LATEST WATER VAPOR IMAGERY SHOWS AN UPPER-LEVEL LOW OVER THE NRN
PLAINS WITH AN ASSOCIATED UPPER-LEVEL TROUGH EXTENDING SSWWD INTO
THE CNTRL HIGH PLAINS AND SRN ROCKIES. ISOLATED TO SCATTERED
THUNDERSTORMS ARE ONGOING JUST AHEAD OF THE UPPER-LEVEL TROUGH FROM
ERN NEB SWWD INTO FAR WEST TX. INSTABILITY HAS BECOME WEAK ALONG
THIS CORRIDOR SUGGESTING THE MARGINAL SEVERE WEATHER THREAT FROM

GREAT PLAINS IS FORECAST TO GRADUALLY STRENGTHEN OVERNIGHT AND MAY
SUPPORT THE DEVELOPMENT OF ELEVATED THUNDERSTORMS. NO SEVERE THREAT
IS EXPECTED THROUGH TONIGHT ACROSS THE CONUS.
