DISCUSSION
ONSHORE FLOW WILL PERSIST AS HIGH PRESSURE REMAINS ANCHORED OVER THE
WESTERN ATLANTIC. A TIGHTENING PRESSURE GRADIENT BETWEEN THIS HIGH
AND LOW PRESSURE ACROSS THE PLAINS STATES WILL LEAD TO STRENGTHENING
WINDS, ESPECIALLY WEST OF THE MISSISSIPPI RIVER. EXERCISE CAUTION
HEADLINES WILL REMAIN IN EFFECT THROUGH TONIGHT. AS MOISTURE
INCREASES ACROSS THE REGION, HE CHANCE OF DAILY SHOWERS AND STORMS
WILL GRADUALLY INCREASE, WITH THE BEST CHANCES LATER IN THE WEEK AS
A WEAK FRONT APPROACHES THE AREA. SOME STORMS WILL BE CAPABLE OF
PRODUCING LOCALLY HAZARDOUS WINDS AND WAVES.
