1035 AM MST THU JAN 12 2012

UPDATED AVIATION DISCUSSION

.DISCUSSION...

TODAY THROUGH SATURDAY...INCREASING CLOUDS AND WIND ASSOCIATED WITH
WEAK SHORTWAVE ENERGY IS EXPECTED FOR TODAY. WITH LIMITED MOISTURE
THERE WILL BE LITTLE IF ANY CHANCE FOR PRECIPITATION. TEMPERATURES
WILL CONTINUE TO TREND WARMER AS AN UPPER-LEVEL RIDGE MOVES OVER THE
AREA. HIGH TEMPERATURES TODAY WILL BE AROUND TO SLIGHTLY ABOVE
SEASONAL AVERAGES. SOME AREAS OF BLOWING SNOW ARE POSSIBLE THIS
MORNING ACROSS THE ROCKY MOUNTAIN FRONT AND ADJACENT
PLAINS...HOWEVER WARMING TEMPERATURES WILL LIMIT BLOWING SNOW BY
THIS AFTERNOON. RIDGE WILL FLATTEN AS IT MOVES OVER THE NORTHERN
ROCKIES ON FRIDAY WHICH WILL PROMOTE STRONGER WINDS...THOUGH AM NOT
EXPECTING HIGH WINDS. AS THE RIDGE ALOFT FLATTENS AND BECOMES MORE
WESTERLY THE POTENTIAL FOR STRONG WINDS WILL INCREASE THOUGH MODELS
INDICATE MARGINAL HIGH WIND CRITERIA. STRONGEST WINDS WILL BE ON
FRIDAY NIGHT AND SATURDAY ALONG THE ROCKY MOUNTAIN FRONT AS A
LEE-SIDE TROUGH DEVELOPS EAST OF THE DIVIDE AND SHORTWAVE ENERGY
PROPAGATES THROUGH THE FLOW. WILL CONTINUE TO MONITOR THIS TREND FOR
ANY POTENTIAL HIGHLIGHTS BUT CONFIDENCE IS LOW TO MODERATE REGARDING
DURATION AND INTENSITY OF WINDS. MAINLY DRY CONDITIONS WILL PERSIST
THROUGH SATURDAY WITH ONLY A SLIGHT CHANCE ON THE HIGHER PEAKS OF
THE ROCKY MOUNTAIN FRONT ON SATURDAY. TEMPERATURES WILL BE WELL
ABOVE AVERAGE ON FRIDAY AND SATURDAY. MLV

SATURDAY NIGHT THROUGH THURSDAY...AN UPPER LEVEL LOW PRESSURE TROF
WILL BE MOVING OVER THE WEST COAST SATURDAY NIGHT. THIS WILL FLATTEN
THE RIDGE OVER THE REGION AND INCREASE MOISTURE FROM THE WEST.
STRONG WINDS ALOFT WILL BRING VERY STRONG SURFACE WINDS ACROSS THE
NORTHERN ROCKIES AND PLAINS. AN ASSOCIATED SURFACE LOW PRESSURE
CENTER WILL MOVE ACROSS SOUTHERN ALBERTA SUNDAY AND BRING A COLD
FRONT SOUTH ACROSS THE BORDER DURING THE DAY. THIS WILL BRING
WIDESPREAD SNOW ACROSS THE ZONES AS WELL AS SIGNIFICANTLY COLDER
TEMPERATURES. A 1040 SURFACE PRESSURE HIGH WILL BE OVER NORTHERN
ALBERTA BY LATE MONDAY AND THIS WILL KEEP NORTHEAST TO EAST SURFACE
FLOW IN THE FORECAST AS IT MOVES EAST. THE LOW PRESSURE TROF WILL
MOVE EAST OF THE ZONES MONDAY NIGHT BUT DISTURBED FLOW TO THE WEST
WILL CONTINUE TO BRING MOISTURE ACROSS THE ROCKIES...AND WITH THE
CONTINUED NORTHEAST SURFACE FLOW...THE AIRMASS WILL REMAIN
RELATIVELY MOIST AND COOL.  ZELZER

.AVIATION...
UPDATED 1800Z.
HIGH PRESSURE WILL BUILD ALOFT FROM THE PACIFIC NW ACROSS THE
NORTHERN ROCKIES THROUGH THE NEXT 24 HRS...MAINTAINING DRY
CONDITIONS UNDER A NW FLOW ALOFT. VFR CONDITIONS WILL PREVAIL AT ALL
TAF SITES. HOENISCH
