1007 AM MST TUE JAN 26 2016

AVIATION SECTION UPDATED

.DISCUSSION...

TODAY...MAIN CONCERN FOR TODAY IS A POSSIBLE HIGH WIND EVENT
TONIGHT ACROSS THE NORTHERN ROCKIES. SITUATION CONTINUES TO LOOK
MARGINAL AND HAVE DECIDED NOT TO ISSUE ANY HIGH LIGHTS. UPDATED TO
RAISE TEMPS A FEW DEGREES OVER PORTIONS OF THE CENTRAL AND
NORTHERN ZONES. ALSO RAISED POPS OVER THE CONTDVD FOR TONIGHT.
ZELZER

&&

.AVIATION...UPDATED 1706Z.

A HIGH PRESSURE RIDGE WILL GENERALLY KEEP THE AIRMASS DRY. BRISK
SURFACE WINDS OVER THE ROCKIES AND ADJACENT PLAINS WILL STRENGTHEN
FURTHER THIS EVENING AS A SHORTWAVE MOVES INTO THE RIDGE. SUSTAINED
WINDS OF 30-35 KTS GUSTING TO 60-70 KTS ARE EXPECTED OVER THE
NORTHERN ROCKIES. VFR CONDITIONS WILL PREVAIL THROUGH THE NEXT
24HOURS.

&&

.PREV DISCUSSION...
/ISSUED 635 AM MST TUE JAN 26 2016/

TODAY THROUGH THURSDAY...A LARGE AMPLITUDE UPPER LEVEL RIDGE
POSITIONED OVER THE WESTERN U.S. WILL DRIFT INTO WESTERN MONTANA
TODAY. PACIFIC MOISTURE STREAMING OVER THE TOP OF THE RIDGE
WILL BRING INCREASING HIGH CLOUDS INTO THE STATE. A SHORTWAVE TROUGH
UPSTREAM OF THE RIDGE AXIS WILL CROSS WESTERN CANADA TODAY AND
TONIGHT...CAUSING A LEE TROUGH TO DEVELOP AND STRENGTHEN THE SURFACE
PRESSURE GRADIENT. WIND GUSTS UP TO 50 MPH ARE POSSIBLE TODAY ALONG
THE ROCKY MOUNTAIN FRONT...WITH 30 MPH GUSTS EXTENDING ONTO THE N-
CENTRAL PLAINS. WINDS TAPER EARLY WEDNESDAY AS THE CLIPPER DEPARTS
TO THE EAST AND HIGH PRESSURE BRIEFLY STRENGTHENS OVER THE NORTHERN
ROCKIES. SURFACE WINDS INCREASE ONCE AGAIN ON THURSDAY AS THE
RIDGE FLATTENS AND A STRONG ZONAL JET STREAM EXTENDS INTO INTO
WESTERN MONTANA. TEMPERATURES WILL REACH INTO THE MID 50S THURSDAY AS
WIND GUSTS NEAR 70 MPH ALONG THE ROCKY MOUNTAIN FRONT AND AROUND 45
MPH AT TIMES ACROSS THE PLAINS. HIGH WIND HEADLINES ARE NOT
ANTICIPATED AT THIS TIME...BUT WILL CONTINUE TO MONITOR CLOSELY
WITH UPDATED MODEL GUIDANCE. FAIR AND SEASONABLY COOL WEATHER
PREVAILS IN THE SOUTHWEST...WITH A FEW MOUNTAIN SNOW SHOWERS
POSSIBLE TUESDAY NIGHT AND WEDNESDAY. PN

THURSDAY NIGHT THROUGH TUESDAY...MODELS REMAIN IN GOOD AGREEMENT
BRINGING A STRONG UPPER LEVEL JET AND ABUNDANT PACIFIC MOISTURE
INTO THE REGION THURSDAY NIGHT AND FRIDAY. BY SATURDAY MORNING THE
UPPER LEVEL JET WILL SAG SOUTHWARD BRINGING AN ATMOSPHERIC RIVER
INTO CALIFORNIA AND LEAVING MONTANA IN AN UNSETTLED NORTHWESTERLY
FLOW. MEDIUM RANGE MODELS CONTINUE TO HAVE SIGNIFICANT DIFFERENCES
IN THEIR SOLUTIONS AS THEY SHIFT THE STORM TRACK SOUTHWARD. AS A
RESULT, CONFIDENCE IN THE CURRENT FORECAST IS FAIRLY LOW. HAVE
TRENDED TEMPERATURES COOLER WITH THE EXPECTATION THAT LOW LEVEL
FLOW WILL BECOME NORTHERLY AS SURFACE LOW PRESSURE DEVELOPS IN
EITHER THE GREAT BASIN OR DESERT SOUTHWEST. HAVE ALSO TRENDED POPS
BACK TOWARD CLIMATOLOGY GIVEN THE EXPECTATION FOR AN UNSETTLED
REGIME SETTING UP NORTH OF THE MAIN STORM TRACK. MPJ
