What to Do Around the House This Week

1. Use the dry stretch: the chance of rain stays under 30 percent on Sunday, Monday, Tuesday and Wednesday. That is a good window for exterior painting, window washing or sealing a deck, since most paints and sealants need 50°F or warmer.

October Household Checklist

• Drain and store garden hoses, and shut off outdoor water lines before the first hard freeze.
• Test the heating system on a mild day so any repair is not an emergency call.
• Reverse ceiling fans to spin clockwise on low to push warm air down.

In Season at the Market

Produce that is typically in season across much of the country in October includes apples, pumpkins, pears, cranberries and brussels sprouts. Buying what is in season usually means better flavor and lower prices, so plan a few of this week's meals around it.
