AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE GOODLAND KS 523 PM MDT MON AUG 2 2010 .DISCUSSION... 308 PM MDT MON AUG 2 2010 IN THE BIG PICTURE...THE HUDSON BAY LOW IS FORECAST TO DEEPEN DURING THE WEEK AS SEVERAL STRONG SHORT WAVE TROUGHS DROP INTO SOUTHEAST CANADA. THE IMPACT ON THIS AREA WILL BE THE LOCATION AND STRENGTH OF THE UPPER HIGH...NOW LOCATED OVER NORTHERN MISSISSIPPI. MODELS MOVE THIS UPPER HIGH INTO WEST TEXAS BY LATE THURSDAY AFTER WHICH TIME IT WILL TEND TO RIDGE NORTH OVER THE WEEKEND. WITH THE UPPER HIGH LOCATED OVER THE SOUTHERN STATES THROUGH THURSDAY...ENOUGH WESTERLY FLOW ALOFT WILL EXIST OVER OUR AREA TO KEEP PRECIPITATION CHANCES ALIVE AS SEVERAL WEAK SHORT WAVE TROUGHS MOVE THROUGH THE FLOW. THE ULTIMATE PLACEMENT AND INTENSITY OF PRECIPITATION WILL DEPEND ON THE LOCATION OF A SURFACE FRONT TO OUR SOUTH...AS WELL AS THE STRENGTH OF BOUNDARY LAYER UPSLOPE FLOW AND MOISTURE AVAILABILITY. THUS...THE CURRENT FORECAST REFLECTS BEST PRECIPITATION POTENTIAL TONIGHT THROUGH THURSDAY ALONG WITH COOLER AFTERNOON MAX TEMPS...WITH LESSER PRECIPITATION POTENTIAL FRIDAY-MONDAY ACCOMPANIED BY WARMER TEMPS. IN THE NEAR TERM...CONGESTED CUMULUS ARE FORMING ON THE PALMER DIVIDE AND IN THE SURFACE WIND CONVERGENT ZONE SOUTH AND SOUTHEAST OF GOODLAND. GUIDANCE SUGGESTS THE BEST POTENTIAL FOR PRECIPITATION TONIGHT WILL BE IN OUR WEST AND NORTH COUNTIES AS CONVECTION DEVELOPS OVER SOUTHEAST COLORADO LATER THIS AFTERNOON AND MOVES NORTHEAST AFTER 00Z. THIS SEEMS TO CORRELATE WITH AN UPPER IMPULSE LIFTING NORTH-NORTHEAST FROM THE MAIN TROUGH TO OUR WEST. NOT TOO CONVINCED THE CURRENT CU FIELD SOUTH OF GLD OR THE FIELD RIGHT NOW NEAR THE COLORADO-KANSAS BORDER WILL GO ON TO PRODUCE MUCH IN THE WAY OF TSRA THIS EVENING. KEPT CHANCE POPS GOING TUESDAY AND TUESDAY NIGHT AS THE UPPER SHORT WAVE TROUGH INITIATING THIS EVENINGS CONVECTION MOVES SLOWLY ACROSS THE AREA TOMORROW. PRECIPITABLE WATER IS FORECAST TO CONTINUE HIGH WITH VALUES AROUND 1.5 INCHES. GIVEN THESE VALUES AND FAIRLY WEAK UPPER FLOW...FEEL THE POTENTIAL EXISTS FOR LOCALIZED HEAVY RAIN EVENTS NEXT COUPLE DAYS. THE COMBINATION OF CLOUD COVER AND OUTFLOW FROM CONVECTION WILL ACT TO GRADUALLY PUSH A SURFACE FRONT INTO SOUTHERN KANSAS BY TOMORROW AFTERNOON. HIGH TEMPERATURES TUESDAY WILL BE ABOUT 5-10 DEGREES COOLER THAN TODAY...AND ON WEDNESDAY AND THURSDAY WILL HOLD IN THE 80S FOR THE MOST PART WITH COOLER AND MOIST NORTHEAST SURFACE FLOW DOMINATING. IN THE LONGER TERM...DID NOT MAKE MANY CHANGES. KEPT SILENT POPS IN FOR THE FRIDAY TO MONDAY PERIOD ALONG WITH WARMING TEMPERATURES AS THE UPPER HIGH EXERTS A STRONGER INFLUENCE ON THE AREA. 99 && .AVIATION... 523 PM MDT MON AUG 2 2010 FOR THE 00Z TAFS...THUNDERSTORMS HAVE INITIATED IN EASTERN COLORADO ALONG A SURFACE TROUGH AND MORE ISOLATED THUNDERSTORMS ARE POPPING UP IN NORTHWEST KANSAS. COLORADO WILL LIKELY BE THE MORE ACTIVE LOCATION TONIGHT...AND SOME OF THOSE STORMS COULD IMPACT KGLD WITH BRIEFLY LOWERED CEILINGS AND VISIBILITY IF THEY WERE TO MOVE DIRECTLY OVER THE AIRPORT...BUT APPEARS THAT IS SEVERAL HOURS AWAY BASED ON RADAR TRENDS. AT KMCK...THUNDERSTORM CHANCES APPEAR SLIM BUT CANNOT COMPLETELY RULE ONE OUT DURING THE OVERNIGHT HOURS. KMCK COULD SEE SOME BRIEF FLIGHT CATEGORY REDUCTIONS DUE TO FOG TOWARDS DAWN ON TUESDAY. 024 && .GLD WATCHES/WARNINGS/ADVISORIES... KS...NONE. NE...NONE. CO...NONE. &&
