AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GLASGOW MT
916 AM MST FRI JAN 3 2014

.SHORT TERM...FOR NORTHEAST MONTANA...TODAY THROUGH SUNDAY...
GOING FORECAST SEEMS TO HAVE THINGS WELL AT HAND...BUT IT LOOKS
LIKE FRONT MAY BE MOVING IN A BIT SLOWER THAN PREVIOUS THINKING. LOTS
GOING ON TODAY. PRECIPITATION IN THE FORM OF RAIN THIS MORNING BUT
FREEZING ON MANY ROADWAYS AS GROUND TEMPERATURES ARE BELOW
FREEZING. THIS EXPECTED TO CONTINUE INTO THE EARLY AFTERNOON.

CANADIAN RADAR SHOWING A HEALTHY SWATH OF SNOW NEAR THE TRANS-CANADA
HIGHWAY AND MOVING SOUTH. THIS WILL BE ACCOMPANIED BY STRONG WINDS
LATER TODAY AS IT MOVES FROM NORTH TO SOUTH. VISIBILITIES WILL BE
GREATLY REDUCED AS THIS COMES THROUGH BUT PROBABLY DOWN TO A
MILE...SO NOT MEETING THE BLIZZARD CRITERIA OF A QUARTER MILE.
THEREFORE GOING WINTER WEATHER ADVISORY LOOKS GOOD AT THIS POINT.

A SURPRISE DOWNSLOPE NW WIND MAY OCCUR IN SW PHILLIPS AND PETRO CO
TODAY AS GUSTS TO 60-65 ARE POSSIBLE...THEREFORE ISSUED A HIGH
WIND WARNING FOR THIS AREA.

EARLIER UPDATE TOOK CARE OF THE HIGHER THAN EXPECTED TEMPS. JAMBA

PREVIOUS DISCUSSION...
AN ENERGETIC SHORT WAVE TROUGH...SEEN ON THE GOES WATER VAPOR
IMAGERY...SWEEPS INTO NORTHEAST MONTANA TODAY SENDING A COLD FRONT
THROUGH THE AREA. A CLOSED SURFACE LOW ALSO RUNS ACROSS THE REGION
PRODUCING STRONG WEST WIND THAT WILL VEER TO THE NORTHWEST BY
EVENING.

AN OVERNIGHT CHINOOK CAUSED SURFACE TEMPERATURES TO RISE IN
ADVANCE OF THE COLD FRONT. COMPLEX MODEL SOUNDINGS SUGGEST WARM
AIR WILL BE IN PLACE WHEN THE FRONT BEGINS TO MOVE INTO THE AREA.
SOUNDINGS SUPPORT RAIN ACROSS THE SOUTH IF ANY PRECIPITATION
OCCURS AHEAD OF THE FRONT WITH A MIX OF FREEZING RAIN OR SNOW IN
THE NORTH. COLD AIR MAY LINGER IN THE YELLOWSTONE VALLEY IN THE
MORNING LEADING TO SMALL POTENTIAL FOR SLEET. WITH THE COMPLEXITY
OF THE PRECIPITATION TYPE...USED THE TOP DOWN WX METHOD TO
DETERMINE MORNING AND AFTERNOON WX GRIDS. TEMPERATURES BEGIN
FALLING IN THE AFTERNOON AND BY 21Z EXPECT PRECIPITATION TO CHANGE
TO ALL SNOW. WITH WINDS TURNING NORTHERLY AND INCREASING WITH THE
COLD AIR ADVECTION BEHIND THE FRONT...AND WITH RECENT STILL LOOSE
SNOW...EXPECT EXTENSIVE BLOWING SNOW. WITH THE FAST MOVING FRONT
SNOW AMOUNTS WILL BE GENERALLY LIGHT...ONE TO TWO INCHES...BUT
WITH ADDITION OF THE BLOWING SNOW POTENTIAL A WINTER WEATHER
ADVISORY IS IN PLACE. SNOW AND WIND ARE EXPECTED TO EASE LATER
TONIGHT WITH WEAK HIGH PRESSURE PUSHING INTO EASTERN MONTANA.

A SECONDARY PUSH BY AN IMPRESSIVE INCOMING ARCTIC VORTEX WILL
RESULT IN FALLING TEMPERATURES ON SATURDAY WITH UP-SLOPE SNOW
DEVELOPING INTO CENTRAL MONTANA. THE POLAR VORTEX TYPE UPPER LOW
MOVES ACROSS SOUTHERN SASKATCHEWAN AND MANITOBA SATURDAY NIGHT.
THIS BRINGS AN EVEN COLDER ARCTIC COLD FRONT SOUTH WITH ENOUGH
MOISTURE THAT THERE COULD BE SOME LIGHT SNOW. BITTERLY COLD 850MB
TEMPERATURES AS COLD AS -35C MOVE ACROSS THE NORTHEAST CORNER OF
MONTANA SUNDAY MORNING. ARCTIC HIGH PRESSURE BUILDS INTO MONTANA
DURING THE DAY SUNDAY. SOME LOCATIONS WILL HAVE HIGHS NEAR -20.
THE MOVEMENT OF THE SURFACE HIGH WILL MAINTAIN MODERATE TO BRISK
WIND STRENGTH SATURDAY NIGHT AND SUNDAY. SO WITH THE VERY COLD
TEMPERATURES... WIND CHILLS WILL BECOME HAZARDOUS TO DANGEROUS.
SCT

.LONG TERM...SUNDAY NIGHT THROUGH FRIDAY...
POLAR VORTEX TYPE UPPER LOW MOVES TO THE EAST SUNDAY NIGHT. ARCTIC
HIGH PRESSURE WILL BE OVER EASTERN MONTANA WITH BITTER COLD
TEMPERATURES. WIND CHILLS WILL BE 40 BELOW TO 60 BELOW. SOME
AREAS WILL SEE -30S FOR LOWS SUNDAY NIGHT. IF SKIES ARE CLEAR ALL
NIGHT... A FEW LOCATIONS MAY SEE -40 OR COLDER.

NORTHERLY FLOW ALOFT BECOMES NORTHWEST ON MONDAY WHICH WILL ALLOW
TEMPERATURES TO MODERATE. HOWEVER...SHALLOW ARCTIC AIRMASS WILL BE
DIFFICULT TO DISLODGE FROM THE REGION SO IT WILL BE TUESDAY BEFORE
MOST AREAS SEE TEMPERATURES ABOVE ZERO FOR HIGHS. A WEAK WAVE ON
WEDNESDAY MAY HAVE ENOUGH MOISTURE FOR A SLIGHT CHANCE OF SNOW.

A SHORTWAVE RIDGE WILL WARM TEMPERATURES TO NEAR NORMAL WHICH WILL
CONTINUE INTO FRIDAY. FORRESTER
