Fresh layer of mountain snow giving way to warming temps

Wed., May 17, 2017, 1:17 p.m.

This week’s snow storm in the mountains of the region will give way to temperatures more typical of late spring, and that could lead to higher flows in streams and rivers as the snowpack starts to melt again.

The 5.5 inches of snow that fell at the Mount Spokane ski area on Tuesday had melted down to about 2 inches of new snow by noon on Wednesday, according to a web cam image of the measuring device there.

A strong area of high pressure is working its way onshore through the weekend, although the weather system may allow periods of showers on Thursday and Saturday.

National Weather Service forecasters are calling for mostly cloudy skies on Thursday with highs near 65 in Spokane and 63 in Coeur d’Alene with lows in the lower 40s.

Friday looks to be mostly sunny and warm with highs of 70 in Spokane and 67 in Coeur d’Alene.

Saturday may be showery with forecasters pegging the chances at 50 to 60 percent.

The weather turns the corner on Sunday with mostly sunny skies and highs of 75 in Spokane and 71 in Coeur d’Alene.

As is often the case this time of year, the Columbia Basin will be warmer, sunnier and drier.

Highs in Moses Lake might get to 80 on Sunday.

Next week, the weather warms up even more with highs in Spokane going to 77 and 79 on Monday and Tuesday.

Lows through the period will go from the upper 40s starting Thursday night to lower 50s next week in Spokane.

Forecasters said there is a good chance the warm weather will hold going into Memorial Day weekend.

One U.S. forecast model shows that high pressure and warm weather are possible through the end of May.

Forecasters said that the rain and new snow earlier this week combined with warming temperatures in the mountains may cause the streams and rivers to rise once again.

The normal high in Spokane for this time of year is 67 with a normal low of 44.
