Weather Outlook

Gusty Thursday Night into Friday

Rain Returns Late Week

Weekend Uncertainty

Weather conditions this week will continue to be mild and dry through Wednesday. Then the pattern will change for the latter half of the week with shift toward wetter conditions, cooler temperatures, and breezy winds

A cold front will bring gusty west winds expected Thursday night into Friday. Winds will be capable of resulting in difficult travel for high profile vehicles and may pick up lightweight objects. The cold front will come with little if any precipitation over the Columbia Basin and may result in patchy blowing dust and grass fire spread with the ongoing dry conditions.

There is moderate to high confidence for rain to develop in Idaho and portions of Eastern Washington Thursday. This graphic gives the probabilities for receiving a wetting rain (tenth or more). Uncertainty is in precise amounts with narrow bands of heavier amounts and exactly how far west the rain will setup.

There is moderate to high uncertainty with the weather pattern for the latter half of the weekend into early next week. 24-36 hours ago, many of the ensembles members were leaning toward low pressure over the PacNW but this has changed a lot leading to a lot of spread with potential outcomes from mild and dry to cool and wet.
