Area forecast discussion, Sep 12, 1:23 PM CDT, 7 hours 44 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE HASTINGS NE 123 PM CDT MON SEP 12 2005 .SHORT TERM...TONIGHT THROUGH THURSDAY MORNING. MAIN CONCERN REVOLVES AROUND SEVERE WEATHER POTENTIAL TONIGHT WITH SECONDARY QUESTION ABOUT CONVECTION POTENTIAL TOMORROW NIGHT ACROSS THE SOUTH. LATE MORNING ANALYSIS SHOWED POTENT UPR TROF MOVING INTO WESTERN WYOMING...WITH JET STREAK IN EXCESS OF 75KTS NOTED FROM BOTH 12Z SOUNDINGS AND WV IMAGERY NOSING INTO EASTERN COLORADO. WEAK FRONTAL BOUNDARY ALSO NOTED MIXING NORTH INTO NORTHERN NEBRASKA BY 17Z...WITH CLOUD FIELD RAPIDLY ERODING FROM EAST TO WEST OVER THE CWA. COLD FRONT REMAINED WELL WEST OF THE AREA...APPROACHING KTIF AT 18Z. AS LARGE SCALE ASCENT INCREASES THROUGH THE EVENING AHEAD OF APPROACHING UPR TROF AND SFC COLD FRONT...EXPECT TO SEE SCATTERED CONVECTION FIRE OVER THE NORTHERN CWA...AND HAVE KEPT HIGHEST POPS INTACT FROM PREVIOUS FCST ACROSS THIS AREA. WITH INCREASING DEEP SHEAR IN EXCESS OF 35KTS...RATHER STEEP MID-LEVEL LAPSE RATES AND INCREASING INSTABILITY...ANY STORMS WHICH FIRE SHOULD TURN SEVERE FAIRLY QUICKLY. HOWEVER...THE QUESTION REMAINS JUST WHERE CONVECTION WILL INITIALLY FIRE. GIVEN NORTHERN EXTENT OF SFC BOUNDARY THIS AFTN AND STRONG CAPPING TEMPS OF 12C+ AT H7 OVER MUCH OF THE CWA...IT IS POSSIBLE THAT CONVECTION MAY FIRE OUTSIDE THE CWA...AND THEN GRADUALLY WORK ITS WAY SOUTH INTO THE NIGHTTIME HOURS. COULD ALSO SEE ISOLD CONVECTION FIRE ALONG SURGING DRYLINE INTO WESTERN KANSAS AS EVIDENCED BY POCKET OF INCREASED RH AT H7 IN 12Z MODEL PLOTS... WORKING EAST INTO KANSAS COUNTIES THIS EVENING. GIVEN PLENTY OF UNCERTAINTIES...HAVE KEPT SMALL POPS ACROSS MUCH OF THE AREA TONIGHT...ALTHOUGH THESE CERTAINLY MAY NEED TO BE ADJUSTED TO BETTER FIT FUTURE DEVELOPMENTS. COLD FRONT WILL MAKE ITS WAY THROUGH THE CWA BY TOMORROW MORNING AS UPR TROF MOVES ACROSS THE AREA...WITH SFC RIDGE AXIS BUILDING THROUGH THE CENTRAL PLAINS. WITH LINGERING MOISTURE AROUND...COULD SEE SOME LOWER CLOUDS DEVELOP TOWARD MORNING IN FRONTAL INVERSION... SIMILAR TO WHAT OCCURRED OVER NORTHERN NEBRASKA THIS MORNING. OTHERWISE...COOLER AND MUCH DRIER AIR STILL LOOKS ON TARGET TO ARRIVE BY TOMORROW AFTN. GIVEN MUCH LOWERED CONVECTIVE TEMPS IN THE LOW/MID 70S...EXPECT TO SEE STRATOCU FIELD FILL IN...WHICH SHOULD HOLD AFTN TEMPS IN THE 70S FOR MOST AREAS. SFC HIGH CONTINUES TO BUILD ACROSS THE AREA TOMORROW NIGHT...WITH DEEP EASTERLY FLOW DEVELOPING INTO THE HIGH PLAINS. AS SUCH...COULD SEE CONVECTION FIRE OVER WESTERN KANSAS PUSHING EAST INTO NORTH CENTRAL KANSAS. CHANCES LOOK PRETTY SMALL AT THIS POINT...HOWEVER DECIDED TO ADD SMALL POPS FOR THIS AREA TO ACCOUNT FOR POTENTIAL. OTHERWISE...WITH RIDGE AXIS OVERHEAD... NORTHERN AREAS SHOULD SEE TEMPS FALL WELL INTO THE 40S...WITH 50S ELSEWHERE. RETURN FLOW BEGINS TO SET UP LATE WEDNESDAY AS HIGH PRESSURE MOVES WELL EAST OF THE AREA...HOWEVER WITH STALLED FRONTAL BOUNDARY OVER THE SOUTHERN PLAINS...MOISTURE RETURN LOOKS MEAGER AT BEST AND HAVE DECIDED TO HOLD OFF ON ANY PRECIP MENTION AT THIS TIME. .LONG TERM...12Z THURSDAY THROUGH MONDAY...MAIN FORECAST PROBLEM SURROUNDS RAIN CHANCES FRIDAY NIGHT INTO SATURDAY. THE GFS CONTINUES TO ADVERTISE A WAVE MOVING ACROSS THE CENTRAL PLAINS FRIDAY NIGHT INTO SATURDAY. THE 00Z ECMWF ALSO BRINGS THIS FEATURE ACROSS...BUT IT IS MUCH WEAKER IN ITS DEPICTION. HAVE DECIDED TO ADD A SMALL CHANCE OF THUNDERSTORMS FRIDAY NIGHT INTO SATURDAY WHEN THE MODELS AGREE THE WAVE WILL BE MOVING THRU. THE REMAINDER OF THE FORECAST SHOULD BE MAINLY DRY AS AN UPPER LEVEL RIDGE BUILDS INTO THE REGION DURING THE WEEKEND. SHORTWAVES WILL TOP THE RIDGE AT TIMES...AND THESE WILL HAVE TO BE WATCHED...BUT THE MAIN ENERGY SHOULD PASS NORTH OF THE FORECAST AREA. TEMPERATURES SHOULD ALSO GRADUALLY WARM BACK INTO THE 80S AS THE RIDGE BUILDS INTO THE REGION. && .GID WATCHES/WARNINGS/ADVISORIES... NE...NONE KS...NONE && LAWRENCE/KING
