AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DULUTH MN
546 PM CST SAT MAR 1 2014
.SHORT TERM...(TONIGHT AND SUNDAY)
THE TOPIC IN THE SHORT TERM IS THE COLD. EXTREMELY COLD TEMPS
TODAY WILL MEAN DANGEROUS COLD TONIGHT. TEMPS BARELY GOT ABOVE
ZERO IN NORTHERN WISCONSIN...AND DID NOT EVEN GET NEAR ZERO IN
MOST OF NORTHEASTERN MN. AND TEMPS WILL PLUNGE TONIGHT AS SOME OF
THE COLD AIR OF THE SEASON HAS ADVECTED INTO THE REGION. THE INL
RAOB THIS MORNING SHOWS 8H TEMP OF -30 WHICH WE ONLY SAW A HANDFUL
OF TIMES THIS WINTER...THE LATEST BEING THIS PAST THURSDAY. INL
HAD A LOW OF -36. DLH HAD A LOW OF -22. WILL SEE A NEAR REPEAT OF
THOSE COLD TEMPS AND WITH A LITTLE BIT OF WIND...WIND CHILLS WILL
BE VERY VERY DANGEROUSLY LOW...MINUS 45 TO MINUS 55. IT WILL AGAIN
BE BREEZY ON SATURDAY AS 8H WINDS OF 20 TO 25 KTS GET TRANSLATED
TO THE SFC.
OTHERWISE...THE HIGH PRESSURE OVER US WILL KEEP SKIES ON THE CLEAR
SIDE.
.LONG TERM...(MONDAY THROUGH SATURDAY)
MAIN CHANGE THIS PERIOD WILL BE THE COLLAPSE OF THE HUDSON BAY
TROUGH WHICH WILL ALLOW HEIGHT RISES OVER THE REGION. WESTERLIES
WILL BE SOMEWHAT SEPARATED INTO TWO STREAMS OF FLOW. CYCLOGENESIS
WILL BE TIED INTO SRN BRANCH WHERE A MORE SIGNIFICANT BAROCLINIC ZONE
WILL RESIDE. THE NRN BRANCH WILL FEATURE A PROGRESSIVE NATURE WITH
MIGRATORY SFC FEATURES CROSSING THE CWA. TEMPERATURES WILL MODERATE
THROUGH THE ENTIRE PERIOD WHICH SHOULD BE OF SOME RELIEF TO MOST
INHABITANTS OF THE TUNDRA.
IN TERMS OF SENSIBLE WEATHER A SFC HIGH WILL BUILD INTO THE REGION
SUN NIGHT/EARLY MONDAY AND BRING A CONTINUATION OF QUIET BUT COLD
CONDITIONS. HIGH PRESSURE WILL REFORM EAST OF THE REGION MON NIGHT
AS A MID LVL SHORTWAVE APPROACHES. A BRIEF PERIOD OF WARM ADVECTION
AND POSSIBLE MID LVL FRONTOGENESIS WILL SLIDE ACROSS THE SRN CWA MON
NIGHT/TUESDAY WITH LIGHT SNOW POSSIBLE. A CONFLUENT PATTERN ALOFT
WILL INCREASE OVER QUEBEC/ONTARIO WITH A LARGE SFC HIGH
EXPANDING SOUTHWEST INTO MIDWEST. THIS LEAVES THE REGION IN A BROAD
WARM ADVECTION REGIME WITH SOME INCREASE IN DEEP LAYER MOISTURE. LOW
CONFIDENCE IN PRECIP FCST AS MAIN FORCING WILL BE WARM ADVECTION AND
NOT SURE OF THE EXTENT OF LOW LAYER SATURATION. WILL KEEP POPS IN
FCST FROM WED TO EARLY FRIDAY PER LATEST ALLBLEND SOLUTION. A
DEEPENING MID LVL TROUGH WILL MOVE ACROSS MANITOBA INTO ONTARIO
THURSDAY. THIS SHOULD PROMOTE THE DEVELOPMENT OF A LLJ/MOISTURE
TRANSPORT AXIS INTO. THIS MIGHT BE THE MORE LIKELY TIME FOR PRECIP
AS AN ASSOCIATED COLD FRONT MOVES INTO THE AREA. FROPA AS OF NOW IS
EXPECTED THUR NIGHT/EARLY FRIDAY WITH CLEARING BEHIND THE BDRY
FRIDAY AFTERNOON. AIR MASS BEHIND THE FRONT WILL BE MORE CANADIAN VS
ARCTIC IN NATURE SO DO NOT ANTICIPATE MAGNITUDE OF CHILL AS BEING
WITNESSED CURRENTLY.

.AVIATION...(FOR THE 00Z TAFS THROUGH 00Z SUNDAY EVENING)
ISSUED AT 545 PM CST SAT MAR 1 2014
HIGH PRESSURE WILL KEEP THE VFR CONDITIONS OVER MUCH OF THE
NORTHLAND THROUGH THE PERIOD. AS WITH ARCTIC AIR MASSES...SOME
SPOTTY VSBY REDUCTIONS AND LOW CEILINGS MAY POP UP LATER TONIGHT
WITH VERY LITTLE MIXING.
SOME MID-HIGH CLOUDS WILL BRUSH SOUTHERN AREAS THROUGH THE EARLY
MORNING HOURS.
