NWS Dodge City, KS wrote its last area forecast discussion before the first event at Jul 30, 2:34 PM CST, 1 hour 39 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE DODGE CITY KS 334 PM CDT SAT JUL 30 2011 .DISCUSSION... DAYS 1-2... THE MAIN FORECAST CHALLENGES ARE CHANCES FOR SCATTERED THUNDERSTORMS LATE THIS AFTERNOON UNTIL EARLY EVENING. HIGH TEMPERATURES SUNDAY AND MONDAY AND POSSIBLE FIRE WEATHER CONDITIONS MONDAY AFTERNOON. AFTER A NORTHERN BRANCH SHORTWAVE TROUGH MOVES ACROSS THE NORTHERN PLAINS THIS EVENING, UPPER LEVEL RIDGING WILL AMPLIFY INTO THE PLAINS INTO MONDAY. THIS WILL PROVIDE ANOTHER HOT AIRMASS TO PUSH INTO WESTERN KANSAS WITH HIGH TEMPERATURES WELL ABOVE THE CENTURY MARK. CURRENT HEAT ADVISORY IN THE EAST FA FOR SUNDAY AFTERNOON AND EARLY EVENING STILL LOOKS GOOD AND MAY NEED ANOTHER ONE FOR MONDAY AFTERNOON AND EVENING. FOR TONIGHT WIDELY SCATTERED THUNDERSTORMS COULD POP UP ALMOST ANYWHERE BASED ON LATEST MESOSCALE MODELS AND SHORT FUSE COMPOSITE, SO WILL GO WITH A SMALL POP TO COVER. VERY LITTLE TO NO DEEP LAYER SHEAR IS IN PLACE SO ANY STORMS THAT GO UP WILL NOT LAST VERY LONG AND AS THEY COLLAPSE COULD PRODUCE SOME WIND GUSTS TO 50 MPH. THEN MORE SCATTERED STORMS COULD DEVELOP UNTIL SUNSET ALONG ANY OUTFLOW BOUNDARIES. OVERNIGHT LOWS WILL RANGE FROM THE LOW 70S WEST TO THE UPPER 70S SOUTHEAST. SOUTHWEST WINDS WILL BE LIGHT AROUND 5 MPH. ON SUNDAY WITH MOSTLY SUNNY SKIES LOOK FOR HIGHS AROUND 100 WEST TO 107 IN THE EAST FA. DEWPOINTS ALONG WITH HIGH TEMPERATURES IN THE EAST WILL PRODUCE HEAT INDICES ABOVE 105 WITH CURRENT HEAT ADVISORY IS IN PLACE. FOR SUNDAY NIGHT SKIES WILL BE MOSTLY CLEAR BUT WINDS WILL STAY SOUTHERLY FROM 10 TO 15 MPH AND KEEP LOWS IN THE LOW 70S WEST TO THE UPPER 70S EAST. FOR MONDAY WITH 850MB TEMPERATURES CLIMBING TO AROUND 32C OUR HIGH TEMPERATURES WILL CLIMB WELL OVER THE CENTURY MARK. EXPECT 104 WEST TO 107 AT DODGE TO AROUND 110 AT MEDICINE LODGE. WINDS WILL ALSO PICK UP TO 15 TO 25 MPH IN THE AFTERNOON. .FIRE WEATHER... SOUTH TO SOUTHWEST WINDS WILL BE 15 TO 25 MPH AND LOWEST RELATIVE HUMIDITIES WILL APPROACH 15 PERCENT. CURRENTLY THESE CONDITIONS ARE BORDERLINE FOR A FIRE WEATHER WATCH AND WILL LET NEXT SHIFTS RE-EVALUATE FOR NOW. DAYS 3-7... THE EXTENDED PERIOD BEGINS 00Z TUESDAY. THE GENERAL STORY THROUGHOUT MY PERIOD IS A CONTINUATION FOR HOT TEMPERATURES AND A SLIGHT CHANCE FOR THUNDERSTORMS. AN UPPER LEVEL SHORTWAVE TROUGH MOVING THROUGH THE GREAT LAKES WILL PUSH A WEAK COLD FRONT INTO THE CENTRAL PLAINS ON TUESDAY. A FAIRLY STRONG 20 KNOT 850 HPA DOWNSLOPE FLOW WILL RESULT IN VERY HOT TEMPERATURES AHEAD OF THE FRONT. THESE INCREASING THICKNESS FIELDS AND RELATIVELY LOW ELEVATION ACROSS MY SOUTHEAST ZONES FAVOR THE HOTTEST TEMPERATURES WITH TEMPS PEAKING AROUND 110 DEG F TOWARDS MEDICINE LODGE. WE COULD SEE SOME THUNDERSTORMS, MAINLY ACROSS THE WEST SO HAVE BROAD BRUSHED THE REGION WITH 20-30 PERCENT POPS. THIS FRONTAL BOUNDARY STALLS AND REMAINS OVER KANSAS MIDWEEK ALTHOUGH THERE ARE SOME POSITION DIFFERENCES BETWEEN THE 30.12Z GFS/ECMWF. AS A RESULT, HAVE KEPT SLIGHT POPS IN THE GRIDS THROUGH MUCH OF NEXT WEEK MAINLY TO THE NORTH. AS THE BOUNDARY WASHES OUT, LEE TROUGHING COULD SPARK MORE CONVECTION ACROSS EASTERN COLORADO AND INTO WESTERN KANSAS BY THE END OF NEXT WEEK. TEMPERATURES WILL BE IN THE 98-103 DEG F RANGE FOR HIGHS AND 70S FOR LOWS. THIS IS STILL ABOVE NORMAL AS NORMAL HIGHS THIS TIME OF YEAR IS IN THE MID 90S. THE GOOD NEWS IS LOOKING AT THE END OF THE MODEL RUN PERIOD, THE ECMWF MAINTAINS ZONAL FLOW ACROSS THE CENTRAL UNITED STATES AND WITH LESS UPPER LEVEL RIDGING. SUCH A PATTERN COULD FAVOR MORE FREQUENT PASSAGES OF "COOL" FRONTS. THE GFS IS STRONGER WITH 500 HPA RIDGING SO TIME WILL TELL THIS FAR OUT IN THE FCST. -SUGDEN && .AVIATION... RECENT RUNS OF THE HRRR AND THE 30.12Z 4 KM WRF BREAK OUT SOME CONVECTION THIS AFTERNOON TOWARDS 23Z ALONG A STATIONARY BOUNDARY THAT IS BISECTING THE CWFA. WENT AHEAD AND PUT IN CB FOR KDDC AND KGCK IN THE 18Z TAFS. THINK KHYS WILL BE NORTH AND CLEAR OF BOUNDARY INDUCED STORMS. 30.18Z NAM IS ALSO SUGGESTION CONVECTION BUT LESS OF AN IMPACT TO KGCK. 00Z TAFS MIGHT REQUIRE SOME ADJUSTMENT DEPENDING ON CONVECTIVE/RADAR TRENDS. OTHERWISE, CIGS WILL BE VFR AND WINDS WILL BE OUT OF THE SE/S IN THE 8 TO 15 KNOT RANGE. -SUGDEN && .PRELIMINARY POINT TEMPS/POPS...
