Up and down temperature week ahead

Good Sunday to one and all. We have a seasonal brand of chill out there today, but a milder wind will blow as we head into the next few days. That’s the ‘up’ part of the temperature week. The ‘down’ comes later in the week.

Monday features 20s in the morning and 50s in the afternoon. Highs through Wednesday will be mild and can flirt with 60.

I will have a full update later tonight, so check back. Make it a good one and take care.
