...ATLANTIC COASTAL PLAINS...
AN UPPER-LOW WILL SLOWLY DRIFT EWD ACROSS GA FOR THE REMAINDER OF
THE AFTERNOON. SFC HEATING HAS CAUSED MODEST DESTABILIZATION UNDER
THE LOW WHICH COMBINED WITH STRONG ASCENT IS RESULTING IN SCATTERED
THUNDERSTORM DEVELOPMENT THIS AFTERNOON. ALTHOUGH SHEAR IS WEAK AND
MID-LEVEL LAPSE RATES ARE NOT THAT STEEP NEAR THE UPPER-LOW...COLD
AIR ALOFT EXISTS NEAR THE LOW CENTER WITH 500 MB TEMPS NEAR -18 C. 
THIS COMBINED WITH SBCAPE VALUES ABOVE 1000 J/KG SHOULD BE ENOUGH
FOR A MARGINAL HAIL POTENTIAL WITH THE STRONGER CELLS. AS
INSTABILITY DECREASES THIS EVENING...THE HAIL POTENTIAL SHOULD
DIMINISH.

...ROCKIES...
A SHORTWAVE TROUGH...ROTATING EWD THROUGH A LONG-WAVE TROUGH...IS
CURRENTLY MOVING EWD ACROSS THE CNTRL ROCKIES AS EVIDENT ON WV
IMAGERY. STRONG VERTICAL ASCENT AHEAD OF THE SHORTWAVE TROUGH IS
PROVIDING SUPPORT FOR SCATTERED THUNDERSTORMS DEVELOPMENT IN THE
HIGHER TERRAIN. ALTHOUGH MID-LEVEL LAPSE RATES ARE
STEEP...INSTABILITY IS VERY WEAK AND THIS SHOULD LIMIT THE SEVERE
WEATHER POTENTIAL ACROSS THE REGION.

...NRN CA...
STRONG STORMS HAVE DEVELOPED IN THE SACRAMENTO VALLEY WHERE SFC
WINDS HAVE BECOME LOCALLY BACKED. THE STRONGLY SHEARED ENVIRONMENT
AND INSTABILITY WILL CONTINUE TO CREATE A THREAT FOR ISOLATED SEVERE
STORMS TROUGH THIS EVENING. THE STRONGLY VEERED LOW-LEVEL WINDS AND
STEEP MID-LEVEL LAPSE RATES WILL CREATE A MARGINAL TORNADO AND/OR
HAIL THREAT WITH ROTATING CELLS...REF MCD 527.
