Cover your plants Wednesday night: The National Weather Service has released a frost advisory for the Treasure Valley.
Lows Wednesday night will hover in the mid-30s, reaching near-freezing temperatures, according to the NWS. Calmer winds and mostly clear skies will contribute to the unseasonably low temperatures.
Even if frost doesn't form, the temperatures alone could damage sensitive plants, the NWS warned.
Wednesday morning brought a low just two degrees above freezing; the projected high for the day is in the 50s. A cloudy sky and light drizzle only added to the chill. Looking ahead, Memorial Day weekend should be more temperate for travelers or those planning to spend the holiday outdoors. The weekend should see sunny skies and highs in the 70s.
Memorial Day will be overcast, but temperatures will rise almost to 80 degrees.
