DISCUSSION…
Southeasterly winds early this morning will turn southerly through the morning hours as low pressure begins to take shape over the Plains into the Upper Midwest. The advancing low pressure system will ultimately set the stage for a much warmer day across the area today as afternoon mixing into a very mild airmass aloft (925 mb temps ~15C/59F) drives surface temperatures well into the 60s to low 70s this afternoon. The warming will occur even though cloudy conditions exist Wednesday morning. Temperatures warmed overnight during the early morning hours after a low of about 47°F around 1:30 a.m., and then a temperature rise of about 7 degrees to 54°F by about 8:00 a.m. Wednesday.

Through Thursday night…
Southeasterly winds early this morning will turn southerly through the morning hours as low pressure begins to take shape over the Plains into the Upper Midwest. This will ultimately set the stage for a much warmer day across the area today as afternoon mixing into a very mild airmass aloft (925 mb temps ~15C) drives surface temperatures well into the 60s to low 70s this afternoon. While a decent amount of sunshine is anticipated this afternoon, we are likely to see more clouds than sun for much of the morning. A few widely scattered showers are also possible around, or slightly after, daybreak in association with a weak mid-level impulse tracking northeastward over the area. It is not expected to add up to much, but don`t be surprised if you encounter a brief shower across the area early this morning.
Following an unseasonably mild night tonight, with lows only dropping into the mid to upper 50s, near record high temperatures into the low to mid 70s are forecast Thursday afternoon. However, this will come at the expense of increasingly gusty south winds during the afternoon as a potent storm system ejects northeastward from the Plains into the Upper Great lakes. While the unseasonably mild and breezy conditions will continue into Thursday evening, temperatures will drop sharply Thursday night as a strong cold front quickly sweeps eastward across the area. There also appears to be a good chance for a period of showers with the front Thursday night, particularly over my northern IL counties.
