A prolonged 3 day period of heat indices in the 106 to 114 degree range occurred across much of Northeast Kansas between Monday August 9th and Friday August 13th. An excessive heat watch was issued on Friday August 6th that outlined what was expected to occur during the work week. No fatalities were reported and no information regarding the presence or number of any heat related illnesses were noted during the event. The heat finally ended when a cold front moved through the area later Friday August 13th into Saturday August 14th.

A BROAD UPPER LEVEL RIDGE WILL CONTINUE TO HOLD NEARLY STATIONARY ACROSS THE SOUTHERN PLAINS AND NORTHERN GULF STATES THROUGH WEDNESDAY. THE CORE OF THE 925MB LLJ EARLY MORNING WAS NOTED FROM SOUTH CENTRAL KS NORTHEAST ACROSS THE WESTERN CWA. WEAK ISENTROPIC LIFT BETWEEN THE 900-850MB LEVEL WAS ALLOWING SOME MOIST PARCELS TO REACH THEIR LFC..AS A RESULT THERE MAY BE AN ISOLATED SHOWER OR THUNDERSTORM THROUGH 14Z ACROSS THE CWA. THE MIXED BOUNDARY LAYER SHOULD DEEPEN ENOUGH BY 15Z TO BRING AN END TO ANY ISOLATED ELEVATED THUNDERSTORMS. EXPECT HOT AND HUMID CONDITIONS TO CONTINUE TODAY THROUGH AT LEAST WEDNESDAY. HIGHS WILL REACH TO AROUND 100 ACROSS MOST OF THE CWA. DEWPOINTS ACROSS THE EASTERN COUNTIES OF THE CWA WILL HOLD IN THE LOWER TO POSSIBLY MIDDLE 70S CAUSING HEAT INDICES TO REACH 108 TO 114 DEGREES. SLIGHTLY DEEPER MIXING ACROSS THE WESTERN COUNTIES MAY CAUSE AFTERNOON DEWPOINTS TO DROP INTO THE UPPER 60S. HOWEVER...HEAT INDICES SHOULD STILL REACH TO AROUND 105 DEGREES THIS AFTERNOON THROUGH WEDNESDAY AFTERNOON. SINCE NORTH CENTRAL KS WILL HAVE AT LEAST FOUR CONSECUTIVE DAYS WITH HEAT INDICES AT OR ABOVE 105 DEGREES...I HAVE DECIDED TO EXPAND THE EXCESSIVE HEAT WARNING ACROSS THE ENTIRE CWA THROUGH EARLY WEDNESDAY EVENING. DURING THE AFTERNOON HOURS THERE MAY BE AN ISOLATED PULSE STORM...MAINLY ACROSS THE WESTERN AND NORTHERN COUNTIES OF THE CWA. THURSDAY THROUGH SUNDAY...THE EC FORECAST A H5 TROUGH TO AMPLIFY ACROSS THE NORTHERN PLAINS AND MIDWEST THURSDAY MORNING. THIS MAY CAUSE A WEAK FRONT TO PUSH SOUTHWEST ACROSS THE NORTHERN HALF OF THE CWA THURSDAY MORNING. HIGHS ACROSS THE NORTHERN COUNTIES OF THE CWA MAY COOL INTO THE LOWER TO MID 90S...THOUGH DEWPOINTS MAY BE HIGHER NORTH OF THE FRONT. THERE MAY BE ENOUGH SFC CONVERGENCE ALONG THE SFC FRONT FOR ISOLATED THUNDERSTORMS THURSDAY AFTERNOON ACROSS THE NORTHERN COUNTIES. ALONG AND SOUTH OF I-70...THE HOT AND HUMID CONDITIONS MAY CONTINUE ON THURSDAY AND EXTEND THROUGH SATURDAY AFTERNOON. THE NEXT SHIFT MAY HAVE TO EXTEND THE EXCESSIVE HEAD ADVISORY SOUTH OF I-70 THROUGH SATURDAY AFTERNOON. BOTH THE EC AND GFS SHOW A MORE AMPLIFIED H5 TROUGH MOVING EAST ACROSS THE NORTHERN AND CENTRAL PLAINS SATURDAY AND SATURDAY NIGHT. THIS WILL CAUSE A COLD FRONT TO PUSH SOUTHWARD ACROSS THE CWA LATE SATURDAY AFTERNOON. THE FRONT WILL BECOME STATIONARY ACROSS EXTREME SOUTHERN KS BY SUNDAY MORNING. WE MAY SEE A CHANCE FOR SHOWERS AND THUNDERSTORMS ACROSS THE NORTHERN COUNTIES OF THE CWA SATURDAY AFTERNOON AHEAD OF THE SFC COLD FRONT...AND ACROSS THE REMAINDER OF THE AREA SATURDAY NIGHT. WE MAY SEE A ONE DAY BREAK IN THE HEAT ON SUNDAY WITH HIGHS ONLY REACHING THE UPPER 80S TO LOWER 90S. GARGAN && .TOP WATCHES/WARNINGS/ADVISORIES...EXCESSIVE HEAT WARNING UNTIL 8 PM WEDNESDAY FOR KSZ008-KSZ009- KSZ010-KSZ011-KSZ012-KSZ020-KSZ021-KSZ022-KSZ023-KSZ024-KSZ026- KSZ034-KSZ035-KSZ036-KSZ037-KSZ038-KSZ039-KSZ040-KSZ054-KSZ055- KSZ056-KSZ058-KSZ059. && 63
