Area forecast discussion, Aug 19, 9:45 PM CDT, 10 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE TOPEKA KS 945 PM CDT FRI AUG 19 2011 .UPDATE... ...UPDATED FOR CURRENT TRENDS AND INCREASING FLASH FLOOD POTENTIAL... LATEST OBSERVATIONS CONTINUE TO SUPPORT A HEAVY RAIN THREAT ACROSS THE AREA TONIGHT. OBSERVATIONS AND NEW SHORT TERM MODEL GUIDANCE AS WELL AS THE 00 UTC NAM ALSO SUPPORT THIS HEAVY RAIN POTENTIAL. THE THREAT APPEARS TO BE AMPLIFIED ACROSS NORTHEAST KANSAS... COINCIDENTALLY IN MUCH OF THE SAME AREA THAT RECEIVED 1 TO 2 INCHES OF HEAVY RAIN LAST NIGHT. AN INITIAL LINE OF CONVECTION ACROSS SOUTHEAST NEBRASKA WILL BUILD SOUTH WITH SOME MINOR BACKBUILDING POSSIBLE ACROSS EXTREME NORTHERN KANSAS THROUGH 05Z. WILL THEN EXPECT CONVERGENCE IN THE LOWER LEVELS TO BE MAXIMIZED BETWEEN 04Z AND 12Z NEAR AND JUST NORTH OF INTERSTATE 70 WHILE THE SHORT WAVE TROUGH ALOFT SLOWLY MAKES ITS WAY TO THE EAST. MOISTURE CONTENT WILL INCREASE INTO NORTHEAST KANSAS PRIOR TO THAT TIME. ALL IN ALL...PEAK RAINFALL RATES OF 1 TO 2 INCHES PER HOUR CAN BE EXPECTED WITH THE HEAVIEST STORMS...WITH THE BEST CHANCE FOR MORE PROLONGED TSTORM ACTIVITY TO AFFECT SATURATED GROUNDS WITHIN THE FLASH FLOOD WATCH AREA. BARJENBRUCH && .DISCUSSION... TONIGHT-SATURDAY: ANOTHER ROUND OF THUNDERSTORMS ARE EXPECTED BY MID EVENING INTO THE OVERNIGHT HOURS ACROSS THE CWA. AS OF EARLY THIS AFTERNOON...FINE LINE RADAR AND SURFACE MESONET OBSERVATIONS SHOWED A NW-SE ORIENTED FRONTAL BOUNDARY LOCATED OVER THE FAR SOUTHWESTERN CWA DELINEATING COOLER/MOIST CONDITIONS TO THE NORTH AND VERY HOT SFC TEMPERATURES TO THE SOUTH. AN UPPER DISTURBANCE WAS APPROACHING THE HIGH PLAINS...WITH CONVECTION NOW DEVELOPING OVER PARTS OF SW KANSAS AND SE COLORADO. THIS SFC BOUNDARY WILL DRIFT SOUTHWARD THROUGH TONIGHT AS THE UPPER WAVE MOVES ACROSS THE CENTRAL PLAINS. THE ONGOING CONVECTION IS PARTIALLY IN RESPONSE TO THE UPPER WAVE...AND ANTICIPATE THIS REGION OF ACTIVITY TO EXPAND IN COVERAGE AS IT MOVES NORTHEASTWARD ACROSS CENTRAL/NORTHERN KANSAS...MAINLY NORTH OF THE SFC BOUNDARY. SOME OF THIS ACTIVITY DURING THE EVENING MAY BECOME ROBUST...WITH THE STRONGEST ACTIVITY INITIALLY RESIDING OVER THE NORTHWEST HALF OF THE CWA. FURTHER CONCENTRATION OF CONVECTION OVER SE NEBRASKA INTO FAR NORTHERN KANSAS MAY EVOLVE INTO A COMPLEX...WITH OUTFLOW PROPAGATING THE SYSTEM MORE TO THE EAST OR SOUTHEAST BACK INTO PORTIONS OF THE CWA. THEREFORE...THE HIGHEST PROBABILITY OF CONVECTION FROM 00Z- 12Z WILL BE LOCATED ALONG AND NORTH OF INTERSTATE 70. OVERALL SHEAR/INSTABILITY LOWER THAN LAST NIGHTS EVENT...WITH THE MOST PROBABLE WINDOW OF OPPORTUNITY FOR SEVERE WEATHER PRIOR TO 08Z...GENERALLY NORTHWEST OF LINE FROM HOLTON TO ABILENE. THE MAIN SEVERE WEATHER THREAT WILL BE STRONG WINDS UP TO 60 MPH. ADDITIONALLY...LOCALIZED FLOODING MAY OCCUR IN THE MOST ROBUST ACTIVITY OVER PREVIOUSLY WET GROUNDS. CHANCES FOR ELEVATED THUNDERSTORMS/SHOWERS WILL CONTINUE THROUGH AT LEAST THE FIRST HALF OF SATURDAY BEFORE THE UPPER WAVE DEPARTS AND HIGH PRESSURE BEGINS TO BUILD IN FROM THE NORTH. LOWS TONIGHT WILL FALL INTO THE UPPER 60S TO LOWER 70S...WITH HIGHS ON SATURDAY ONLY REMAINING IN THE 80S WITH AMPLE CLOUD COVER AND PRECIPITATION EXPECTED. BLAIR PRECIP CHANCES DECREASE INTO THE EVENING HOURS SATURDAY NIGHT AS THE HIGH PUSHES IN AND THE FRONT MOVES TO THE SOUTH. OVERNIGHT LOWS IN THE 60S SHOULD BECOME HIGHS IN THE 80S SUNDAY WITH SOUTHEAST WINDS. SLIGHT CHANCES FOR PRECIP ON MONDAY AS LOW LEVEL JET RETURNS OVER THE FRONT AND ACROSS EASTERN KANSAS. CLIPPER SHORTWAVE TROF MOVING OUT OF THE UPPER MIDWEST MAY TRACK TO THE EAST OF THE STATE BUT WORTH LEAVING SLIGHT CHANCES AGAIN FOR TUESDAY. STRONGER FRONT MOVES IN BEHIND TROF PASSAGE ON WEDNESDAY AND WAS ABLE TO DIMINISH POP CHANCES WEDNESDAY DURING THE DAY THROUGH FRIDAY. STRONG RIDGE BUILDS ALOFT OVER COOLER SURFACE HIGH THAT SHIFTS INTO THE EAST COAST. HIGHS END OF THE WEEK MAY BE ABLE TO COOL INTO THE MID 80S. 67 && .AVIATION... VFR CONDITIONS EXPECTED FOR THE NEXT FEW HOURS BEFORE THUNDERSTORMS MOVE INTO THE TERMINALS DURING THE OVERNIGHT HOURS. MVFR CONDITIONS WILL BE POSSIBLE IN THE STRONGER STORMS OVERNIGHT. BEST CHANCES FOR MVFR CONDITIONS APPEAR TO BE IN THE 06-10Z TIME FRAME. CONDITIONS SHOULD IMPROVE TOWARDS DAYLIGHT BUT SHOWERS ARE EXPECTED TO LINGER INTO THE DAY TOMORROW. ANDERSON && .TOP WATCHES/WARNINGS/ADVISORIES... FLASH FLOOD WATCH THROUGH SATURDAY MORNING FOR KSZ011-012-023- 024-026-039-040. &&
