...UPDATE TO AVIATION...

.DISCUSSION...

TONIGHT THROUGH FRIDAY...AN UPPER LEVEL HIGH PRESSURE RIDGE OVER
THE WESTERN US WILL BE FLATTENED AS A SHORTWAVE AND JET OF
STRONGER WINDS APPROACH THE ROCKIES TONIGHT. WINDS WILL INCREASE
THIS AFTERNOON AND TONIGHT AND BEGIN TO WEAKEN AGAIN TOWARDS
THURSDAY MORNING. A HIGH WIND WARNING HAS BEEN ISSUED FOR THE
NORTHERN ROCKIES...WHICH ALSO HAS A WINTER STORM WARNING ABOVE
5000 FEET. HIGH WINDS WILL KEEP TEMPS MODERATE ACROSS THE ROCKIES
TONIGHT BUT TEMPS FARTHER EAST WILL AGAIN BE COLD. TEMPERATURES FOR
THURSDAY WILL ALSO BE TRICKY AS A CANADIAN COLD FRONT PUSHES INTO
THE PLAINS. THE BOUNDARY WILL BE MOVING TOWARDS GTF BUT WHERE IT
COMES TO A HALT IS QUESTIONABLE. ANOTHER WEAK SHORTWAVE WILL
APPROACH THE ROCKIES THURSDAY NIGHT. WARM AIR ALOFT ALONG WITH
COLD SURFACE TEMPS ACROSS THE EASTERN ZONES BRING THE POSSIBILITY OF
FREEZING RAIN. THE CHANCE APPEARS LOW BUT WILL HAVE A MENTION IN
THE WEATHER GRIDS. THE SHORTWAVE WILL MOVE EAST OF THE ZONES
FRIDAY AND HIGH PRESSURE WILL AGAIN BUILD OVER THE ZONES. THE
SHORTWAVES WILL HOLD BACK SOME OF THE WARMING THAT WOULD OTHERWISE
BE EXPECTED FROM THE CONTINUED PRESENCE OF THE HIGH PRESSURE
RIDGE. ZELZER

FRIDAY NIGHT THROUGH WEDNESDAY...MEDIUM RANGE MODELS CONTINUING TO
SHOW SOME CONSISTENCY THOUGH DETAILS REGARDING PLACEMENT OF COLD
INTRUSIONS AND SNOW BANDS REMAIN DIFFICULT. GENERALLY THE PATTERN
WILL BE ONE WITH MOIST NORTHWEST FLOW ALOFT PERSISTING OVER THE
AREA AND SHORT WAVE ENERGY MOVING THROUGH FROM TIME TO TIME. SNOW
THAT DEVELOPS OVER THE AREA FRIDAY NIGHT MOVES EAST ON SATURDAY
LEAVING BEHIND SCATTERED SNOW SHOWERS AND COOL TEMPERATURES ACROSS
THE NORTH. SHORT WAVE ENERGY MOVING INTO WESTERN MONTANA SUNDAY
WILL BRING ANOTHER ROUND OF SNOW TO THE ROCKY MOUNTAIN FRONT AND
ADJACENT PLAINS TO THE EAST. SCATTERED SNOW REMAINS A POSSIBILITY
MONDAY AS COLD AIR REMAINS OVER PORTIONS OF CENTRAL AND NORTHEAST
MONTANA. ANOTHER SHORT WAVE APPROACHES WESTERN MONTANA TUESDAY AND
BRINGS INCREASING CHANCES OF SNOW TO THE ROCKIES BEFORE SPREADING
EAST DURING THE DAY. SCATTERED LIGHT SNOW WILL CONTINUE WEDNESDAY.
TEMPERATURES WILL REMAIN BELOW SEASONAL AVERAGES WITH ONLY
PORTIONS OF SOUTHWEST MONTANA HAVING ANY HOPE OF SEEING SOME
AFTERNOON HIGHS ABOVE FREEZING.
