KEY POINTS... * No impactful weather expected through the 4th of July holiday weekend.

* Mild temperatures and enhanced afternoon breezes will continue through Thursday. Nightly return of clouds west of the Cascades will give way to sun in the afternoons.

* No precipitation in the forecast. Afternoon cumulus buildups expected across northern California and East Side through Thursday...stray shower possible.

* Temperatures trend warmer Friday into the weekend, peaking around 5 degrees above normal.

* Sunday into early next week - pattern bears watching for potential thunderstorms and/or days where gusty winds combined with low RH could result in critical fire weather conditions.

A broad trough will remain over the region through at least Thursday, possibly into early Friday. Friday will be a transition day as strong high pressure over the eastern CONUS weakens and begins expanding westward. Heigheights will build over the area on Friday as high pressure strengthens and establishes over the Desert SW through the weekend. Meanwhile, weak low pressure waves will continue to move into British Columbia, leaving the area under southwest flow Sunday into early next week.

As broad troughing remains over the region through Thursday, the forecast will largely be a rinse/repeat scenario each day. Onshore flow will bring the return of stratus cover to areas west of the Cascades each night/morning, with clouds giving way to sun in the afternoons. High temperatures will hover around 5 to 10 degrees below normal, equating to upper 70s/low-mid 80s through Thursday. Expect some enhanced northwest breezes in the afternoons with gusts 20 to 25 mph. Overnight lows tonight could be chilly again, especially across northern Klamath/Lake Counties/Christmas Valley/Chemult region, and there could be patchy areas of frost where winds calm down overnight. Low temperatures will trend warmer for Thursday morning onward.

No precipitation is in the forecast, but there is enough upper level moisture and weak instability for some cumulus buildups to be possible across northern California and east of the Cascades in the afternoons. A stray shower isn't out of the question, but overall, we aren't seeing any strong signals for showers/thunderstorms through the week and into the weekend.

The pattern transitions on Friday as heigheights build over the region. We don't expect impactful weather through the 4th of July weekend. Temperatures will trend warmer on Friday, actually reaching values typical for this time of year -- low-upper 80s. As high pressure expands westward, and establishes itself over the dessert SW by Monday, we'll see an uptick trend in high temperatures. Temperatures will peak around 5 degrees above normal (upper 80s East /low 90s West), so we don't expect any heat related impacts into early next week and we should get through most of the Holiday weekend with fairly benign weather. With southwest flow over the region and high pressure in the dessert southwest, we'll need to monitor the pattern for any days where thunderstorms could be possible. Currently it looks like the soonest that could be would be Sunday into early next week as some guidance shows the remnants of some tropical moisture getting swept into the mid-lattitudes. At this time, it looks like that moisture stays far enough south to not be a concern for our area, but it is a pattern worth watching for any changes. Additionally, with weak troughs passing through to the north, we'll need to monitor for any days where gusty winds could line up with low daytime RHs and result in critical fire weather concerns. So just to summarize, at this point, there aren't any days we could point to in particular where impactful weather is expected, but we will be heading into a pattern early next week that bears watching for potentially impactful weather. Stay tuned. /BR-y
