AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GLASGOW MT
407 AM MST SUN JAN 15 2012

.SHORT TERM...FOR NORTHEAST MONTANA...TODAY THROUGH TUESDAY...
A RIDGE OVER EASTERN MONTANA IS SLOWLY BEING PUSHED INTO THE
NORTHERN PLAINS BY AN UPPER TROUGH MOVING SOUTHEAST OUT OF BRITISH
COLUMBIA INTO THE NORTHWEST US. THE COLDEST AIR OF THIS WINTER IS
MAKING A TRIP DOWN THE CANADIAN FRONT RANGE HEADED FOR CENTRAL AND
EASTERN MONTANA. THERE IS ALSO AN UPPER RIDGE BUILDING TOWARDS
THE BEARING STRAIGHT AND WILL EVENTUALLY FORM AN OMEGA BLOCK. THIS
WILL KEEP EASTERN MONTANA IN THE ARCTIC AIR FOR THE UP COMING
WEEK.

SUNDAY THROUGH MONDAY...ARRIVAL OF THE ARCTIC FRONT WILL BE SHORTLY
AFTER SUNRISE THIS MORNING. EXPECT THE OVERNIGHT LOW TEMPERATURES
TO BASICALLY BE THE DAYTIME HIGHS ACROSS EASTERN MONTANA. 850 MB
TEMPERATURES WILL DROP 4* C THIS MORNING TO -22* C BY THIS
EVENING. THE STRONG WINDS ALFOT IN THE THE FORM OF A 50 TO 70 KNOT
JET CORE WILL BE BROUGHT CLOSE TO THE SURFACE THIS AFTERNOON BY
THE STRONG CAA. THE GOOD NEWS IS THAT THESE STRONGER WINDS WILL
NOT MAKE IT ALL THE WAY TO THE SURFACE AND EXPECT WESTERLY WINDS
TO VEER TO A MORE NORTHERLY DIRECTION BY THIS EVENING. THEY WILL
REMAIN IN THE 25 TO 35 MPH RANGE WITH OCCASIONAL GUSTS OVER 40
THIS MORNING AND AFTERNOON ACROSS EASTERN MONTANA.

THE ONE EXCEPTION IS THE LITTLE ROCKIES...DUE TO THE ELEVATION
IT WILL BE IMPACTED BY THE 50 TO 70 KNOT JET CORE THIS MORNING.
DECIDED TO LAUNCH A HIGH WIND WARNING FOR SOUTHWEST PHILLIPS
COUNTY UNTIL EARLY AFTERNOON. FRONTAL PASSAGE STILL LOOKS DRY
ALTHOUGH ALONG THE CANADIAN BORDER WE COULD SEE SOME LIGHT SNOW
THIS MORNING AND THEN SOME LIGHT SNOW ACROSS THE NORTHERN AND
WESTERN ZONES THIS AFTERNOON. SINCE THE FRONT IS SO DRY ANY SNOW
THAT DOES FALL WILL BARELY ACCUMULATE.

THIS EVENING STARTED A WIND CHILL ADVISORY AT 9 PM FOR THE WHOLE
CWA AND IT WILL LAST UNTIL NOON ON MONDAY. WIND CHILLS READING
WILL DROP TO 20 BELOW NORTH OF THE MISSOURI RIVER THIS EVENING
AND AFTER MIDNIGHT WIND CHILL READINGS WILL DROP BELOW 20 BELOW
SOUTH OF THE MISSOURI RIVER. SUNDAY NIGHT THROUGH TUESDAY CONTINUED
CHANCE OF LIGHT SNOW WITH OVERNIGHT LOW TEMPERTURES RANGING FROM
THE TEENS BELOW ZERO TO THE SINGLE DIGITS BELOW ZERO. HIGHS
DURING THE DAY IN THE SINGLE DIGITS ABOVE. RSMITH

.LONG TERM...TUESDAY NIGHT THROUGH SUNDAY...
THE EXTENDED BEGINS WITH THE MODELS IN GOOD AGREEMENT. A STRONG
850 MB TEMPERATURE GRADIENT IS IN PLACE OVER NORTHEAST MONTANA. IN
THE UPPER LEVELS A STRONG IS SET UP THROUGH THE REGION...AND COLD
SURFACE HIGH PRESSURE TO THE NORTH AND A SURFACE LOW TO THE WEST.
A VERY DEEP LAYER OF COLD AIR WILL BE IN PLACE OVER THE REGION.
THE COLD AIR IS MOVING THROUGH SO WILL KEEP POPS IN THE CHANCE
CATEGORY EARLY ON WEDNESDAY FOR LIGHT PRECIPITATION.

THURSDAY EARLY IN THE MORNING THE COLD AIR MAKES IT ALL THE WAY TO
THE ROCKY MOUNTAIN FRONT AND CREATES A GOOD OVER-RUNNING SNOW
EVENT. THE WORST LOOKS TO BE THE CENTRAL SECTION OF THE STATE
WHICH INCLUDES OUR SOUTHWEST ZONES. THE TROUBLE IS THAT THE GFS
AND EC DO NOT CARRY OUT THE EVENT THE SAME. PREFER THE EC HANDLING
OF THE BOUNDARY AND SURFACE WAVE THAT DEVELOPS ALONG IT. THE EC
SLIDES THE SURFACE WAVE/LOW DOWN THE BOUNDARY. THE GFS CRANKS UP
THE LOW OVER NORTHEAST MONTANA AND BRINGS A FAIR AMOUNT OF WARMER
AIR NORTHWARD INTO THE SYSTEM. IF THE GFS IS RIGHT SNOW AMOUNTS
WILL INCREASED OVER NORTHEAST MONTANA... THE EC...WHICH IS THE
PREFERRED MODEL...IS RIGHT THEN THE ISENTROPIC SURFACE IS NOT AS
STRONG AND THE BEST ADIABATIC OMEGA... DYNAMIC LIFT AND MOISTURE
OCCURS DURING THE DAY ON THURSDAY AND IS NOT PROLONGED KEEPING
SNOW AMOUNTS DOWN. DID INTRODUCE SNOW OVER LIGHT SNOW FOR THURSDAY
IN THE WESTERN AND CENTRAL ZONES AS CONFIDENCE INCREASES WITH THIS EVENT.

FRIDAY WILL KEEP CHANCE POPS GOING WITH THE ARCTIC BOUNDARY
FLOATING AROUND THE REGION... THEN THE WARMING BEGINS ON SATURDAY
WHICH SHOULD DRY UP THE PRECIPITATION AS THE ARCTIC BOUNDARY IS
SHOVED BACK INTO THE CENTRAL PRAIRIE PROVINCES. THIS WILL PROVIDE
A WARMER DAY ON SATURDAY FOR THE REGION AS A STRONG COLD FRONT
GEARS UP TO PASS THROUGH THE REGION ON SUNDAY. SATURDAY MAX
TEMPERATURES WILL BE TRICKY SINCE THE AMOUNT SNOW THAT FALLS
WEDNESDAY NIGHT THROUGH FRIDAY MID DAY ACROSS THE REGION WILL BE A
SIGNIFICANT FACTOR IN HOW QUICKLY IT WARMS UP.              PROTON

&&

.AVIATION...
VFR CONDITIONS TO START OFF THIS MORNING ACROSS THE REGION...THEN
CONDITIONS WILL DETERIORATE QUICKLY AFTER 12Z FROM NW TO SE ACROSS
THE REGION WITH THE FRONTAL PASSAGE. POST FRONTAL CONDITIONS WILL
BE DOMINATE MVFR CEILINGS... VFR VISIBILITIES... AND STRONG
NORTHWEST WINDS GUSTING TO 35 TO 40 KTS AT TIMES INTO THE EARLY
EVENING HOURS.             PROTON
