NWS North Platte, NE wrote its last area forecast discussion before this severe thunderstorm warning went out at Aug 31, 6:01 PM CDT, 3 hours 37 minutes earlier.

Area forecast discussion, Aug 31, 6:01 PM CDT, 3 hours 37 minutes before

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. NO THUNDERSTORMS ARE
FCST AT KVTN. ELSEWHERE...FROM ROUGHLY KOGA-KANW AND
EAST...ISOLATED THUNDERSTORM COVERAGE IS EXPECTED THROUGH 06Z.
DUE TO CURRENT RADAR TRENDS AND ISOLATED COVERAGE
EXPECTED...NO THUNDERSTORMS FCST AT KLBF THIS EVENING. NORTH WINDS
BEHIND THE COLD FRONT MAY GUST TO AROUND 15 KTS THIS
EVENING...THEN UP TO 10 KTS OVERNIGHT INTO SUNDAY AFTERNOON.

.LBF WATCHES/WARNINGS/ADVISORIES...
NONE.
