(EXTRACTED FROM FXUS61 KPHI 192335) The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG, KILG, KMIV, KACY and surrounding areas. Tonight...Ceilings quickly lower to MVFR and IFR as precipitation overspreads the region from southwest to northeast. All rain expected at MIV and ACY; a snow/rain mix may occur at ILG, PHL/PNE to TTN at the onset then all rain; RDG and ABE start as snow then quickly go over to sleet and freezing rain then rain overnight. Main snow and ice accumulations occur at RDG and ABE. Low confidence on the timing of the precipitation type changes. Easterly winds around 10 knots, turning southeast or south toward morning (some gusts to 20-25 knots possible overnight mainly at ACY). A low-level southerly jet around 2000 feet overnight into early Sunday of 40-50 knots results in low-level wind shear. Sunday...MVFR/IFR conditions to start, then rapidly improving by late morning or afternoon as the precipitation ends. An abrupt wind shift to the northwest occurs by midday with winds increasing to 15- 25 knots with gusts to around 35 knots (highest during the afternoon/evening). Low confidence on timing for improvement to VFR. Outlook... Sunday night and Monday...VFR. Northwest winds 15-20 knots with gusts to around 30 knots, diminishing Monday night. Tuesday...VFR. Northwest winds 10-20 knots, diminishing by late afternoon. Wednesday and Thursday...Sub-VFR conditions possible with the chance for some snow to a rain/snow mix.
