PORTLAND -- Despite what may seem like an early end to summer, a return to warm, mostly dry weather is likely for much of September. The monthly outlooks calls for a warmer than normal September with near-normal to below-normal rainfall.

Thursday's rainfall of around .37 inches at PDX puts Portland above normal for the month with .78 inches so far.

Forecast charts continue to show hints of rain this Labor Day and possibly at times through next Wednesday.

We should not be surprised about the rain and thunder of the last few days. Historically, Portland's driest season runs from the July 4th weekend through roughly August 18.

Daily rainfall averages start to increase in the last part of August and continue to slightly build through September.

With that said, dry weather typically dominates around a few rainy periods until mid-October when Pacific flow patterns begin to wake up.

You will start to hear about winter forecast projections in the coming days and weeks. As usual, I will be publishing my winter thoughts in October.

In my opinion, August and September are simply too early to have great confidence in what the Pacific and Mother Nature have in store for Old Man Winter.
