NOAA Storm Prediction Center: Watch Likely Soon For Parts of Area (80% Chance of Watch Issuance)January 29th, 2013 at 8:16 pm by Chad Evans under Chad's WLFI Weather Blog
Despite slight weakening trend in squall line recently, low-level jet is forecast to strengthen rapidly over the next 1-2 hours into the area at +80 mph, which may help squall line to re-organize. SPC is onto this thinking.
Whether is watch is for our area, part of it (now or in a bit) or for areas mainly to our southwest remains to be seen.
Sporadic wind threat & perhaps an isolated weak, brief tornado threat still looks reasonable, generally in the 9 p.m. to 12 a.m. time frame. HOWEVER, dew points remain issue at only 56 at the station with air temperatures of 63 degrees as of 8:38 p.m.
Substantial WAA (warm, moist air moving north) with its 60-degree dew point line is moving north. Need to watch this. 60-degree dew point needed to really get anything to the surface as tongue of 60-degree dew points creep northward.
Regardless, heavy storms are lining up just west of our northwestern counties. It will be interesting to see what happens with this line as the +80 mph LLJ gets going in the area.
We are getting some pretty good gusts with the storms just north of Roselawn of up to 54 mph. Velocity showing gusts of 30-40 mph northwest of Morocco.
