Patchy Frost Tonight In Part of Area……Friday-Sunday Forecast (Including Details of 5K Challenge Forecast)April 12th, 2012 at 2:55 pm by Chad Evans under Chad's WLFI Weather Blog
Very dry air, calm winds & a developing low-level inversion (lid) will make for patchy frost in the eastern 70% of the viewing area. Lows will vary from 31 in the east to 41 in the southwest with 35 at Lafayette, 36, Crawfordsville, but 31 at Burlington, Logansport & Kokomo. Perrysville & Pence are headed for 41.
Clouds will increase Friday with a few showers possible (mainly in the p.m.) with only 30% coverage. It doesn’t look like a big deal & some of you will not see a single drop of rain Friday.
Two waves of scattered showers & t’storms are still on the way for Saturday.
One wave of rain will pass in the morning in the 6 a.m. to 11 a.m. time frame with 70% coverage, followed by a break with some sun. In fact, it looks pretty good in that midday to 5 p.m. time frame with warm, humid conditions, strong south winds to 35 mph & sunshine mixed with clouds.
Then, another wave of scattered showers & t’storms is possible Saturday evening with 40% coverage. With 40% coverage, not everyone will see rainfall.
Once that wave passes, Saturday night looks mainly dry with partly to mostly cloudy skies & lows of only 58-62 with a brisk south wind.
On Sunday, a wave of scattered showers & t’storms will pass in the late afternoon to evening with 40% coverage. Right now, it looks like that 40% coverage will be confined to our western & northwestern counties.
After this, another break will ensue with partly to mostly cloudy skies Sunday night with a brisk south wind & lows of only 60-64.
A wave of showers & t’storms will pass Monday morning to midday, followed by sunshine & windy, warm conditions. In the evening, a narrow, broken line of showers & t’storms is possible along the actual surface cold front.
Interestingly, it is this Sunday-Monday storm system that may produce substantial accumulating snows in Minnesota & Wisconsin with an icing event in northern Michigan to central Ontario & Quebec.
Behind that, colder air will rush in for Tuesday.
