Weekend sunshine on repeat: the final day of February finished off with--what else?--blue skies and mild temperatures. It has looked and felt more like spring than winter all month, so why should Saturday be any different? That dominant area of high pressure is still sitting over the Eastern Pacific, detouring all of our usual wintertime clouds and rain (and mountain snow, too) far north into the Gulf of Alaska. As such, highs climbed well into the 50s for most of Puget Sound on Saturday, with some spots near the coastline closer to 60°. Thanks to the abundant daily sunshine, February was the warmest on record (average temps) for SeaTac.
Sunday marks the beginning of a new month, but the weather will remain the same for the first of March. It will be chilly again at sunrise, with most communities starting the day near the freezing mark. Some locations in the South Sound will temporarily dip into the upper 20s, and we may see some patchy fog or frost. By afternoon, we'll have thawed out into the 50s again--a great day for getting out in the garden or hitting the hiking trails.
A weak disturbance will break through our high Sunday night, increasing the clouds by evening. Some light rain will fall overnight and into Monday morning, so look for some wet pavement for the first early commute of the week.
However, after that system rolls through, the high is back again, and we'll see a long string of partly to mostly sunny days for the rest of the work and school week. Early morning lows will be chilly, but highs will stay mainly in the 50s, which is about average for this time of year.
Have a great weekend,
