Marine Weather and Tide Forecast for Lakeside, OR

AVIATION
26/00Z TAFs...Widespread showers mainly east of the I-5 corridor with isolated thunderstorms will gradually move from east to west this afternoon, gradually pivoting and moving from northeast to southwest this evening and overnight. This is resulting in some low end VFR conditions mixed with MVFR and widespread terrain obscurations. MVFR conditions are likely to become more widespread this evening and overnight as shower activity continues. The thunderstorm potential should wane after sunset, and in the meantime an isolated thunderstorm could impact the Medford and Klamath Falls terminals. Will monitor and update as needed.

For areas west of the I-5 corridor and along the coast, a mix of MVFR/IFR conditions prevail. Showers and isolated thunderstorms should remain east of these areas, but some light rain will be possible in the Umpqua Basin and Illinois Valley. IFR/LIFR conditions are expected along the coast and into the Umpqua Basin overnight. Conditions should improve to at least MVFR Saturday morning. /BR-y

PREV DISCUSSION
/Issued 239 PM PDT Fri Apr 25 2025/

DISCUSSION...Showers are spreading across Klamath and Lake counties. there are also a few cells developing near the California/Oregon border with a small thunderstorm at the Klamath/Jackson County border. Temperatures are facing a 5-10 degree cooldown compared to yesterday in valleys this afternoon with temperatures only reaching the low/mid-60s at the warmest.

The upper low is starting to move into the west coast to the south into California. The shower activity will continue moving in from the south today with more of it reaching areas east of the Cascades.
These will become more widespread tonight as it continues through portions of Southern Oregon and into areas west of the Cascades.
Later this afternoon there is a 20-30% probability to see some thunder for parts of Jackson and Klamath counties. The best chance for thunder will be in eastern Lake County with the HRRR proposing a 30-40% probability this evening.

Saturday afternoon convection will also be focused on portions of Lake County, so there is a 15-25% probability added for that area with forecast CAPEs 100-250 J/kg. Snow levels will be falling to around 6,000-6,500 feet Saturday afternoon, meaning that higher elevations including Crater Lake and the Warner Mountains in Modoc County will have some snow. Otherwise, later Saturday afternoon will have rain showers that focus on areas in Siskiyou County and up through Klamath and Lake counties.

Ensembles are favoring ridging to set into the PNW early next week, and dry conditions are favored through the first half of the work week. A warm up will be felt with highs back to normal/slightly above normal by Monday. The warming will continue through the week with current probabilities for 80 degrees in west side valleys reaching 70-90% next Thursday. -Hermansen
