WINTER WEATHER MESS COMING

I muse that when you look at accumulations, this system is small.  Yet, at the same time is as complex a system as I've seen, and precipitation-types will be switching out much of the time, limiting accumulations.  Best way I can put it is, starting just before daybreak Friday through mid day Saturday, there may be periods of slick driving.

A Winter Weather Advisory is in effect for Haywood County from 6am Friday through 12 noon Saturday, and only for elevations above 3,500 feet (the 'blue roof' house).  What accumulations will occur are 1-3" in the advisory, but what works in our favor is that rain mixes in at times, along with afternoon temperatures above 32 degrees.  What starts to accumulate will start to wash away...and so that cycle will continue.

TIMING:  A wintry mix is expected before sunrise Friday.  Snow, sleet, freezing rain, just rain, all is expected to mix in.  But by noon if not earlier, it all turns to a cold rain.  Keep in mind we are heading into this with ground and road temps that are relatively warm, which helps travel.  By Saturday AM before sunrise, rain is expected to kick back over to snow, so I'm guessing if we collect an inch or two it would occur Saturday morning.  There will be more snow chances late Sunday night through Monday night, but the jury isn't in on whether there will be school-stopping snow for Monday morning.

The NWS office from GSP have Balsam possibly accumulating 0.08" of ice from freezing rain...THAT'S not a good thing, should it come to pass.  That's awful close by, too.  The liquid equivalent in this system is also pretty good, with 0.75"-1" forecast.

So, a mess that is as clear as mud is arriving shortly. Any travel problems would literally melt away in a matter of a few hours. I'll be up very early and will post a report by 6am (guessing) as I'm subbing at Bethel Elementary Friday and have to get off the mountain early even if there is a school delay.  Stay tuned...
