300 PM EDT APRIL 15 2024
SYNOPSIS: OVERALL, THE WEEK-2 PERIOD LOOKS FAIRLY QUIET WITH MID-LEVEL RIDGING
FORECAST ACROSS THE CONTIGUOUS U.S. (CONUS) EAST OF THE ROCKY MOUNTAINS.
SURFACE HIGH PRESSURE OVER THE EASTERN CONUS FROM WEEK-1 WILL BRING SLIGHT
CHANCES FOR A FROST OR FREEZE TO AREAS THAT MAY DAMAGE SENSITIVE VEGETATION IN
PORTIONS OF THE EAST. THIS AREA OF HIGH PRESSURE IS FORECAST TO PROGRESS
EASTWARD INTO THE WESTERN ATLANTIC WHICH WILL HELP TO BRING RETURN FLOW OFF THE
GULF OF MEXICO INTO THE MISSISSIPPI VALLEY AND THE SURROUNDING AREAS. THIS
INCREASES CHANCES FOR HEAVY PRECIPITATION INTO THESE REGIONS. FOLLOWING THE
INITIAL RETURN FLOW, A TROUGH PROGRESSING EASTWARD OUT OF THE WEST MAY BRING
INCREASED CHANCES FOR HEAVY RAIN AND THUNDERSTORMS INTO THE CENTRAL AND
SOUTHERN PLAINS. IN PARTS OF THE LOWER-MISSISSIPPI FLOODING REMAINS A CONCERN,
PARTICULARLY IF ADDITIONAL RAIN FALLS IN THIS AREA.
HAZARDS
SLIGHT RISK OF MUCH BELOW NORMAL TEMPERATURES FOR PORTIONS OF THE CENTRAL
PLAINS, MISSISSIPPI, TENNESSEE, AND OHIO VALLEYS, GREAT LAKES, AND
MID-ATLANTIC, TUE, APR 23.
SLIGHT RISK OF HEAVY PRECIPITATION ACROSS PORTIONS OF THE CENTRAL AND SOUTHERN
PLAINS, MIDDLE AND LOWER MISSISSIPPI, THE OHIO AND TENNESSEE VALLEYS, WED-MON,
APR 24-29.
POSSIBLE FLOODING ACROSS PORTIONS OF NORTHEASTERN TEXAS, EXTREME SOUTHEASTERN
OKLAHOMA, AND MUCH OF THE LOWER MISSISSIPPI VALLEY.
