The Week Ahead – Here Come’s the Sun, but will the Smoke Stay Away?

What a wet start to Autumn. While we didn’t tally anywhere close to the ~8 inch monthly precipitation record (at Snoqualmie Falls) for September, it did rain 4”.  That's the third wettest over any 3-day period in September.  Had it not been for the dry first three weeks of the month we might have threatened the monthly rainfall record.  Now let us talk about the big warmup on the way!   A building ridge of high pressure should dominate, potentially sending highs into the 80°’s by mid-week.With October fast approaching, this does beg the question if we’re going to break any heat records this week.  I was initially surprised by my finding.   Not Likely.  Turns out there was a massive thermal trough that sent the mercury to a blistering 95° on 10/1/1987. To check the likelihood this might be an error, I looked at official records at Sea-Tac on that day.  89°!  So probably legit (within acceptable margin of error).  I’d appreciate hearing from any of you living in the Valley that recal…

The Week Ahead - Want Rain? Careful What You Wish For

Update - 9/22/20:We're bracing for first major storm of the season as it pushes onshore Wednesday morning.  Lot's of wind and rain.  In fact, per Euro and NAM latest main model runs, I'm upgrading our wind gust prospects Wed afternoon and Fri inland, 30-40 mph+ gusts out of the S/SW possible in Snoqualmie Valley vicinity. With all the leaves still on trees, there may be intermittent power outages.A second round of atmospheric river should develop over the weekend, keeping things wet.  By weeks end, we're talking potential 5+" of rain for late September!Longer range still hints and pulling a complete 180° next week with unseasonable warm and sunny weather.  Looking forward to that!Original story - 9/20/20Now that we've all taken that deep breath of fresh air, more active weather is wasting little time arriving at our doorstep, and just in time for the first week of Autumn.  Autumn begins Tuesday, September 22nd, when the Sun crosses the celestial equator from n…

Well I sure was envious looking at that 85° sunshine on the TV set this morning. Go Hawks!Fortunately, relief should be near for our current smoke situation. Smoke was barely thinning aloft to end the weekend.I noticed a sun almost too bright too look (at times), and it didn’t totally disappear after 10 am like yesterday, so that was a plus I guess.Cough cough.. While air quality is still terrible and smoke remains trapped at the surface, we should slowly improve tonight, with the positive trend continuing into Monday and Tuesday.As an upper ridge shifts inland Monday, an increasingly moist SW flow may bring a few showers Monday into Tuesday, though models have backed off as far as getting much if any precipitation.  Still, stronger onshore push associated with this frontal system should help to clean up the air quality.We will be in between frontal systems Wednesday, but with continued winds from the south, the smoke may make a brief return.  Though hopefully we won’t have the smoke s…
