VALID 12Z THU FEB 21 2019 - 12Z SAT FEB 23 2019  
 
...HEAVY RAIN CONTINUES ACROSS THE SOUTHEAST THROUGH FRIDAY AND  
HEAVY SNOW EXPECTED FOR THE SOUTHERN ROCKIES...  
 
WET WEATHER IS FORECAST TO CONTINUE THROUGH THE END OF THE WEEK  
ACROSS MUCH OF THE GULF COAST REGION AND THE SOUTHEAST U.S. GIVEN  
THE PRESENCE OF A STATIONARY FRONT THAT REMAINS ANCHORED IN PLACE.  
MULTIPLE ROUNDS OF SHOWERS AND THUNDERSTORMS ARE EXPECTED TO  
PROGRESS FROM SOUTHWEST TO NORTHEAST AND RESULT IN 2 TO LOCALLY 4  
INCHES OF RAIN IN A CORRIDOR FROM LOUISIANA TO KENTUCKY, AND FLOOD  
WATCHES REMAIN IN EFFECT FOR MANY OF THESE AREAS. THE OVERALL  
WEATHER PATTERN IS QUITE SIMILAR TO THE PAST COUPLE OF DAYS EXCEPT  
THAT TEMPERATURES ARE A LITTLE WARMER WITH MUCH LESS EXPECTED IN  
TERMS OF ANY WINTRY WEATHER ON THE NORTH SIDE OF THE  
PRECIPITATION. ONGOING RIVER FLOODING WILL ALSO CONTINUE TO BE  
PROBLEMATIC. AREAS OF DENSE FOG OVER PARTS OF THE DEEP SOUTH ARE  
EXPECTED THURSDAY MORNING AS HIGHER HUMIDITY ADVECTS NORTHWARD  
FROM THE GULF OF MEXICO.  
 
TEMPERATURES WILL CONTINUE TO BE BELOW AVERAGE ACROSS MUCH OF THE  
WESTERN U.S. AND ACROSS THE NORTHERN PLAINS AS A BROAD UPPER LEVEL  
TROUGH CONTINUES TO GOVERN THE WEATHER PATTERN. A STRONG UPPER  
LEVEL SYSTEM IS FORECAST TO SLOWLY CHURN ACROSS THE SOUTHWEST ON  
THURSDAY AND THEN EXIT ACROSS THE SOUTHERN PLAINS BY FRIDAY  
EVENING. THIS WILL BRING VERY HEAVY SNOW TO THE HIGHER ELEVATIONS  
OF THE SOUTHWEST AND SOUTHERN ROCKIES, WITH THE MOGOLLON RIM OF  
ARIZONA AND THE SAN JUAN MOUNTAINS OF COLORADO GETTING HAMMERED  
WITH 1 TO 3 FEET OF SNOW! ADDITIONAL SNOWFALL IS EXPECTED FROM  
EASTERN COLORADO TO MINNESOTA ALONG A DEVELOPING FRONT, BUT THESE  
AMOUNTS ARE EXPECTED TO BE LIGHT TO MODERATE COMPARED TO THE EVENT  
OVER THE SOUTHERN ROCKIES.
