HOT AND HUMID MEMORIAL DAY WEEKEND IN CENTRAL ILLINOIS; T-STORM CHANCES ON THE DOWNSWING.
Springfield (WICS) - Muggy and warm conditions present this Saturday afternoon with ample sunshine to go with it. Thunderstorms our are hugging a boundary line in eastern Iowa, western Illinois, and eastern Missouri ahead of a cold front further to the west. These storms have occasionally been on the strong side near and around the Quad Cities, but haven't had much luck reaching severe levels further south in western Illinois. Our current severe weather outlook for central Illinois areas along and west of I-55 stands at a MARGINAL RISK. While a thunderstorm watch for the rest of central Illinois is not likely, the boundary containing scattered thunderstorms will reach us around 5-7pm. The scattered nature means that some will get wet while others not. The strongest storms of the bunch may have small hail and gusty winds. These storms will weaken near and after sunset meaning an end to this batch between 8-10pm tonight.
The cold front does sweep through Illinois early Sunday morning, means there'll be one last ditch attempt at squeezing out a shower or storms, but chances are very low. We'll take the edge off the humidity for the rest of the extended weekend. Dew points in the low to mid 60s still. Temperatures will remain in the mid 80s Sunday and increase to the upper 80s Monday. Should the humidity drop another notch, reaching 90 degrees on Memorial Day won't be out of the question. But the main story will be dry weather for Sunday and Monday.
Active weather resumes Tuesday with a chance for scattered storms. But finally this overly persistent active weather pattern will break down and clear Illinois Wednesday PM into Thursday morning. This will likely bring rain and storms to the area in this time frame. After that, dry and less humid conditions will be featured later Thursday, Friday, and into the first weekend of June with highs forecasted in the mid to upper 70s.

THE 7-DAY TEMPERATURE OUTLOOK: Look for highs in the mid 80s Sunday; upper 80s Monday; mid 80s Tuesday and Wednesday; and, mid to upper 70s Thursday through Saturday. Overnight lows will fall to the low to mid 60s Saturday through Wednesday night; upper 50s Thursday night; and mid 50s Friday night.
