NO SGFNT CHGS FOR THE ERLY MRNG UPDT. PREVIOUS DISC...A WEAK COLD FRONT WILL SLOWLY CROSS THE AREA TODAY. LITTLE UPPER LEVEL SUPPORT WILL PREVENT MUCH PRECIPITATION AS THE FRONT WILL BE RUNNING INTO AN EASTERN RIDGE. ATMOSPHERE REMAINS RATHER STABLE THROUGH MUCH OF THE MORNING...BUT WILL DESTABILIZE AS AFTERNOON APPROACHES. THIS WILL BE IN RESPONSE TO THE HIGHER SURFACE DEW POINTS WHICH WILL NOSE IN ALONG THE BOUNDARY LATER THIS MORNING. WITH THIS INCREASE IN BUOYANCY...LOOKS LIKE THE BEST PLACE FOR ACTIVITY WOULD BE ACROSS THE THE FAR SOUTH THIS AFTERNOON. WITH DAYTIME HEATING...CONVECTION MAY QUICKLY DEVELOP ALONG A LINE OF LOW LEVEL FORCING AND MOISTURE CONVERGENCE ON EITHER SIDE OF THE MASON-DIXON LINE. EXPECT A RANGE OF TEMPS TODAY FROM NORTH TO SOUTH.
