.DISCUSSION...

SURFACE LOW PER CURRENT OBS LOCATED SOMEWHERE NEAR PRATT.  AS UPPER
FLOW CONTINUES TO BECOME MORE SOUTHWESTERLY AS UPPER TROF
APPROACHES...CENTER OF LOW PRESSURE PROGGED TO REDEVELOP IN THE
EASTERN COLORADO PLAINS.  PRESSURE FALLS ALONG THE FRONT RANGE
INDICATING THIS IS THE CASE.

FOCUS FOR TONIGHT WILL BE ON FRONTAL BOUNDARY DRAPED ACROSS THE
NORTHERN COUNTIES ATTM...AND WHAT CONVECTION MAY FORM NEAR THE LOW
IN SOUTH CENTRAL KANSAS. BOUNDARY HAS MADE A LATE DAY RUN INTO THE
NEBRASKA COUNTIES ON ITS EAST SIDE...AND REMAINS DRAPED SOUTHWARD
INTO REPUBLIC AND POSSIBLY CLOUD COUNTIES ATTM.  COULD SEE A STORM
FIRE ALONG THE BOUNDARY IN THE NORTH CENTRAL COUNTIES...AND THINK WE
HAVE ENOUGH INSTABILITY THAT COLD POOLS FROM CONVECTION NORTH COULD
SET OFF A STORM OR TWO IF THEY GO IN THE NEXT HOUR OR TWO. SECOND
LOCATION FOR POSSIBLE STORM DEVELOPMENT IS NEAR THE SURFACE LOW IN
SC KS WHERE DRY AIR MAY AID IN INITIATING DEVELOPMENT. THESE STORMS
WOULD LIFT NORTH NORTHEAST IF SO BECOME A THREAT TO OUR WESTERN
COUNTIES LATER THIS EVENING.

OVERNIGHT PRIMES THE AREA FOR TOMORROW...AS 700MB +14C TEMPS SURGE
BACK NORTHWARD WELL IN TO NEBRASKA AND BRING THE CAP BACK IN. 850MB
LLJ OF 60-65KTS KEEPS RICH THETA E AIR UNDERNEATH IN PLACE. SURFACE
GRADIENT ALSO INCREASES AS LOW DEEPENS AND TROF APPROACHES. THIS
WILL KEEP WINDS BREEZY OVERNIGHT AND OVERNIGHT LOWS IN THE 70S.

BY 18Z THURSDAY...110KT UPPER JET MOVES INTO WESTERN KS.  700MB
WINDS ARE GENERALLY 60KTS OVER CTRL KS WITH 850MB WINDS BECOMING
50KTS BY 0Z.  THIS NOT ONLY LEAVES 55KTS OF 0-6KM BULK SHEAR IN
PLACE...IT ALSO SETS UP AN ENVIRONMENT FOR STORM MOTIONS TO THE
NORTH NORTHEAST ON THE ORDER OF 40-60KTS.  EXPECT THAT EVENT WILL
UNFOLD SUCH THAT STORMS BEGIN TO FIRE IN CTRL TO S CTRL KS AS UPPER
TROF MOVES IN AND WEAKENS CAP...AND INTERSECTS THE DRYLINE.  COULD
ALSO SEE A FEW STORMS DEVELOP IN THE WARM SECTOR AS CAP ERODES IN
THE LATE AFTERNOON OUT AHEAD OF THE INCOMING FRONT.  EXPECT A LINE
OF STORMS TO FORM ACROSS CTRL KS AND TRAIN NORTH THROUGH THE LINE AS
THE WHOLE SYSTEM SLOWLY PUSHES EAST. CAPES IN THE 3000J/KG RANGE
COUPLED WITH SHEAR WILL MAKE PRIME ENVIRONMENT FOR SUPERCELLS.  THIS
WILL ALSO BRING POTENTIAL PROBLEMS WITH FLOODING AS STORMS
REPEATEDLY DEVELOP AND MOVE THROUGH THE LINE AND MAY BRING ROUND
AFTER ROUND OF RAINFALL.

THURSDAY NIGHT...UPPER LEVEL LOW MOVES SLOWLY NORTHEAST THURSDAY
NIGHT WITH ATTENDANT SURFACE BOUNDARY MOVING EAST ACROSS EASTERN KS
OVERNIGHT. EXPECT THE POTENTIAL FOR SUPERCELLS TO CONTINUE THROUGH
THE EVENING HOURS...BEFORE STORMS BECOME LINEAR LATE. LATER SHIFTS
MAY ALSO NEED TO POST A FLASH FLOOD WATCH GIVEN THAT MUCH OF OUR CWA
HAS HAD SIGNIFICANT RAINFALL OVER THE PAST SEVERAL DAYS. SATURATED
GROUND AND MINOR FLOOD PROBLEMS WILL BE AGGRAVATED BY ADDITIONAL
RAINFALL.

MADE FEW IF ANY CHANGES TO FRIDAY AND THE FORECAST FOR THE WEEKEND
AS FOCUS IS ON SEVERE POTENTIAL FOR THURSDAY/THURSDAY NIGHT.
HOWEVER...KEPT POPS GOING IN EASTERN CWA FRIDAY. ON SATURDAY...MAY
SEE NORTHERN PORTION OF THE CWA CLIPPED BY STORMS FROM THE MCS IN
EASTERN NEBRASKA. NEXT SHORT WAVE TROF TO MOVE THROUGH THE CWA
SUNDAY NIGHT AND MONDAY. ATMOSPHERE RECOVERS FAIRLY QUICKLY
FOLLOWING THE FROPA LATE THURSDAY NIGHT AND FRIDAY...SO WARM AND
HUMID CONDITIONS ARE EXPECTED.

LEANED TOWARD HPC GUIDANCE FOR MONDAY...TUESDAY AND WEDNESDAY.

&&

.AVIATION...

MAINLY A WIND FORECAST FOR THIS TIME PERIOD ALTHOUGH BY NEXT TAF
ISSUANCE MAY SEE A NEED FOR TS AT THE MHK FOR THE EARLY EVENING
HOURS. STRONG UPPER SYSTEM APPROACHES THE AREA OVERNIGHT AND WILL
KEEP WINDS UP OVER 12 KTS AND INCREASE TO ABOVE 20KTS BY TOMORROW
MORNING. ALSO EXPECT TO SEE SCATTERED CU AROUND 3KFT IN STRONG WARM
AIR ADVECTION REGIME.  COULD BE LOCALLY BKN030 BUT NOT CONVINCED
ENOUGH TO ADD TO A TAF SITE YET.

.TOP WATCHES/WARNINGS/ADVISORIES...NONE.
