Quad Cities, Illinois – Persistent mist and light rain will continue to impact the region through tonight, bringing accumulation totals between 0.25 and 0.50 inches. This damp pattern is expected to shift by Tuesday, giving way to a mix of clouds and temperatures reaching the 60s.
According to the National Weather Service , the current precipitation will taper off during the early morning hours on Tuesday. Temperatures tonight will remain cool, ranging from 50 to 57 degrees. As the system moves out, the middle of the week will see a gradual warming trend with daytime highs climbing toward the 70 degree mark by Wednesday and Thursday.
Commuters should plan for slick road conditions during the early morning hours on Tuesday while the light rain persists. Although the heaviest activity is expected to exit by sunrise, lingering dampness on secondary roads may still impact travel. Visibility could be locally reduced in areas of dense mist or fog overnight.
Conditions will improve by midweek as cloud cover breaks for more sunshine. Monitor local updates to see if temperatures reach the projected 70 degree high, and prepare for a shift in outdoor activity plans as the drier air settles over the Quad Cities.
