AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE NORMAN OK 319 PM CDT MON AUG 18 2014 .DISCUSSION... IN THE WAKE OF THIS MORNINGS OUTFLOW BOUNDARY AND DECAYING STORMS...THINGS HAVE REALLY HEATED UP. TRIPLE DIGITS WERE COMMON ACROSS MUCH OF WESTERN OKLAHOMA AND WESTERN NORTH TEXAS...WITH UPPER 90S ELSEWHERE. RECENTLY...VIS SATELLITE AND RADAR DEPICT ISOLATED SHOWERS/STORMS DEVELOPING FROM SOUTHWEST KANSAS INTO NORTHERN OKLAHOMA. STORMS MAY BECOME MORE SCATTERED THROUGH THE LATE AFTERNOON AND EARLY EVENING...PARTICULARLY ACROSS NORTHERN OKLAHOMA. STRONGER STORMS MAY PRODUCE GUSTY WINDS TO 40 OR 50 MPH...AND HEAVY RAINFALL. OTHERWISE...ACTIVITY SHOULD GENERALLY DIMINISH OVERNIGHT. THE WEATHER PATTERN OVER THE NEXT SEVERAL DAYS WILL GENERALLY BE MUCH THE SAME AS TODAY. HIGHS SHOULD RANGE FROM THE UPPER 90S TO LOW 100S BENEATH BROAD RIDGING. THESE TEMPERATURES COMBINED WITH FAIRLY HIGH SURFACE MOISTURE WILL LEAD TO HEAT INDICES IN THE 100 TO 105 DEGREE RANGE INTO THE WEEKEND. IF YOU HAVE OUTDOOR PLANS...MAKE SURE YOU DRINK PLENTY OF FLUIDS AND TAKE FREQUENT BREAKS. OTHERWISE...STAY INSIDE IF YOU CAN! GIVEN LACK OF SUBSTANTIAL UPPER FORCING AND NEGLIGIBLE SFC BOUNDARIES...WILL MAINTAIN SILENT POPS INTO THE WEEKEND...BUT AN ISOLATED STORM OR TWO COULD OCCUR ALMOST ANYWHERE GIVEN DAYTIME HEATING AND ABUNDANT MOISTURE. FROM THE WEEKEND INTO EARLY NEXT WEEK...LONG RANGE GUIDANCE CONTINUES TO SUGGEST THE LARGE SCALE RIDGE MAY FLATTEN IN RESPONSE TO SEVERAL UPPER WAVES/FRONTS MOVING ACROSS THE NORTHERN CONUS. THIS MAY EVENTUALLY ALLOW FOR A SOUTHERN PLAINS FRONTAL PASSAGE BY THE MIDDLE OF NEXT WEEK. SHOULD THIS OCCUR...SOME SLIGHTLY COOLER TEMPERATURES MAY BE ON THE WAY...ALONG WITH INCREASING RAIN CHANCES. && .PRELIMINARY POINT TEMPS/POPS...
