A surface cold front passed through on Monday afternoon, leaving cooler, drier air in its wake. Tuesday morning winds should be light and out of the north and the cooler air should pool in low lying areas (like along the Illinois River for example). Models seem to be running a bit high, so will go upper 30's for the low. Flow should begin to switch again to the south-southwest as the day progresses, returning some moisture to the area and moderating any heating under the clear skies. Again, thinking models are overestimating the high temperature, so will go low 60's.
As the week progresses, large surface low moves across the mountains infront of an upper level trough. Surface cold front should pass early on Wednesday and then high pressure should settle in with much cooler, and much drier air.
