AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE CHEYENNE WY 511 PM MDT FRI AUG 23 2013 .SHORT TERM...(THIS EVENING THROUGH SUNDAY NIGHT) ISSUED AT 300 PM MDT FRI AUG 23 2013 SO FAR JUST A FEW SMALL SHOWERS AND STORMS OCCURRING OVER THE SOUTHERN MOUNTAINS...LIKELY DUE TO SOMEWHAT WARMER MID-LEVEL TEMPERATURES. NICE BATCH OF MOISTURE AND AN EMBEDDED SHORTWAVE EVIDENT ON SATELLITE MOVING NORTH ACROSS UTAH SHOULD REMAIN GENERALLY WEST OF THE CWA BUT A GLANCING SHOT OF ENERGY MAY KEEP SOME CONVECTION GOING OVER THE WESTERN CWA THROUGH THIS EVENING. FARTHER EAST INHIBITION SHOULD LIMIT ACTIVITY THUS HAVE NUDGED POPS DOWN A BIT EAST OF THE MTNS. LITTLE CHANGE SEEN THROUGH THE WEEKEND WITH THE BEST CHANCE FOR CONVECTION REMAINING OVER WESTERN PARTS OF THE CWA WHERE THE SUBTROPICAL MOISTURE PLUME SHOULD EXIST.

CHANCES FOR SEVERE THUNDERSTORMS ON THE LOW SIDE GIVEN WARM TEMPERATURE PROFILES AND WEAK SHEAR. EXTENDED MODELS SHOWING THE UPPER RIDGE EXPANDING NORTH AND WEST MID TO LATE NEXT WEEK.
