Area forecast discussion, Aug 1, 3:59 PM MST, 1 hour 1 minute before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE GOODLAND KS 459 PM MDT THU AUG 1 2013 .SHORT TERM...(THIS AFTERNOON THROUGH FRIDAY) ISSUED AT 1127 AM MDT THU AUG 1 2013 SCATTERED AFTERNOON AND EVENING THUNDERSTORMS WILL DEVELOP ONCE AGAIN TODAY WITH THE LATEST SHORTWAVE DISTURBANCE MOVING OUT OF THE CENTRAL ROCKIES. NORTHERN SECTIONS OF THE AREA...PARTICULARLY SOUTHWEST NEBRASKA...WILL BE THE FAVORED LOCATION...WHICH IS ALSO WHERE THE BEST DEEP LAYER SHEAR AND INSTABILITY WILL RESIDE. A FEW SEVERE STORMS WILL BE POSSIBLE WITH LARGE HAIL AND DAMAGING WINDS THROUGH ABOUT MIDNIGHT BEFORE WINDING DOWN. FRIDAY...THE SURFACE TROUGH WILL MOVE EAST AND BE LOCATED NEAR A MCCOOK TO GOVE LINE BY 21Z. WEST OF THE TROUGH WILL BE WESTERLY SURFACE WINDS AND LOWER DEW POINTS...WITH ONLY WEAK INSTABILITY FORECAST. THE TROUGH WILL CONTINUE EAST AND CLEAR THE FORECAST AREA BY 00Z. ALTHOUGH THERE MIGHT BE A WEAK SHORTWAVE TROUGH TOPPING THE RIDGE AXIS...500MB HEIGHTS ARE RISING. THE COMBINATION OF POOR MOISTURE AND WEAK FORCING WILL SUPPRESS MOST IF NOT ALL CONVECTION THROUGH THE AFTERNOON SO KEPT POPS AT 10. A DOWNSLOPE WIND COMPONENT AND LACK OF CLOUD COVER WILL ALLOW TEMPERATURES TO RISE INTO THE MIDDLE TO UPPER 90S. .LONG TERM...(FRIDAY NIGHT THROUGH THURSDAY) ISSUED AT 248 PM MDT THU AUG 1 2013 FRIDAY NIGHT-SATURDAY NIGHT...A COLD FRONT WILL DROP SOUTH ACROSS THE REGION FRIDAY NIGHT STALLING ALONG THE FRONT RANGE AND ACROSS SOUTHERN KANSAS. WITH GOOD INSTABILITY AND SHEER OVERNIGHT WE COULD SEE A PERIOD OF STRONG THUNDERSTORMS OVERNIGHT...WITH BEST INSTABILITY AND SHEER TRANSITIONING SOUTHWARD BY 12-15Z. A STRONG VORTICITY MAX IS ADVERTISED BY GFS/ECMWF/NAM TO PASS ACROSS KANSAS SATURDAY AFTERNOON AND SATURDAY NIGHT WHICH COULD SUPPORT/ENHANCE COVERAGE OF THUNDERSTORMS. BEST CHANCE IN OUR CWA WILL GENERALLY BE SOUTH OF I-70 WHERE BETTER LARGE SCALE ASCENT IS ADVERTISED...AND BETTER CONVERGENCE NEAR FRONTAL ZONE. HOWEVER...WITH GOOD ISENTROPIC SUPPORT/ELEVATED INSTABILITY...AND DEEP MOIST FLOW NORTH OF THE FRONT WE COULD SEE A DECENT SHOT OF SHOWERS/THUNDERSTORMS ACROSS MUCH OF OUR CWA. SHEER AND INSTABILITY WILL BE MARGINAL NORTH OF FRONT OVER OUR CWA...THOUGH THERE COULD STILL BE ENOUGH FOR A FEW STRONG STORMS ESPECIALLY NEAR FRONTAL ZONE. WITH COOLER AIR MASS (H85 TEMPS 16-20C) AND THICK CLOUD COVER IN PLACE WE MAY SEE HIGHS STRUGGLE TO MAKE IT OUT OF THE UPPER 60S/LOW 70S ON SATURDAY. I UNDERCUT MOST GUIDANCE AND CONSERVATIVELY LOWERED TEMPS TO UPPER 70S (NORTH) TO MID 80S (SOUTH). SUNDAY-SUNDAY NIGHT...WITH FRONTAL ZONE STILL LINGERING NEAR OUR CWA AND MOIST FLOW NORTH OF THIS FEATURE WE COULD CONTINUE TO SEE THICK CLOUDS AND PRECIP CHANCES LINGERING. WITHOUT UPPER LEVEL FORCING...COVERAGE WILL LIKELY BE LIMITED AND BEST SUPPORT FOR THUNDERSTORMS WILL BE ALONG TERRAIN IN THE WEST. AT THE SAME TIME CONSIDERING THE PATTERN ACROSS MOST OF THE CWA (DEEP MOIST FLOW/ELEVATED INSTABILITY)...I DIDNT WANT TO MAKE FORECAST COMPLETELY DRY I KEPT SLIGHT CHANCE POPS IN PLACE FURTHER EAST...AND CHANCE POPS IN THE FAR WEST. MODELS ARE ACTUALLY HINTING AT THE FRONT BEGINNING TO SHIFT EAST BY SUNDAY AFTERNOON...WHICH COULD ALLOW SKIES TO BEGIN TO CLEAR AND TEMPS TO MODERATE ALOFT. I KEPT HIGHS BELOW NORMAL FOR MOST LOCATIONS (LOW- MID 80S)...HOWEVER I DID BUMP TEMPS CLOSER TO SEASONAL NORMALS IN THE WEST. MONDAY-THURSDAY...WESTERLY FLOW IS EXPECTED TO PERSIST THROUGH THE EXTENDED PERIOD WITH BROAD RIDGE ACROSS THE SOUTHERN PLAINS AND LARGE SCALE UPPER LOW OVER THE NORTHEASTERN US. AMPLIFIED RIDGE AXIS WILL SHIFT WEST AND ALLOW STORM TRACK TO SHIFT FURTHER SOUTH FROM NORTHERN PLAINS. THIS WILL SUPPORT A VERY ACTIVE PATTERN WITH EMBEDDED SHORTWAVE TROUGHS AND VORTICITY MAX ROUNDING THE WESTERN EXTENT OF THE UPPER LOW...AND THROUGH THE MEAN FLOW OVER WESTERN KANSAS. IT IS VERY DIFFICULT TO PIN DOWN THESE FEATURES AND ADD DETAIL WITH VARIANCE BETWEEN MODELS ON TIMING/LOCATION AND SMALLER SCALE BOUNDARIES WHICH WOULD ACT TO ENHANCE OR INITIATE SHOWERS/THUNDERSTORMS...WHICH ADDS AN ELEMENT OF UNCERTAINTY TO EVERY DAY NEXT WEEK. I WAS COMFORTABLE KEEPING POPS IN EVERY PERIOD WHICH SUPPORTS THIS ACTIVE PATTERN...HOWEVER I CAPPED POPS IN THE CHANCE CATEGORY DUE TO THE MENTIONED UNCERTAINTIES. TEMPERATURES IN THIS PATTERN SHOULD ALSO TREND TOWARDS COOLER SOLUTIONS WITH BACKDOOR COLD FRONTS LIKELY REINFORCING COOLER AIR MASS. GUIDANCE CURRENTLY IS HOLDING TEMPERATURES NEAR NORMAL (UPPER 80S) ON MONDAY...HOWEVER THIS MIGHT BE TOO COOL. BY THE MIDDLE OF NEXT WEEK WE WILL LIKELY SEE HIGHS 10-15F BELOW NORMAL IN 70S TO LOW 80S. && .AVIATION...(FOR THE 00Z TAFS THROUGH 00Z FRIDAY EVENING) ISSUED AT 458 PM MDT THU AUG 1 2013 THUNDERSTORMS ARE MOVING ACROSS EASTERN COLORADO AND NORTH CENTRAL NEBRASKA. A FEW CELLS ALSO DEVELOPED JUST EAST OF KGLD. ALTHOUGH THERE IS A DECENT CHANCE THAT STORMS WILL MOVE ACROSS BOTH KGLD/KMCK... IT IS NOT A CERTAINTY. THE BEST CHANCE WILL BE AT KGLD...AND WILL ADD A TEMPO GROUP FOR THUNDERSTORMS THERE BETWEEN 00-04Z AS CELLS CONTINUE TO DEVELOP NEAR THE SITE. WILL JUST MENTION VCTS AT KMCK. CONVECTION SHOULD DECREASE AFTER 06Z. EXPECT VFR CONDITIONS AFTER 06Z...THOUGH CONVECTION WILL LIKELY DEVELOP FRIDAY AFTERNOON AFTER 21Z. && .GLD WATCHES/WARNINGS/ADVISORIES... KS...NONE. CO...NONE.
