On Sunday...expect another repeat of recent days with afternoon convection developing over higher elevations with little movement into the terminals...so will not mention in TAFs at this time. Winds should remain below 10 KTs throughout the TAF period. && .MRX WATCHES/WARNINGS/ADVISORIES... NC...None. TN...None. VA...None. && mjb
