RAINFALL AMOUNTS EXPECTED TODAY OVER THE APPALACHIANS, WEST
VIRGINIA IN PARTICULAR, HAS INCREASED. THE CURRENT PRECIPITATION

FOR THE WEST, THUNDERSTORMS WILL BE POSSIBLE ON TUESDAY AND

MOVING INTO THE COLORADO VALLEY AND PROVIDING LARGE SCALE ASCENT.
THERE WILL ALSO BE SUFFICIENT SURFACE INSTABILITY FOR SCATTERED
THUNDERSTORM POTENTIAL. THE WEATHER PREDICTION CENTER HAS A
MARGINAL RISK FOR EXCESSIVE RAINFALL ON WEDNESDAY ACROSS THE
SACRAMENTO VALLEY AND SIERRA NEVADA.
