.DISCUSSION...SURFACE HIGH PRESSURE OVER THE GULF OF MEXICO WILL SHIFT
EASTWARD TO OFF THE EAST US COAST TONIGHT AND FRIDAY. THIS WILL CREATE
A STEADY SOUTHERLY FLOW INTO THE AREA THROUGH TONIGHT...WHICH WILL GRADUALLY
MOISTEN THE AIRMASS OVER THE AREA. PATCHY FOG WILL STILL
BE POSSIBLE...MAINLY EAST OF INTERSTATE 65. MOISTURE
LEVELS ARE NOT EXPECTED TO FALL BELOW CRITICAL LEVELS THE NEXT SEVERAL
DAYS. A DEEP MIXING LAYER WILL CREATE VERY HIGH DAYTIME DISPERSIONS. A
FRONT WILL SLOWLY APPROACH THE AREA FROM THE NORTHWEST THROUGH THE
WEEKEND INTO THE COMING WEEK...STRENGTHENING THE LOW LEVEL FLOW.
