WEST, THE ROCKIES, AND THE CENTRAL PLAINS THROUGH THE END OF THE
WEEK...
...CRITICAL FIRE WEATHER CONDITIONS EXIST ACROSS THE SOUTHERN HIGH
PLAINS...
...COLDER AND DRIER AIR TO ARRIVE ACROSS THE EAST ALONG WITH SOME

A PACIFIC STORM SYSTEM CONTINUES TO EDGE INLAND ACROSS CALIFORNIA
AND THIS WILL MOVE ADVANCE EAST ACROSS THE INTERMOUNTAIN WEST
TODAY AND THEN THE ROCKIES BY THIS EVENING. WHILE THERE WILL BE
ADDITIONAL AREAS OF LOWER ELEVATION RAINFALL, THE ARRIVAL OF
COLDER TEMPERATURES WITH THE ASSOCIATED UPPER-LEVEL TROUGH
PIVOTING ACROSS THE REGION WILL SET THE STAGE FOR HEAVY SNOWFALL
ACROSS THE HIGHER ELEVATIONS. AS MUCH AS 1 TO 2 FEET OF NEW
SNOWFALL IS EXPECTED ACROSS THE MOGOLLON RIM OF ARIZONA, THE
WASATCH OF UTAH, THE HIGH COUNTRY OF WESTERN COLORADO AND ALSO
PORTIONS OF WYOMING AS LOW PRESSURE ADVANCES EAST TOWARD THE
CENTRAL ROCKIES AND BRINGS MOISTURE TRANSPORT AND UPSLOPE FLOW TO
THE HIGHER TERRAIN.
GOING THROUGH TONIGHT AND FRIDAY MORNING, LOW PRESSURE WILL BE
ORGANIZING OVER THE CENTRAL HIGH PLAINS AND THIS WILL ALLOW HEAVY
SNOWFALL THAT WILL BE IMPACTING LARGE AREAS OF WYOMING TO DEVELOP
OFF TO THE EAST ACROSS AREAS OF SOUTHWEST SOUTH DAKOTA AND MUCH OF
WESTERN AND NORTHERN NEBRASKA WHERE AS MUCH AS 6 TO 12 INCHES OF
SNOW WILL BE POSSIBLE THROUGH FRIDAY MORNING. SNOW WILL EXTEND AS
FAR EAST AS PORTIONS OF THE MIDWEST INCLUDING IOWA AND NORTHERN
ILLINOIS WHERE AT LEAST A FEW INCHES OF ACCUMULATION CAN BE
EXPECTED.
FARTHER SOUTH OVER THE SOUTHERN HIGH PLAINS ON THE WARMER AND
DRIER SIDE OF THIS STORM SYSTEM, THERE WILL ONCE AGAIN BE CONCERNS
FOR WILDFIRE ACTIVITY, AS A COMBINATION OF LOW RELATIVE HUMIDITIES
AND GUSTY WINDS IS EXPECTED TO ONCE AGAIN RESULT IN CRITICAL FIRE
WEATHER CONDITIONS WHICH WILL PRIMARILY ENCOMPASS MUCH OF EASTERN
AND SOUTHERN NEW MEXICO AND OUT INTO WESTERN TEXAS.
ACROSS THE EASTERN U.S., COLDER AND DRIER AIR WILL BE ARRIVING IN
THE WAKE OF THE DEEP LOW CENTER THAT MOST RECENTLY IMPACTED THE
PLAINS, MIDWEST AND GREAT LAKES. HOWEVER, AT LEAST FOR TODAY, A
FRONT WILL STILL BE GRADUALLY CLEARING AREAS OF NORTHERN NEW
ENGLAND, AND WITH ANOTHER WAVE OF LOW PRESSURE LIFTING ALONG THIS
FRONT, THERE WILL BE SOME ADDITIONAL AREAS OF HEAVY RAINFALL. MUCH
COLDER TEMPERATURES AND AREAS OF SNOW SHOWERS WILL ARRIVE BEHIND
THE FRONTAL PASSAGE, AND LOCALLY SEVERAL INCHES OF LAKE-ENHANCED
SNOWFALL CAN BE EXPECTED DOWNWIND OF THE GREAT LAKES AND INTO THE
UPSLOPE AREAS OF THE CENTRAL AND NORTHERN APPALACHIANS TODAY AND
FRIDAY.
