BALTIMORE (WJZ) — Wednesday turned partly sunny and windy after the rain (and freezing rain) ended fairly early.  Thursday will be brisk and somewhat colder, but temperatures should recover to levels near or slightly above 40 Friday.

Friday night and on Saturday, as a low pressure system begins to move up the coast, the computer models are starting to ‘weigh in’ on what will happen.  It’s a tricky forecast, because when precipitation gets underway between 11 p.m. Fridayw night and 4 a.m. Saturday from south to north, there are modified soundings that indicate the temperature profile will have a subfreezing layer that is very shallow.  That would imply that while it could be warm enough to rain above 1,500 or 2,000 feet — that rain would freeze on contact with untreated surfaces at the onset of precipitation, or before the surface temperatures start to rise and climb above 32 degrees.  And then there are still other models that imply there could be some snow (as well as ice) occurring at the onset late Friday night before a complete changeover to rain occurs Saturday morning.

We’ll see how this goes.  At least the next 36 hours are dry.

Have a good day!
