Welcome to Saturday night and Memorial Day weekend, Motown.

I know it’s almost June. It’s Memorial Day Weekend. But, we are talking about frost alerts and chilly conditions tonight. Tomorrow, relief arrives in the form of higher temperatures, and it gets warmer Memorial Day.

We’ll need to turn our heaters on again Saturday night. It will be clear and chilly. Overnight lows will be in the upper 30s to low and mid 40s.

Sunday will have blue skies returning, and it will be milder. We’re getting closer to beach-weather with afternoon temperatures near 70 degrees. This will be better for a walk along the shore as opposed to going in the water.

Welcome to Memorial Day, Monday. The weather will be wonderful for morning parades and commemorations; same for afternoon and evening ones. We start with temps in the 40s and end up with highs near 75 degrees.

Tuesday will be mostly sunny and warm. For the first day of June, this is pool-weather with after-school temps in the upper 70s.

Wednesday will be warmer with highs near 80 degrees. Skies will be partly sunny with a chance of showers.

Showers are possible, again, Thursday and Friday. It remains warm with highs near 80 degrees or more after morning lows in the 50s to near 60 degrees.
