...HEAVY RAINFALL AND CONCERNS FOR FLASH FLOODING WILL EXIST
THROUGH THURSDAY MORNING ACROSS THE LOWER MISSISSIPPI VALLEY...
...A SWATH OF FREEZING RAIN AND SOME ACCUMULATING SNOWFALL WILL
IMPACT PORTIONS OF THE MIDWEST, LOWER GREAT LAKES, AND THE
NORTHEAST...
...MUCH MILDER AIR WITH TEMPERATURES SURGING WELL ABOVE NORMAL CAN
BE EXPECTED THROUGH THE MIDDLE OF THE WEEK FOR MUCH OF THE EASTERN
HALF OF THE COUNTRY...
A LOW PRESSURE SYSTEM IN THE LOWER MISSISSIPPI VALLEY SUPPORTED BY
AN UPPER TROUGH DIGGING INTO THE SOUTHWEST WILL CONTINUE TO
PRODUCE HEAVY TO EXCESSIVE RAINFALL AND FLASH FLOODING CONCERNS
ACROSS PORTIONS OF THE SOUTHERN PLAINS, GULF COAST, LOWER
MISSISSIPPI VALLEY AND SOUTHEAST THROUGH MIDWEEK. TONIGHT, REPEAT
ROUNDS OF CONVECTION WILL PRODUCE HEAVY RAINFALL ALONG A
STATIONARY FRONT OVER PARTS OF THE ARKLATEX DOWN TO THE
TEXAS/LOUISIANA COAST. A MODERATE RISK OF EXCESSIVE RAINFALL IS IN
EFFECT FOR AREAS INCLUDING EASTERN TEXAS, SOUTHERN ARKANSAS AND
NORTHWESTERN LOUISIANA FOR THIS EVENING. THE FINAL STORM OF THE
EVENING IS FORECAST TO ORGANIZE ON WEDNESDAY MORNING AND GENERATE
ADDITIONAL FLASH FLOODING IMPACTS OVER THE CENTRAL GULF COAST INTO
THE LOWER MISSISSIPPI VALLEY. ANOTHER MODERATE RISK OF EXCESSIVE
RAINFALL IS IN EFFECT OVER PARTS OF CENTRAL LOUISIANA, CENTRAL
MISSISSIPPI AND NORTHWESTERN ALABAMA WHERE THIS ORGANIZED COMPLEX
OF STORMS WILL PRODUCE HIGH RAINFALL RATES AND POTENTIAL TRAINING
WITHIN A RICH MOISTURE ENVIRONMENT. A CONTINUOUS FETCH OF MOISTURE
WILL STREAM INTO THE CENTRAL GULF COAST FROM WEDNESDAY NIGHT
THROUGH THURSDAY NIGHT, LEADING TO MORE FLASH FLOODING CONCERNS
FROM LOUISIANA TO SOUTHWEST VIRGINIA/SOUTHEAST KENTUCKY WHERE A
BROAD SLIGHT RISK OF EXCESSIVE RAINFALL IS IN EFFECT.
TO THE NORTH OF THIS SYSTEM WEAK HIGH PRESSURE WILL FILTER IN A
SHALLOW LAYER OF COOL AIR WHICH WILL PROMOTE SOME LIGHT FREEZING
RAIN OVER PARTS OF THE MIDWEST TONIGHT.
