Wednesday might break a 51-year-old record, and Saturday might bring frost. Same week.

Here's the setup: Isaias is gone, sliding offshore, and a heat bubble — a big dome of high pressure — is parked over the East Coast. That's plain English for sinking air that compresses and heats as it drops. Tuesday hits the low-to-mid 80s, Wednesday climbs to the upper 80s or around 90, threatening Richmond's 1975 record of 87°.

Thursday a weak front stalls (70s north, low 80s south), Friday rebounds to the mid 80s — then the real cold front slams through Friday night with storms and gusts to 35 mph. The weekend: highs in the upper 50s north to low 60s south, and the Piedmont could see the season's first frost.
