Tonight: Any stray shower or thunderstorm that does occur in the area will taper off this evening. Most areas will experience mostly clear skies with calm conditions overnight. The coast will see areas of thick clouds and fog developing after the midnight hour due to the presence of a marine layer. Overnight low temperatures will fall into the upper 50s to low 60s west of the Cascades with temperatures dropping into the low to mid 50s east of the Cascades.  

Tomorrow:  On Wednesday afternoon and evening, we'll have a better chance at spotty to scattered thunderstorms for the eastside and Northern California. The Cascades and Siskiyous could also see a few thunderstorms. The severe threat looks low, but lightning will be a concern when it comes to new fire starts. The Rogue Valley will stay dry with mostly sunny skies. Skies will turn sunny with quiet weather along the coast. Highs tomorrow will top out in the upper 80s to lower 90s in our westside valleys with upper 80s in the Klamath Basin and 60s to around 70° along the coast.

A RED FLAG WARNING has been issued for much of Klamath County and Lake County as well as western Siskiyou County from 2 PM - 11 PM on Wednesday. During this time, scattered thunderstorms may produce abundant lightning and gusty winds over dry fuels creating dangerous fire conditions. New fire starts are likely and new/existing fires could spread quickly. Use caution east of the Cascades on Wednesday.

Extended:  On Thursday, a cold front will bring some increased clouds, breezy winds and cooler temperatures to the region. A few showers will be possible near the coast. 

Starting Friday and into the weekend, temperatures will start rising again. The coast will see sunny skies and blustery offshore winds that'll help crank temperatures up. By Sunday, highs in Brookings could top out in the lower 80s. Inland temperatures by Sunday will heat up into the 90s for much of the region. Monday will be the hottest days with highs in Northern California in the upper 90s to lower 10s. We'll have to keep an eye on early next week for at least the slight chance for more thunderstorms.
