Sunny Thursday, 61 — then Friday night drops to 30

Thursday is a good one: sunny, high near 61, with a north breeze around 12 mph. Tonight stays clear, then areas of frost develop as the low settles near 34.

Friday is the transition day. Widespread frost in the morning, then sunshine and a cooler high near 57 with light north winds. But Friday night is the one to prepare for: widespread frost and a low of 30 — the coldest of the season so far. Bring in tender plants, disconnect hoses, and let outdoor faucets drain.

The weekend rebounds in stages. Saturday starts with widespread frost, then turns sunny with a high near 59 and a light northwest breeze; Saturday night dips back to 30 under clear skies. Sunday shakes off another frosty start for sunshine and 63 — the warmest afternoon of the stretch — with nearly calm winds. Sunday night clears to a low around 35 with patchy frost.

Monday brings a mild finish: patchy frost in the morning, then sunshine and 66, the warmest high in the forecast.
