AgWeatherNet Weekly Weather Outlook for May 20 to May 26, 2017

Much Warmer Weather Expected for Early Next Week

Nic Loyd, Meteorologist, 509-786-9357

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, western Washington is also 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.
