..COLD FOR THE EASTERN U.S. AND RAIN FOR THE WEST COAST
 
 
THE COLDEST WEATHER OF THE SEASON IS MAKING ITS PRESENCE KNOWN  
ACROSS MUCH OF THE EASTERN U.S. AFTER THE PASSAGE OF AN ARCTIC  
FRONT EARLIER ON FRIDAY. HIGH TEMPERATURES 15 TO 25 DEGREES BELOW  
AVERAGE BY EARLY NOVEMBER STANDARDS ARE MAKING IT FEEL MORE LIKE  
JANUARY, AND NUMEROUS FREEZE WARNINGS ARE IN EFFECT FROM SOUTH  
CAROLINA TO LONG ISLAND, NEW YORK, FOR OVERNIGHT LOWS IN THE 20S  
TO LOW 30S. RECORD LOWS WILL BE POSSIBLE ACROSS PARTS OF THE OHIO  
VALLEY, GREAT LAKES, NORTHERN MID ATLANTIC, AND NORTHEAST  
INCLUDING MANY OF THE MAJOR CITIES IN THE REGION ON SATURDAY  
MORNING AND AGAIN ON SUNDAY MORNING ACROSS THE NORTHEAST.  
 
ACROSS THE WEST, A FRONT APPROACHING THE REGION FROM THE PACIFIC  
WILL BRING A PERIOD OF WIDESPREAD RAIN TO WESTERN WASHINGTON,  
OREGON, AND ALSO NORTHERN CALIFORNIA, AND SNOW FOR THE HIGHEST  
ELEVATIONS. THE SOUTHWESTERN U.S. WILL BE UNDER THE INFLUENCE OF  
A STRONG UPPER LEVEL RIDGE PROVIDING WARM AND DRY WEATHER THROUGH  
THE WEEKEND. SCATTERED SHOWERS ARE POSSIBLE ALONG THE EAST COAST  
OF FLORIDA WITH MOIST EASTERLY FLOW BEHIND THE COLD FRONT. GIVEN  
THE LACK OF INSTABILITY AND DEEP MOISTURE, LITTLE IN THE WAY OF  
THUNDERSTORM ACTIVITY IS EXPECTED NATIONWIDE.
