...LOW PRESSURE SYSTEM WILL BRING WIDESPREAD MOUNTAIN SNOW ACROSS
THE WESTERN U.S. AND A SWATH OF MODERATE TO LOCALLY HEAVY SNOWFALL
ACROSS THE NORTH-CENTRAL PLAINS THROUGH FRIDAY...
...CRITICAL FIRE WEATHER CONDITIONS EXPECTED TO CONTINUE ACROSS
THE SOUTHERN HIGH PLAINS...
...COLDER AND DRIER AIR TO ARRIVE ACROSS THE EAST BUT WITH SOME
AREAS OF SNOWFALL DOWNWIND OF THE GREAT LAKES AND INTO THE CENTRAL
AND NORTHERN APPALACHIANS...
A BROAD LOW PRESSURE SYSTEM CURRENTLY DEVELOPING OVER THE INTERIOR
WESTERN U.S. WILL BRING WIDESPREAD UNSETTLED WEATHER EASTWARD INTO
THE MID-SECTION OF THE COUNTRY THROUGH THE NEXT COUPLE OF DAYS.
IN THE SHORT TERM, WIDESPREAD MOUNTAIN SNOW WILL AFFECT THE GREAT
BASIN EASTWARD INTO THE NORTHERN AND CENTRAL ROCKIES INTO FRIDAY.
THE LOW PRESSURE SYSTEM WILL BEGIN TO MOVE ACROSS THE CENTRAL
PLAINS. COLDER AIR WILL SUPPORT A SWATH OF MODERATE TO LOCALLY
HEAVY SNOWFALL NORTH OF THE TRACK OF THE LOW PRESSURE CENTER FROM
THE NORTHERN ROCKIES EASTWARD ACROSS THE NORTH-CENTRAL PLAINS
WHERE UP TO LOCALLY A FOOT OF NEW SNOW IS POSSIBLE ON FRIDAY.
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. IN ADDITION, A PIECE OF UPPER-LEVEL
DISTURBANCE EMBEDDED WITHIN THE BROAD SYSTEM WILL BRING
LOWER-ELEVATION RAIN AND MOUNTAIN SNOW ACROSS THE SOUTHWESTERN
U.S. THROUGH FRIDAY, REACHING INTO THE FOUR CORNERS BY FRIDAY
NIGHT. THE MOUNTAIN SNOW WILL THEN ADVANCE FURTHER EAST ACROSS
THE SOUTHERN ROCKIES ON SATURDAY. HEAVIEST SNOWFALL OF 1 TO 2
FEET CAN BE EXPECTED ALONG THE MOGOLLON RIM AND THE SAN JUAN
MOUNTAINS IN THE ROCKIES, AS WELL AS ACROSS THE HIGHER TERRAIN OF
THE CENTRAL ROCKIES AND ALONG THE WASATCH OF UTAH.
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 CONTINUE TO BE
USHERED INTO THE AREA BEHIND A SLOWLY DEPARTING DEEP CYCLONE
ACROSS THE CANADIAN MARITIMES. THE PROXIMITY OF THE DEEP LOW WILL
ALLOW THE RAIN TO CHANGE OVER TO LIGHT SNOW TONIGHT ACROSS
NORTHERN MAINE, FOLLOWED BY A PERIOD OF LIGHT TO MODERATE SNOW
THROUGH FRIDAY MORNING AS A FINAL LOW PRESSURE WAVE IS FORECAST TO
PASS JUST TO THE EAST. A REINFORCING SHOT OF COLDER AIR WILL BE
ACCOMPANIED WITH AREAS OF SNOW SHOWERS TO BRING LOCALLY SEVERAL
INCHES OF LAKE-ENHANCED SNOWFALL DOWNWIND OF THE GREAT LAKES AND
INTO THE UPSLOPE AREAS OF THE CENTRAL AND NORTHERN APPALACHIANS ON
FRIDAY.
