High pressure is sliding off to our east, weakening it’s grip on us. Consequently, we’ve seen south winds increasing through Thursday and CNY gets on the back side of that fair weather maker. As the high moves farther away from us, clouds will thicken over us, which will keep temperatures quite a bit milder tonight.
Looking back to the west, there isn’t much in the way of rain. While a brief shower can’t be ruled out through the first half of Friday, chances for showers and thunderstorms will increase later Friday and early Friday night.
A greater chance for showers will be with us this weekend, in particular, Saturday. The increased shower threat will be in response to a powerful cold front diving southeast from Canada. This cold front is forecast to be located over the central and eastern Great Lakes region by Saturday morning. We should manage to reach the 70s before the colder air arrives Saturday as winds will remain south to southwest before the frontal passage.
Once the front moves through, much cooler air will filter into the region for Sunday and Monday. The combination of chilly air and warm Great Lakes water will mean lake effect rain showers Sunday and Monday. Highs both days will likely struggle to reach the low 60s.
