INTO NORTHERN CALIFORNIA OVER THE NEXT FEW DAYS...
...STRONG WINDS FORECAST THROUGH EARLY SUNDAY ACROSS PARTS OF THE
NORTHERN GREAT BASIN AND NORTHERN HIGH PLAINS...
...LOCALLY HEAVY RAIN AND ISOLATED FLASH FLOODING POSSIBLE

MONDAY...
A SERIES OF FRONTAL SYSTEMS IMPACTING THE PACIFIC NORTHWEST
THROUGH THE END OF THE WEEKEND AND INTO THE BEGINNING OF NEXT WEEK
WILL BRING PERIODS OF MODERATE RAINFALL AND HEAVY MOUNTAIN SNOW.
THE FIRST SYSTEM CONTINUES TO RACE EASTWARD ACROSS THE NORTHERN
GREAT BASIN TODAY AND INTO THE NORTHERN PLAINS TONIGHT. HEAVY SNOW
WILL ACCOMPANY THE STRONG PUSH OF PACIFIC MOISTURE, WITH THE
HIGHEST AMOUNTS LOCATED ACROSS THE NORTHERN CASCADES AND NORTHWEST
MONTANA. ADDITIONALLY, STRONG WINDS ARE EXPECTED FROM EASTERN
WASHINGTON TO NORTHERN MONTANA THROUGH EARLY SUNDAY, WITH MAXIMUM
WIND GUSTS UP TO 80 MPH ALONG THE ROCKY MOUNTAIN FRONT. AS A
RESULT, HIGH WIND WARNINGS ARE IN EFFECT THROUGHOUT NORTH-CENTRAL
MONTANA, WITH WIND ADVISORIES STRETCHING INTO WASHINGTON AND
NORTHEAST MONTANA. THESE STRONG WINDS MAY PRODUCE TREE DAMAGE,
ISOLATED POWER OUTAGES, AND DANGEROUS DRIVING CONDITIONS FOR HIGH
PROFILE VEHICLES DUE TO CROSS WINDS. THE NEXT SYSTEM WILL APPROACH
THE REGION ON MONDAY WITH ANOTHER ROUND OF COASTAL RAIN AND
MOUNTAIN SNOW, WITH PRECIPITATION ALSO EXTENDING AS FAR SOUTH AS
NORTHERN CALIFORNIA.
FOR THE CENTRAL AND EASTERN U.S., A STRONG AREA OF HIGH PRESSURE
IS FORECAST TO REMAIN IN PLACE FOR MUCH OF THE REGION AND LEAD TO
MOSTLY DRY CONDITIONS. HEAVY RAIN IS POSSIBLE; HOWEVER, JUST TO
THE NORTH OF A STATIONARY FRONT LINGERING OVER THE GULF OF MEXICO.
WIDESPREAD SHOWERS AND ISOLATED THUNDERSTORMS ARE MOST LIKELY TO
OCCUR OVER SOUTH TEXAS ON SUNDAY BEFORE MIGRATING EASTWARD ALONG
THE GULF COAST TOWARD SOUTHERN LOUISIANA ON MONDAY. MUCH OF THIS
REGION COULD USE THE RAINFALL AS DROUGHT CONDITIONS EXIST, BUT
URBAN LOCATIONS COULD STILL EXPERIENCE ISOLATED FLASH FLOODING
WHERE INTENSE RAINFALL RATES OCCUR. SOUTH TEXAS IS AN AREA THAT
HAS EXPERIENCED HEAVY RAINFALL RECENTLY, WHICH COULD LEAD TO MORE
SCATTERED FLASH FLOOD CONCERNS ON SUNDAY.
PRECIPITATION CHANCES ALSO EXIST THROUGH TONIGHT ACROSS THE
SOUTHEAST AS LIGHT RAIN EVENTUALLY EXITS BY SUNDAY AFTERNOON.
THERE IS ALSO RAIN AND SNOW SHOWER CHANCES FROM NORTHERN WISCONSIN
TO THE U.P. OF MICHIGAN OVERNIGHT TONIGHT NORTH OF A WARM FRONT.
BELOW AVERAGE TEMPERATURES OVER THE NEXT FEW DAYS ARE FORECAST TO
BE CONFINED TO THE EAST COAST (UNDERNEATH HIGH PRESSURE) AND TEXAS
(AMPLE CLOUD COVER). THE REST OF THE NATION CAN EXPECTED ABOVE
AVERAGE HIGH TEMPERATURES ON SUNDAY AND MONDAY THAT TOP OUT IN THE
50S AND 60S, EXCEPT WHERE 70S AND 80S REMAIN IN THE SOUTHWEST.
