VALID 12Z SAT MAR 16 2024 - 12Z MON MAR 18 2024
...HEAVY MOUNTAIN SNOW IMPACTS THE FOUR CORNERS AND SOUTHERN
ROCKIES THIS WEEKEND...
...SEVERE THUNDERSTORMS AND HEAVY RAIN POSSIBLE ACROSS SOUTHERN
TEXAS AND ALONG THE GULF COAST...
...MILD WEATHER CONTINUES ACROSS THE PACIFIC NORTHWEST AND EAST
COAST...
THE LINGERING CLOSED UPPER LOW LOCATED OVER THE DESERT SOUTHWEST
IS FORECAST TO REMAIN MOSTLY STATIONARY THIS WEEKEND AND PRODUCE
THE CONTINUED THREAT OF HEAVY MOUNTAIN SNOW FROM THE FOUR CORNERS
REGION TO THE SOUTHERN ROCKIES. IN PARTICULAR, THE HIGH TERRAIN OF
CENTRAL/SOUTHERN UTAH AS WELL AS THE SAN JUAN AND SANGRE DE CRISTO
MOUNTAINS OF COLORADO AND NEW MEXICO CAN EXPECT TREACHEROUS
CONDITIONS DUE TO HEAVY SNOW. ADDITIONAL SNOWFALL ACCUMULATIONS
OVER A FOOT ARE EXPECTED FOR PARTS OF THE SOUTHERN ROCKIES THROUGH
MONDAY, WITH WINTER STORM WARNINGS AND WINTER WEATHER ADVISORIES
REMAINING IN EFFECT.
MEANWHILE, A STALLING COLD FRONT EXTENDING FROM THE SOUTHEAST TO
SOUTHERN TEXAS WILL LEAD TO AT LEAST A FEW MORE DAYS OF STORMINESS
FOR THE LONE STAR STATE AND REMAINING GULF COAST REGION. THE
GREATEST SEVERE WEATHER THREAT EXISTS TODAY ACROSS SOUTH-CENTRAL
TEXAS AND THE MIDDLE TEXAS COAST, WHERE THE STORM PREDICTION
CENTER HAS HIGHLIGHTED A SLIGHT RISK (LEVEL 2 OF 5) FOR SEVERE
THUNDERSTORMS. LARGE HAIL, DAMAGING WINDS, AND ISOLATED TORNADOES
ARE POSSIBLE WITHIN THE STRONGEST STORMS. INTENSE RAINFALL RATES
FALLING OVER SATURATED GROUND MAY ALSO LEAD TO FLASH FLOODING AND
STANDING WATER IN URBAN AREAS THROUGHOUT SIMILAR PORTIONS OF TEXAS
AND STRETCHING INTO FAR SOUTHWEST LOUISIANA. BY SUNDAY, SHOWER AND
THUNDERSTORM ACTIVITY IS EXPECTED TO STRETCH ALONG MOST OF THE
GULF COAST, WITH ISOLATED TO SCATTERED CHANCES FOR SEVERE WEATHER
AND FLASH FLOODING. GIVEN RECENT RAINFALL, PARTS OF SOUTHWEST
LOUISIANA AND SOUTHEAST TEXAS HAVE BEEN DESIGNATED AS HAVING A
SLIGHT RISK (LEVEL 2 OF 4) FOR EXCESSIVE RAINFALL.
THE OTHER NOTABLE SYSTEM TO IMPACT THE CONUS THROUGH EARLY NEXT
WEEK IS FORECAST TO CLIP THE GREAT LAKES AND NORTHERN NEW ENGLAND,
PRODUCING MOSTLY LIGHT RAIN AND SNOW SHOWERS AS WELL AS GUSTY
WINDS AND COOLER TEMPERATURES. LOCALLY HEAVY SNOW IS POSSIBLE
DOWNWIND OF THE GREAT LAKES ON SUNDAY AND MONDAY. BEFORE THE
CHILLY AND BELOW AVERAGE AIRMASS PROGRESSES INTO THE EASTERN THIRD
OF THE NATION ON MONDAY, MILD AFTERNOON TEMPERATURES INTO THE 60S
AND 70S CAN BE EXPECTED THIS WEEKEND IN THE EAST. MORE
IMPORTANTLY, THE COLD AIRMASS ON THE WAY WILL CONTAIN A MORNING
FROST/FREEZE THREAT ON MONDAY THROUGHOUT THE MIDWEST AND OHIO
VALLEY AS LOWS DIP INTO THE 20S AND 30S.
UPPER RIDING ANCHORED OVER THE NORTHWEST WILL CONTINUE THE WARM
AND DRY PATTERN THROUGHOUT THE PACIFIC NORTHWEST AND NORTHERN
GREAT BASIN, EXPANDING INTO THE NORTHERN HIGH PLAINS ON MONDAY.
HIGHS INTO THE 60S AND 70S ARE FORECAST, WHICH COULD BREAK A FEW
DAILY HIGH TEMPERATURE RECORDS.
