...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS OVER PARTS OF
SOUTH DAKOTA AND NEBRASKA...
..SUMMARY
WIDELY SCATTERED SEVERE STORMS CAPABLE OF MAINLY DAMAGING WIND GUSTS
APPEAR POSSIBLE OVER SOUTH-CENTRAL SOUTH DAKOTA INTO CENTRAL
NEBRASKA THURSDAY AFTERNOON AND EVENING. MORE SPORADIC OCCURRENCES
OF MAINLY DAMAGING WIND APPEAR POSSIBLE FROM THE NORTHERN HIGH
PLAINS INTO THE UPPER MISSISSIPPI VALLEY INTO THE CENTRAL PLAINS,
THE RATON MESA VICINITY, AND THE CENTRAL AND EASTERN GULF COAST.
..CENTRAL TO NORTHERN PLAINS
A MIDLEVEL WAVE IS FORECAST TO MOVE ACROSS THE NORTHERN PLAINS
THURSDAY MORNING, WITH AREAS OF THUNDERSTORMS LIKELY ONGOING FROM
THE DAKOTAS INTO EASTERN NE AND KS. AIDING THIS ACTIVITY WILL BE
THETA-E ADVECTION OUT OF THE SOUTH, WITH THE 850 MB GRADIENT ALIGNED
ROUGHLY ALONG THE MO RIVER. WHILE SOME OF THE REGION WILL BE LOCALLY
STABILIZED BY THIS ACTIVITY, A CORRIDOR OF STRONG HEATING/RECOVERY
WILL OCCUR NEAR THE SURFACE TROUGH DURING THE AFTERNOON, WITH
RENEWED ACTIVITY OVER CENTRAL SD INTO NE. SUBSTANTIAL STORM COVERAGE
WILL LIKELY LEAD TO MERGERS AND AN EVENTUAL MCS MOVING SOUTHEASTWARD
INTO THE EVENING. SPORADIC HAIL MAY OCCUR WITH THE AFTERNOON/INITIAL
CELLS BEFORE TRANSITIONING TO MAINLY A DAMAGING WIND THREAT.
..SOUTHERN AL/GA INTO NORTHERN FL
A SURFACE TROUGH WILL REMAIN DRAPED ACROSS SOUTHERN GA AND AL WITH
MID 70S F DEWPOINTS TO THE SOUTH. A WEAK NORTHWEST FLOW REGIME WILL
ALSO REMAIN OVER THE AREA AS THE UPPER TROUGH OVER THE NORTHEAST
SLOWLY DEPARTS. STRONG DAYTIME HEATING WILL LEAD TO SUBSTANTIAL
INSTABILITY, WITH SCATTERED STORMS DEVELOPING ALONG THE BOUNDARY.
GIVEN THE HIGH PWAT AND STEEP LOW-LEVEL LAPSE RATES, SOME OF THE
CELLS ARE EXPECTED TO PRODUCE LOCALLY DAMAGING GUSTS.
