From A Freeze to Air Conditioning Weathe

Overnight temperatures will drop to near critical levels for a short time between about 3 AM and 7 AM…but only in the coldest parts of the Rogue Valley and surrounding valleys west of the Cascades.

The coldest orchards will see temperatures between 29 and 32, with most orchards 32 to 36.  This will NOT be a widespread “Hard Freeze” across Southwest Oregon, but sheltered locations that are prone to cold pockets will see the coldest temperatures.

Ironically, by the afternoon, highs will be in the upper 70’s…while the highs on Thursday through the weekend will be in the mid to upper 80’s.  This will likely require many to turn their air conditioners on for the first time.

There will be a couple of days where the Chetco Effect will be most prominent.  Wednesday and again Saturday and Sunday.  Winds will be brisk from the northeast to east over the ridge-tops, pushing the air (and compressing it–warming it up and drying it out) near Brookings.  All coastal communities will enjoy sunny days…as the marine layer will be pushed mostly out into the Pacific, with low clouds not expected to return until early next week.

There is a slight chance that early next week a weak storm will bring up a little moisture and produce some isolated mountain thunderstorms.  Cooler temperatures will follow the moisture on Tuesday.
