An approaching system brings more warm temperatures and scattered rain/storms to the viewing area.
The further south you are, the more likely you are to stay dry Sunday.
A warm front passing through will push afternoon highs into the 80s and low 90s Sunday and Monday. Low temperatures will only be around 70 degrees Sunday night. Winds will be out of the south at 10-25mph, with gusts around 30mph. Some passing storms may have higher gusts.
Low pressure will be passing to the north of us in Canada, and it's accompanying front will stall over the straits area.
This will cause scattered showers and thunderstorms to remain in the forecast for the northernmost counties Sunday, and then become more widespread Monday and Tuesday as the system passes.
So how much warmer are we than normal? About ten to fifteen degrees! Highs for this time of year are normally in the low-mid 70s, while low temps are in the low and mid 50s. We look to cool down a little bit towards the end of the workweek.
