VALLEY AND BRING A COLD FRONT THROUGH THE REGION TONIGHT.
AHEAD OF THE COLD FRONT ABUNDANT MOISTURE AND STRONG WINDS WILL BE
IN PLACE. WITH MARGINAL INSTABILITY IN PLACE...A STRONG
DISTURBANCE MOVING THROUGH THE CENTRAL PLAINS SHOULD HELP DEVELOP
THUNDERSTORMS DURING THE DAY WITH A FEW BECOMING STRONG TO SEVERE.
WITH THE AMOUNT OF SHEAR EXPECTED ANY DEEP THUNDERSTORM WILL HAVE
THE CAPABILITY OF PRODUCING BOWING STRUCTURES OR SUPER CELLS. THIS
WILL BRING A RISK OF DAMAGING WINDS AND ISOLATED TORNADOES...A FEW
OF WHICH COULD BE STRONG...EF2 OR HIGHER.
THE SEVERE RISK WILL END TONIGHT AFTER THE PASSAGE OF THE COLD
FRONT.
...MARINE HAZARDS...
SMALL CRAFT ADVISORIES ARE IN EFFECT TODAY AND TONIGHT ACROSS THE

COLD FRONT ON WEDNESDAY...AND A SMALL CRAFT ADVISORY MAY BE
REQUIRED FOR A PORTION OF THE COASTAL WATERS WEDNESDAY MORNING.
STRONG WINDS AND HIGH SEAS WILL DEVELOP AGAIN WEDNESDAY NIGHT AND
PERSIST THROUGH EARLY SATURDAY MORNING.
...THUNDERSTORMS...
