Valley freezes are possible Friday through early next week across north-central Idaho and western Montana. If you’ve already started your spring gardening or turned on your irrigation, now is the time to prepare. Huge Caveat: There could be spotty clouds and/or a slight northeast breeze that could help prevent temps from bottoming out. Regardless, you should plan on protecting sensitive vegetation. Bring potted plants inside. Cover small fruit trees with fabric, not plastic. Disconnect hoses and drain sprinkler backflow preventers. Provide warm shelter and unfrozen water for animals.
