...ANOTHER ROUND OF SIGNIFICANT COLD TO IMPACT THE PLAINS AND  
MIDWEST EARLY THIS WEEK...  
 
...WINTRY MIX EXPECTED INTO PORTIONS OF CENTRAL TEXAS MONDAY  
NIGHT...  
 
THE BIG STORY OVER THE LOWER 48 THROUGH TUESDAY WILL BE THE COLD  
OVER THE PLAINS INTO THE MIDWEST. WHILE COLD TEMPERATURES MAY ONLY  
BREAK A HANDFUL OF RECORDS, SNOW AND A WINTRY MIX IS EXPECTED FOR  
LOCATIONS DOWN SOUTH WHO DO NOT TYPICALLY SEE WINTRY PRECIPITATION.  
 
A STRONG COLD FRONT WILL MOVE THROUGH THE NORTHERN PLAINS TODAY  
WITH SNOW SHOWERS ACCOMPANYING THE BOUNDARY. WHILE SNOWFALL  
ACCUMULATIONS ARE EXPECTED TO REMAIN LIGHT, LOCALLY HIGHER TOTALS  
CAN BE EXPECTED IN THE UPSLOPE REGIONS OF THE NORTHERN AND CENTRAL  
HIGH PLAINS THROUGH MONDAY AND NEAR THE TRACK OF THE SURFACE LOW  
THROUGH MINNESOTA INTO THE GREAT LAKES REGION.  
 
TEMPERATURES WILL BE NEAR NORMAL TODAY ACROSS THE CENTRAL AND  
NORTHERN PLAINS BUT BY MONDAY, FORECAST HIGHS STAY BELOW ZERO FOR  
MUCH OF THE DAKOTAS INTO MINNESOTA AND SUB-FREEZING HIGHS WILL  
REACH AS FAR SOUTH AS THE NORTHERN TEXAS PANHANDLE INTO NORTHERN  
OKLAHOMA. THESE NUMBERS WILL BE ROUGHLY 15 TO 30 DEGREES BELOW  
MID-JANUARY AVERAGES.  
 
THE ANOMALOUS COLD WILL CONTINUE SOUTH AND EAST FOR TUESDAY AND BY  
THE TIME THE FRONT REACHES THE SOUTHERN PLAINS, A RAIN/SNOW MIX IS  
EXPECTED TO TRANSITION TO FREEZING RAIN/SLEET AND EVENTUALLY SNOW  
AS COLDER AIR FILTERS SOUTHWARD INTO CENTRAL TEXAS. LIGHT  
ACCUMULATIONS WILL ALSO BE POSSIBLE INTO SOUTHERN OKLAHOMA,  
ARKANSAS AND NORTHERN LOUISIANA MONDAY NIGHT INTO TUESDAY.  
 
OUT WEST, WARM AND MOSTLY DRY CONDITIONS WILL STAY IN PLACE UNTIL  
A COLD FRONT REACHES THE WEST COAST EARLY TUESDAY MORNING BRINGING  
A ROUND OF RAIN FROM CENTRAL CALIFORNIA TO OREGON AND WASHINGTON.  
THIS FIRST ROUND OF RAINFALL IS EXPECTED TO BE BENEFICIAL GIVEN  
BELOW AVERAGE PRECIPITATION OVER THE PAST FEW WEEKS FOR THE  
REGION, BUT HEAVIER RAINFALL WILL BE POSSIBLE FOR THE NORTHWEST  
AND CENTRAL/NORTHERN CALIFORNIA BY LATE IN THE WEEK.
