...PACIFIC STORM SYSTEM TO BRING BENEFICIAL RAIN AND HIGHER  
ELEVATION SNOW TO THE NORTHWEST...  
 
...VERY WARM AND DRY FALL WEATHER TO SHIFT EAST FROM THE ROCKIES  
INTO THE PLAINS, MISSISSIPPI RIVER VALLEY AND MIDWEST THROUGH  
EARLY THIS WEEK...  
 
A LARGE PACIFIC STORM SYSTEM WILL CONTINUE TO MOVE INTO THE  
NORTHWESTERN U.S. OVER THE NEXT COUPLE OF DAYS, BRINGING COLDER  
TEMPERATURES AND MUCH NEEDED RAIN/MOUNTAIN SNOW TO THE REGION.  
ONGOING LIGHT RAIN ACROSS PORTIONS OF WESTERN WASHINGTON AND  
OREGON WILL INCREASE IN INTENSITY THROUGH SUNDAY MORNING AS A COLD  
FRONT MOVES INLAND. RAIN SHOWERS WILL CONTINUE IN THE WAKE OF THE  
FRONT WITH ONSHORE FLOW AFFECTING NORTHERN CALIFORNIA TO THE  
WASHINGTON CASCADES ON SUNDAY, BUT COLDER AIR WILL ALSO BE  
FILTERING INTO FROM THE WEST. THIS WILL ALLOW FOR A CHANGEOVER TO  
SNOW FOR THE HIGHER ELEVATIONS OF THE OLYMPICS, CASCADES INTO THE  
NORTHERN ROCKIES FROM SUNDAY INTO MONDAY. PRECIPITATION SHOULD BE  
LARGELY BENEFICIAL GIVEN MODEST FORECAST INTENSITIES AND ONGOING  
DROUGHT CONDITIONS IN PLACE FOR MUCH OF THE NORTHWESTERN QUADRANT  
OF THE U.S. THERE WILL ALSO BE GUSTY WINDS FOR PORTIONS OF THE  
INTERIOR WEST AS THE STORM SYSTEM MOVES INLAND ON SUNDAY,  
ESPECIALLY IN THE LEE OF THE NORTHERN ROCKIES IN MONTANA WHERE A  
HIGH WIND WARNING IS IN EFFECT FOR WIND GUSTS UP TO 70 MPH.  
 
ELSEWHERE ACROSS THE LOWER 48, CONDITIONS WILL REMAIN DRY AND  
RATHER WARM FOR LATE OCTOBER FOR MOST AREAS OUTSIDE OF THE  
NORTHEAST AND MID-ATLANTIC. HIGH TEMPERATURES OF 10 TO 20+ DEGREES  
ABOVE AVERAGE WILL ENCOMPASS A LARGE PORTION OF THE WEST-CENTRAL  
U.S. ON SUNDAY, STRETCHING FROM THE GREAT BASIN INTO THE HIGH  
PLAINS. THE ANOMALOUS WARMTH WILL SHIFT EASTWARD FOR MONDAY AND  
TUESDAY, REACHING THE MIDWEST TO LOWER MISSISSIPPI RIVER VALLEY.  
ON MONDAY, HIGH TEMPERATURE DEPARTURES FROM AVERAGE ACROSS THE  
CENTRAL PLAINS INTO PORTIONS OF THE UPPER MIDWEST ARE EXPECTED TO  
RUN 20 TO 30 DEGREES ABOVE LATE OCTOBER AVERAGES.  
 
IN TERMS OF PRECIPITATION, WHILE MOST AREAS WILL REMAIN DRY TO THE  
EAST OF THE CONTINENTAL DIVIDE, LIGHT SHOWERS ARE EXPECTED FROM  
THE EASTERN U.P. OF MICHIGAN INTO NORTHERN NEW YORK AND NORTHERN  
NEW ENGLAND AS A COUPLE OF UPPER LEVEL DISTURBANCES PASS OVER THE  
REGION, WITH COLDER AIR ON SUNDAY/SUNDAY NIGHT SUPPORTING WET SNOW  
MIXING IN. FARTHER SOUTH, SCATTERED SHOWERS AND THUNDERSTORMS WILL  
LINGER NEAR A SLOW MOVING COLD FRONT STRETCHING FROM NORTHEASTERN  
TEXAS TO THE SOUTHEAST. WHILE AN ISOLATED INCH OR TWO WILL BE  
POSSIBLE WITHIN A COUPLE OF THUNDERSTORMS OVER THE CAROLINAS  
THROUGH TONIGHT, MOST AREAS WILL RECEIVE FAR LESS OR EVEN NOTHING,  
WITH AN ISOLATED THREAT FOR SHOWERS CONTINUING INTO MONDAY MORNING.
