..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 THAT EXITED THE EAST COAST 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. SOME RECORD  
LOWS WILL ALSO BE POSSIBLE. LAKE EFFECT SNOW IS EXPECTED ACROSS  
PARTS OF MICHIGAN ON FRIDAY, AND THIS SHOULD ABATE BY THE WEEKEND  
AS THE ARCTIC AIRMASS MODIFIES.  
 
ACROSS THE WEST, A FRONT APPROACHING THE REGION FROM THE PACIFIC  
WILL BRING WIDESPREAD RAIN TO WESTERN WASHINGTON AND 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.
