Subtle changes on the way
A weak storm off the coast is going to gradually move toward Idaho over the next few days. This will slowly cool our temperatures, bring a few afternoon showers along with a chance of isolated thunderstorms. As disturbances go, this one is fairly weak. However, once it starts moving into the region, it will be slow to move through.
You’ll notice very little change on Wednesday. It will be warm with highs in the 80’s. However, we might see a few late afternoon spotty showers and storms. The best chance for this will be in the Lower Treasure Valley. On Thursday, we’ll see a mix of sun and clouds with highs in the 70’s. Friday will be the coolest day of the week as the center of the low tracks over the state. This too may trigger some spotty showers or storms. Highs will be in the 60’s.
By Mother’s Day weekend, the low will inch into Utah, Wyoming and Colorado. Right now, it looks like we’ll see a mix of sun and clouds Saturday with highs near 70. By Sunday, drier air will start to move in from the northwest. As a result, we’ll see partly cloudy skies with highs warming into the mid 70’s.
The cooler temperatures will help to slow the flow into our reservoirs. It would be nice to preserve as much high elevation snowpack as possible. The temperatures have been way too warm averaging 10-15 degrees above normal for the last week. Temps in the 70’s will feel nice.
