AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE SPRINGFIELD MO 534 PM CST MON JAN 16 2012 ...AVIATION UPDATE... .DISCUSSION... MAIN FOCUS IN THIS FORECAST PACKAGE WILL CONTINUE TO FOCUS ON THE VERY WARM AND BREEZY CONDITIONS FOR THE REMAINDER OF THIS AFTERNOON. THEN ATTENTION TURNS TO SHOWER AND THUNDERSTORM CHANCES THIS EVENING INTO TONIGHT...AHEAD OF A STRONG COLD FRONT THAT WILL USHER IN MUCH COLDER CONDITIONS ON TUESDAY. CURRENTLY...TEMPERATURES ARE GENERALLY IN THE MIDDLE 60S TO THE LOWER 70S ACROSS THE AREA. THESE CONDITIONS ARE VERY WARM FOR THIS TIME OF YEAR...AND NEARING OR EXCEEDING RECORD HIGHS FOR MANY LOCATIONS. LOW LEVEL MOISTURE IS ALSO STREAMING NORTH INTO THE REGION...AS DEWPOINTS HAVE INCREASED INTO THE 50S. THE LOW LEVEL JET WILL INCREASE THIS EVENING ACROSS ARKANSAS AND NOSE INTO SOUTHERN MISSOURI. SHOWERS WILL LIKELY DEVELOP IN THIS AREA OF LIFT AHEAD OF THE JET ACROSS ARKANSAS AND MAY CLIP FAR SOUTH CENTRAL MISSOURI LATER THIS EVENING. AS AN UPPER LEVEL TROUGH PUSHES ACROSS THE PLAINS THIS EVENING... AN ASSOCIATED COLD FRONT WILL SWEEP SOUTHEAST INTO AND THROUGH THE AREA LATE THIS EVENING INTO THE OVERNIGHT HOURS. THE WARM AND MOIST AIRMASS THAT IS SPREADING INTO THE AREA WILL RESULT IN INSTABILITY INCREASING THIS EVENING...WITH ML-CAPE VALUES OF 400 TO 700 J/KG POSSIBLE. A VERY STRONG CAP IS ACROSS THE AREA AS AN ELEVATED MIX LAYER IS IN PLACE. THE CAP IS EXPECTED TO REMAIN STRONG ENOUGH TO PREVENT ANY STORMS TO DEVELOP AHEAD OF THE FRONT THROUGH THE BETTER PART OF THIS EVENING. THE FRONT SHOULD HAVE ENOUGH FORCING TO GENERATE SOME SHOWERS AND THUNDERSTORMS ALONG IT LATER THIS EVENING INTO THE OVERNIGHT HOURS. CELL MOTION LOOKS TO BE PARALLEL TO THE FRONT...SO EXPECT STORMS TO BE MORE POST FRONTAL IN NATURE. WIND SHEAR IS STRONG WITH 0-6KM VALUES GREATER THAN 60KT...WHICH WOULD SUPPORT ORGANIZED STORMS. HOWEVER...STORMS MAY HAVE A HARD TIME MAINTAINING THEMSELVES DUE TO THE STRONG SHEAR AND MARGINAL INSTABILITY... THE POTENTIAL EXISTS FOR STORMS TO SHEAR OUT. THEREFORE...DO NOT EXPECT WIDESPREAD SEVERE WEATHER BUT A FEW STRONG TO MARGINALLY SEVERE STORMS COULD BE POSSIBLE WITH LARGE HAIL TO THE SIZE OF QUARTERS BEING THE MAIN SEVERE RISK. A MUCH COLDER AND DRIER AIRMASS WILL SLAM INTO THE AREA BEHIND THE FRONT TONIGHT INTO TUESDAY. THE DRIER AIRMASS SHOULD QUICKLY SPREAD INTO THE AREA...SO EXPECT PRECIPITATION TO COME TO AN END BEFORE THE COLD AIR MOVES IN. THERE COULD BE A BRIEF PERIOD OF DRIZZLE TOMORROW MORNING...BUT FEEL THE DRY AIR WILL QUICKLY MOVE IN AND SHUT OFF THE PRECIPITATION. HIGHS ON TUESDAY AFTERNOON WILL BE OVER 30 DEGREES COLDER THAN THOSE THAT ARE CURRENTLY BEING OBSERVED THIS AFTERNOON...AS THEY ONLY TOP OUT IN THE 30S. OVERNIGHT LOWS WILL DROP INTO THE TEENS. THESE COLDER TEMPERATURES WILL BE USHERED IN ON BRISK NORTHWEST WINDS...WHICH WILL RESULT IN WIND CHILL VALUES FALLING WELL INTO THE TEENS TO THE UPPER SINGLE DIGITS TUESDAY NIGHT INTO WEDNESDAY NIGHT. THE COLDER TEMPERATURES WILL BE SHORT LIVED AS SOUTHERLY FLOW AND A WARMING TREND WILL MOVE RIGHT BACK INTO THE REGION ON WEDNESDAY. HIGHS SHOULD WARM INTO THE 40S AND 50S THROUGH THE END OF THE WEEK. A WEAK UPPER LEVEL DISTURBANCE WILL MOVE ACROSS THE AREA ON FRIDAY AND MAY BRING A FEW LIGHT SHOWERS TO THE AREA. THEN UPPER LEVEL RIDGING WILL BUILD RIGHT BACK OVER THE AREA THIS WEEKEND WITH HIGHS IN THE 60S ONCE AGAIN EXPECTED BY SUNDAY. ANOTHER UPPER LEVEL TROUGH WILL THEN SWEEP ACROSS THE AREA LATE SUNDAY INTO THE START OF NEXT WEEKEND...BRINGING ADDITIONAL CHANCES FOR RAINFALL TO THE REGION. WISE && .AVIATION... PILOTS FLYING IN AND OUT OF THE SOUTHWEST MISSOURI AIRPORTS WILL NEED TO MONITOR FOR DEVELOPING THUNDERSTORMS LATE THIS EVENING AND THROUGH THE OVERNIGHT HOURS. A STORM SYSTEM AND ASSOCIATED COLD FRONT CONTINUES TO APPROACH THE REGION FROM THE WEST. THIS FRONT WILL ALSO CAUSE SURFACE WINDS TO SHIFT TO THE NORTHWEST UPON PASSING THROUGH SOUTHERN MISSOURI LATE TONIGHT. ANY STORMS THAT MOVE DIRECTLY OVER AN AIRPORT...WILL CAUSE LOWER VISIBILITIES AND CEILINGS. THIS WILL BE HANDLED IN AMENDMENTS...HOWEVER...WE DO HAVE THUNDER MENTIONED IN ALL THREE TERMINAL AERODROME FORECASTS. CRAMER && .SGF WATCHES/WARNINGS/ADVISORIES... MO...NONE. KS...NONE. &&
