A bit of ice before daybreak

**04Z (11 p.m. EST) Update**
NWS-LWX upgraded the counties to our NW to a winter storm warning for ice/snow accumulations - specifically ice/sleet of 0.2"-0.3", enough to give some trouble. Precip has been coming down steadily as a -FZRA -PL mixture for the past two hours; my car has a good coating of ice on it (well, it had - I went out and scraped it off).

We finally get a coastal low moving close enough to us to give us precip, but the atmosphere will be too warm for snow. Instead we're getting a mixture of ZR/IP now, to be followed by a quick changeover to rain early Tue morning. We'll see how quickly the changeover occurs; I'm personally surprised by the intensity of precipitation, as by 01Z the radar was quickly filling in with 20-25 dBZ echoes.
