Snow fell on parts of the US Northwest over the past weekend, just days before the first day of summer.
This upper-level weather system, originating in the Gulf of Alaska, has sent temperatures plunging well below average across the region. In the higher elevations, there has been enough moisture available for snow to coat parts of the northern Rockies and Cascades, said Chris Dulce, TWC meteorologist.
Officials in Idaho urged residents with recreational activities planned for the weekend to prepare for winter-like weather conditions and to be cautious of low visibility from blowing snow.

Daytime highs Sunday morning through Monday morning will be between 50s and 60s (10 to 20 °C) while nighttime lows on Sunday night will be in the 30s and 40s F (-1 to 10 °C) for all of East Idaho, the weather service said, as reported by the ISJ.
Frost that could kill vegetation was expected as the result, even in some lower elevation areas of the region such as Rexburg and Rigby.
