..GREAT PLAINS WARM UP THIS WEEKEND
...SEVERAL ROUNDS OF MODERATE TO LOCALLY HEAVY PRECIPITATION TO
CONTINUE INTO PORTIONS OF THE PACIFIC NORTHWEST, NORTHERN ROCKIES
AND NORTHERN CALIFORNIA THIS WEEKEND INTO EARLY NEXT WEEK...
WAVES OF LOW PRESSURE WILL CONTINUE BRINGING MODERATE TO HEAVY
RAINFALL AND MOUNTAIN SNOW TO THE NORTHWEST CONUS THIS WEEKEND
INTO EARLY NEXT WEEK. LOCALLY HEAVY RAINFALL MAY CAUSE ISOLATED
INSTANCES OF FLASH FLOODING ALONG THE COASTAL RANGES OF THE
PACIFIC NORTHWEST THIS WEEKEND. THUS, THERE'S A MARGINAL RISK OF
EXCESSIVE RAINFALL LEADING TO FLASH FLOODING EXTENDING FROM
COASTAL WASHINGTON DOWN TO THE NORTHERN CALIFORNIA COAST THROUGH
SUNDAY. BETWEEN 2-4 INCHES OF RAINFALL ARE EXPECTED WITH LOCALLY
HIGHER AMOUNTS, ESPECIALLY OVER TERRAIN THROUGH THE END OF THE
WEEKEND.
ELSEWHERE, SHORTWAVE ENERGY MOVING THROUGH THE MISSISSIPPI VALLEY
WILL GENERATE LIGHT RAIN/SNOW SHOWERS FROM THE NORTHERN PLAINS,
ACROSS THE GREAT LAKES AND INTO THE INTERIOR NORTHEAST THIS
WEEKEND. BENEATH THE UPPER TROUGHING OVER THE NORTHERN TIER WILL
RESIDE HIGH PRESSURE AND SOUTHERLY FLOW INTO THE GREAT PLAINS.
WITH THIS COMES WARMER TEMPERATURES FOR MUCH OF THE CENTRAL U.S..
HIGH TEMPERATURES IN THE UPPER 60S TO LOW 80S WILL BE 15-25
DEGREES ABOVE AVERAGE FOR THE CENTRAL/SOUTHERN HIGH PLAINS. THE
ARRIVAL OF ONE SHORTWAVE ON THE HEELS OF ANOTHER WILL SUPPORT A
QUICK REBOUND IN TEMPERATURES FOR THE SOUTHEAST THIS WEEKEND.
