...HEAVY MOUNTAIN SNOW CONTINUES THROUGHOUT THE FOUR CORNERS
REGION INTO THIS WEEKEND...
...SEVERE THUNDERSTORM AND EXCESSIVE RAINFALL CHANCES SHIFT SOUTH
INTO THE SOUTHEAST AND GULF COAST STATES...
...MILD WEATHER CONTINUES ACROSS THE PACIFIC NORTHWEST AND EAST
COAST...
A MEANDERING CLOSED UPPER LOW SPINNING OVER THE DESERT SOUTHWEST
WILL CONTINUE TO FUNNEL MOISTURE NORTHWARD INTO THE FOUR CORNERS
REGION AND CREATE ADDITIONAL CHANCES FOR HEAVY MOUNTAIN SNOW
THROUGH THE WEEKEND. SNOW CHANCES WILL DIMINISH TODAY ACROSS THE
CENTRAL/SOUTHERN HIGH PLAINS AS UPSLOPE FLOW WEAKENS, BUT
MOUNTAINOUS TERRAIN OF THE CENTRAL AND SOUTHERN ROCKIES CAN EXPECT
AN ADDITIONAL 1 TO 2 FEET OF SNOW THROUGH SUNDAY. THE HIGHER
ELEVATIONS OF SOUTHERN UTAH AND ARIZONA CAN ALSO EXPECT SNOWFALL
ACCUMULATIONS OVER A FOOT, WHICH WILL CREATE HAZARDOUS DRIVING
CONDITIONS. WINTER STORM WARNINGS AND WINTER WEATHER ADVISORIES
REMAIN IN EFFECT FOR THESE REGIONS.
FARTHER EAST, WAVES OF LOW PRESSURE AND AN ASSOCIATED COLD FRONT
ARE FORECAST TO SLIDE SOUTH AND EAST TODAY WHILE STRETCHING FROM
THE MID-ATLANTIC TO THE SOUTHERN PLAINS. HEAVY RAIN AND SCATTERED
THUNDERSTORMS WILL ACCOMPANY THIS SYSTEM, WITH THE GREATEST
CHANCES FOR SEVERE WEATHER AND/OR FLASH FLOODING LOCATED ACROSS
PARTS OF THE MID-SOUTH AND SOUTH-CENTRAL TEXAS. FOR THESE AREAS,
THUNDERSTORMS COULD BE STRONG ENOUGH TO CONTAIN DAMAGING WIND
GUSTS AND ISOLATED TORNADOES. MEANWHILE, THE PRIMARY RISK ACROSS
SOUTH-CENTRAL TEXAS IS EXPECTED TO BE ASSOCIATED WITH LARGE HAIL
AND SCATTERED FLASH FLOODING. BY THIS WEEKEND, THE AFOREMENTIONED
FRONTAL BOUNDARY IS FORECAST TO STALL ALONG THE GULF COAST AND
SOUTHERN TEXAS, RESULTING IN ADDITIONAL CHANCES FOR HEAVY RAIN
THAT COULD LEAD TO SCATTERED FLOODING CONCERNS FROM SOUTH-CENTRAL
TEXAS TO SOUTHERN MISSISSIPPI.
THE OTHER NOTABLE WEATHER SYSTEM TO IMPACT THE LOWER 48 WILL BE A
POTENT LOW PRESSURE SYSTEM PASSING TO THE NORTH OF THE GREAT LAKES
ON SATURDAY AND NEARING MAINE ON SUNDAY. THE GREATEST IMPACTS ARE
ANTICIPATED TO BE ASSOCIATED WITH GUSTY WINDS ACROSS THE GREAT
LAKES AND DECREASING TEMPERATURES THROUGHOUT THE UPPER MIDWEST BY
SUNDAY. ADDITIONALLY, PERIODS OF LAKE EFFECT SNOW COULD BE LOCALLY
HEAVY ACROSS THE U.P. OF MICHIGAN DOWNWIND OF LAKE SUPERIOR.
OTHERWISE, STRONG SOUTHERLY FLOW ON THE EASTERN SIDE OF THIS
SYSTEM WILL KEEP MUCH OF THE EAST COAST MILD WITH HIGH
TEMPERATURES MAINLY IN THE 60S AND 70S. THE OTHER WARM SPOTS OVER
THE NEXT FEW DAYS INCLUDE THE PACIFIC NORTHWEST AND SOUTHEAST,
WHERE A FEW DAILY RECORD HIGHS ARE POSSIBLE. PARTS OF WESTERN
WASHINGTON AND OREGON MAY SEE HIGHS INTO THE MID-70S, WHILE
MID-TO-UPPER 80S ARE FOUND THROUGHOUT THE SUNSHINE STATE.
