DEVELOP IN LEE OF THE CANADIAN ROCKIES AND SWD INTO THE NRN HIGH

UPPER RIDGE. OTHERWISE...A RELATIVELY COOL/DRY CONTINENTAL AIRMASS

WEAK/HIGH-BASED STORMS WILL BE POSSIBLE ACROSS PORTIONS OF THE NRN
ROCKIES INVOF THE LEE TROUGH...A FEW SEA-BREEZE STORMS APPEAR
POSSIBLE ACROSS CENTRAL AND S FL...AND SCATTERED/LOW-TOPPED SHOWERS
AND THUNDERSHOWERS ARE ALSO ANTICIPATED ACROSS PARTS OF THE
NORTHEAST BENEATH THE UPPER LOW. HOWEVER...MINIMAL INSTABILITY IN
ALL LOCALES SHOULD PRECLUDE APPRECIABLE SEVERE THREAT.
