Expect low temperatures by morning in the 30's outside of the city and away from the Shore, with low 30's possible in Allentown and Reading, along with some pockets of near freezing air near Millville and Vineland. The balance of the suburbs should drop into the middle 30's and have some patchy frost north of the PA Turnpike and west of the Blue Route...throw a blanket or some towels on the garden as a precaution tonight. The city will safely avoid a frost as lows will drop "only" into the lower 40's.
Tomorrow offers a slightly milder day around the region -- skies will start sunny but some warm air clouds will try to nudge in through the course of the day. It will be a few degrees milder than today as highs should get into the mid 60's in the city -- generally between 62 and 65 in most places. Winds will be a bit lighter than past days -- generally from the west at 6 to 12 mph.
80's loom around here by Thursday as warmer air pushes in, perhaps accompanied by some thunder on Wednesday as a warm front pushes on northeast through the Mid Atlantic.
