By tonight and early Wednesday the low in the lower Mississippi River Valley will combine with a low near Florida. As these two lows come together they will help push the jetstream further to the south but gain strength as they do. The low will then move north through the Ohio River Valley during the afternoon and eventually into Michigan by Thursday morning. Because the low will be developing in close proximity to our region the winds will be pretty gusty from the north/northeast Wednesday and especially Wednesday night into Thursday. Gusts could be as high as 40mph or better at times! This combined with the associated cloud cover and rain will keep temperatures in the 40s for both days!
The past couple weather model runs have actually been pushing the surface low further west closer to Chicago. Lake enhanced rain showers will be likely for the south shores of Lake Michigan where some totals could near the two inch mark. Closer to home around a half an inch to three quarters inch could be possible. Now if the low were to track a little further west the totals would go up as well. Overall, expect Wednesday - especially later in the afternoon and Thursday to be very raw days!
