Windy Sunday afternoon

Temperatures Saturday topped out in the upper 30's and low 40's.  Not bad even if it was below average.  That's all about to change Sunday as strong southwest winds will bring in somewhat of a warmer air mass, but it's not necessarily going to feel all that warmer on Sunday.

Strong low pressure will remain tied to the U.S/Canadian border Sunday afternoon.  A warm front will lift through southern Wisconsin and northern Illinois, followed then by a cold front Sunday evening.

Moisture will increase some Sunday morning ahead of the warm front and this could lead to a quick burst of a wintry mix - sleet, freezing rain & snow - between 6am and 9am, before switching over to all rain mid-morning Sunday.  Heads up if you're going to be traveling early on Sunday. 

Wind gusts by Sunday morning will already be approaching 30 mph and will increase through the afternoon with gusts close to 40 mph.  The wind will ease a little once the cold front passes Sunday evening, but there will still be an occasional wind gust near 20 mph through 8pm Sunday night.

While the surface low pressure will be far away from the Stateline, there may be just enough energy in the atmosphere to generate a thunderstorm or two midday Sunday.  So, keep your ears open for that.  The start of next week won't be nearly as windy, and temperatures will warm into the low to middle 50s - closer to average for this time of year.
