.DISCUSSION...

ONE MORE MILD DAY BEFORE TEMPS BEGIN TO PLUMMET!

NORTHERN STREAM UPPER LEVEL SHORTWAVE CURRENTLY OVER SASKATCHEWAN
AND NRN MT WL CONTINUE TO DIG ACROSS THE NRN PLAINS TODAY. AT THE
SFC EARLY THIS MORNING...LOW PRESSURE WAS CENTERED OVER WRN ND
WITH SHARP CDFNT EXTENDING ACROSS THE WESTERN DAKOTAS. UPPER LEVEL
ENERGY WL HELP TO QUICKLY PUSH THE SFC CDFNT INTO THE FORECAST
AREA THRU THE DAY. WITH LACK OF MOISTURE...THE FRONT SHOULD COME
THRU DRY. WE EXPECT IT TO PASS THRU NRN COUNTIES BY LATE MORNING
AND THRU THE REMAINDER OF THE FORECAST AREA THRU THE AFTERNOON
HOURS. WINDS BEHIND THE FRONT WL LIKELY REACH THE BREEZY CATEGORY
FOR A WHILE WITH GUSTS AOA 30MPH WITH NEARLY 6MB 3-HR PRESSURE
RISES BEHIND THE FRONT.

STRONG CAA SHOULD DROP TEMPS SHARPLY BEHIND THE FRONT...ESPECIALLY
AFTER SUNSET. 850MB TEMPS WL START OUT AROUND +9C AT 12Z THIS
MORNING AND JUST 24 HOURS LATER WL BE ABOUT -6 TO -8C.

WL CONTINUE THE MENTION OF FLURRIES LATE WED NIGHT AND ALL DAY
THURSDAY AS UPPER LEVEL TROF APPROACHES FROM THE NORTH WITH A
SLIGHT INCREASE IN MOISTURE. DO NOT EXPECT ACCUMULATING SNOW...BUT
A FEW FLAKES ARE CERTAINLY POSSIBLE. TEMPS WL CONTINUE TO PLUMMET
WITH 850MB TEMPS BY FRI 00Z IN THE -13C RANGE. COLDEST LOWS OF THE
SEASON ARE FORECAST BY FRIDAY MORNING WITH SFC TEMPS CLOSE TO 10
TO 15F.
