.DISCUSSION...
COLD FRONT NOW MOVING THROUGH THE FORECAST AREA WILL USHER PLENTY OF
COLD AIR INTO THE REGION FOR THE LATTER PART OF THE WEEK RIGHT INTO
THE WEEKEND AS ARCTIC AIR CONTINUES TO SPILL SOUTH FROM CANADA. THIS
AIR MASS MEANS BUSINESS...AS TEMPS RIGHT NOW IN CENTRAL CANADA ARE
RUNNING IN THE -13 TO -26 DEGREE RANGE. MODIFICATION WILL OCCUR AS
IT HEADS SOUTH INTO THE STATES...BUT STILL SHOULD BE THE COLDEST AIR
OF THE SEASON WITH MANY AREAS IN THE UPPER TEENS BY SAT MORNING.
POST FRONTAL STRATUS CLOUDS WILL BE THE RULE FOR MUCH OF THE DAY
TODAY. LACK OF SUNSHINE AND BLUSTERY NORTH WINDS WILL LIKELY HOLD
TEMPS WITHIN A FEW DEGREES OF MORNING LOWS...AND SOME LOCATIONS MAY
ACTUALLY HAVE SLOWLY FALLING TEMPS IN THE AFTERNOON. WINDS WILL
LIKELY GUST INTO THE 15 TO 25 MPH RANGE...MAKING IT FEEL EVEN
COLDER.
WILL CONTINUE TO FAVOR THE COLDER MET MOS TEMPS TODAY THROUGH SAT.
MAV MOS HAS HAD A WARM BIAS...ESP ON MAX TEMPS WITH THE PAST COLD
SHOT...AND SEEMS TO BE HAVING THE SAME ISSUES WITH THE UPCOMING AIR
MASS. AFTER A CHILLY START IN THE 20 TO 25 DEGREE RANGE FRI
MORNING...WILL SEE HIGHS STRUGGLE TO GET ABOVE FREEZING MUCH OF THE
DAY IN SOME AREAS. THEN...AS THE BRUNT OF THE COLD SURFACE HIGH
MOVES OVERHEAD FRI NIGHT...WILL LIKELY EXPERIENCE LOW TEMPS IN THE
TEENS OVER A GOOD PORTION OF THE FORECAST AREA.
NEXT COLD FRONT/MID LVL SHORT WAVE WILL ENTER THE SCENE SUN
NIGHT...AND BRING THE NEXT CHC OF RAIN WITH IT.
