Memorial Day Weekend Not Totally Dry!

A weak weather system will bring a few showers overnight and early in the day on Friday.  High pressure will result in mild, but slightly cooler than normal temperatures the next several days…along with mixed sun and clouds Friday afternoon and again for most of Saturday (I’m thinking of the Boatnik Festival and Parade).

However, some showers will develop in the afternoon and evening on Saturday, then continue as occasional showers…with breaks of sunshine Sunday.  A stronger weather front will bring more widespread rain and showers to Southern Oregon and Northern California on Memorial Day.

The pattern for the Northern Hemisphere has shifted in the last 5 to 10 days, resulting in cooler and wetter weather for the Pacific Northwest and parts of Northern California.  The long range computer models and the other techniques I use to predict long range trends…all indicate a cooler and wetter weather pattern continuing into the end of May and possibly for some of June.

Although the forecast for the Summer is near normal temperatures and dry weather for the Rogue Valley, the cooler start to June (officially the Meteorological summer) would not be unexpected.  As I explained yesterday in my Summer Outlook, east of the Cascades in the Klamath Basin and south of the Siskiyou’s in Northern California, the closer proximity to the predicted hot high pressure zone…will keep Klamath Falls, Lakeview, Alturas, Mt. Shasta and Yreka slightly hotter than normal for the summer months (average of June, July and August).

All areas are forecast to be drier than normal.  But, when you consider that June, July and August are the driest months of the year, drier than normal is relative.

The good news with this prolonged period of precipitation and cooler than normal temperatures I see going through at least the end of May and possibly into early June…puts off the start of the extreme danger of the fire season a little longer.  Any rain and cooler weather we can get in May and early June is a bonus.  Especially since we started off 2013 with the second driest ever January, February and March…then continued the excessive dry weather in April and at least the first half of May.
