Next Friday is Halloween, which begs the question: Is a frightful forecast in the cards for the final week of October? Read on to find out.

A wild weather weekend is on its way, as a potent low pressure system swings northward along the coast on Saturday. The main impacts of the storm will be significant rainfall in western areas of Washington, along with very windy conditions. In fact, western areas may receive two rounds of wind. The first round is likely to occur tonight into Saturday morning, as offshore pressure gradients induce strong east winds around the Cascade west slope foothills in places like Enumclaw. The second round should arrive in the form of southwesterly winds later on Saturday, as the main cold front makes landfall.

Interestingly, temperatures should also be quite variable. On Saturday, easterly flow may keep central areas from Yakima to Omak rather cool, even as temperatures surge under warm southeasterly winds in eastern border areas such as Pullman. Winds are expected to pick up east of the Cascades later on Saturday, and then continue into at least Sunday morning, with lingering showers in the west. Temperatures behind the cold front will be much cooler in eastern border areas and in the mountains compared to Saturday. Meanwhile, the increased mixing in central areas should limit their potential cooling. On Monday morning, the frost potential east of the Cascades will increase to a moderate level for the first time in a long while.

Another storm will take aim on the region later on Monday, before passing through the state on Tuesday. Rain and breezes should develop at the coast later on Monday, before spreading inland on Monday night and into Tuesday morning. Later next week, more soggy weather is possible in the west, although the east could potentially dry out. In any case, all areas should be milder relative to early in the week.

  • Warm in the east on Saturday. Cooler on Sunday.
  • Cool on Monday, and then becoming milder next week.
