ACROSS EXTREME SOUTHWEST PORTIONS OF THE CWA. MAIN CONCERN
TODAY WILL BE THE WINDS ALONG THE COAST AS THE PRESSURE GRADIENT
WILL INCREASE IN THE WAKE OF THE COLD FRONT MOVING OFFSHORE

AS A RESULT FOR THIS MORNING INTO THE EVENING AS WINDS GRADUALLY
DIMINISH TONIGHT AS THE CENTER OF THE SURFACE HIGH MOVES INTO THE
SOUTHERN PLAINS. RAIN CHANCES ACROSS THE COASTAL SECTIONS THIS

CLOUDS FRI NIGHT WITH OVERRUNNING CONDITIONS DEVELOPING ACROSS THE
EXTREME SOUTHWEST PORTIONS OF THE CWA. WILL KEEP SLIGHT CHANCE OF
RAIN MAINLY AFTER MIDNIGHT FRIDAY WITH A CHANCE OF RAIN SATURDAY

ACROSS THE SOUTHWEST U.S. MONDAY AND MOVING ACROSS THE SOUTHERN
