Rain returns Wednesday but here's what you can expect for the holiday weekend

Posted at 4:11 AM, May 21, 2024

Sunshine and pleasant conditions are with us on Tuesday with high temps near 70° and lighter wind than on Monday. Clouds will be on the increase as the sun sinks low in the western sky Tuesday evening.

A cold front will cross the valley in the predawn hours of Wednesday bringing rain behind it for the Treasure Valley reaching Ontario by midnight and Boise by 3 am. In the later morning through the mid afternoon showers will mix with a few developing thunderstorms containing locally heavy downpours and pea-size hail. The valley could see a quarter to a half inch of rainfall. It will be unseasonably cool with a high temp of only 60°.


The central mountains will see rain with rapidly lowering snow levels on Wednesday. 1"-2" of snow is possible in McCall from late Wednesday through Thursday morning. Elevations above 6500 feet could see 2"-4" with 4"-8" above 7500 feet. The high temp in McCall will barely reach 45°

Cool conditions will linger into Thursday with a high temp only in the low 60s again. It will be partly cloudy with a cool breeze.

Friday is my pick day of the week! I expect sunshine, light wind, and a high temperature in the low to mid-70s. That's very close to normal. A perfect day for outdoor activities.

Another system moves in on Saturday will temperatures cooling back into the mid-60s with a cool breeze and there is a slight chance of showers. In the McCall area and other central mountain locations around 5000 feet, you can expect rain showers developing otherwise mostly cloudy and quite cool with a high temp of only 50°

On Sunday the valley will see nicer weather with the temperature right around 70 with sunshine and lighter wind. The McCall area will only warm to the mid-50s but sunshine should be on the increase. Low temperatures will drop to 29° Friday morning, 36° Saturday morning, 28° Sunday morning, and 34° Monday morning.

Monday will be warmer for all areas with sunshine and pleasant conditions. Boise will hit 80° and McCall 66° for afternoon high temperatures.
