AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE TOPEKA KS 258 PM CDT SUN MAY 27 2012 .DISCUSSION... TONIGHT...LITTLE CHANGE IN FORECAST THINKING AS LARGE UPPER TROUGH LIFTS INTO THE NORTHERN/CENTRAL PLAINS. HIGH RESOLUTION CONVECTIVE RESOLVING MEMBERS SHOW HIGH CONFIDENCE IN STORM INITIATION ALONG A DRYLINE/COLD FRONT BETWEEN 21-22Z IN WEST CENTRAL KANSAS...WELL WEST OF THE CWA. THUNDERSTORMS WILL RAPIDLY MATURE AND MAKE SLOW PROGRESS EASTWARD DURING THE REMAINDER OF THE AFTERNOON/EARLY EVENING HOURS. A FEW OF THESE STORMS MAY ENTER PORTIONS OF NORTH CENTRAL KANSAS BETWEEN 01-04Z. THESE STORMS MAY BE SEVERE...WITH LARGE HAIL AND DAMAGING OUTFLOW WINDS THE PRIMARY SEVERE WEATHER HAZARD. WITH RELATIVELY LARGE T-TD SPREADS DURING THE EVENING FOLLOWED BY NOCTURNAL BOUNDARY LAYER COOLING SHOULD MITIGATE TORNADO POTENTIAL IN MOST ACTIVITY. LARGE HAIL WILL BE MOST LIKELY WITH ANY SUSTAINED ISOLATED/SEMI-ISO CONVECTION DURING THE EVENING HOURS. AS STORMS EVOLVE...STRONG WIND GUSTS MAY OCCUR AS COLD POOLS BEGIN TO DOMINATE THE STORM-SCALE PROCESS. AS THE UPPER ASCENT MOVES RAPIDLY NORTHWARD TONIGHT...THUNDERSTORMS WILL GRADUALLY BECOME LESS NUMEROUS ALONG THE SOUTHERN END OF CONVECTION. THEREFORE CONSIDERABLE UNCERTAINTY EXISTS WITH REGARDS TO COVERAGE OF CONVECTION OVERNIGHT IN THE REMAINDER OF THE CWA. MOST OPERATIONAL GUIDANCE SHOWS LITTLE TO NO THUNDERSTORMS OVER THE CWA OVERNIGHT. WILL ACCOUNT FOR A FEW THUNDERSTORMS DUE TO SOME DEGREE OF LOCALIZED ASCENT FROM COLD POOL GENERATION AND THE ACTUAL FRONTAL BOUNDARY MOVING THROUGH A MODEST INSTABILITY FIELD...BUT WOULD NOT BE SURPRISED TO SEE MUCH OF NORTHEAST AND EAST CENTRAL KANSAS REMAINING DRY. LIKEWISE...SEVERE WEATHER IS MUCH MORE UNCERTAIN IN AREAS OUTSIDE OF NORTH CENTRAL KANSAS...ESPECIALLY WITH THE LATER ARRIVAL OF THE AFOREMENTIONED FOCI. MONDAY...A FEW ELEVATED EARLY MORNING STORMS MAY DEVELOP IN CLOSE PROXIMITY TO THE FRONTAL BOUNDARY OR OUTFLOW AND QUICKLY EXIT THE CWA BY MID MORNING. THE FRONT IS EXPECTED TO CLEAR THE CWA DURING THE AFTERNOON HOURS...ENDING ANY POTENTIAL FOR PRECIPITATION. EVEN THOUGH MUCH OF THE CWA WILL BE LOCATED NEAR OR BEHIND THE BOUNDARY DURING THE AFTERNOON...TEMPERATURES WILL STILL LIKELY BE ON THE WARM SIDE AS ONLY WEAK CAA ARRIVES LATE. EXPECT HIGHS ON MONDAY TO REACH THE MIDDLE TO UPPER 80S. BLAIR A BREAK FROM THE HEAT NEXT WEEK AS COOLER CANADIAN AIR CONTINUES TO FILTER INTO THE CENTRAL PLAINS TUESDAY AND WEDNESDAY. AN OUTSIDE CHANCE FOR A SHOWER OR THUNDERSTORM WEDNESDAY MORNING AS WAA RETURNS OVER THE FRONT INTO KANSAS. CHANCE FOR DAYTIME PRECIPITATION WEDNESDAY COMES FROM SHORTWAVE MOVING OUT OF THE NORTHERN ROCKIES WHICH HAS ABOUT 12 HOURS OF TIMING DIFFERENCE BETWEEN THE GFS AND NAM WITH NAM THE SLOWER LESS AMPLIFIED OF THE TWO. HIGHS IN THE LOWER 80S MONDAY COOL TO THE UPPER 70S WEDNESDAY. A REINFORCING SHOT OF COOL AIR BEHIND THE DEPARTING SHORTWAVE COULD LEAVE HIGHS IN THE 60S FOR THURSDAY TO NEAR 70 ON FRIDAY. SOUTHERLY SURFACE FLOW AND WEAK UPPER RIDGING ACROSS THE NORTHERN PLAINS RETURN FOR SATURDAY AND SUNDAY AND SHOULD BRING TEMPERATURES BACK INTO THE 80S. KEPT RAIN CHANCES FOR THE PASSING WAVE ON THURSDAY THEN A SLIGHT CHANCE FOR SATURDAY WITH WAA RETURNING AHEAD OF WARMER TEMPS. 67 && .AVIATION... VFR CONDITIONS CONTINUE THROUGH FORECAST PERIOD. STRONG SOUTHERLY WINDS NEAR AND ABOVE 20KTS SUSTAINED WANE TO AROUND 10KTS AS A FRONTAL PASSAGE VEERS TO THE SOUTHWEST BY 14Z AT KTOP/KFOE AND 09Z AT KMHK. LATEST HIGH RESOLUTION MODELS SHOW GREATER CONFIDENCE IN TSRA TRACKING NORTHEAST OVER CENTRAL KS DURING THE LATE AFTERNOON PERIOD. IT IS STILL POSSIBLE A THUNDERSTORM MAY NEAR KMHK AFT 07Z WITH LESSER CONFIDENCE FOR COVERAGE OF SH OR TSRA TO MAKE IT TO KTOP/KFOE. A STRONG LOW LEVEL JET AROUND 60 KTS WILL MIX DOWN AFTER 07Z WITH SFC WINDS VEERING TO SOUTHWEST MAY CREATE LLWS AFTER 07Z. BOWEN && .TOP WATCHES/WARNINGS/ADVISORIES... NONE. &&
