A major storm looks to bring strong winds and heavy rain to much of the region this weekend, along with notable night-time warming from Saturday night into Sunday morning. Rain should rapidly spread eastward on Saturday morning, but may then taper off on Saturday night in central areas, and on Sunday morning in eastern Washington. Western locales could maintain wet weather for a longer duration, though drying is anticipated to occur later on Sunday.
For early next week, much calmer weather is likely, with mild, pleasant days and cool nights. In such a pattern, morning fog should be the main potential concern at that time. It appears that a clipper-type system will traverse the region on Wednesday, although its influence is expected to be modest compared to this weekend’s storm. Clouds and even light western rain are possible, although increasing wind is forecast to be the predominant feature of note. Variable weather seems likely to continue later in the period, as high pressure attempts to rebuild across the Northwest. Overall, a dynamic and changeable weather interval is expected in the coming days, with impactful weather likely this weekend.
Here are the key points:
• Widespread rain this weekend, with heavy totals in the west and especially in the mountains
• Mountain snow on Saturday morning
• Very windy at times this weekend
• Cool on Saturday morning, and then significant warming by Saturday night and especially Sunday
• Calmer, drier, and more benign weather early next week
• Weak storm possible on Wednesday
Specifically for Western Washington:
• Normal conditions for this time of the year would be highs in the mid 50s to low 60s and lows in the upper 30s to mid 40s.
• Rain, heavy at times, through mid day Sunday.
• Highs in the 50s to low 60s on Saturday, and upper 50s to 60s on Sunday.
• Lows in the 40s on Saturday morning, and upper 40s to 50s on Sunday morning.
• Mostly dry overall. A chance of rain on Wednesday.
• Highs in the 60s on Monday, and cooler later in the week.
• Lows in the mid 40s to low 50s early, and then warmer, and possibly cooler later in the week.
