DISCUSSION...

SFC ANALYSIS SHOWS LOW OVER NW KS AND OVER SOUTH CENTRAL SOUTH
DAKOTA ATTM WHICH IS MORE IN LINE WITH THE NGM SOLUTION THAT THE
ETA. IN ANY CASE...NEITHER NGM/ETA DID WELL CONCERNING THE MOISTURE
OVER THE REGION AS MODELS PUSHED TROF/DRYLINE THROUGH THE CENTRAL
PORTIONS OF THE REGION BY THIS TIME. SFC ANALYSIS SHOWS TROF/DRYLINE
LOCATED ALONG FAR WESTERN SECTIONS OF THE CWA WITH DEWPOINTS IN THE
60S ALONG AND AHEAD OF THIS FEATURE.

THIS HAS RESULTED IN A VERY MOIST AND UNSTABLE ATMOSPHERE ACROSS
MUCH OF THE REGION. TROF/DRYLINE TO SLOWLY MOVE THROUGH WESTERN AND
CENTRAL PORTIONS OF THE AREA THIS EVENING...BUT LACK OF UPPER LEVEL
SUPPORT DURING TIME OF GREATEST INSTABILITY AS WELL AS WARM 7H
TEMPERATURES TO LIMIT CONVECTIVE ACTIVITY. WITH HIGH CAPES
(3500-4000) OVER THE AREA ANY ACTIVITY THAT DOES FIRE WILL RAPIDLY
STRENGTHEN. POSSIBILITY OF SEVERE WEATHER REMAINS OVER THE REGION
THROUGH MID EVENING...PERHAPS SLIGHTLY FURTHER WEST THAN INDICATED
BY SELS.

UPPER LEVEL SUPPORT DOES MOVE IN DURING THE LATE EVENING WHILE 7H
TEMPS BEGIN COOLING. THIS SHOULD BE ENOUGH TO TRIGGER WIDELY
SCATTERED THUNDERSTORMS ACROSS THE REGION. BEST CHANCES OVER THE
NORTHERN CWA SO WILL SUPPORT 30% POPS THERE.

TEMP FORECAST ON TRACK FOR TONIGHT SO NO CHANGES NEEDED THERE.

COLD FRONT MOVES THROUGH A LARGE PORTION OF THE CWA BY THE EARLY
DAYLIGHT HOURS. 5H LOW SLOWS WAY DOWN...LOW PRESSURE AREA TO DEVELOP
OVER SOUTHERN WYOMING. FRONT TO THEN STALL OUT. SOUTHEAST WINDS
AHEAD OF FRONT TO KEEP TEMPS WARM ACROSS SOUTHERN ZONES.

VORT MAX IS EXPECTED TO SWING THROUGH THE WEST SECTIONS OF THE
REGION DURING THE LATE AFTERNOON. ISOLATED TRW POSSIBLE IN COLORADO
ZONES. LACK OF LIFT PLUS WARM 7H TEMPS TO LIMIT ACTIVITY UNTIL
AFTER PERIOD OF CONCERN...ESPECIALLY OVER EASTERN SECTIONS OF THE
REGION. WILL COMPROMISE WITH CURRENT OMA FORECAST AND GO 20% TRW IN
SW NEBRASKA FOR SECOND PERIOD.
