It's a mild Monday morning, with temperatures in the upper 40's and low 50's. It will feel a bit damp today with drizzle and overcast clouds on and off through the day. There is potential for a few isolated to widely scattered showers through the afternoon, but there will be a CAP on the atmosphere and that will make it harder to produce any rain or storms. However, more forcing will arrive tonight ahead of an incoming cold front, and storms will be more likely closer to 7pm tonight.
Storms will develop to the west, potentially as individual cells west of the area in central Iowa. Storms will congeal into a line in eastern Iowa and will continue to march east across northern Illinois. Timing will be around dinner time tonight, between 7pm to 11pm this evening. We will watch for potentially strong straight line winds in the line of storms, along with moderate to potentially heavy rain at times. Strong wind producing storms will be the most likely along the Mississippi and west today, with storms weakening as they head east. Western counties are included under a Slight Risk for strong to severe storms tonight, and the rest of the Stateline is under a Marginal Risk. Behind the front skies will clear rather quickly, but winds will strengthen out of the WSW into Tuesday morning. Tuesday will be sunny and mild but very windy. WSW winds have the potential to gust over 40 mph through the afternoon. With relative humidity dropping there will be somewhat of an elevated fire danger, and high profile vehicles will have difficulty driving at times.
