ELEVATIONS OF THE GREAT BASIN...

NORTHERN PLAINS ON MONDAY...
...HEAVY SNOW OVER PARTS OF THE SIERRA NEVADA MOUNTAINS ON

A STRONG WINTER STORM AND COLD FRONT WILL MOVE INTO THE NORTHWEST
ON SUNDAY AND PROGRESS SOUTHEASTWARD INTO THE NORTHERN ROCKIES ON
MONDAY. HEAVY MOUNTAIN SNOW OVER THE CASCADES WILL IMPACT THE
PASSES BY LATE SUNDAY, WITH GREATER THAN 80% CHANCE OF AT LEAST A
FOOT OF SNOW ABOVE 1500FT THROUGH EARLY TUESDAY. IN ADDITION,
SNOWFALL WILL SOMETIMES BECOME HEAVY, WITH RATES OF 1-2 INCHES PER
HOUR, ALONG WITH WINDY CONDITIONS, CREATING AREAS OF BLOWING SNOW
AND DRIFTING SNOW AND SIGNIFICANTLY REDUCING VISIBILITY.
FURTHERMORE, SNOW SQUALLS ARE LIKELY ALONG THE PATH OF THE COLD
FRONT ON MONDAY OVER THE NORTHERN INTERMOUNTAIN REGION/ROCKIES,
WHICH COULD CREATE A RAPID DROP IN VISIBILITY AND ICING ON
ROADWAYS, LEADING TO DANGEROUS TRAVEL. ADDITIONALLY, MUCH COLDER
AIR BEHIND THE STRONG COLD FRONT WILL DROP TEMPERATURES INTO THE
TEENS AND COLDER BY TUESDAY MORNING.
FURTHER, THE SYSTEM WILL PRODUCE COASTAL RAIN OVER THE NORTHWEST,
WITH SNOW LEVELS LOWERING TO NEAR SEA LEVEL AFTER THE FRONT
PASSES. OVERNIGHT SUNDAY, RAIN WILL MOVE INTO PARTS OF CALIFORNIA,
WITH HIGHER-ELEVATION SNOW. MOREOVER, ON MONDAY, HEAVY SNOW WILL
IMPACT THE SIERRA NEVADA MOUNTAINS. A WAVE OF LOW PRESSURE WILL
MOVE OVER PARTS OF THE NORTHERN PLAINS BY MONDAY EVENING AS SNOW
DEVELOPS OVER THE REGION. THERE IS ALSO A RISK OF RAIN/FREEZING
RAIN MOVING OVER PARTS OF THE UPPER MISSISSIPPI VALLEY.
MEANWHILE, MOISTURE FROM THE WESTERN GULF OF MEXICO WILL STREAM
NORTHWARD OVER THE SOUTHERN PLAINS, MIDDLE/LOWER MISSISSIPPI
VALLEY, AND OHIO VALLEY. THE MOISTURE WILL AID IN CREATING
SCATTERED LIGHT RAIN SHOWERS OVER PARTS OF THE OHIO VALLEY
OVERNIGHT SUNDAY INTO MONDAY. BY TUESDAY, THE MOISTURE WILL
PRODUCE SHOWERS AND THUNDERSTORMS OVER PARTS OF THE OHIO VALLEY.
FURTHERMORE, UPPER-LEVEL ENERGY WILL ASSIST IN CREATING LIGHT SNOW
OVER PARTS OF THE NORTHEAST OVERNIGHT SUNDAY INTO MONDAY EVENING.
