Weather Eye: Days to stay mild, but thunderstorms might be on the way
Tuesday, September 18, 2012
Delightful late-summer weather continues with fair skies and warm daytime temperatures. The only drawback, of course, is the smoky skies, though they do contribute to some beautiful sunsets.
With an offshore flow of air from the northeast, afternoon highs reached 90 degrees Monday in many areas including mine here in Salmon Creek. Not too shabby for mid-September. Highs the rest of the week will be in the 80s. The weekend still looks fair, but forecasts show a low heading through to our south that could bring some interesting weather in the form of thunderstorms. We'll wait and see how that develops.
In contrast, freeze watches and warnings and frost advisories were issued for parts of the upper Midwest. Overnight lows were expected in the 20s, putting frost on the pumpkins for sure. It won't be long before we hear of snow flying in those areas. Not unusual for this time of the year?
Weather observer Tyler Mode of Battle Ground sent me an email Monday: "My average high through Sunday for September is 80.6 degrees. That's over five degrees warmer than my average high for July. Not only is the weather much drier this September, with the warmer temps I'm watering much more often. This is GREAT for the tomatoes though!"
Yep, that is right, great late-season weather for the local gardens and most likely lots of good stuff at the Salmon Creek Farmers' Market off Northeast 134th Street on Thursday. Enjoy nature's bounty while you can!
I want to mention that with the northeast winds, overnight low temperatures across the Cascades have been remaining in the 50s and 60s, allowing little relief from the extreme fire danger. If you are out and about, be very careful and be aware that restrictions are in place with most open flames.
