.DISCUSSION...
A PLUME OF SUBTROPICAL MOISTURE IS NOW CENTERED OVER CNTL NEB THIS
AFTERNOON. THIS PLUME SHOULD CONTINUE TO DRIFT EAST OVERNIGHT AND
ALONG WITH A COLD FRONT CURRENTLY OVER WRN SD AND NERN WY BECOME THE
FOCUS FOR TSTM DEVELOP LATE MONDAY AFTN AND EVENING. WITH THE BEST
MOISTURE EAST OF THE FCST AREA SIGNIFICANT RAINFALL WEST ACROSS THE
FCST AREA IS QUESTIONABLE. NONETHELESS...SPC EXPANDED THE SLIGHT RISK
AREA SOUTH TO NEAR THE KS BORDER. CAPE AND SHEAR HAVE INCREASED
SUFFICIENTLY TO INCLUDE THE POTENTIAL FOR LARGE HAIL BUT WIND DAMAGE
IS THE MAIN CONCERN. THE NAM SUGGESTED IGNITION BETWEEN KTIF AND KANW
LATE MONDAY AFTN. CONDITIONS COULD BE FAVORABLE AS FAR WEST AS KOGA
THOUGH.

THE COLD FRONT SHOULD BE THROUGH THE FCST AREA BY TUESDAY MORNING. A
WARM FRONT QUICKLY DEVELOPS TUESDAY NIGHT AND ANOTHER ROUND OF STORMS
IS EXPECTED TO DEVELOP DURING THE DAY TUESDAY. CAPE AND SHEAR WILL
BECOME QUITE STRONG BUT CENTERED MORE OVER SCNTL NEB. THUS STORM
ACTIVITY IS EXPECTED FARTHER SOUTH WEDNESDAY VS NRN NEB MONDAY.

ANOTHER COLD FRONT WILL PUSH THROUGH THURSDAY MORNING WITH DRY
WEATHER EXPECTED THROUGH NEXT WEEKEND. THE ECMWF SUGGESTED A CHANCE
OF TSTMS NEXT WEEKEND BUT GIVEN THE VERY DRY CONDITIONS OF LATE THE
FCST WILL STICK WITH JUST TWO OPPORTUNITIES FOR RAIN DURING THE
NEXT 7 DAYS.

OTHER HIGHLIGHTS...ONE MORE DAY OF TEMPS NEAR OR ABOVE 90 ON
MONDAY. SOUTH WINDS COULD APPROACH WIND ADZY CRITERIA ALONG AND EAST
OF HIGHWAY 281 DURING THE AFTN. THE NAM SAYS YES THE GFS NO. SO WE
WILL WAIT ANOTHER MODEL RUN OR LONGER BEFORE CONSIDERING A WIND
ADVISORY. HPC SUGGESTED LOW TO MID 80S THURSDAY AND BEYOND AS A
GRADUAL WARMING TREND COULD DEVELOP ALTHOUGH NOT NEARLY AS STRONG
THE PREVIOUS BOUT OF 90S. IN FACT...THE ECMWF AND TO A CERTAIN
EXTENT THE GFS/GFSX SHOW PERSISTENT CANADIAN/PACIFIC HYBRID SFC HIGH
PRESSURE BUILDING THROUGH THE PLAINS AND MISSOURI BASIN WHICH WOULD
MOST LIKELY PRODUCE SEASONABLE TEMPS WITH HIGHS IN THE 80S AND LOWS
IN THE 50S.

&&

.AVIATION...
VISUAL FLIGHT RULES ANTICIPATED THROUGH 18Z MONDAY. A COLD FRONT
WILL MOVE SOUTHEAST ON MONDAY THAT WILL IMPACT WINDS BEYOND THE
PERIOD. FEW HIGH CLOUDS WILL CONTINUE TO LIFT NORTHEAST OVERNIGHT
WITH NO IMPACTS AT TERMINALS KLBF AND KVTN UNTIL NEAR 30/21Z. ATTM A
FEW HIGH BASED STORMS MAY DEVELOP THIS EVENING THAT COULD PRODUCE
STRONG WIND GUSTS WITH CB MENTIONED AT THIS TIME AT TERMINAL KVTN.
OTHERWISE CHANCE FOR STORMS INCREASE TOMORROW AS FRONT MOVES
SOUTHEAST.
