Area forecast discussion, Aug 3, 4:48 PM MST, 3 hours 5 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE GOODLAND KS 548 PM MDT TUE AUG 3 2010 .DISCUSSION... 251 PM MDT TUE AUG 3 2010 1630Z WATER VAPOR IMAGERY/RUC ANALYSIS INDICATED LARGE RIDGE AXIS IN PLACE ACROSS THE SOUTHERN US WITH MOISTURE PLUME EXTENDING AROUND WESTERN PERIPHERY AND ACROSS WESTERN CWA. MORNING RAOBS FROM AROUND THE AREA INDICATED ONLY SMALL CHANGES IN PW FIELD...WITH VALUES REMAINING AROUND 140 PERCENT OF NORMAL. 15Z SFC OBSERVATIONS INDICATED FRONTAL ZONE WHICH WAS DRAPED ACROSS AREA YESTERDAY HAD SHIFTED SOUTH AND WAS BETWEEN DDC AND P28. PRIMARY CONCERN FOR SHORT TERM WILL BE FLASH FLOODING/HEAVY RAIN POTENTIAL TONIGHT. TONIGHT...CONVECTIVE CHANCES HARD TO PIN DOWN AT THIS POINT AS LARGE SCALE FORCING FOR ASCENT APPEARS TO BE FAIRLY MINOR AND CONVECTION WILL LIKELY BE DRIVEN MAINLY BY SMALL SCALE PROCESSES. WITH THIS IN MIND...AM HESITANT TO JUMP ON ANY MODEL SOLUTION TO QUICKLY AND PLAN ON WATCHING THINGS DURING THE AFTERNOON BEFORE MAKING A FINAL CALL...WITH A CONFLUENT AREA NEAR YUMA COUNTY AND CU FIELD WEST OF KSPD BOTH POTENTIAL INITIATION AREAS. MCS PROPAGATION VECTORS WOULD SUGGEST BOTH AREAS COULD IMPACT THE CWA. IF THUNDERSTORMS CAN DEVELOP...HIGH FREEZING LEVELS AND PW'S WOULD SUPPORT THREAT FOR HEAVY RAIN. GIVEN AREAS THAT RECEIVED IN EXCESS OF 3 INCHES LAST NIGHT...MAY NEED A FLASH FLOOD WATCH IF CONVECTIVE INITIATION LOOKS IMMANENT. 20Z SFC AND SAT OBSERVATIONS NOT REALLY CLEARING UP SITUATION MUCH...WITH LARGE AREA OF CU FORMING ACROSS NORTHERN CWA...WHILE LATEST MESO ANALYSIS SUGGESTS STRONGEST INSTABILITY EXISTS TO THE SOUTH...BUT WITH FEW CU AND GIVEN CINH FIELDS ACROSS THIS AREA NOT CONFIDENT THAT CONVECTION NEAR SPD WILL WORK ITS WAY UP HERE. WHILE TEMPS ARE COOLER TO THE NORTH...70 TDS APPEAR TO BE WORKING THERE WAY WESTWARD WITH TDS STEADILY CLIMBING THROUGH MUCH OF THE DAY. WITH ALL THINGS BEING EQUAL AND LIMITED LARGE SCALE FORCING...WOULD THINK THAT ANY CONVECTION THAT FORMS WOULD GENERALLY MOVE ALONG THIS MOISTURE AXIS AND WILL WEIGHT POP/QPF IN THIS AREA. WITH CONCERNS ABOUT CONVECTIVE COVERAGE AND POSSIBLE STRUGGLES WITH INITIATION AM HESITANT TO ISSUE A VERY LARGE WATCH...BUT THINK WITH THE LARGE AREA OF HEAVY RAIN THAT OCCURRED LAST NIGHT IN KIT CARSON COUNTY...THE THREAT OF ADDITIONAL RAINFALL WARRANTS A WATCH. TOMORROW-TOMORROW NIGHT...WEAK SHORT WAVE TROUGH...APPARENT ON 1.5 PVU FIELDS WILL CONTINUE TO SLOWLY ADVECT ACROSS THE AREA THROUGH THE DAY...WITH DIV Q FIELDS SUGGESTING LARGE SCALE FORCING FOR ASCENT INCREASES THROUGH THE DAY. NOT SURE HOW MUCH CONVECTIVE CHANCES THERE WILL BE IN THE MORNING AS POTENTIAL FOR CWA TO BE SOMEWHAT STABILIZED BY OVERNIGHT CONVECTION...ALTHOUGH WITH WEAK TROUGH LIFTING OVER THE AREA MORNING CONVECTION NOT UNREALISTIC. WITH FRONT WELL TO THE SOUTH OF THE AREA MUCH OF THE CWA WILL BE UNDER THE INFLUENCE OF LIGHT UPSLOPE FLOW. THE WEAK OROGRAPHIC FORCING ALONG WITH SOME BACKGROUND ASCENT SHOULD BE ENOUGH TO SET OF A FEW STORMS...BUT PLAN ON KEEPING THE HIGHEST POPS NEAR HIGHER TERRAIN. WITH WEAK FLOW ALOFT AND A FAIRLY DEEP WARM LAYER...HEAVY RAIN THREAT WILL CONTINUE THROUGH THE PERIOD. THURS-FRIDAY AFTERNOON... H5 RIDGE AXIS WILL SLOWLY BEGIN TO AMPLIFY AND SHIFT EAST DURING THE PERIOD...BUT WITH OVERALL SFC PATTERN NOT CHANGING EXPECT TO SEE ANOTHER ROUND OF LATE AFTERNOON AND EVENING STORMS DURING THE PERIOD. AS RIDGE AMPLIFIES CINH MAY BECOME MORE OF A FACTOR...ESPECIALLY ON FRIDAY BUT WITH AS MUCH UNCERTAINTY THAT EXISTS LEADING TO THIS POINT IN THE FORECAST THINK KEEPING THUNDER CHANCES THROUGH THE PERIOD LOOKS REASONABLE. IN THE EXTENDED...AN AMPLIFYING RIDGE APPEARS TO BE THE MAIN SYNOPTIC SCALE FEATURE THROUGH THE EXTEND PERIOD. FOR THE MOST PART...MEDIUM RANGE MODELS IN REASONABLY GOOD AGREEMENT WITH THIS FEATURE ACROSS THE GLD CWA...ALTHOUGH DIFFERENCES IN AMPLITUDE WITH RESPECT TO RIDGE AND TROUGH AXIS OFF THE WEST COAST DEVELOP THROUGHOUT THE PERIOD. IN GENERAL...THINK A COMPROMISE BETWEEN ECMWF/GFS AND GEFS MEAN DATA A REASONABLE STARTING POINT FOR THIS FORECAST. WHILE LARGE SCALE PATTERN APPEAR SIMILAR BETWEEN ECMWF AND GFS...TEMPERATURE FIELDS VARY GREATLY WITH DIFFERENCES WITH POSITION OF FRONTAL ZONE THAT WILL DRIFT BACK AND FORTH ACROSS THE AREA. GEFS MEAN H850 TEMPS ARE RATHER WARM AND LEANED ON THE WARMER SIDE OF THINGS FOR TEMPS. WILL KEEP SOME LOW EVENING POPS THROUGH THE PERIOD AS CWA REMAINS ON FRINGE OF RIDGE AND FRONTAL ZONE MAY PROVIDE SOME FOCUS FOR PRECIPITATION THROUGH THE PERIOD. JRM && .AVIATION... 540 PM MDT TUE AUG 3 2010 FOR THE 00Z TAFS...COMPLEX AND UNCERTAIN TAFS ONCE AGAIN. PRETTY SURE THE THUNDERSTORMS WILL COME BUT NOT SURE FROM WHICH DIRECTION AND WHEN WITH A NUMBER OF POSSIBILITIES. PRETTY GOOD CU AND TOWERING CU DEVELOPMENT AT THIS TIME BUT BELIEVE MAIN CHANCE OF THUNDERSTORMS WILL WAIT TO MOVE IN FROM THE WEST AND NORTHWEST DURING THE LATE EVENING AND OVERNIGHT HOURS. AT THIS TIME CHOSE TO HANDLE WITH VCTS BUT AS STATED BEFORE...IF ONE OF THESE THUNDERSTORMS AFFECTS THE TAF...IT COULD CREATE IFR CONDITIONS. ONCE BECOME CERTAIN OF THIS...WILL UPDATE FOR IT. POSSIBLE THAT ONCE THE THUNDERSTORMS END...STRATUS AND FOG COULD DEVELOP AND AFFECT THE KMCK TAF THROUGH THE MID MORNING HOURS. THERE WILL BE ANOTHER CHANCE OF THUNDERSTORMS DURING THE LATE AFTERNOON HOURS TOMORROW BUT CHOSE TO NOT MENTION ANYTHING SINCE TOWARD THE END OF THE PERIOD AND THE HIGH DEGREE OF UNCERTAINTY. BULLER && .GLD WATCHES/WARNINGS/ADVISORIES... KS...NONE. NE...NONE. CO...FLASH FLOOD WATCH UNTIL 5 AM MDT WEDNESDAY FOR COZ091. &&
