...HEAVY SNOW AND GUSTY WINDS WILL FOSTER HAZARDOUS TRAVEL
CONDITIONS FOR PORTIONS OF THE NORTHERN AND CENTRAL ROCKIES AS
WELL AS THE NEARBY HIGH PLAINS FOR THE HOLIDAY WEEKEND...
...VERY COLD AIR WILL DROP DOWN ACROSS THE CENTRAL PLAINS, WITH
LARGE SECTIONS OF THE COUNTRY EXPECTED TO SEE BELOW NORMAL
TEMPERATURES AND DRY CONDITIONS THIS HOLIDAY WEEKEND...
A STORM SYSTEM TRAVERSING THE INTERMOUNTAIN WEST ON THIS
THANKSGIVING DAY WILL GRADUALLY BRING A SWATH OF MODERATE TO HEAVY
SNOW FOR AREAS OF THE NORTHERN AND CENTRAL ROCKIES OVER THE NEXT
COUPLE OF DAYS, AND THIS WILL ALSO BEGIN TO SPILL OUT INTO
PORTIONS OF THE HIGH PLAINS GOING INTO THE REMAINDER OF THE
HOLIDAY WEEKEND. AS MUCH AS 6 TO 12 INCHES OF SNOW CAN BE EXPECTED
ACROSS THE HIGH PLAINS WITH SOME OF THE HIGHER TERRAIN OF THE
ROCKIES LIKELY TO SEE ACCUMULATIONS OF AS MUCH AS 1 TO 2 FEET.
COINCIDING WITH THE HEAVY SNOWFALL THREAT WILL ALSO BE MUCH COLDER
TEMPERATURES AND GUSTY WINDS, AND ESPECIALLY ACROSS THE CENTRAL
PLAINS, AS A STRONG AREA OF HIGH PRESSURE DROPS DOWN FROM CANADA
AND ACROSS THE NORTHERN THIRD OF THE COUNTRY. SOME PARTS OF THE
CENTRAL PLAINS WILL SEE HIGH TEMPERATURES AS MUCH AS 15 TO 25
DEGREE BELOW NORMAL ON FRIDAY AND SATURDAY. A COMBINATION OF THE
HEAVY SNOW, GUSTY WINDS, AND VERY COLD TEMPERATURES WILL LIKELY
RESULT IN HAZARDOUS TRAVEL CONDITIONS WITH REDUCED VISIBILITIES
ALONG WITH SNOW-COVERED AND ICY ROADS. LOCALLY SOME FLASH FREEZE
CONDITIONS WILL BE POSSIBLE DUE TO THE EXPECTED RAPID DROP IN
TEMPERATURES.
MEANWHILE AS THE AXIS OF COLD HIGH PRESSURE CONTINUES TO EDGE
SOUTHWARD, BELOW NORMAL TEMPERATURES WILL ALSO FILTER DOWN INTO
MUCH OF THE SOUTH AND THE EASTERN U.S. WITH HIGH TEMPERATURES AS
MUCH AS 10 TO 15 DEGREES BELOW NORMAL HEADING THROUGH THE
REMAINDER OF THE HOLIDAY WEEKEND.
THERE IS NOT EXPECTED TO BE MUCH IN THE WAY OF RAINFALL ACROSS THE
COUNTRY OVER THE NEXT FEW DAYS, WITH THE ONLY EXCEPTIONS BEING
PARTS OF THE IMMEDIATE GULF COAST AND ACROSS THE FLORIDA PENINSULA
WHERE SOME LIGHT RAIN AND SHOWER ACTIVITY WILL BE POSSIBLE.
THEREFORE, OUTSIDE OF THE AREAS WHERE SNOW IS EXPECTED OVER THE
ROCKIES AND HIGH PLAINS, THE REMAINDER OF THE COUNTRY SHOULD
GENERALLY BE DRY GOING THROUGH THE HOLIDAY WEEKEND.
