AVIATION SECTION UPDATED

.DISCUSSION...
THURSDAY THROUGH SATURDAY...A RIDGE OF HIGH PRESSURE WILL STAY
OVERHEAD FOR TODAY AND MUCH OF FRIDAY. TEMPERATURES DURING THIS
TIME WILL CONTINUE TO RISE. SKIES SHOULD BE RELATIVELY CLEAR
THROUGH THIS TIME FRAME. A WEAK PACIFIC STORM SYSTEM WILL WORK ITS
WAY INTO OUR AREA BY FRIDAY NIGHT AND SATURDAY. THE UPPER LEVEL
TROUGH WILL DOES NOT APPEAR TO BRING TOO MUCH MOISTURE INTO NORTH
CENTRAL AND CENTRAL MONTANA...HOWEVER SOME SLIGHT SNOW
ACCUMULATIONS ARE EXPECTED OVER THE ROCKY MOUNTAIN FRONT AND THE
MOUNTAINS IN SOUTHWEST MONTANA. THE LATEST MODEL RUNS HAVE
DECREASED THE AMOUNT OF PRECIP FROM THIS SYSTEM SO NO WINTER
HIGHLITES ARE EXPECTED AT THIS TIME FOR THIS STORM SYSTEM. SUK

SATURDAY NIGHT THROUGH TUESDAY NIGHT...UPPER LEVEL TROF THAT ARRIVES
EARLIER IN THE DAY ON SATURDAY SHOULD GRADUALLY WEAKEN ACROSS
CENTRAL AND SOUTHWEST MT BY SAT NIGHT AS MUCH OF ITS ENERGY AND
MOISTURE DIVE SOUTHWARD TOWARD THE FOUR CORNERS AREA.  RESIDUAL
MOISTURE AND SLIGHTLY UNSTABLE AIRMASS WILL GENERATE ISOLATED
SNOWSHOWERS OVER THE CENTRAL PLAINS AND SCATTERED SNOW SHOWERS OVER
THE SOUTHWEST PORTIONS OF THE CWA BEFORE TAPERING OFF EARLY SUN
MORNING.  AS THE TROF DEPARTS...LARGE PACIFIC HIGH PRESSURE RIDGE
WILL BUILD STEADILY OVER THE GREAT BASIN AND NRN ROCKIES STARTING
SUNDAY AFTN...PRODUCING MOSTLY CLEAR SKIES AND LIGHT WINDS THROUGH
TUESDAY.  EXPECT TEMPERATURES TO BE NEAR TYPICAL SEASONAL VALUES ON
SUN AS COOL AIRMASS ASSOCIATED WITH THE UPPER LEVEL TROF BEGINS TO
MODERATE.  PLEASANT SPRING-LIKE CONDITIONS RETURN WITH AFTN HIGHS
REACHING 10 TO 12 DEG ABOVE NORMAL ON MON AND 15 TO 18 DEG ABOVE
NORMAL ON TUES.  EXCEPTION WILL BE HILL AND NORTHERN BLAINE COUNTIES
WHERE CURRENT SNOWCOVER...THOUGH MELTING...WILL STILL BE SUFFICIENT
TO KEEP TEMPS ABOUT 10 TO 15 DEG COOLER THAN SURROUNDING AREAS.
WARANAUSKAS

WEDNESDAY AND THURSDAY...MODELS SHOW AN UPPER LEVEL TROUGH OVER THE
INTER-MOUNTAIN WEST. DOWNSLOPE FLOW ON WEDNESDAY WILL RESULT
IN MOSTLY DRY AND SEASONABLY MILD TEMPERATURES. BOTH GFS AND
ECMWF MODELS SHOW A PACIFIC COLD FRONT MOVING THROUGH WEDNESDAY
AFTERNOON...BRINGING GUSTY WEST TO NORTHWEST WINDS. TEMPERATURES
WILL COOL TO BELOW SEASONAL LEVELS OVER NORTH CENTRAL MONTANA AND
NEAR SEASONAL AVERAGE ACROSS THE SOUTHWEST BY THURSDAY. THERE
WILL ALSO BE ISOLATED SNOW SHOWERS ACROSS THE VALLEYS AND PLAINS
WITH SCATTERED SNOW SHOWERS OVER THE MOUNTAINS. WILLIAMSON DC
