ISSUED AT 335 AM CDT THU JUL 23 2015 SCATTERED THUNDERSTORMS CONTINUE TO DEVELOP ACROSS FAR SOUTHERN KS NORTH OF AN E-W ORIENTED 925-MB FRONT NO DOUBT SITUATED IN A MOISTURE-RICH ENVIRONMENT. THE ELEVATED FRONT IS NEARLY STATIONARY & AS SUCH THE THUNDERSTORMS SHOULD CONTINUE TO HUG THE OK BORDER THIS MORNING. WITH THE E-W ORIENTED SURFACE FRONT EXTENDING ALONG JUST S OF THE OK/KS BORDER AN EAST/SOUTHEAST WIND OF 10 MPH OR LESS CONTINUES TO PREVAIL ACROSS KICT COUNTRY. && .SHORT TERM...(TODAY THROUGH SATURDAY) ISSUED AT 335 AM CDT THU JUL 23 2015 TODAY: THE PRIMARY...IF NOT SOLE...PROBLEM IS DETERMINING HOW FAR N/NE THUNDERSTORMS WILL VENTURE INTO SOUTH-CENTRAL & ESPECIALLY SOUTHEAST KS. WITH THE FRONT LIKELY TO GET POORLY DEFINED AS THE MORNING PROGRESSES...ANY CHANCES OF THUNDERSTORMS WOULD BE LIMITED TO THIS MORNING...ESPECIALLY WITH MID-LEVEL RIDGING INDUCING FAIRLY STRONG WARM ADVECTION THAT WOULD PUT A LID ON ANY FURTHER DEVELOPMENT...ESPECIALLY ACROSS WESTERN & CENTRAL KS. TONIGHT-FRI: WITH THE STRONG(!) MASSIVE UPPER-DECK RIDGE CONTINUING TO AMPLIFY ACROSS THE UPPER MS VALLEY THE CAP WOULD LIKELY BE SAFETY-SEALED. THE PASSWORDS FOR FRI AFTERNOON ARE STILL HEAT & HUMIDITY. WITH INDICES FROM 105-108 PROJECTED FOR NEARLY ALL AREAS ALONG & E OF I-135 CHANCES ARE INCREASING THAT A HEAT ADVISORY WILL BE ISSUED FOR THESE AREAS FRI AFTERNOON. STRONGLY CONSIDERED ISSUING BUT WITH NEIGHBORING WFOS DEFERRING WILL BE "CHECKING THE SWING" ON ISSUANCE. WILL FOR SURE "TURN UP THE HEAT" IN THE HWO. FRI NIGHT-SAT NIGHT: A WEAK MID-LEVEL SHORTWAVE MAY STILL DEVELOP OVER EASTERN CO FRI NIGHT. IN RESPONSE...A COOL FRONT WILL ATTEMPT TO MOVE SSE INTO NORTHWEST KS LATE FRI NIGHT. WITH THE MID-LEVEL SHORTWAVE DISSIPATING THE FRONT WOULD STALL VERY CLOSE TO THE NEBRASKA/KS BORDER LATE FRI NIGHT/EARLY SAT MORNING. WITH SUCH HIGH OCTANE FUEL ENTRENCHED ACROSS THE AREA THUNDERSTORM CHANCES WOULD INCREASE FROM WEST/NORTHWEST KS TO ALONG THE NEBRASKA/KS BORDER. A 20-30% POP ASSIGNMENT IS WARRANTED FOR THE NORTHWEST HALF OF CENTRAL KS. FOR SAT NIGHT...THUNDERSTORMS DEVELOPING OVER NORTHWEST KS & SOUTHWEST NEBRASKA MAY KICK THE FRONT FURTHER SE TOWARD CENTRAL KS. ALTHOUGH THERE IS SOME DISAGREEMENT BETWEEN THE GFS & ECMWF ON FRONTAL POSITIONING HAVE CONTINUED TREND OF SLOWLY INCREASING POPS TO 30-40% ACROSS CENTRAL KS WITH A NW-SE GRADIENT ACROSS CENTRAL KS. .LONG TERM...(SUNDAY THROUGH WEDNESDAY) ISSUED AT 335 AM CDT THU JUL 23 2015 THUNDERSTORM CHANCES SHOULD SLOWLY INCREASE AS THE WEEK PROGRESSES AS THE MID-UPPER DECK TROF PUSHES E FROM THE NORTHERN/CENTRAL ROCKIES TO THE DAKOTAS MON NIGHT & TUE. THE GREATEST THUNDERSTORM BEST CHANCES SHOULD BE TUE NIGHT & WED...FOR IF THE MID-UPPER SHORTWAVE SHEARS THE ATTENDANT SURFACE FRONT WOULD LIKELY STALL IN A ROUGHLY E-W MANNER ACROSS CENTRAL KS. THE PRESENCE OF THE FRONT WOULD CAUSE THE THERMOSTATS TO BE TURNED DOWNED THE MIDDLE OF NEXT WEEK. && .AVIATION...(FOR THE 12Z TAFS THROUGH 12Z FRIDAY MORNING) ISSUED AT 644 AM CDT THU JUL 23 2015 MAIN AVIATION CONCERN WILL BE CONVECTIVE TRENDS THIS MORNING. STORMS DEVELOPED SEVERAL HOURS AGO OVER SOUTHERN KS IN AN AREA OF STRONG ISENTROPIC LIFT ALONG THE 310K SURFACE WITH A TIGHT 700MB BAROCLINIC ZONE STRETCHING ACROSS SOUTH CENTRAL KS. THESE STORMS SHOULD CONTINUE FOR THE NEXT FEW HOURS BEFORE DECREASING IN COVERAGE. 40 MPH WINDS AND HEAVY RAIN WILL BE THE MAIN THREATS. BY THE AFTERNOON...MOSTLY CLEAR SKIES WILL BE IN PLACE WITH THIS EXPECTED TO CONTINUE THROUGH THE OVERNIGHT HOURS AS UPPER RIDGING STARTS TO BUILD OVER THE SOUTHERN PLAINS.
