AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TWIN CITIES/CHANHASSEN MN
1244 PM CDT TUE OCT 23 2012

.AVIATION... /18Z TAF ISSUANCE/

A WARM FRONT OVER SOUTHERN MN WILL CONTINUE TO LIFT THIS
AFTERNOON. CONFIDENCE HIGHEST FOR MVFR CEILING INTO THIS
EVENING AT KMSP WITH 4 TO 8 HUNDRED FOOT CEILINGS COMMON ELSEWHERE
WITH VISIBILITIES IMPROVING TO 2 TO 4 MILES. KAXN WILL BE AT THE
LOW END OF THESE VALUES. THERE IS A SMALL CHANCE FOR A FEW
THUNDERSTORMS TONIGHT...ESPECIALLY OVER WEST CENTRAL WI. INDICATE
VCSH FOR KRNH AND KEAU. WITH VERY MOIST LOW LEVEL AIR OVERHEAD
TONIGHT...IT APPEARS ALL TAF SITES WILL SINK BACK TO LIFR OR EVEN
VLIFR IN STRATUS AND FOG. CONDITIONS MAY NOT IMPROVE VERY FAST ON
WEDNESDAY WITH A NEARLY STATIONARY FRONT NE-SW ACROSS THE AREA.

KMSP...EXPECT CEILINGS THIS AFTERNOON IN THE 015-020 FOOT RANGE
ALONG WITH 5-6SM VISIBILITY. SMALL THREAT FOR SHRA/TSRA ACTIVITY
AFTER 23Z TO THE EAST OF THE AIRFIELD. CONFIDENCE NOT HIGH ENOUGH
ATTM TO INCLUDE VCSH. A DETERIORATING TREND ONCE AGAIN TONIGHT
WITH LIFR/VLIFR LIKELY IN THE 08Z-14Z TIME FRAME. SOME IMPROVEMENT
LATE IN MORNING ON WEDNESDAY...WITH LOW MVFR IN THE AFTERNOON.

/OUTLOOK FOR KMSP/
WED...IFR CIGS/VSBYS IMPROVING TO MVFR. SHRA/TSRA IN THE AFTN/NIGHT.
      WINDS N 5-10 KTS.
THU...IFR/LOW MVFR CIGS/VSBYS. SHOWERS. WINDS NW 10-15 KTS.
FRI...VFR. WINDS NW 10-15 KTS.

.DISCUSSION... /ISSUED 315 AM CDT TUE OCT 23 2012/

SHRTWV ACROSS EASTERN SD/NE NEBRASKA ALONG WITH AMPLE MOISTURE
SURGING NORTHWARD FROM EARLIER CONVECTION ACROSS SOUTHERN IA...HAS
LED TO MORE NUMEROUS SHRA/TSRA DEVELOPMENT ACROSS S MN. IT LOOKS
AS THOUGH THESE STORMS WERE ABLE TO TAP SOME ELEVATED INSTABILITY
ACROSS S MN DURING THE OVERNIGHT HRS. HOWEVER...THIS SHOULD BE
SHORT LIVED AS DEEPER MOISTURE WILL LIFT NORTHWARD ALLOWING FOR
MAINLY -DZ/FG TO PERSIST ACROSS S MN BEFORE DRIER AIR BEGINS TO
EVADE FROM THE CENTRAL PLAINS. THE DRIER AIR IS ALSO ANOTHER
PROBLEM AS THE FG/STRATUS HAS DEVELOPED AS FAR SOUTH AS KANSAS
WHICH MAY CONTINUE THE LOWER CLDS/FG IN S MN THEN PREVIOUS
FORECAST THAT HAD SOME SUNSHINE THIS AFTN. BIGGEST FACTOR FOR
CONTINUING FG/LOW CLDS THRU MIDDAY IS WHETHER THE DEPTH OF THE
STRATUS ACROSS NE/KS IS SHALLOW ENOUGH TO MIX OUT. WITH A MORE
PESSIMISTIC FORECAST ON CLD CVR...HAD LOWERED AFTN TEMPS A FEW
DEGREES. MAINLY FOLLOWING A SURGE OF HIGHER DEW PTS WHICH WILL
LEAD TO TEMPS IN THE 60S...WITH A FEW 70S ALONG THE IA BORDER.

AFT THE MORNING CONVECTION...MOST OF THE SHORT TERM FORECAST WILL
DEAL WITH THE STRONG SHRTWV/LONG WAVE TROUGH ACROSS THE WESTERN
U.S. AND HOW IT WILL TRANSLATE ACROSS THE PLAINS...AND INTO THE
UPPER MIDWEST BY MIDWEEK. MODELS ARE DEPICTING SEVERAL WEAK
SHRTWV/S RIDING NE ALONG A NEARLY STATIONARY FRONTAL BOUNDARY
LATER TONIGHT ACROSS EASTERN MN. ALONG AND AHEAD OF THIS
FRONT...VERY MILD AIR WILL LEAD TO ADDITIONAL CONVECTION...BUT
UNCERTAINTIES EXIST ON HOW WIDESPREAD THE ACTIVITY BECOMES IN THE
NEXT 24 HRS. WILL LEAN TOWARD ONLY CHC POPS THROUGH LATE
TONIGHT...BEFORE THE MAIN SHRTWV AND UPPER LEVEL SUPPORT SHOULD
INDUCE A LONG AREA OF PRECIPITATION ACROSS THE UPPER MIDWEST.
PRECIPITABLE WATER VALUES ARE OVER ONE INCH ALONG AND SOUTH OF
THIS FRONT...SO RAINFALL AMTS COULD BE LOCALLY HEAVY IN SC/EC MN
AS WELL AS WC WI ON WED/EARLY THU. ONCE THE MUCH COOLER AIR BEGINS
TO FILTER ACROSS THE UPPER MIDWEST...EXPECT RAINFALL AMTS TO
LESSEN...WITH THE CHC OF -SN IN WC MN EARLY THU MORNING BEFORE THE
PRECIPITATION ABRUPTLY ENDS BY MIDDAY. COOL -RA WILL OCCUR IN THE
EASTERN FA WHICH DEEPER MOISTURE WILL HOLD ON UNTIL THE LATE AFTN.

THE EXTENDED PERIOD REMAINS THE SAME WITH THE LARGE LONG WAVE
TROUGH DEVELOPING ACROSS THE U.S...MAINLY EAST OF THE ROCKIES.
THERE REMAINS SOME SUBTLE WAVES LATE IN THE WEEKEND...EARLY NEXT
WEEK ALONG THE TRANSITION ZONE OF MORE PACIFIC AIR MOVING ACROSS
THE ROCKIES. THIS MAY GENERATE A FEW RAIN OR SNOW SHOWERS
SUNDAY...AND POSSIBLE MONDAY. HOWEVER...BY MONDAY THE ATMOSPHERE
SHOULD BE WARM ENOUGH TO BE ALL IN THE FORM OF RAIN.
