.DISCUSSION...

PER LATEST OBS AND CURRENT RADAR IMAGES...TEMPERATURES CONTINUE TO
SLOWLY FALL THIS AFTERNOON WITH WIDELY SCATTERED SNOW SHOWERS STILL
OCCURRING OVER THE AREA. THE MOST PERSISTENT ACTIVITY HAS PUSHED
INTO NEBRASKA...THOUGH WE COULD STILL SEE SOME ISOLATED FLURRIES AND
SNOW SHOWERS THROUGH THE EARLY EVENING. WILL CONTINUE TO SEE WINDY
CONDITIONS THROUGH THE EVENING HOURS...THEN DIMINSHING WINDS AFTER
MIDNIGHT AS SURFACE HIGH PRESSURE CURRENTLY OVER SASKATCHEWAN PUSHES
INTO THE NORTHERN PLAINS DURING THE NIGHT. WITH THE COMBINATION OF
BREEZY CONDITIONS AND VERY COLD TEMPERTURES...HAVE ISSUED A WIND
CHILL ADVISORY FOR AREAS NORTH OF INTERSTATE 90 AFTER 03Z...AND
AREAS TO THE SOUTH OF THIS AFTER 08Z. HAVE COLDEST TEMPERATURES IN
OUR WESTERN ZONES...CLOSER TO THE HIGH PRESSURE CENTER. IF THE
PRESSURE CENTER WOULD TRACK A LITTLE FARTHER TO THE EAST...AND WINDS
GO LIGHT...I MIGHT NOT BE QUITE COLD ENOUGH OVER THESE AREAS...AND
LATER SHIFTS WILL NEED TO MAKE AN ADJUSTMENT.

ON TUESDAY WE SEE THE CONTINUATION OF OUR CURRENT PATTERN...WITH A
SHORTWAVE MOVING THROUGH THE AREA ABOUT EVERY OTHER DAY...FOLLOWED
BY COLDER AIR AND WINDY CONDITIONS COMING IN BEHIND EACH SYSTEM.
SPECIFICALLY...AFTER ANOTHER VERY COLD DAY ON TUESDAY...WAA WILL
ENSUE ON TUESDAY NIGHT AND WEDNESDAY AHEAD OF THE NEXT WAVE. THIS
WAVE WILL BRING A SMALL CHANCE OF LIGHT SNOW AGAIN ON
WEDNESDAY...FOLLOWED BY COLDER AIR ON WEDNESDAY NIGHT. AFTER A BRIEF
WARM UP ON THURSDAY...ANOTHER SHORTWAVE SWINGS THROUGH THE REGION ON
THURSDAY AFTERNOON AND THURSDAY NIGHT...AGAIN BRINGING A SLIGHT
CHANCE OF SNOW...AND OPENING THE DOOR TO ARCTIC AIR POISED OVER

WINTER WEATHER...
SNOW SHOWERS WILL MOVE SOUTHEAST ACROSS THE AREA
TODAY...DIMINISHING FROM NORTHWEST TO SOUTHEAST THROUGH THE
AFTERNOON. SNOWFALL AMOUNTS WILL GENERALLY BE LIGHT...HOWEVER
LOCALIZED HEAVIER SNOW SHOWERS COULD PRODUCE AMOUNTS UP TO AN
INCH BY THIS EVENING. GUSTY NORTHWEST WINDS WILL ACCOMPANY THE

THESE STRONG WINDS WILL CAUSE BLOWING AND DRIFTING OF THE FRESHLY
FALLEN SNOW...RESULTING IN REDUCED VISIBILITIES AND SLIPPERY
STRETCHES ON ROADWAYS AS THE SNOW BLOWS ACROSS THE ROAD.
VISIBILITY IN OPEN AREAS COULD OCCASIONALLY FALL BELOW A
MILE...AND MOTORISTS SHOULD BE PREPARED FOR CHANGING DRIVING
CONDITIONS TODAY.

COLDER AIR WILL PUSH BACK INTO THE AREA TONIGHT. TEMPERATURES ARE
EXPECTED TO FALL BELOW ZERO NORTH OF A MITCHELL TO CANTON SOUTH

TO 45 MPH THROUGH THE AFTERNOON. STRONGEST WINDS ARE LIKELY
THROUGH THE JAMES AND MISSOURI RIVER VALLEYS.

.DAYS TWO THROUGH SEVEN...TUESDAY THROUGH SUNDAY

A REINFORCING PUSH OF COLDER AIR WILL MOVE INTO THE REGION LATE
IN THE WEEK. SUB-ZERO LOW TEMPERATURES ARE LIKELY BOTH THURSDAY
NIGHT THROUGH THE WEEKEND...WITH DAYTIME TEMPERATURES STRUGGLING
TO CLIMB INTO THE SINGLE DIGITS ABOVE ZERO BY SUNDAY. AT THIS

POTENTIAL FOR WIND CHILL READINGS OF 20 BELOW TO 40 BELOW ZERO
THROUGHOUT THE AREA.
