WHAT IS LEFT OF TROPICAL CYCLONE BILL WILL BE ABSORBED INTO THE WESTERLIES AND CROSS OVER OR JUST NORTH OF THE AREA SATURDAY NIGHT. GUIDANCE IS IN GOOD AGREEMENT ON THE TRACK...BUT OVERALL HAS TRENDED A LITTLE SLOWER. THE INCREASE IN MOISTURE WILL LIKELY RESULT IN HEAVY RAIN...ESPECIALLY FOR NORTHERN PARTS OF THE AREA /I.E. NORTHERN MARYLAND AND THE POTOMAC HIGHLANDS/ CLOSER TO BEST LIFT. THE TIMING IS NOT THE MOST FAVORABLE FOR SEVERE WEATHER...BUT GIVEN THE STRONG LOW-LEVEL SHEAR THERE MAY STILL BE AT LEAST A LOW CHANCE OF SEVERE WEATHER AS THE SYSTEM MOVES THROUGH.
