Area forecast discussion, Dec 30, 11:47 AM CST, 43 minutes before
AREA FORECAST DISCUSSION...UPDATED NATIONAL WEATHER SERVICE DES MOINES IA 1147 AM CST TUE DEC 30 2008 .UPDATED THIS AFTERNOON/EVENING AND AVIATION DISCUSSIONS... THIS AFTERNOON EVENING... HIGH WIND EVENT DEVELOPING AS EXPECTED BUT IT NOW APPEARS LIKELY THAT ADVISORY CRITERIA WILL BE MET IN OUR SOUTHEASTERN/EASTERN COUNTIES AS WELL. HAVE THUS EXTENDED THE WIND ADVISORY TO INCLUDE THESE COUNTIES FROM 2 PM UNTIL 9 PM. ALSO TWEAKED TEMPERATURE TRENDS TODAY...BUT OTHERWISE NO SIGNIFICANT CHANGES MADE AT FORECAST UPDATE. PREVIOUS DISCUSSION... .SHORT TERM /TODAY/... THE MAIN ISSUE TODAY WILL BE THE WIND AS A VIGOROUS SURFACE LOW TRACKS SOUTHEAST THROUGH IOWA. THE GFS IS THE FAVORED MODEL FOR WIND SPEEDS AND TRENDS...GIVEN ITS SUPERIOR VERIFICATION AT 06Z REGARDING THE STRENGTH AND POSITION OF THE SFC LOW...THE POSITION OF THE SFC PRESSURE FALL BULLSEYE...AND THE TRACK OF THE H5 SHORTWAVE. WINDS WILL BECOME STRONG AROUND MIDDAY IN THE WESTERN COUNTIES...THEN PROGRESS EASTWARD THROUGH THE AFTERNOON. FORECAST SOUNDINGS INDICATE STEEP LOW LEVEL LAPSE RATES AND 40-50 KTS IN THE MIXED LAYER. THERE WILL ALSO BE STRONG SUBSIDENCE BEHIND THE WAVE TO CONTRIBUTE TO TRANSFERRING THE STRONG WINDS ALOFT DOWN TO THE SURFACE. WINDS WILL BE STRONGEST ALONG AND EAST OF INTERSTATE 35...WITH SUSTAINED SPEEDS AROUND 30 MPH AND GUSTS OF 45 MPH OR EVEN HIGHER. WILL ISSUE WIND ADVISORY FOR THIS AREA FROM 18Z-00Z. WIND SPEEDS APPEAR TO BE MARGINAL TO THE EAST...WITH LATER ONSET...SO WILL LET DAY SHIFT RE-EVALUATE AND EXTEND THE AREA OF THE ADVISORY IF NECESSARY. THERE WILL LIKELY BE SOME LIGHT SNOW ALONG THE TRAILING TROUGH AXIS IN NORTHERN IOWA...BUT AMOUNTS SHOULD BE LIMITED TO A HALF INCH OR LESS. TEMPERATURE TRENDS WILL BE TRICKY TO CAPTURE WELL TODAY...BUT THE SLIGHTLY FASTER GFS TIMING FAVORS HIGHS NEAR TO SHORTLY AFTER 18Z...THEN FALLING TEMPS DURING THE AFTERNOON. .LONG TERM /TONIGHT-MONDAY/... MAXIMUM 6HR PRESSURE RISES WILL BE EXITING TO THE EAST AND WITH SUN SETTING...THAT MAY BE ENOUGH TO TAKE THE EDGE OF THE PEAK GUSTS THIS EVENING. HOWEVER...THE DAY SHIFT CAN RE-EVALUATE THE NEED FOR A WIND ADVISORY FARTHER EAST THIS EVENING. OTHERWISE...HIGH PRESSURE BUILDS IN OVERNIGHT AND WINDS GO LIGHT BY MORNING. WEDNESDAY WILL BE COLD AN UNEVENTFUL. WARM ADVECTION KICKS IN WED NIGHT AHEAD OF NEXT CLIPPER SYSTEM THAT WILL TREK EAST ACROSS THE CANADIAN/CONUS BORDER THROUGH THURSDAY. WILL PROBABLY HAVE LOWS EARLY WED NIGHT...WITH TEMPS STEADY OR SLOWLY RISING AFTER MIDNIGHT. THERE MAY ENOUGH WARM ADVECTION AHEAD OF WARM FRONT CROSSING THE AREA WEST TO EAST ON NEW YEARS DAY TO PROVIDE SOME LIGHT SNOW...BUT BELIEVE THAT BEST CHANCES WILL REMAIN NORTHEAST OF OUR AREA. BY THE TIME ATMOSPHERE APPEARS TO SATURATE ENOUGH TO PRODUCE PRECIPITATION...THE LIFT IS WANING AND EXITING. HIGH PRESSURE AND SLIGHTLY COOLER ON FRIDAY. GFS/ECMWF HAVE SHOWN SOME CONSISTENCY REGARDING SNOW CHANCES SATURDAY AS TROWAL SIGNATURE...UPPER LEVEL WAVE...AND SURFACE INVERTED TROUGH MOVE THROUGH IOWA. THE GFS SHOWS MULTIPLE BANDS OF FRONTOGENESIS MOVING THROUGH DURING THE DAY WITH A BRIEF PERIOD OF MAX LIFT FOCUSED IN DENDRITIC GROWTH ZONE...AND BOTH MODELS SUGGEST SOME LIGHT ACCUMULATING SNOW FOR JUST ABOUT THE ENTIRE AREA. DUE TO REGIONAL CONSENSUS AND DISTANCE INTO THE FUTURE...HAVE KEPT POPS IN LOW END OF CHANCE RANGE...BUT DONT BE SURPRISED IF POPS FOR SATURDAY CREEP UP WITH TIME. NO OTHER SIGNIFICANT CHANGES MADE. && .AVIATION...30/18Z LOW PRESSURE SLIDING ACROSS NORTHERN IOWA ATTM WILL BRING THROUGH SIGNFICANT NORTHWESTERLY WIND SURGE...AFFECTING KFOD BY 18Z...KMCW AND KDSM BY 19Z...AND KALO AND KOTM BY 20Z. WINDS WILL BE HIGHEST AT THE SOUTHERN TERMINALS. MVFR CIGS WILL ALSO ACCOMPANY AND FOLLOW THE WIND SURGE ESPECIALLY AT THE NORTHERN SITES. LIGHT SNOW IS POSSIBLE AT KMCW...BUT LOW CONFIDENCE AND LIGHT NATURE OF PRECIP PRECLUDE MENTION IN 18Z TAF. WINDS WILL SUBSIDE THIS EVENING AND INTO TONIGHT...WITH KOTM BEING THE LATEST TO DROP AS THE TIGHTER GRADIENT MOVES AWAY TO THE SOUTHEAST. CLOUDS WILL ALSO CLEAR RAPIDLY DURING THE EVENING HOURS WITH CLEAR SKIES THEREAFTER. && .DMX WATCHES/WARNINGS/ADVISORIES...
