...UPDATE TO AVIATION...
.DISCUSSION...
TONIGHT...HIGH PRESSURE REMAINS FIRMLY IN PLACE THROUGH THE NEXT 24
HOURS OVER THE CENTRAL PLAINS. A SLIGHT CHANCE OF ISOLATED
SHOWERS OR BRIEF THUNDERSTORMS WILL BE POSSIBLE THIS EVENING
ACROSS FAR NORTH CENTRAL KANSAS. AS OF EARLY THIS AFTERNOON...AN
AGITATED CUMULUS FIELD WAS MATERIALIZING FROM LIBERAL TO HAYS.
SOME OF THIS ACTIVITY HAS MATURED INTO SCT SHOWERS/THUNDERSTORMS
OVER SW KS. WITH ALREADY ERODED INHIBITION IN MANY SECTIONS OF THE
AFOREMENTIONED CORRIDOR...CANNOT RULE OUT ADDITIONAL BRIEF
CONVECTION ALONG AND JUST LEFT OF THE MAIN HEAT AXIS. SOME OF THIS
ACTIVITY MAY SLIDE INTO FAR NORTH CENTRAL SECTIONS OF THE
CWA...BUT IS UNLIKELY TO ALLEVIATE MUCH OF THE HOT CONDITIONS
PRESENT. FOR THE REMAINDER OF THE AREA...THE PROBABILITY OF
PRECIPITATION REMAINS LOW TONIGHT. SEVERAL MODELS ATTEMPT TO
DEVELOP A COMPLEX OF THUNDERSTORMS OVER SE NEBRASKA AND MOVE THE
ACTIVITY INTO PORTIONS OF THE CWA. A SIMILAR SCENARIO WAS
SUGGESTED LAST NIGHT...WHICH FAILED TO MATERIALIZE...AND WITH NO
APPRECIABLE UPPER WAVE ANALYZED AND CURRENT THUNDERSTORMS NORTH OF
I-80 MOVING ENE...DO NOT SEE ENOUGH EVIDENCE TO JUSTIFY POP
MENTION IN FORECAST FOR OTHER SECTIONS OF THE CWA. COVERAGE AND
INTENSITY OF ANY CONVECTION WILL GRADUALLY LESSEN A COUPLE HOURS
POST-SUNSET.
SATURDAY...EXCESSIVE HEAT IS THE MAIN STORY WITH MAXIMUM AIR
TEMPERATURES EXPECTED TO REACH 97 NORTHEAST TO 104 SOUTHWEST
SECTIONS OF THE CWA. AFTERNOON HEAT INDICES WILL RANGE FROM 105 TO
112. A FEW MID LEVEL CLOUDS MAY MOVE THROUGH THE REGION...BUT SHOULD
DO LITTLE TO AFFECT ANTICIPATED TEMPERATURES.
BLAIR
VERY LITTLE CHANGE TO THE EXTENDED AS THE HEAT CONTINUES THROUGH
NEXT WEEK. WENT AHEAD AND EXTENDED THE WARNING THROUGH WEDNESDAY AS
APPROACHING WESTERN TROF HAS SLOWED A BIT. NOW LOOKS LIKE WE WILL
GET PARKED UNDER ANOTHER THERMAL RIDGE POSSIBLY THURSDAY WITH
DEWPOINTS FALLING BACK INTO THE 60S. DONT HAVE MUCH CONFIDENCE THAT
WAVES MOVING OUT OF THE SOUTHWEST INTO THE ROCKIES AND ACROSS THE
NORTHERN PLAINS WILL HAVE MUCH IMPACT ON THE RIDGE. WONT BE
SURPRISED IF THE HEAT LINGERS INTO LATE WEEK BUT HAVE CARRIED THE
WARNING AS FAR AS CONFIDENCE ALLOWS AT THIS POINT.

.AVIATION...
VFR CONDITIONS WILL CONTINUE THROUGH THE PERIOD. CONVECTION MAY
ADVANCE INTO THE MHK TAF SITE AND WILL CONTINUE TO MONITOR FOR
THIS TREND. TOP AND FOE SHOULD REMAIN FREE OF ANY CONVECTION
TONIGHT WITH ANY ACTIVITY TO THE NORTH OF THE TERMINALS.
