AREA FORECAST DISCUSSION FOR SOUTHEAST SD/SOUTHWEST MN/NORTHWEST IA
NATIONAL WEATHER SERVICE SIOUX FALLS SD
851 PM CDT FRI MAY 7 2010

.DISCUSSION...
SCATTERED SHOWERS SLOWLY WINDING DOWN THIS EVENING AS THE SUN SETS
AS ARE THE WINDS. MUCH OF THE STRONGER WINDS WERE ACCOMPANIED BY THE
PASSING SHOWERS WITH A FEW GUSTS NEAR 50 MPH AT TIMES. MOST OF THESE
STRONGER GUSTS HAVE ALSO DISSIPATED AS THE SHOWERS HAVE WEAKENED AND
EXPECT THIS...ALONG WITH THE GRADIENT SLACKENING TO BRING A SLOW
DECREASE TO WINDS THROUGH THE NIGHT. SO...WIND ADVISORY ENDING AT 2Z
LOOKS GOOD. OTHERWISE...TEMPERATURES WILL CONTINUE TO FALL...BUT
WITH WINDS AT OR ABOVE 10 MPH THROUGH THE NIGHT...ESPECIALLY EAST OF
THE JAMES RIVER...DO NOT EXPECT FROST TO BE A PROBLEM. ALONG AND
WEST OF THE JAMES...WITH TEMPERATURES FALLING TO 30 OR A LITTLE
COLDER...THE FREEZE WARNING STILL LOOKS GOOD. EVEN THERE FROST MAY
NOT BE A MAJOR PROBLEM WITH SOME WIND...BUT STILL DARN COLD FOR THIS
LATE IN THE SEASON. /08

&&

.AVIATION...
GUSTY NORTHWEST WINDS WILL GRADUALLY DECREASE THIS EVENING AS
CANADIAN HIGH PRESSURE BUILDS INTO THE NORTHERN PLAINS. LOW VFR/
HIGH END MVFR CEILINGS ARE EXPECTED TO SLIDE SOUTH OUT OF EASTERN
NORTH DAKOTA INTO EASTERN SOUTH DAKOTA AND ESPECIALLY SOUTHWEST
MINNESOTA.  CONDITIONS MAY BECOME GUSTY ALONG AND EAST OF I-29 AS
MIXING MAY DRAW DOWN SOME MOMENTUM FROM ALOFT...BUT SHOULD OVERALL
DECREASE THROUGHOUT THE DAY AS HIGH PRESSURE BUILDS INTO THE AREA.
COULD SEE SOME FAIR WEATHER CUMULUS DEVELOP DURING THE DAYTIME
HOURS...MAINLY WITH BASES OF 4-6K FEET. /BT

&&

.PREV DISCUSSION...
STG NWLY FLOW MIXING OUT WELL INTO WND ADVY CRITERIA SWRN HLF CWA
WITH STEEP LAPSE RATES AND COLD ADVECTION...AND WILL HAVE TO BE
WATCHED ELSEWHERE IN CWA THIS EVE AS STG GRADIENT SPREADS ENEWD
BEHIND STRONG UPPER TROF. WRAPAROUND -SHRA WILL ALSO PULL EWD
THRU SWRN MN THIS EVE...PSBLY MIXING WITH BRIEF -SHSN IN HIGHER
ELEVATIONS. SC DECK WILL LINGER OVER MOST OF CWA...BUT START TO
BREAK UP THIS EVE WEST TO SOUTH IN CWA WHERE CLOUDS APPEAR PARTLY
DIURNALLY DRIVEN. SHOULD BE SOME CLRG WITH LIGHTER WINDS IN THE
WRN CWA LATE TNGT AND EARLY SAT AND WILL GO WITH FREEZE WARNING
OUT THERE WHERE TEMPS SHOULD FALL NEAR OR BELOW FREEZING. /RSR

SATURDAY LOOKS LIKE THE QUIETEST DAY IN THE NEAR FUTURE AS THE UPPER
LOW MOVES OUT AND THE NEXT SYSTEM BUILDS TO THE WEST. TEMPS WILL BE
HELD DOWN IN THE MORNING BY SOME LINGERING STRATUS AND A COLD
START...BUT SHOULD MIX FAIRLY WELL...ESPECIALLY IN THE EASTERN HALF
OF THE FA. KEPT PATCHY FROST IN THE GRIDS ON SATURDAY NIGHT WHERE
TEMPS WILL DROP TO NEAR 30...AND MAY NEED TO MONITOR SAT NIGHT FOR A
POSSIBLE HEADLINE. WAA PICKS UP AND CREATES SOME DECENT ISENTROPIC
LIFT ON SUNDAY...ALTHOUGH IT LOOKS LIKE THE MODELS...PARTICULARLY
THE 12Z NAM...ARE OVERDOING THE PRECIP A LITTLE.

TIMING AND PLACEMENT OF SYSTEM ON MONDAY IS FAIRLY CONSISTENT
BETWEEN MODELS...ALTHOUGH THE GEM IS SOMEWHAT OF AN OUTLIER AND
PUSHES THE LOW FURTHER NORTH. HAVE TRENDED TOWARDS THE OTHER
SOLUTIONS...PARTICULARLY THE GFS. ONLY REAL INSTABILITY THAT
DEVELOPS IS NORTH OF THE 850 LOW ON MONDAY AFTERNOON...SO HAVE
INCLUDED THUNDER ON THE DAYTIME AND EVENING PRECIP...OTHERWISE AM
STICKING WITH RAIN FOR THE REST OF THE PD. ALTHOUGH SHEAR LOOKS
PRETTY AMAZING ON MONDAY...SFC TEMPS ARE TOO COOL AND LAPSE RATE ARE
PRETTY POOR...SO AM DEFINITELY NOT WORRIED ABOUT A SVR THREAT IN OUR
CWA. WILL PROBABLY SEE SOME LINGERING PRECIP AND CLOUDS HOLDING DOWN
TEMPS ON TUESDAY...BUT SYSTEM SHOULD EJECT RELATIVELY QUICKLY ON
TUESDAY NIGHT.

AFTER THAT...NEXT SYSTEM STARTING TO COME INTO PLACE ON
THURSDAY...BUT IS NOT AS ORGANIZED AS THE MONDAY LOW. ATTM...LOOKS
LIKE MAJORITY OF PRECIP WILL BE THE SOUTH OF OUR FA...AND COULD JUST
SEE SOME LIGHT SHOWERS IN THE WRAP AROUND. WILL SEE SOME RECOVERY IN
THE TEMPS TOWARDS THE END OF THE PD...BUT HAVE STILL TRENDED
SOMEWHAT COOLER THAN PREVIOUSLY FCST DUE TO CONTINUAL NORTHERLY
WINDS AND CLOUD COVER FROM SYSTEMS PASSING TO THE SOUTH. FOR
NOW...KEPT PRECIP OUT OF THE FCST ON FRIDAY...BUT MAY NEED TO ADJUST
AS THE MODELS MAY BE A LITTLE TOO QUICK. /LAFLIN
