Weekend weather for the 17th to the 19th of May. Friday and Saturday are clear, Sunday is very tough to call. On to the forecast!
Friday will start wet, and for Kirkland specifically, things could be very wet with a Puget Sound Convergence Zone forming overnight. The question with the CZ is always where exactly. The further north you are of the King-Snohomish line, the more likely you’re in the wet, but it is possible for the zone to form a little further south. If you’re south of downtown Bellevue and Seattle, the rain will be lighter and turn to showers earlier in the day. Friday afternoon looks, “OK,” and Friday night dries out further.
Saturday we get an onshore flow, the same wind direction that gave us our mini-heatwaves in March and last week. We won’t see temperatures soaring into the 80s, and it will be mostly cloudy, but it will get into the 70s with an increasing chance of rain on Saturday.
Sunday – this is the tough forecast. Models are all over the place on how much rain but it will rain. Most of it will be during the overnight hours and should be lighter than the rain we’ll see tonight and Friday morning. We then have a general chance of rain and “normal” May weather out until Tuesday of next week. Given how wide apart the models are, I’ll make another call on Sunday tomorrow and update.
For weekend outdoor plans Saturday is your day – won’t be bright blue skies but it will be dry.
