...WINTRY WEATHER EXPECTED FOR THE INTERIOR NEW ENGLAND ON NEW  
YEAR'S DAY...  
 
...HEAVY RAIN AND SNOW TO IMPACT AREAS FROM THE FOUR CORNERS TO  
THE SOUTHEAST OVER THE NEXT FEW DAYS...  
 
THE STRONG SYSTEM THAT BROUGHT RAIN ACROSS THE MID-ATLANTIC AND  
NORTHEAST ON NEW YEAR'S EVE WILL LIFT NORTHWARD INTO THE CANADIAN  
MARITIMES EARLY THIS MORNING. THIS WILL BRING PRECIPITATION ACROSS  
NEW ENGLAND--MOSTLY IN THE FORM OF SNOW. BY LATER IN NEW YEAR'S  
DAY AND INTO EARLY HOURS OF WEDNESDAY, SNOW AND RAIN WILL TAPER  
OFF AND COME TO AN END.  
 
AN UPPER-LEVEL LOW IS FORECAST TO DEVELOP OVER THE FOUR CORNER  
REGION, BRINGING YET ANOTHER ROUND OF SIGNIFICANT SNOWFALL FOR  
PARTS OF ARIZONA, COLORADO, AND NEW MEXICO. TO THE EAST, THE COLD  
FRONT ASSOCIATED WITH THE SYSTEM MOVING ACROSS NEW ENGLAND WILL  
BECOME QUASI-STATIONARY ACROSS THE SOUTHEAST. LIGHT SHOWERS CAN BE  
EXPECTED ALONG THIS BOUNDARY. MEANWHILE, AS THE UPPER-LEVEL LOW IS  
FORECAST TO HEAD EAST TOWARDS THE SOUTHERN PLAINS, A SURFACE LOW  
WILL FORM IN THE GULF OF MEXICO NEAR DEEP SOUTH TEXAS. THIS LOW  
WILL LIFT NORTH TOWARD THE TEXAS COASTLINE ON THROUGHOUT THE DAY  
ON WEDNESDAY--BRINGING MORE PRECIPITATION ALONG THE WESTERN AND  
CENTRAL GULF COAST. LATER ON WEDNESDAY AND INTO THURSDAY, HEAVY  
RAIN WILL SET UP ALONG THE SOUTHERN PLAINS EASTWARD INTO THE  
SOUTHEAST. A WINTRY MIX IS POSSIBLE ALONG THE NORTHERN EDGE OF THE  
PRECIPITATION SHIELD IN PARTS OF THE SOUTHERN PLAINS ON WEDNESDAY  
AND INTO THURSDAY.  
 
A SYSTEM IN THE PACIFIC WILL APPROACH THE PACIFIC NORTHWEST BY  
LATE WEDNESDAY AND INTO THURSDAY. THIS WILL INCREASE PRECIPITATION  
ACROSS THE REGION--WITH RAIN IN THE LOWER ELEVATIONS AND SNOW  
ACROSS THE WASHINGTON CASCADES AND NORTHERN PORTIONS OF THE  
NORTHERN ROCKIES. IN TERMS OF TEMPERATURES, NEW YEAR'S DAY WILL BE  
QUITE COLD FOR THE PLAINS, NEARING 30 DEGREES BELOW NORMAL, WHILE  
THE EAST COAST WILL BE VERY WARM--WITH TEMPERATURES REACHING 20-25  
DEGREES ABOVE NORMAL. BY THURSDAY, THE SOUTHERN PLAINS AND FOUR  
CORNERS WILL REMAIN COOLER THAN NORMAL WHILE THE NORTHERN PLAINS  
AND UPPER MIDWEST WILL EXPERIENCE HIGH TEMPERATURES ALMOST 20  
DEGREES ABOVE NORMAL.
