ON THURSDAY, SNOW IS FORECAST FOR THE CENTRAL PLAINS AS AN  
UPPER-LEVEL DISTURBANCE MOVES ACROSS. 2 TO 5 INCHES OF SNOW, WITH  
LOCALLY HIGHER AMOUNTS, IS EXPECTED FOR PARTS OF KANSAS, NEBRASKA,  
AND MISSOURI. UPPER-LEVEL DISTURBANCES WILL COMBINE AND STRENGTHEN  
OVER THE NEXT COUPLE OF DAYS, AND A COUPLE OF SURFACE LOWS WILL  
DEVELOP AND STRENGTHEN TOO--ONE IN THE UPPER GREAT LAKES, AND ONE  
MOVING ALONG THE EASTERN SEABOARD. THIS WILL LEAD TO SNOW  
SPREADING TO THE UPPER MIDWEST AND UPPER GREAT LAKES REGION ON  
THURSDAY NIGHT, WITH MIXED RAIN AND SNOW POSSIBLE IN THE LOWER  
GREAT LAKES REGION BY FRIDAY. HEAVY SNOW OF 6 TO 10 INCHES IS  
FORECAST FOR PARTS OF THE UPPER GREAT LAKES REGION, WITH 4 TO 8  
INCHES DOWNWIND OF THE GREAT LAKES ON FRIDAY AND FRIDAY NIGHT.  
FARTHER SOUTH, THE PRECIPITATION IS EXPECTED TO STAY RAIN IN  
TENNESSEE VALLEY, SOUTHERN APPALACHIANS, MID-ATLANTIC, AND THE  
COASTAL NORTHEAST ON FRIDAY.  
 
VERY COLD TEMPERATURES ARE FORECAST TO CONTINUE IN THE NORTHERN  
AND CENTRAL PLAINS. AS ANOTHER COLD FRONT MOVES THROUGH ON FRIDAY,  
TEMPERATURES 15 TO 30 DEGREES BELOW NORMAL ARE EXPECTED. THIS WILL  
LEAD TO HIGH TEMPERATURES BELOW FREEZING FOR SOUTH DAKOTA AND  
NEBRASKA, WITH HIGHS IN THE TEENS IN NORTH DAKOTA. A NUMBER OF LOW  
MAXIMUM TEMPERATURES COULD BE SET, ESPECIALLY IN THE CENTRAL  
PLAINS.  
 
THE COMBINATION OF ONGOING DROUGHT, HIGH WINDS, AND VERY LOW  
RELATIVE HUMIDITY WILL LEAD TO DANGEROUS CONDITIONS FOR FIRE  
WEATHER IN PARTS OF CALIFORNIA. THE STORM PREDICTION CENTER HAS  
INDICATED THAT EXTREMELY CRITICAL CONDITIONS ARE FORECAST TODAY  
FOR SOUTHERN CALIFORNIA, AS STRONG SANTA ANA WINDS RAMP UP.  
CRITICAL FIRE WEATHER CONDITIONS ARE EXPECTED IN NORTHERN  
CALIFORNIA. WIDESPREAD RED FLAG WARNINGS ARE ALSO IN EFFECT.  
 
AS A SLOW-MOVING FRONT LINGERS NEAR THE GULF COAST, AREAS FROM THE  
SOUTHERN PLAINS TO THE SOUTHEAST WILL CONTINUE TO SEE SCATTERED  
SHOWERS AND THUNDERSTORMS THROUGH FRIDAY. MARGINAL RISKS OF BOTH  
SEVERE WEATHER AND FLASH FLOODING ARE IN PLACE FOR PARTS OF THESE  
AREAS. THE FRONT WILL BEGIN TO MOVE MORE QUICKLY OFFSHORE BY  
FRIDAY EVENING AS A HIGH PRESSURE SYSTEM DROPS SOUTH, LOWERING  
RAIN CHANCES FOR THE WEEKEND AND COOLING DOWN TEMPERATURES FOR THE  
SOUTHERN PLAINS AS WELL.
