During the late winter and early spring, the reservoir of cold water known as the Great Lakes can cool surrounding areas considerably! Today, we shot into the 70s while much the big cities and suburbs to our east saw 60s. A northeasterly wind in March and April can bring our temperatures down by as much as twenty degrees. However, with water temperatures rising into the 50s now, the strength of that cooling will become confined to areas closer to the lakeshore. Still, as we know, that “cooler by the lake” phrase will be used quite a bit by our Meteorologist friends in Milwaukee and Chicago. However, in a few weeks, it will be pretty hard to get that cooling this far inland.
More importantly, will be the cold bursts of air from Canada…and there’s one coming for the weekend. Models are consistent in bringing a cold front through the area Saturday. Depending on the strength of the airmass behind it, temperatures may only top out in the lower 50s by Sunday…a far cry from this past weekend.
However, don’t fret. This is way out on Day-6 of our 7 Day Outlook. We could see this cold air modify a bit and even delay, which could cause us to bump up those forecast highs.
