Winter weather adivsory for freezing rain tonight…

February 21st, 2013 at 9:41 am by under Weather

We are starting off cloudy and with a few flurries, but most of the day will be dry, as we top out in the uppper 20s.  A Winter Weather Advisory goes into effect for all of the Miami Valley at 8pm, as wintry precipitation will spread in during the late evening.  It looks like it will really get going around 10 or 11pm.  Initially, we could see some sleet, but the main precipitation type looks to be freezing rain through the overnight hours:

Freezing rain will continue into early Friday morning.  What is happening: warmer air is building in aloft… so precip will fall as liquid.  THEN these liquid droplets reach our sub-freezing temperatures at the surface, and will freeze on contact with objects.  Ice accumulation is likely through Friday morning… here’s just one model’s forecast on how much to expect:

This would mean a sheet of ice on most objects outdoors… and untreated surfaces including roads, sidewalks and driveways will be extremely slippery.  If you do have to travel during this timeframe, it will be quite difficult… here’s a look at road conditions… green = good…. red = poor:

By mid-late morning Friday, we’ll have surface temperatures gradually coming up above freezing.  This will help change freezing rain over to just rain.  So expect improving conditions… but we still will likely have school delays or even closings.  You can keep tabs on the list here: WDTN SCHOOL CLOSINGS/DELAYS

Friday afternoon, we’ll even climb into the mid-40s… so we start to see melting, even.  Right now the weekend looks nice, with near-normal temperatures.  We’ll keep you posted on the storm so stay tuned!!
