A large, slow-moving storm system is making its way across the region, bringing off-and-on showers and causing temperatures to stay low.
Treasure Valley residents will still get cozy glimpses of the sun through Memorial Day, but they should also prepare for rain, especially in the mountains, according to the National Weather Service.
High temperatures are predicted to be 5 to 10 degrees lower than normal through the holiday weekend.

This week, Tuesday’s high is expected to get up to 71 degrees. Wednesday will see the same predicted high temperature, but also some rain and possible thunderstorms in the afternoon across the valley. Temperatures are expected to dip down after Thursday with highs in the high 60s, according to the NWS.
The storm system is moving across Eastern Oregon and extends down toward the Nevada border and up toward McCall, said NWS meteorologist Dave Groenert.
NWS’ extended forecast Tuesday suggested Friday, Saturday and Sunday will be partly cloudy but without much chance of rain in and around Boise itself. But for those planning to camp, it’ll be important to pack for cold nights and possibly rainy days. McCall’s low temperatures will be in the high 30s and rain is predicted each day through Memorial Day.
