...HEAVY RAIN AND POTENTIAL FLASH FLOODING POSSIBLE FOR SOUTHEAST  
TEXAS AND INTO PORTIONS OF THE SOUTHEAST...  
 
...SNOW AND ICE TO IMPACT AREAS FROM NEW MEXICO EASTWARD INTO  
OKLAHOMA...  
 
A MID-LEVEL LOW WILL MOVE ACROSS THE SOUTHWEST AND INTO THE  
SOUTHERN PLAINS LATE WEDNESDAY NIGHT AND INTO EARLY THURSDAY  
MORNING. THIS WILL BRING ADDITIONAL SNOWFALL TOTALS ACROSS HIGHER  
ELEVATIONS ACROSS NEW MEXICO TODAY--PARTICULARLY WHERE THERE ARE  
WINTER WEATHER ADVISORIES AND WINTER STORM WARNINGS IN EFFECT. AS  
THIS LOW MOVES FARTHER EAST, A QUASI-STATIONARY BOUNDARY WILL  
CONTINUE TO MEANDER ALONG THE CENTRAL AND WESTERN GULF COAST  
THROUGH THURSDAY. THIS WILL BRING SHOWERS AND THUNDERSTORMS ACROSS  
SOUTHEAST AND SOUTH-CENTRAL TEXAS IN ADDITION TO PORTIONS OF THE  
LOWER MISSISSIPPI VALLEY TODAY. BY THURSDAY, A SURFACE LOW WILL  
LIFT NORTHWARD INTO THE SOUTHEAST, BRINGING ADDITIONAL RAINFALL TO  
PARTS OF THE WESTERN GULF COAST, LOWER MISSISSIPPI VALLEY  
NORTHWARD INTO THE TENNESSEE VALLEY. BY FRIDAY MORNING, EXPECT  
PRECIPITATION TO SHIFT EASTWARD ACROSS MOST OF THE SOUTHEAST AS  
THE SYSTEM PROGRESSES TO THE NORTH AND EAST. THERE IS A SLIGHT  
CHANCE OF FLASH FLOODING FROM SOUTHEAST TEXAS INTO CENTRAL  
MISSISSIPPI FOR TODAY, SHIFTING TO MOST OF LOUISIANA EASTWARD INTO  
CENTRAL GEORGIA ON THURSDAY.  
 
IN ADDITION TO THE FLASH FLOODING CONCERNS, THIS SYSTEM WILL ALSO  
BRING HAZARDOUS WEATHER DUE TO WINTRY PRECIPITATION. AS  
PRECIPITATION INCREASES ACROSS TEXAS, THE NORTH END OF THIS  
PRECIPITATION SHIELD WILL PRODUCE SNOW AND FREEZING RAIN. ICE WILL  
BE A PARTICULAR HAZARD FOR CENTRAL TEXAS NORTHWARD INTO OKLAHOMA  
ON WEDNESDAY NIGHT AND INTO THURSDAY. FURTHERMORE, SNOW WILL ALSO  
BE IMPACTING THESE REGIONS--WITH AS MUCH AS 6 INCHES POSSIBLE  
ALONG PORTIONS OF THE RED RIVER VALLEY. THESE CONDITIONS WILL MAKE  
TRAVELING VERY DIFFICULT. PLEASE SEE WWW.WEATHER.GOV FOR MORE  
SPECIFIC INFORMATION ON WATCHES, WARNINGS, AND ADVISORIES FOR THE  
DIFFERENT REGIONS THAT WILL BE IMPACTED BY THIS SYSTEM.  
 
AS A SYSTEM IN THE PACIFIC SLIDES CLOSER TO THE PACIFIC NORTHWEST,  
RAIN AND HIGHER ELEVATION SNOW WILL BEGIN TO INCREASE BY WEDNESDAY  
NIGHT AND INTO THURSDAY. SNOW ACCUMULATIONS WILL IMPACT THE  
WASHINGTON CASCADES, WITH SOME ACCUMULATIONS IN THE OREGON  
CASCADES AND NORTHERN PORTIONS OF THE NORTHERN ROCKIES. IN TERMS  
OF TEMPERATURES, THE SOUTHERN PLAINS AND FOUR CORNERS WILL BE  
BELOW NORMAL FOR TODAY AND THURSDAY--WITH HIGH TEMPERATURES BEING  
NEARLY 25 DEGREES BELOW NORMAL. THE NORTHERN PLAINS AND UPPER  
MIDWEST WILL BE WARM ON BOTH THURSDAY AND FRIDAY--WITH  
TEMPERATURES REACHING 20 DEGREES ABOVE NORMAL.
