...HEAVY RAIN AND SEVERE WEATHER PROBABLE ACROSS THE
CENTRAL/SOUTHERN PLAINS THIS WEEKEND...
...MOUNTAIN SNOW WILL SPREAD FROM THE PACIFIC NORTHWEST INTO MUCH
OF THE INTERMOUNTAIN WEST OVER THE NEXT COUPLE OF DAYS...
...MUCH ABOVE AVERAGE TEMPERATURES EXPECTED ACROSS LARGE PORTIONS
OF THE CENTRAL TO EASTERN U.S....
A COLD FRONT WILL BRING GUSTY WINDS AND COOL TEMPERATURES INTO THE
NORTHEAST BY TONIGHT AND INTO THE WEEKEND. WHILE LESS RECORD
TEMPERATURES ARE FORECAST OVER THE NEXT FEW DAYS ACROSS THE
EASTERN TWO-THIRDS OF THE COUNTRY, WIDESPREAD ABOVE AVERAGE
TEMPERATURES ARE EXPECTED ACROSS LARGE PORTIONS OF THE CENTRAL TO
EASTERN U.S. AS A STRONG DOME OF HIGH PRESSURE BUILDS ACROSS THE
EASTERN HALF OF THE COUNTRY. THE AFOREMENTIONED HIGH PRESSURE
SYSTEM WHICH WILL BUILD ACROSS THE NORTHEAST THIS WEEKEND, WILL
CONTINUE THE DRY CONDITIONS DOWN THE EASTERN SEABOARD FOR THE
FIRST FEW DAYS OF NOVEMBER.
ATTENTION WILL THEN FOCUS ACROSS THE CENTRAL AND SOUTHERN PLAINS
AS A RATHER SIGNIFICANT HEAVY RAIN AND SEVERE WEATHER EVENT WILL
EMERGE THIS WEEKEND. AS MOIST AIR FROM THE GULF OF MEXICO RETURNS
AND STREAMS NORTHWARD INTO THE SOUTHERN PLAINS BEHIND THE HIGH
PRESSURE SYSTEM, A DEEPENING UPPER-LEVEL TROUGH WILL MOVE THROUGH
THE WESTERN U.S. THIS TROUGH WILL SPREAD MORE MOUNTAIN SNOW
ACROSS THE INTERMOUNTAIN WEST THIS WEEKEND. SOUTHWESTERLY FLOW
AHEAD OF THE TROUGH WILL THEN INTERACT WITH THE RETURNING GULF
MOISTURE OVER THE SOUTHERN PLAINS AND LIFT THE MOISTURE OVER A
WARM FRONT. IT APPEARS THAT MODERATE TO HEAVY RAIN ASSOCIATED
WITH ORGANIZED THUNDERSTORMS WILL FIRST DEVELOP OVER THE SOUTHERN
HIGH PLAINS TONIGHT. THE THUNDERSTORMS AND HEAVY RAIN WILL THEN
EXPAND NORTHEASTWARD INTO THE CENTRAL PLAINS THROUGH THE WEEKEND.
A FEW INCHES OF HEAVY RAIN WITH LOCALLY HIGHER AMOUNTS IS FORECAST
ACROSS THE SOUTHERN PLAINS, WITH THE HEAVIEST RAINFALL EXPECTED
ACROSS CENTRAL OKLAHOMA. SIMILAR TO MANY AREAS OF THE LOWER 48,
THIS REGION IS EXPERIENCING MODERATE TO EXTREME DROUGHT
CONDITIONS. WHILE THIS ROUND OF HEAVY RAIN WILL HELP ALLEVIATE
THE DROUGHT, THE HIGH RAINFALL RATES WILL ALSO BRING AN INCREASING
THREAT OF FLASH FLOODING. PLEASE STAY ABREAST OF THE LATEST
FORECAST UPDATES ON THIS UPCOMING HEAVY RAIN/SEVERE WEATHER EVENT
ACROSS THE CENTRAL TO SOUTHERN PLAINS.
