.DISCUSSION...

DAYS 1-2...

LATE THIS AFTERNOON INTO TONIGHT...
A CLUSTER OF THUNDERSTORMS DEVELOPED ACROSS EAST CENTRAL COLORADO
EARLY THIS AFTERNOON AND IS EXPECTED TO MOVE INTO OUR CWA LATE THIS
AFTERNOON INTO THIS EVENING AS THE UPPER LEVEL TROUGH MENTIONED
ABOVE MOVES TO THE EAST. THE BEST AREA TO RECEIVE PRECIPITATION FROM
THESE STORMS WILL BE ACROSS WESTERN PORTIONS OF OUR CWA THEN TAPPER
OFF AFTER SUNSET ACROSS CENTRAL PORTIONS OF OUR CWA. PARTLY CLOUDY
SKIES ARE EXPECTED FOR THE REMAINDER OF THE OVERNIGHT AS THE AXIS OF
THE TROUGH MOVES OUT OF OUR AREA. WINDS WILL GENERALLY BE FROM THE
NORTH AROUND 15 MPH SHIFTING TO THE NORTHEAST AND DECREASING TO 5 TO
10 MPH OVERNIGHT. HIGHS TODAY WILL RISE INTO THE AROUND 90 DEGREES
THEN FALL INTO THE UPPER 50S TO LOWER 60S FOR LOWS OVERNIGHT.

TOMORROW AND TOMORROW NIGHT...
THE UPPER LEVEL TROUGH WILL MOVE INTO THE MISSISSIPPI VALLEY WITH AN
UPPER LEVEL RIDGE OF HIGH PRESSURE BUILDING ACROSS OUR REGION.
TOWARDS THE SURFACE...HIGH PRESSURE WILL BUILD IN FROM THE WEST
WHICH SHOULD KEEP OUR AREA MOSTLY CLEAR AND DRY. WINDS WILL START
OUR FROM THE EAST THEN QUICKLY SHIFT TO THE SOUTH TO SOUTHEAST BY
AFTERNOON AND CONTINUE INTO THE OVERNIGHT PERIOD. HIGHS TOMORROW
WILL RANGE FROM THE UPPER 80S ACROSS THE NORTH TO LOWER 90S ACROSS
THE SOUTH. LOWS TOMORROW NIGHT WILL DIP INTO THE UPPER 60S.

THURSDAY...
THE NEXT UPPER LEVEL TROUGH WILL START TO DIG INTO THE PACIFIC
NORTHWEST WHICH WILL IN TURN SHIFT THE THE UPPER LEVEL RIDGE
SLIGHTLY TO THE EAST LEAVING OUR AREA IN SOUTHWEST FLOW ALOFT.
TOWARDS THE SURFACE...A WEAK AREA OF LOW PRESSURE IS ANTICIPATED TO
FORM ACROSS THE FRONT RANGE OF THE ROCKIES. THIS WILL CAUSE WINDS
WILL INCREASE FROM THE SOUTH AND SHIFT TO THE SOUTHWEST BY
AFTERNOON. VERY WARM CONDITIONS ARE EXPECTED IN THE AFTERNOON WITH
HIGHS ONCE AGAIN REACHING INTO THE TRIPLE DIGITS ACROSS MOST OF OUR
CWA. FIRE DANGER WILL BE ON THE INCREASE ACROSS WESTERN PORTIONS OF
OUR CWA. PLEASE SEE THE FIRE WEATHER SECTION FOR MORE INFORMATION.

DAYS 3-7...

CHALLENGES IN THE MEDIUM RANGE THURSDAY NIGHT THROUGH TUESDAY WILL
CENTER AROUND HIGH TEMPERATURES AND THUNDERSTORM CHANCES.
OVERALL...THE GOING FORECAST FOR THIS TIME RANGE IS NOT CHANGED THAT
MUCH.

A NOCTURNAL MCS WILL LIKELY MOVE ACROSS SOUTHERN NEBRASKA AND/OR
NORTHERN KANSAS OVERNIGHT THURSDAY NIGHT.  A WEAK SHORTWAVE TROUGH
RESPONSIBLE FOR THIS ACTIVITY WILL MOVE NORTHEAST AND BRING A WEAK
FRONT SOUTH INTO WESTERN KANSAS.  THIS FRONT WILL BE AUGMENTED BY
THE MCS OUTFLOW DURING THE NIGHT.  THE FRONT/OUTFLOW WILL THEN
BECOME STATIONARY DURING THE DAY FRIDAY.  THE FRONT ITSELF ACROSS
WESTERN KANSAS ON FRIDAY WILL BE DIFFICULT TO INITIATE STORMS ON AS
CONVERGENCE WILL LIKELY WEAKEN IN FAVOR OF CYCLOGENESIS OVER EASTERN
COLORADO.  A DRYLINE-FRONT INTERSECTION MAY BE A FOCUS FOR STORMS
ACROSS PORTIONS OF THE DDC FA BUT COVERAGE WILL LIKELY BE LIMITED
DUE TO WEAKENING CONVERGENCE AND FAIRLY STABLE MID LEVEL
TEMPERATURES.  EXCESSIVE HEAT FARTHER SOUTH IN WESTERN OKLAHOMA MAY
YIELD STORMS SOUTH OF THE FORECAST AREA WHICH IS WHAT THE ECMWF AND
NAM MODELS ARE HINTING AT. AN ENHANCED BAND OF UPPER LEVEL WINDS
WILL ALSO BE MOVING OUT ACROSS THE TEXAS PANHANDLE AND WESTERN
OKLAHOMA ON FRIDAY.  MUCH OF THE SAME IS EXPECTED SATURDAY WITH A
QUASISTATIONARY FRONT ACROSS WESTERN KANSAS.  VERY WARM MID LEVEL
TEMPERATURES WILL ONCE AGAIN LIMIT COVERAGE OF ANY CONVECTION THAT
FORMS IN THE HOT AIR.  WILL HAVE POPS AROUND 10 PERCENT AND KEEP THE
MENTION GOING IN THE HWO PRODUCT. ON SUNDAY...A SIGNIFICANT JET
STREAK WILL MOVE INTO THE CENTRAL PLAINS WITH MUCH STRONGER RESPONSE
AT THE SURFACE ACROSS NORTHWESTERN KANSAS.  A VERY HOT DAY IS
ANTICIPATED WITH TEMPERATURES LIKELY EXCEEDING 102F OVER ALMOST ALL
OF THE DDC FA AS THE FRONT LIFTS NORTH.  SOME OF THE TRADITIONALLY
HOT AREAS OF THE FORECAST AREA BETWEEN THE ARKANSAS RIVER AND THE
OKLAHOMA BORDER MAY SEE HIGHS IN THE 105 TO 108F TERRITORY.  BY
MONDAY...THE CONSENSUS AMONG THE MEDIUM RANGE MODELS IS THAT THE JET
STREAK WILL LIFT OUT ACROSS THE NORTHERN PLAINS AND MIDWEST AND PUT
KANSAS IN THE RIGHT-ENTRANCE REGION LEADING TO ENHANCED LOW LEVEL
CONVERGENCE ALONG THE TRAILING FRONT FROM THE LOW OVER THE MIDWEST.
THE SLOW MOVING FRONT MONDAY AND ENHANCED CONVERGENCE WOULD LEAD TO
THUNDERSTORM ACTIVITY ANYWHERE FROM CENTRAL KS TO CENTRAL OKLAHOMA.
WILL KEEP THE 20 POPS IN FOR THE SOUTH CENTRAL KS COUNTIES MONDAY
BUT THOSE MAY NEED TO BE INCREASED IN TIME.

&&

.AVIATION...

HAVE ADDED CB TO THE CLOUD GROUP FOR KGCK AND KDDC FOR ABOUT A 3 OR
4 HOUR PERIOD LATE THIS AFTN AND EARLY THIS EVENING AS A
THUNDERSTORM CLUSTER MOVES EAST-SOUTHEAST INTO SOUTHWEST KANSAS. TAF
AMENDMENT WILL LIKELY BE NEEDED AS THIS COMPLEX OF STORMS
APPROACH.  AFTER THE THUNDERSTORM COMPLEX DIES OUT OR MOVES
THROUGH...WINDS WINDS WILL EVENTUALLY BECOME LIGHT AND VARIABLE
LATER ON TONIGHT AS A WEAK HIGH PRESSURE ARE AFFECTS THE REGION
BEHIND THE UPPER AIR DISTURBANCE.

&&

.FIRE WEATHER...

A WEAK AREA OF LOW PRESSURE WILL FORM ACROSS CENTRAL COLORADO ON
THURSDAY. SOUTHERLY WINDS WILL SHIFT TO THE SOUTHWEST BY AFTERNOON
AND INCREASE IN INTENSITY DURING THE AFTERNOON AND EARLY EVENING.
HIGHS DURING THE DAY WILL REACH INTO AROUND 100 WITH SOME AREAS
FORECASTED TO REACH ABOVE 100 DEGREES. DRY CONDITIONS WILL ALSO BE
FOUND ACROSS WESTERN PORTIONS OF OUR CWA. WITH ALL THESE INGREDIENTS
COMBINED FIRE HAZARDS WILL INCREASE AND WE HAVE ISSUED A FIRE
WEATHER WATCH TO ACCOUNT FOR THIS. FUTURE MODEL RUNS WILL BE WATCHED
FOR FIRE HAZARDS AND THIS AREA MAY BE UPGRADED TO A RED FLAG WARNING
TOMORROW.
