Cow counts a report within 15 km of the polygon while the warning was in force: a tornado for a tornado warning; hail of 1 inch or more, a gust of 58 mph or more or wind damage for a severe thunderstorm warning; a flash flood report for a flash flood warning.

Area forecast discussion, Jul 10, 5:43 PM MDT, 45 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE CHEYENNE WY 543 PM MDT WED JUL 10 2013 .UPDATE... ISSUED AT 542 PM MDT WED JUL 10 2013 THUNDERSTORMS SO FAR HAVE NOT BEEN AS WIDESPREAD OR INTENSE AS EXPECTED AS OF 2315Z. STRONGEST STORMS WERE LOCATED OVER FAR NORTHERN GOSHEN AND WEST CENTRAL SIOUX COUNTIES. POTENTIAL STILL EXISTS FOR ADDITIONAL STRONG STORMS OVER THE PANHANDLE AND NEARBY PARTS OF WYOMING THROUGH THE EVENING...WITH THE MOIST AND UNSTABLE ATMOSPHERE. IN A RECENT UPDATE HAVE INCREASED POPS OVER THE NORTHERN PANHANDLE FOR THE EVENING AND ADJUSTED POPS ELSEWHERE. && .SHORT TERM...(THIS EVENING THROUGH FRIDAY NIGHT) ISSUED AT 158 PM MDT WED JUL 10 2013 A FEW SHOWERS AND STORMS ONGOING OVER AND JUST EAST OF THE LARAMIE RANGE EARLY THIS AFTERNOON. EXPECT THIS TO GRADUALLY INCREASE THROUGH LATE THIS AFTERNOON AS IT MOVES EAST AND SOUTHEAST. EXPECT THE ACTIVITY TO CLEAR THE CWA EARLY THIS EVENING. A FEW STORMS COULD BE SEVERE WITH GOOD SHEAR AND INSTABILITY IN PLACE...ESPECIALLY OVER THE SOUTHERN PANHANDLE. DRIER AND VERY WARM/HOT CONDITIONS EXPECTED THURSDAY AS AN UPPER RIDGE MOVES ACROSS THE REGION WITH TEMPERATURES LIKELY TOPPING OUT AROUND 100 OVER PARTS OF THE PANHANDLE. ISOLATED CONVECTION NOT OUT OF THE QUESTION OVER THE PLAINS BUT WILL MAINTAIN SILENT POPS FOR NOW. THE UPPER RIDGE WILL SIFT EAST AND TILT SW-NE THURSDAY NIGHT AND FRIDAY LEAVING A MORE SWLY FLOW ALOFT OVER THE AREA. THIS WILL ADVECT SOME INCREASED MOISTURE BACK ACROSS THE CWA AND WITH ANY RIPPLES IN THE FLOW SHOULD SEE SOME INCREASE IN MAINLY LATE DAY CONVECTION FRIDAY INTO FRIDAY EVENING. TEMPERATURES A BIT COOLER FRIDAY DUE TO LOWER 700MB TEMPS BUT STILL VERY WARM OVERALL. .LONG TERM...(SATURDAY THROUGH WEDNESDAY) ISSUED AT 300 PM MDT WED JUL 10 2013 ALL MODELS SHOW THE STRONG UPPER LEVEL HIGH REMAINING OVER THE CENTRAL GREAT PLAINS THROUGH THE WEEKEND...AND LIKELY BUILDING NORTH AS WELL. THIS GENERAL PATTERN WILL ALLOW SUBTROPICAL MOISTURE TO MOVE NORTHWARD OVER THE ROCKYS AND REMAIN OVER THE AREA POSSIBLY INTO EARLY NEXT WEEK AS THE RIDGE FLATTENS A BIT. LLVL INSTABILITY AND HIGH PW/S OVER 1.00 INCH TO 1.50 INCHES WILL RESULT IN AFTERNOON/EVENING SHOWERS AND THUNDERSTORMS OVER MOST OF THE AREA BOTH SATURDAY AND SUNDAY. THUNDERSTORMS WILL DEVELOP OVER SOUTHEAST WYOMING EARLIER IN THE AFTERNOON AND THEN MOVE EASTWARD INTO WESTERN NEBRASKA LATER IN THE AFTERNOON OR IN THE EVENING. A FEW STRONG TSTORMS ARE POSSIBLE EAST OF THE LARAMIE RANGE...BUT 0-6KM SHEAR APPEARS TO BE MINIMAL ON SATURDAY...AND MAYBE MODERATE ON SUNDAY. THE GEM AND ECMWF APPEAR TO BE MORE AGGRESSIVE...SHOWING THE POSSIBILITY OF HEAVY RAIN WITH VERY SLOW STORM MOTION THIS WEEKEND. INCREASED POP BETWEEN 30 TO 60 PERCENT ACROSS THE AREA...HIGHEST OVER THE MOUNTAINS. FOR NEXT WEEK...THE GFS SHOWS THE UPPER LEVEL HIGH RETROGRADING WESTWARD WHICH WILL RESULT IN HIGHER SUBSIDENCE ALOFT OVER THE EASTERN PLAINS. THIS MAY ENOUGH TO LIMIT TSTORM DEVELOPMENT EAST OF I25...WITH SHOWERS AND TSTORMS CONTINUING OVER THE HIGHER TERRAIN OF SOUTHEAST WYOMING. ECMWF STILL SHOWS THIS HIGH FURTHER EAST WITH TSTORM ACTIVITY MORE WIDESPREAD ACROSS THE FORECAST AREA. KEPT POP BETWEEN 10 TO 20 PERCENT FOR NOW EAST OF THE LARAMIE RANGE DUE TO UNCERTAINTY WITH THE POSITION OF THE UPPER LEVEL HIGH. MAX AND MIN TEMPERATURES WILL REMAIN WELL ABOVE NORMAL THROUGH THE WHOLE FORECAST PERIOD...WITH HIGHS IN THE MID TO UPPER 80S WEST OF THE LARAMIE RANGE...AND 90S ELSEWHERE. && .AVIATION...(FOR THE 00Z TAFS THROUGH 00Z THURSDAY AFTERNOON) ISSUED AT 542 PM MDT WED JUL 10 2013 VFR CONDITIONS WILL CONTINUE OVER THE CWA THROUGH FRIDAY. PATCHY LOW CLOUDS AND FOG MAY BE POSSIBLE ALONG AND JUST EAST OF THE SOUTHERN LARAMIE RANGE BETWEEN 08Z AND 15Z. SOME THUNDERSTORMS WILL CONTINUE OVER THE EAST PART OF THE CWA THROUGH 05Z. THEN AFTER A DRIER DAY THURSDAY...MORE LATE DAY STORMS CAN BE EXPECTED FOR FRIDAY. BRIEF MVFR CEILINGS AND VISIBILITIES IN RAIN WILL BE POSSIBLE WITH THE ACTIVITY. && .FIRE WEATHER... ISSUED AT 158 PM MDT WED JUL 10 2013 NO CONCERNS EXPECTED AS WEATHER ELEMENTS ARE EXPECTED TO REMAIN NON-CRITICAL OTHER THAN SOME LOW AFTERNOON RELATIVE HUMIDITIES OVER PARTS OF SOUTHEAST WYOMING ON THURSDAY. WIDELY SCATTERED SHOWERS AND THUNDERSTORMS WILL OCCUR INTO THIS EVENING MAINLY OVER SOUTHEAST PARTS OF THE CWA...WITH MORE WIDESPREAD ACTIVITY IN THE AFTERNOONS AND EVENINGS FRIDAY INTO EARLY NEXT WEEK AS SOME MONSOONAL-TYPE MOISTURE MOVES ACROSS THE REGION. && .CYS WATCHES/WARNINGS/ADVISORIES...
