FOX 6 Weather Notes

From FOX 6 Chief Meteorologist Vince Condella

 

Latest forecast model runs showing similar solutions for the next few days.  Still looks like a great Thursday with mainly high, thin clouds to filter the sunshine.  I'll bring in some showers late Thursday night, after midnight and towards dawn Friday morning.  Then during the day on Friday, with higher dewpoints in the 60s and diffluence aloft, look for scattered showers and thunderstorms to pop-up.

 

Biggest uncertainty for me is the Saturday forecast.  I think we'll see some widely scattered showers here and there, but otherwise a partly sunny day.  There is some cyclonic curvature to the upper air flow in the GFS model with some vorticity (spin) coming our way at 500mb (approx. 18,000 feet above the ground).

 

Sunday through Tuesday looking good as surface high and upper air ridge settles in over the western Great Lakes.  Weak pressure gradient so we can expect lake-breeze to kick in each day.
