AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE DULUTH MN
646 AM CDT TUE MAY 13 2014

.SHORT TERM...(TODAY THROUGH WEDNESDAY)
ISSUED AT 338 AM CDT TUE MAY 13 2014

THE SURFACE LOW WAS LOCATED OVER THE ARROWHEAD OF MINNESOTA AS OF
08Z WITH THE UPPER TROUGH EXTENDING THROUGH MANITOBA INTO THE
DAKOTAS/WESTERN MINNESOTA. THE RAIN HAS DIMINISHED QUITE A BIT
ACROSS THE AREA WITH MAINLY SOME VERY LIGHT RAIN/DRIZZLE IN SPOTS.
WE EXPECT MINIMAL COVERAGE/INTENSITY OF THE PRECIP THIS MORNING AS
THE SURFACE LOW CONTINUES TO MOVE NORTHEAST. COLDER AIR CONTINUES
TO MOVE ACROSS THE REGION BEHIND THE DEPARTING LOW. SNOW WAS
REPORTED AT SEVERAL OBSERVATIONS...INCLUDING
KVWU/KBDE/KFGN/KRRT/CYQK. RADAR SHOWS SOME OF THAT MAY AFFECT KINL
THIS MORNING...AND WE HAVE A CHANCE FOR SOME SNOW OVER OUR
NORTHERN ZONES THROUGH 16Z.

SHOWERS SHOULD DEVELOP ACROSS MUCH OF OUR MN ZONES INTO FAR
NORTHWEST WI THIS AFTERNOON. COLD TEMPS ALOFT AND SOME SHORTWAVE
ENERGY WILL HELP PROVIDE A FAVORABLE SET UP FOR AT LEAST SOME
SCATTERED SHOWERS IN SPOTS. WE EXPECT THE BOUNDARY LAYER TO WARM
ENOUGH FOR MAINLY RAIN...BUT WOULD NOT BE SURPRISED TO HEAR OF SOME
LOCALIZED SNOW SHOWERS/SLEET INTO THE AFTERNOON IF CORES ARE
STRONG ENOUGH. HIGHS SHOULD REACH THE UPPER FORTIES TO LOWER
FIFTIES.

WE KEPT A MENTION OF SHOWER INTO THE EVENING OVER PORTIONS OF
NORTHEAST MN...THEN WENT DRY LATE EVENING ON. LOWS WILL DROP INTO
THE THIRTIES.

THE UPPER TROUGH WILL MOVE A BIT FURTHER EAST INTO MINNESOTA ON
WEDNESDAY. WE HAVE CHANCE FOR MORE SHOWERS ACROSS NORTHEAST MN AND
FAR NORTHWEST WI FROM LATE MORNING INTO THE AFTERNOON. TEMPS ALOFT
REMAIN RATHER COLD...SO WE DO MENTION SOME SNOW SHOWERS OVER FAR
NORTHERN MINNESOTA AGAIN. WE WENT ALL RAIN SHOWERS LATE WEDNESDAY
MORNING INTO THE AFTERNOON...BUT AGAIN SOME ISOLATED MIXED
RAIN/SNOW SHOWERS MAY OCCUR IF PRECIP RATES ARE HIGH ENOUGH. HIGHS
WILL RANGE FROM THE UPPER FORTIES TO MID FIFTIES.

.LONG TERM...(WEDNESDAY NIGHT THROUGH MONDAY)
ISSUED AT 338 AM CDT TUE MAY 13 2014

THE EXTENDED PERIOD WILL BE DOMINATED BY A STAGNANT UPPER TROF OVER
THE CENTRAL US THAT WILL EVENTUALLY CLOSE OFF...AGAIN...LATE IN THE
WEEK.  THIS WILL KEEP THE NORTHLAND IN A SOMEWHAT CLOUDY...COOL AND
WET PATTERN, ALTHOUGH THE WETTEST PERIOD IS PROBABLY BEHIND US.

A COLD FRONT WILL MOVE ACROSS THE NORTHLAND WEDNESDAY...BUT UPPER
TROF COULD KEEP SHOWERS LINGERING INTO THE EVENING...MAINLY IN
EASTERN AREAS OF CWA. BUT THAT WILL BE SHORT-LIVED AS EXPECT SOME
SHOWERS TO POP UP THURSDAY AS A COLD POOL ALOFT WILL CAUSE STEEP
ENOUGH LAPSE RATE TO GENERATE SOME SHOWERS. WITH TORRIDNESS SLOW TO
MOVE OUT...EXPECT THE SHOWERS TO CONTINUE IN THE EASTERN SECTIONS
INTO FRIDAY.  WITH THE UPPER LOW CLOSING OFF OVER THE
AREA...NORTHERN WISCONSIN OR WESTERN LAKE SUPERIOR...KEPT SHOWERS
INT HE FORECAST IN THE EAST INTO SATURDAY...BUT CHANCES ARE SMALL.
IT WILL BE QUITE COOL WITH 8H TEMPS FALLING TO -4 TO -8 AND STAYING
PUT THROUGH FRIDAY. SO SOME BELOW FREEZING TEMPS EXPECTED.  THE
CLOSED LOW WILL SLOWLY MOVE EAST ROUGH THE PERIOD AND BY LATE IN THE
WEENED BE EITHER OVER CENTRAL OT OR THE UP OF MI.  BUT THIS ALLOW
SOME SUN AND DRYING OVER THE WEEKEND. THEN ON MONDAY ANOTHER LOW
WILL DIG INTO THE WEST COAST AND PROVIDE ANOTHER SFC LOW TO MOVE
TOWARD THE REGION FOR THE REST OF THE WEEK.
