Bundle up, Jefferson County. A cold, dry air mass is settling over Central Oregon this week, bringing the season's most significant temperature drop so far — and raising the possibility of hard freezes overnight through the weekend.

According to forecasts from KTVZ and the National Weather Service, daytime highs are expected to remain in the low to mid-50s across the Madras area, while overnight lows could plunge into the teens and 20s — cold enough to freeze exposed pipes, damage unprotected crops, and create icy conditions on roadways by early morning.

A Historically Dry October

The cold comes on the heels of what forecasters are calling a historically dry October across Oregon. With little soil moisture to buffer temperatures and no significant precipitation in sight for interior Central Oregon, the impact of overnight cold could be sharper than in wetter years.

Hopes for meaningful fall rain have largely faded. While there's a chance of precipitation reaching the Oregon Coast and Coast Range, the high desert areas of Jefferson County — including Madras, Culver, Metolius, Crooked River Ranch, and Ashwood — are expected to remain dry through at least the end of the month.

What You Should Do Now

With freeze conditions possible as early as tonight, Jefferson County residents — especially those in rural and agricultural areas — should take action:

  • Farmers and ranchers: Protect late-season crops, insulate irrigation lines and water troughs, move livestock to sheltered areas
  • Homeowners: Winterize outdoor faucets and exposed pipes before they freeze; disconnect garden hoses
  • Gardeners: Bring in potted plants, cover frost-sensitive landscaping
  • Heating systems: Test your furnace, wood stove, or propane system now — don't wait for the coldest night
  • Vehicles: Stock emergency supplies for rural travel; check tire pressure, which drops in cold weather

Road Conditions

Overnight freezing temperatures can create black ice on U.S. 26, U.S. 97, and rural Jefferson County roads — particularly in the early morning hours before the sun has a chance to warm pavement. Motorists should slow down, increase following distance, and check TripCheck.com before traveling, especially on shaded canyon roads and bridges.

Burn Season Reminder

Residential outdoor burning remains open in Jefferson County, as the seasonal burn restriction was lifted on October 1. The dry, cold conditions this week could increase fire spread risk if winds pick up. Always check the Oregon DEQ Air Quality Index before burning, and never burn on days with gusty or erratic winds.
