Update

February 21st, 2013 at 4:23 pm by under Chad's WLFI Weather Blog

Temperatures are running 27-30 degrees across the viewing area with snow & sleet approaching.  Leading edge is virga or precipitation that is not reaching the ground.  However, it goes from virga to moderate to heavy snow & perhaps some sleet rapidly with heavier initial band.  Visibility drops from 10 miles to 0.25 mile at the onset.  Be prepared for sudden significant decrease in visibility.

Actual snow/sleet hitting the ground is about 23 miles from Covington & 53 miles from Lafayette & is moving northeast at around 30 miles per hour.

1-3″ of snow & sleet still looks good with 0.10″ of glaze ice & wind gusts up to 38 mph tonight still looks good.  “Fair game after 5p” still looks good for southwest counties with snow/sleet coming into Lafayette closer to 7.  The entire viewing area will be covered in solid snow, sleet & freezing rain by midnight.  I still would not rule out a rumble or two of thunder, given the dynamics, forcing & strong low-level jet of +55 mph.  Bits of 50-100 J/kg of elevated CAPE are seen in soundings, which (given forcing) is good for static in the colder, higher cloud tops & a thunder rumble.
