Area forecast discussion, Apr 23, 12:21 PM CDT, 2 hours 51 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE HASTINGS NE 1221 PM CDT WED APR 23 2008 .AVIATION...18Z TAF. CLOUDS ALREADY SPREADING INTO THE KGRI TERMINAL AREA. SOUTH WINDS WILL ALLOW FOR ADDITIONAL LOW LEVEL MOISTURE TO STREAM INTO THE AREA AND THEREFORE LOWER MVFR CEILINGS WILL SPREAD INTO THE AREA LATER TONIGHT. THERE IS A SMALL CHANCE FOR SOME THUNDERSTORMS IN THE VICINITY BUT DO NOT REALLY EXPECT THERE TO BE A LARGE CHANCE SO HAVE SOME THUNDERSTORMS IN THE VICINITY AND EXPECT THAT WILL COVER IT FOR THIS EVENING. && .PREV DISCUSSION... /ISSUED 351 AM CDT WED APR 23 2008/ DISCUSSION...FOCUS REMAINS ON CONVECTION THE NEXT COUPLE OF DAYS. THE SURFACE RIDGE AXIS HAS SHIFTED EAST OF OUR REGION AND WINDS IN THE RETURN FLOW ARE GRADUALLY COMING AROUND TO THE SOUTH AND SOUTHEAST. THE GOOD MOISTURE IS STILL TO OUR SOUTH ACROSS OKLAHOMA ATTM AND WILL BE A BIT SLOWER TO WORK ITS WAY NORTHWARD THIS MORNING...BUT NONETHELESS WILL STILL INCREASE THROUGHOUT THE DAY. THE SOUTHWESTERLY FLOW ALOFT ENHANCES DURING THE DAY AND SHORTWAVE ENERGY LIFTS NORTHEAST FROM THE SOUTHERN PLAINS. WITH THE INCREASE IN MOISTURE AND HEATING DURING THE DAY...INSTABILITY ALSO INCREASES WITH MODEL PROGGED MOST UNSTABLE CAPES EXPECTED IN EXCESS OF 1000 J/KG AND LITTLE CAPPING. THE TRAJECTORY OF THE SUBTROPICAL MOISTURE CONNECTION AND LIFT WITH THE SHORTWAVE ENERGY EJECTING FROM THE SOUTHERN PLAINS GIVES OUR KANSAS COUNTIES AND SOUTHEAST NEBRASKA COUNTIES THE BEST CHANCES FOR CONVECTION INITIALLY. A SECONDARY AREA FOR CONVECTION WILL BE FOCUSED ACROSS THE HIGH PLAINS IN CONVERGENCE ALONG THE DRY LINE...WITH THE DEEPENING TROUGH THIS AFTN IN ADVANCE OF ANOTHER MID LEVEL TROUGH EMERGING FROM THE NORTHERN ROCKIES. IN THIS SETUP...MUCH OF OUR CWA WILL BE IN BETWEEN THE MAIN CONVECTIVE ACTIVITY...BUT WILL STILL HAVE SOME CHC FOR PCPN. HAVE ATTEMPTED TO REORIENT PCPN CHANCES TODAY. OUR WESTERN COUNTIES ARE IN THE BUFFER OF THE DAY1 SLIGHT RISK...AND ALTHOUGH STRONGEST ACTIVITY MAY BE AROUND US...CANNOT RULE OUT A FEW STRONG STORMS AND WILL CONTINUE TO MENTION IN THE HWO. TEMPERATURES WILL WARM THIS MORNING PRIOR TO THE THICKENING CLOUD COVER BY AFTERNOON...WITH OVERALL 70S EXPECTED FOR HIGHS. THE LOWLEVEL JET REMAINS STRONG TONIGHT AND CONVECTION WILL LIFT OFF TO THE NORTHEAST. THURSDAY STILL REMAINS MORE INTERESTING FOR CONVECTION AND SEVERE WEATHER. AFTER A LULL IN THE MORNING...CHANCES FOR THUNDERSTORMS INCREASE DURING THE AFTERNOON. THE THETA-E AXIS EXTENDS ACROSS EASTERN KANSAS THROUGH PORTIONS OF SOUTH CENTRAL AND SOUTHEAST NEBRASKA. THE SURFACE LOW DEEPENS IN WESTERN KANSAS...THE MID LEVEL TROUGH PUSHES INTO THE DAKOTAS WITH THE COLD FRONTAL BOUNDARY ORIENTED FROM SOUTHWEST TO NORTHEAST NEBRASKA...AND THE DRY LINE SITUATED ACROSS WESTERN KANSAS. CONVECTION SHOULD INITIATE ALONG THE FRONTAL ZONE AND ALSO FARTHER EAST INTO SOUTHEAST NEB/NORTHEAST KANSAS ON THE NOSE OF THE LOWLEVEL JET. MAIN AREA OF CONCERN WILL BE THE FRONTAL ZONE AND THE WESTERN CONVECTION EVOLVING INTO AN MCS AND ROLLING EASTWARD THROUGH OUR CWA IN A PRIMARILY NOCTURNAL EVENT. INSTABILITY AND SHEAR PROFILES ARE GREATER THURSDAY/THURSDAY NIGHT LENDING TOWARD BETTER CHANCES FOR SEVERE WEATHER WITH LARGE HAIL/DAMAGING WINDS THE PRIMARY HAZARDS. THE COLD FRONT SWEEPS THROUGH THURSDAY NIGHT AND THE MCS SHOULD DEPART BY AROUND DAYBREAK FRIDAY. DRY...COOLER AIR ADVECTS SOUTHEAST BEHIND THE FRONT AND TEMPERATURES WILL COOL BACK TO SEASONAL NORMS...OR JUST A TAD BELOW. && .GID WATCHES/WARNINGS/ADVISORIES... NE...NONE. KS...NONE. &&
