TWO WEAK BUT PERSISTENT UPPER LOWS CONTINUE TO AFFECT THE CONUS

SHOWERS AND THUNDERSTORMS FROM PARTS OF KS/OK INTO THE UPPER OH
VALLEY AND MID ATLANTIC STATES. NO SEVERE WEATHER IS ANTICIPATED
ALONG THIS CORRIDOR.

A SECOND UPPER LOW IS OVER CA. WATER VAPOR IMAGERY SHOWS A SERIES
OF MINOR SHORTWAVE TROUGHS ROTATING AROUND THE LOW...WHICH WILL
AFFECT THE SOUTHWEST STATES THIS AFTERNOON AND TONIGHT. AN AXIS OF
SCATTERED THUNDERSTORMS HAS BEEN OCCURRING THIS MORNING ROUGHLY FROM
SBA TO LAS. ALONG AND SOUTH OF THESE STORMS...STRONG HEATING AND
COOL TEMPERATURES ALOFT WILL YIELD RELATIVELY STEEP LAPSE RATES AND
MODERATE INSTABILITY. WEAK ASCENT AHEAD OF THE APPROACHING SYSTEMS
MAY RESULT IN SCATTERED THUNDERSTORMS OVER THE MOUNTAINS AND DESERTS
OF SOUTHERN CA AND SOUTHERN AZ LATER TODAY. VERTICAL SHEAR IS
MARGINAL...BUT ORGANIZED MULTICELL STRUCTURES ARE POSSIBLE WITH HAIL
AND GUSTY WINDS IN THE STRONGEST STORMS.
