PZZ300 843 Am Pdt Tue Jun 25 2024

Synopsis for the southern oregon coastal waters - The thermal trough pattern gets disrupted today as an upper level trough approaches the region. Steep seas this morning will improve by the afternoon, with sub-advisory conditions expected through at least Thursday. A weak front will push through the region later today into Wednesday, bringing a deep layer of low clouds and a chance of showers Wednesday night. A return of the thermal trough pattern is expected Thursday into Friday night, with steep seas possible south of cape blanco. Another front and deep marine layer are likely to disrupt the pattern, with improved conditions for the weekend.

Area Forecast Discussion National Weather Service Medford OR 318 AM PDT Tue Jun 25 2024

DISCUSSION
The weather pattern over the next 7 days will be one that is fairly typical for early summer with upper ridging giving way to troughs and/or mostly dry fronts as the northern branch of the upper jet seasonally edges back toward the north. This will keep the majority of the action well to our north, but the weather forecast isn`t trivial with a whole host of subtle, but noticeable day to day changes.

Right now, an upper ridge axis exists near the Cascades. This will likely bring the hottest day of the stretch to most of the area today with highs of 90-95F in populated inland areas, perhaps a degree or two higher/lower depending on location. A minor marine intrusion is resulting in some stratus near the Coos and southern Curry coasts, as well as the Coquille Valley this morning, but these clouds should tend to dissipate through the morning/early afternoon; it will be cooler there with highs generally 60-70F.
The remainder of the area will start off sunny today with the usual afternoon/evening NW breezes west of the Cascades and increasingly gusty WSW breezes over the east side. Satellite imagery is showing some mid-high level moisture advancing north- northeastward from California and just offshore this morning. Some mid-high level clouds will arrive from the south this morning, but especially this afternoon and tonight, primarily in NorCal and from about the Cascades eastward.

Models are showing an area of elevated instability (~50-100 J/KG in the 600-300mb layer) as this moisture axis swings through tonight into the wee hours of Wednesday morning. This is likely to generate some elevated showers/virga given a very dry sub-cloud layer. A few sprinkles could reach the ground. While there isn`t much forcing for convection, and model ensemble probabilities of thunder are generally 15% or less, there have been isolated lightning flashes off the California coast this morning. So, it certainly wouldn`t be surprising to see a flash or two overnight, especially from around the Modoc northeast to southern Lake County. The overall forecaster confidence in lightning is low, but the official forecast includes this low probability of occurrence for those areas tonight. We expect this moisture axis to shift to the north and east away from the area on Wednesday as another upper trough approaches from the west. The implication of the nocturnal lightning is that if it occurs and fire starts result, a period of dry and windy conditions will lead to critical fire weather conditions east of the Cascades during Wednesday afternoon/evening. And, this would provide the weather variable to support any new fires to spread rapidly.

Farther west, however, Wednesday will begin a period of cooling with high temperatures about 10F lower than today. This will continue Wednesday night into Thursday morning as the cool, upper trough pushes inland through the PacNW. During that time, there is a chance (20-30%) of light rain showers along the Coos/Douglas/Curry Coasts and into northern Douglas County, but most everywhere else will remain dry. Temperatures inland on Thursday will be about 5-8F below normal for highs.

The cool down will be brief, however, as short wave ridging on Friday brings dry, sunny weather and temperatures back to near or slightly above normal levels. The next upper trough offshore will approach the coast Friday night into Saturday and this will lead to an uptick in afternoon/evening breezes again, especially over the east side. Shower chances increase (20-40% chance) along the coast and into Douglas County Saturday night into Sunday as the upper trough moves onshore yielding yet another cool down for inland sections. There is also a chance of showers in portions of northern Klamath and Lake counties (15-25% chance) Sunday afternoon.

Aside from late night and morning stratus along the coast, dry weather will prevail early next week. -Spilde

AVIATION
(25/12Z TAFs)...IFR conditions in marine stratus are expected to expand in coastal areas overnight into early Tuesday morning, especially north of Cape Blanco and south of Brookings.
These low clouds are expected to dissipate after sunrise, with VFR by 18Z. A thicker, more extensive band of IFR stratus is expected along the coast into the Coquille and lower Umpqua valleys late this evening into Wednesday morning.

Otherwise, VFR conditions are expected to prevail through the TAF period for inland locations, with breezy afternoon and evening westerly winds. Winds will be strongest east of the Cascades with gusts up to 25 kt. /DW



MARINE
Updated 200 AM Tuesday, June 25, 2024...The thermal trough continues with steep seas for much of the waters south of Cape Blanco into this morning. The approach of another front then disrupts the pattern with improving conditions Tuesday into early Thursday.

The front is expected to provide a deep layer of low clouds and a chance of showers Wednesday night. A return of the thermal trough pattern is expected Thursday into Friday night, with steep seas possible south of Cape Blanco. Another front and deep marine layer are likely to disrupt the pattern, with improved conditions for the weekend.
/DW



FIRE WEATHER
Breezy WSW winds (15-25 mph with gusts to 35 mph)
are expected to develop again this afternoon and evening, especially for areas east of the Cascades. This, in combination with another day of minimum relative humidity in the 10-15% range, will create critical fire weather conditions in portions of the Fremont/Winema and Modoc National Forests. A Red Flag Warning is in effect from noon until 8 pm today for that. Meanwhile, mid and upper level moisture will arrive from the south today. This could generate some elevated showers/virga tonight, especially from the Cascades eastward. Models are showing some elevated instability in concert with this moisture axis, but ensemble model lightning probabilities are low (15% chance or less). We have seen a few lightning flashes off the coast of California this morning associated with this moisture/instability, so it wouldn`t be surprising to see a flash or two tonight. The best chance for this to occur will be in eastern Modoc northeast to southern Lake County. While forecaster confidence in lightning is low, the implication of the nocturnal lightning is that if it does occur and fire starts result, we are still expecting a period of dry and windy conditions Wednesday afternoon/evening. This will lead to critical fire weather conditions east of the Cascades and any fires that do start would spread rapidly. As such, we have a Fire Weather Watch out for the strong, gusty winds and low RH expected Wednesday afternoon and evening for FWZs 624/625 in Oregon and FWZ285 in California. Wind gusts could be up to 40 mph. There is also a chance that winds are strong enough in the Scott Valley along with low humidity to bring a few hours of critical or near- critical conditions there. Duration may not be quite long enough, however. After that, things should calm down a bit fire weather- wise Wednesday night into Thursday with a cool down, better humidity recoveries and less wind. It`ll be dry and warmer Friday, but still not too bad wind-wise. The next upper trough will bring increasing afternoon/evening breezes Saturday/Sunday.
