Happy Mother's Day, Chicagoland!
And what a gift from the weather, as we have a sparkling, sunny Sunday on tap. In fact, it even calls for the use of sunscreen if you'll be outside for prolonged periods.
Abundant sunshine and no rain is in the forecast, with high temperatures inland possibly reaching the mid-70s in some locations. It'll remain cooler lakeside, however, with an east/southeast breeze keeping highs in the mid-60s near Lake Michigan.
And there's more mild May weather in the forecast all this coming work week, with several days projected to reach the 80s, or close to it (see more below).

After high temps approach 80 inland on Monday, the extended outlook calls for more clouds on Tuesday, with a chance of showers and thunderstorms, some possibly strong to severe.
We'll certainly keep an eye on that as Tuesday approaches.
Temps dip a little Tuesday with the cloud cover, then the warmth builds again, with Thursday looking to be the warmest day of the coming week at this point. Highs forecast in the mid-80s could make it the warmest day of the year so far, but the warm temps also bring the possibility for strong to severe storms again on Thursday.
It'll continue to remain cooler by the lake all week, however, but still pleasant.
Around the U.S., temps soar into the mid-90s by Sunday in the northern Plains, and then 80s take over the eastern U.S by next week, with 90s showing up in the Southeast by late next week.
Intense heat develops across the Lone Star State, as Texas goes into the 100s as a summertime ridge over the Southwest U.S. is pushed eastward.
A huge area of much warmer than normal temperatures, as much as 17 degrees above normal, is set to take over portions of the Dakotas.
A pattern change is being hinted at, as a transition to much cooler than normal weather is shaping up across Canada and the Rockies, with the warmest air relative to normal shifting east.
A huge area of 2 inches or more over the next seven days, with even higher amounts in the 4- to 6-inch range, is expected across Florida and Georgia.
