DISCUSSION
THROUGH SUNDAY...
A SHORTWAVE AND ASSOCIATED COLD FRONT PUSHING THROUGH THE REGION
TODAY BROUGHT RAIN/SNOW SHOWERS TO THE LOWER ELEVATIONS, SNOW TO
THE MOUNTAINS, COOLER TEMPERATURES AND BREEZY NORTHWEST WINDS.
SHOWERS WILL BE CAPABLE OF BRIEF REDUCTIONS IN VISIBILITY, BUT FOR
THE MOST PART, LITTLE IN THE WAY OF SNOW ACCUMULATIONS IS EXPECTED
FOR THE LOWER ELEVATIONS. AS THE WAVE CONTINUES TO SLIDE EAST
TONIGHT, EXPECT THE ISOLATED TO SCATTERED SHOWERS (15-30% CHANCE)
TO GRADUALLY DIMINISH, WITH SOME LINGERING FLURRIES POSSIBLE
OVERNIGHT. WINDS WILL GRADUALLY DECREASE OVERNIGHT AS WELL. A COOL
NIGHT IS ON TAP WITH TEMPERATURES DOWN INTO THE 20S TO LOWER 30S.
MAINLY DRY, BUT COOL CONDITIONS CAN BE EXPECTED FOR TUESDAY AS AN
UPPER TROUGH DIGS TO THE EAST INTO THE CENTRAL US, PUTTING THE
REGION UNDER NW FLOW. TEMPERATURES IN THE 40S CAN BE EXPECTED FOR
MOST AREAS. BY LATE TUESDAY INTO WEDNESDAY, RIDGING BUILDS BACK
OVER THE REGION BRINGING SLIGHTLY WARMER CONDITIONS (HIGHS IN THE
50S). A SHORTWAVE CUTTING ACROSS SOUTHERN CANADA WILL DRAG AN
ASSOCIATED COLD FRONT THROUGH THE AREA WEDNESDAY EVENING/NIGHT
BRINGING VERY LOW CHANCES (15% OR LESS) FOR PRECIPITATION AND
NORTHWEST WINDS. AS THE SHORTWAVE WRAPS UP INTO AN UPPER LOW OVER
THE NORTHERN PLAINS, PRESSURE GRADIENTS LOOK TO TIGHTEN OVER
EASTERN MT, BRINGING BREEZY NW WINDS. WARMER AND DRIER CONDITIONS
LOOK TO RETURN FRIDAY INTO SATURDAY AS RIDGING BUILDS OVER THE
REGION. ALTHOUGH THERE IS UNCERTAINTY IN THE OVERALL FLOW,
ENSEMBLES CONTINUE TO POINT TO A POTENTIAL WEATHER SYSTEM MOVING
INTO THE REGION BY SUNDAY. ALONG WITH PRECIPITATION CHANCES, THE
SYSTEM COULD BRING A WINDY PERIOD. THINGS TO WATCH IN THE COMING
DAYS. STP
AVIATION
VFR CONDITIONS ARE EXPECTED THIS EVENING AND OVERNIGHT. ISOLATED

THE MOUNTAINS WILL CONTINUE THIS EVENING. LOOK FOR GUSTY
