AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE NORTH PLATTE NE 601 PM CDT SAT AUG 31 2013 .SHORT TERM...(THIS EVENING THROUGH SUNDAY) ISSUED AT 239 PM CDT SAT AUG 31 2013 AN UPPER LEVEL DISTURBANCE...CURRENTLY ACROSS NCNTL NEB AT 20Z WILL MOVE QUICKLY EAST PRODUCING SCATTERED TSTMS THIS AFTN AND EVENING. IT WOULD APPEAR THAT THIS WAVE COULD EXIT THE NRN PORTION OF THE FCST AREA BY 22Z...PERHAPS AROUND 02Z IN THE SOUTH. THEREAFTER NORTH WINDS TAKE HOLD AND SWEEP INSTABILITY SOUTH AND EAST OF THE FCST AREA. SATELLITE PRECIPITABLE WATER IS INCREASING BENEATH THE DISTURBANCE AND LOCATE THE MOISTURE PLUME EAST OF THE MODEL POSITION SO A FASTER EXIT IS POSSIBLE. NONETHELESS...ANY STORMS WHICH DEVELOP LATE THIS AFTN AND THIS EVENING COULD BECOME SEVERE...ESPECIALLY ALONG AND EAST OF HIGHWAY 281 IN THE NORTHEAST. FARTHER WEST AND SOUTH...THE SEVERE WEATHER POTENTIAL BECOMES MORE CONDITIONAL. BASED ON SATELLITE AND MODEL DATA...STORMS COULD BECOME SEVERE...BUT SHEAR COULD BE A LIMITING FACTOR. DEEP MOISTURE AND UNIDIRECTIONAL SHEAR ALOFT WOULD CERTAINLY SUPPORT MULTICELL BEHAVIOR AND LOCALLY HEAVY RAINFALL. ALL STORM ACTIVITY SHOULD EXIT THE FCST AREA BY 06Z-09Z WITH CLEARING SKIES THEREAFTER. THE MODELS THEN PULL HIGH PRESSURE...CURRENTLY ACROSS MT...THROUGH THE UPPER MIDWEST WHICH WILL PRODUCE BACK DOOR COOLING FROM THE NORTHEAST. THUS COOLEST HIGHS SUNDAY WILL BE ACROSS THE NORTHEAST WITH HIGHS NEAR 80 AND MID TO NEAR UPPER 80S ACROSS THE SOUTH AND WEST. .LONG TERM...(SUNDAY NIGHT THROUGH SATURDAY) ISSUED AT 239 PM CDT SAT AUG 31 2013 THE STRONG UPPER RIDGE BUILDS BACK OVER THE SOUTHERN ROCKIES AND HOT DRY WEATHER RETURNS TO THE CENTRAL PLAINS TUESDAY. ALTHOUGH MOISTURE RETURNS...THE WARM AIR ALOFT RETURNS AS WELL AND VERTICAL MOTION OVER THE SURFACE BOUNDARY IS CAPPED AS INDICATED WITH 500MB TEMPERATURES -5C OR WARMER. A FRONT STALLS ACROSS SOUTH DAKOTA BY WEDNESDAY AND CONTINUES STALLED THERE WITH ONLY SMALL OSCILLATIONS SOUTH AND BACK TO THE NORTH. THE RESULT OF THAT IS LOW PROBABILITY OF PRECIPITATION AND PERSISTENT ABOVE AVERAGE TEMPERATURES. && .AVIATION...(FOR THE 00Z TAFS THROUGH 00Z SUNDAY EVENING) ISSUED AT 600 PM CDT SAT AUG 31 2013 THE UPPER DISTURBANCE FORECAST TO PRODUCE THUNDERSTORMS THIS EVENING WILL MOVE ACROSS SOUTHEASTERN AREAS.
