...MOUNTAIN SNOW CONTINUES OVER PARTS OF THE CENTRAL AND NORTHERN  
ROCKIES THROUGH WEDNESDAY...  
   
..RECORD WARMTH EXPANDS INTO THE EASTERN U.S. THROUGH THURSDAY  
  
...SEVERE THUNDERSTORMS ARE LIKELY ACROSS PORTIONS OF THE CENTRAL  
AND SOUTHERN PLAINS AS WELL AS THE MIDDLE AND LOWER MISSISSIPPI  
VALLEY ON WEDNESDAY...  
  
A POTENT STORM SYSTEM LOCATED OVER THE CENTRAL AND NORTHERN  
ROCKIES WILL CONTINUE TO PRODUCE MODERATE TO HEAVY SNOW ACROSS THE  
HIGH ELEVATIONS OF UTAH, WYOMING, AND COLORADO TONIGHT INTO  
WEDNESDAY. AN INJECTION OF COLDER AIR COMBINED WITH A TAP OF  
SIGNIFICANT MOISTURE WILL RESULT IN SNOW ACCUMULATIONS UP TO A  
FOOT FOR MANY MOUNTAIN RANGES IN THE REGION. THE SNOW WILL MAKE  
FOR DIFFICULT TRAVEL OVER THE HIGH MOUNTAIN PASSES, ESPECIALLY  
DURING THE NIGHTTIME AND EARLY MORNING HOURS TONIGHT INTO  
WEDNESDAY. NUMEROUS WINTER STORM WARNINGS AND WINTER WEATHER  
ADVISORIES REMAIN IN EFFECT. BE PREPARED FOR WINTER DRIVING  
CONDITIONS AND SLOWER TRAVEL SHOULD YOU NEED TO VENTURE OUT INTO  
THE HIGH COUNTRY. IN THE WAKE OF THE STORM, MUCH COLDER AIR WILL  
LEAD TO FROST AND FREEZE CONCERNS FOR THE LOWER ELEVATIONS TONIGHT  
AND AGAIN ON WEDNESDAY NIGHT, LIKELY MARKING AN END TO THE GROWING  
SEASON FOR MANY LOCATIONS.  
  
OUT AHEAD OF THE STORM AND COLD FRONT THAT IS BRINGING SNOW TO  
PARTS OF THE CENTRAL AND NORTHERN ROCKIES IS A SURGE OF  
UNSEASONABLE WARMTH THAT IS GRADUALLY EXPANDING EASTWARD FROM THE  
CENTRAL U.S. TO THE EASTERN U.S. THROUGH THURSDAY. HIGH  
TEMPERATURES WILL SOAR INTO THE 70S AND 80S ACROSS A LARGE PORTION  
OF THE EASTERN HALF OF THE COUNTRY THE NEXT COUPLE OF DAYS, WITH  
HIGHS ECLIPSING THE 90 DEGREE MARK ACROSS PARTS OF THE SOUTHERN  
PLAINS, LOWER MISSISSIPPI VALLEY, AND SOUTHEAST. TEMPERATURES WILL  
REMAIN QUITE MILD AT NIGHT AS WELL, WITH OVERNIGHT LOWS DROPPING  
ONLY INTO THE 50S AND 60S. COMPARED TO CLIMATOLOGY, TEMPERATURES  
THAT WARM THIS LATE IN THE YEAR ARE EASILY 25 TO 35 DEGREES ABOVE  
NORMAL... AND ARE LIKELY TO SET MANY DAILY HIGH AND HIGH MINIMUM  
TEMPERATURE RECORDS THROUGH THURSDAY. IN FACT, MANY PLACES ACROSS  
THE NORTHEAST AND MID-ATLANTIC ARE LIKELY TO EXPERIENCE THEIR  
WARMEST HALLOWEEN ON RECORD, MAKING FOR RATHER PLEASANT CONDITIONS  
FOR TRICK-OR-TREATING THURSDAY EVENING.  
  
THE PERIOD OF RECORD WARMTH WILL COME TO AN END ACROSS MUCH OF THE  
CENTRAL U.S. BY WEDNESDAY NIGHT INTO THURSDAY AS A PASSING COLD  
FRONT IS FORECAST TO BRING MUCH COOLER TEMPERATURES INTO THE  
REGION. BEFORE THAT COMES TO FRUITION, THE COLD FRONT WILL BE  
RESPONSIBLE FOR SPARKING WIDESPREAD SHOWERS AND THUNDERSTORMS  
ACROSS A LARGE PORTION OF THE NATION'S MIDSECTION WEDNESDAY  
AFTERNOON, EVENING, AND NIGHT. SOME OF THE STORMS THAT DEVELOP  
WILL HAVE THE POTENTIAL TO BECOME SEVERE, WITH DAMAGING WINDS,  
LARGE HAIL, AND A FEW TORNADOES POSSIBLE. AS A RESULT, THE STORM  
PREDICTION CENTER HAS ISSUED AN ENHANCED RISK OF SEVERE  
THUNDERSTORMS (LEVEL 3 OF 5) FOR SOUTHEAST NEBRASKA, NORTHWEST  
MISSOURI, MUCH OF EASTERN KANSAS, AND PARTS OF NORTHEAST OKLAHOMA.  
OUTSIDE THE ENHANCED RISK LIES A SLIGHT RISK OF SEVERE  
THUNDERSTORMS (LEVEL 2 OF 5) WHICH EXTENDS FROM SOUTHWEST IOWA  
PARTS OF NORTHERN TEXAS. IN ADDITION TO THE SEVERE THREAT, A FEW  
STRONGER STORMS COULD PRODUCE HEAVY RAINFALL. DESPITE RECENT  
DRYNESS, ISOLATED INSTANCES OF FLASH FLOODING CANNOT BE COMPLETELY  
RULED OUT... AND THE ANOMALOUS MOISTURE IN PLAY WAS ENOUGH FOR THE  
WEATHER PREDICTION CENTER TO ISSUE A MARGINAL RISK (LEVEL 1 OF 4)  
OF EXCESSIVE RAINFALL FROM CENTRAL WISCONSIN SOUTH TO NORTHEASTERN  
TEXAS.
