Rumble of Thunder or Two Possible Tuesday MorningFebruary 25th, 2013 at 10:05 pm by Chad Evans under Chad's WLFI Weather Blog
Temperatures are generally around 33 area-wide with stiff east wind bleeding in dry air. Despite precipitation echoes just to our south, do not count on anything until early Tuesday morning, generally 5a onward. The wedge of dry, chilly air bleeding in will tend to make for virga (precipitation evaporating before it hits the ground) until early morning when low-levels moisten up enough after the virga.
Freezing rain, sleet & perhaps bit of snow will overspread area in the morning. It will tend to change over to rain after 10 or 11 a.m.
Be aware of minor accumulations of freezing rain, sleet & snow at less than 0.5″ north of I-74 with strong east-northeast winds to 32 mph at times.
Given impressive dynamics & forcing, I would not rule out a rumble of thunder or two in the morning.
After rain, there will be a gradual changeover to snow with periodic snow up to Thursday. 1-3″ looks good for almost everyone with 3-5″ in the far north.
Periodically, strong winds of up to 35 mph will pass during this period.
We need to watch & make sure that heavy snow does not make it in here from Illinois, increasing totals in the area. We also need to watch to make sure changeover to snow is not sooner. We are near the edge of where heavier snowfall will occur. Stay tuned as this system continues to evolve. Storm track has not changed today, but we will let you know if it does begin to do so & bring more in the way of snowfall to the area.
