE WEEK.

EXPECT FAIR OVERNIGHT RECOVERIES IN HUMIDITY WEST OF THE LARAMIE RANGE WITH EXCELLENT RECOVERIES EAST. DECREASING COVERAGE OF SHOWERS AND THUNDERSTORMS FROM TODAY ON FOR THE MOST PART AS MONSOONAL MOISTURE GETS SHUNTED SOUTH AND EAST. WINDS TO REMAIN LIGHT THROUGH THE WEEK AS WELL...KEEPING ELEVATED FIRE WEATHER CONDITIONS IN CHECK. && .CYS WATCHES/WARNINGS/ADVISORIES... WY...NONE.
