The main weather headline in the coming days will be much warmer and summer-like conditions, as a large ridge of high pressure becomes the dominant atmospheric circulation feature over the Northwest. Given the expected ridge placement near the coast, along with potential offshore flow, even western Washington is expected to be quite hot early next week.

Aside from a slight chance of showers in far eastern areas on Saturday, and again in western areas later in the period, mainly dry conditions are anticipated.

Temperatures should be warming to well above normal levels by early next week, and then may cool down later in the period, especially in the west. Any significant cooling later next week would likely arrive with breezy conditions, but there are a large range of possible scenarios at present. Some models show no cooling through next Friday, while others suggest at least a brief interval of appreciable cooling. The current forecast splits the difference, and calls for slight cooling sometime later next week, although there is still notable uncertainty.

In any case, another round of very warm weather is coming through at least early next week.

Normal conditions for this time of the year would be highs in the 60s to around 70 and lows in the mid 40s to around 50.

Weekend — Mostly dry. Highs in the upper 60s to mid 70s on Saturday, and 70s to mid 80s on Sunday. Lows in the mid 40s to mid 50s.

Next Week — Mostly dry. A slight chance of showers later in the week. Highs in the 80s early, and cooler later in the week. Lows in the upper 40s to 50s on Monday morning, and then warmer, and possibly cooler later in the week.
