AREA FORECAST DISCUSSION FOR SOUTHEAST SD/SOUTHWEST MN/NORTHWEST IA
NATIONAL WEATHER SERVICE SIOUX FALLS SD
410 PM CST THU FEB 15 2007

.DISCUSSION...
FOR THIS EVENING...EXPECTING A SLIGHT DROP IN TEMPERATURES EARLY
THIS EVENING...THEN AS WIND BEGIN TO INCREASE AND WARMER AIR ADVECTS
INTO THE AREA...TEMPERATURES WILL BEGIN TO RISE THROUGH THE NIGHT.

MAIN FORECAST CHALLENGE AND CONCERN IS WITH LOW PRESSURE SYSTEM THAT
WILL TRACK ACROSS THE AREA FRIDAY. IN GENERAL...1 TO 3 INCHES OF
ACCUMULATION WILL BE LIKELY ACROSS THE AREA...BUT EXACT AMOUNTS WILL
DEPEND ON TRACK OF THE LOW. WINDS WILL PICK UP...ESPECIALLY TOMORROW
EVENING WITH THE PASSAGE OF A COLD FRONT. FORTUNATELY...THE
STRONGEST WINDS WILL BE ABOVE THE INVERSION LAYER...BUT SHOULD STILL
SEE 20 TO 30 MPH SUSTAIN OVER MUCH OF THE AREA BY TOMORROW EVENING
WITH GUSTS TO 40...CAUSING SOME LOWERED VISIBILITIES FROM BLOWING
SNOW. OF COURSE THIS WILL DEPENDANT ON TRACK AND STRENGTH OF LOW
PRESSURE. THINK MODELS MAY BE SLIGHTLY OVERDOING THE DEVELOPMENT OF
THE SURFACE LOW...GIVEN LATEST WATER VAPOR NOT INDICATING A WELL
DEFINED UPPER WAVE...BUT NONE THE LESS WILL PROBABLE NEED FOR SOME
SORT OF HEADLINE YET TO BE DETERMINE. THE OTHER THING TO WATCH IS
SOME INSTABILITY WITH THIS SYSTEM...COULD VERY WELL SEE SOME
CONVECTIVE ELEMENTS WITH THE PASSAGE OF THE MIDLEVEL COLD FRONT...AS
BOTH NAM AND GFS ARE SHOWING SOME INSTABILITY.

THE MONDAY THRU THU PERIOD WILL START ON A VERY MILD NOTE...WITH
SURFACE TEMPS OF COURSE STILL LIMITED BY SNOW COVER. MEANWHILE...ALL
AVBL MODELS BRING A NRN STREAM SHORTWAVE ACROSS THE NRN PLAINS LATER
MON AND MON NGT...BUT ALSO KEEP IT VERY WEAK AS MOST ENERGY GOES
INTO SRN STREAM WAVE WHICH REMAINS WELL SOUTH OF FCST AREA.
THEREFORE...WILL NOT ONLY KEEP THIS FOUR DAY PERIOD DRY...BUT IT
LOOKS LIKE TEMPS WILL COOL VERY SLIGHTLY IF ANY FOR TUE ESPLY GIVEN
SNOW COVER COMPLICATION. WITH PROJECTED FULL LATITUDE RIDGING OVER
PLAINS LATER IN THE WEEK...THE WHOLE PERIOD LOOKS DRY AND MILD. BY
LATE IN THE WEEK EVEN STRONGER WARMING MAY OCCUR AHEAD OF GFS
PROJECTED MAJOR TROF DVLPG OVER WRN UNITED STATES. HOWEVER THIS
STRONGER WARMING SHOULD OCCUR MOSTLY JUST AFTER FCST PERIOD END THU.
WILL FOR NOW KEEP HIGH TEMPS FOR THE PERIOD MOSTLY IN THE 30S WITH
SOME 40S SW/W...AS FOR NOW DONT EXPECT ANY SNOWMELT TO BE RAPID
ENOUGH FOR WARMER TEMPS THRU THU. GIVEN RECENT COLD WX...THERE SHUD
BE FEW COMPLAINTS FROM THOSE WANTING TO RUSH INTO THE 50S AND 60S.
POTENTIAL OF GFS SYSTEM FOR THE NEXT WEEKEND WILL BE INTERESTING TO
FOLLOW DURING THE INEVITABLE MAJOR CHANGES IN FCST MODEL SOLUTIONS.
FOR MON THRU THURSDAY...SIMPLY DRY AND MILD.
