Updated AVIATION discussion

DISCUSSION
The main update this morning was to issue a Winter Weather Advisory for elevations above 5000 feet in the southern Oregon Cascades from noon today through 2 PM Friday afternoon.
Snow levels will begin at 6000 to 6500 feet this afternoon into this evening, then diminish to 5000 feet accompanying the highest snowfall rates from around 2 AM Friday into Friday afternoon.
Amounts of 5 to 15 inches are forecast with highest amounts for the back country. Recent warmth is sure to limit amounts on roadways, but at the very least those traveling around Crater Lake, Diamond Lake, and Willamette Pass should be prepared for reduced visibilities. The highest peaks of the Siskiyou Mountains, Warner Mountains, and Siskiyou County can also expect to receive measureable accumulations.

This is quite a shift in the weather given our most recent conditions resembling early summer. Elsewhere, the cold frontal passage and post-frontal showers is about to begin rain at the coast, and will spread across the west side during this morning.
With a westerly flow and the downslope influence of the Cascades, precipitation amounts and coverage accompanying the front will be substantially less east of the Cascades during the afternoon.

As is often the case in our region, higher amounts will accompany the passage of the axis of the trailing, cold, upper level low early Friday into Friday afternoon.

Lingering showers and snow showers will gradually diminish through all of Friday evening. A brief break between systems follows late Friday night into Saturday morning.

The next, weaker front will bring (again) mainly west side precipitation Saturday afternoon through Saturday evening.

Late Saturday night through all of Sunday into Monday morning, a couple of additional, weak fronts will be focused north of our area. But, they will bring scattered light showers to the coast and Douglas County.

Monday afternoon through Tuesday, possibly into Tuesday evening, is most likely to be a break in the action, allowing high temperatures on Tuesday to rebound to slightly above normal...for the first time since yesterday.

Another vigorous (for this time of the year) cold front is likely to bring precipitation across the region, arriving at the coast late Tuesday night then spreading inland Wednesday through Wednesday night. The trailing upper trough is then anticipated to bring showers and lower snow levels (around 4000 to 5000 feet)
Thursday/Day 7 into Friday night/Day 8.

AVIATION
25/12Z TAFs...A combination of stratus ceilings and an approaching cold front are bringing lower flight levels to parts of northern California and southern Oregon. Areas of MVFR and IFR levels under low ceilings are present along the Oregon coast and in southern Siskiyou and Modoc counties. Light rainfall over North Bend indicates an arriving front, which could help to mix out inland stratus early this morning.

Later this morning, MVFR or lower levels will continue along the Oregon coast with generally VFR levels under high clouds for inland areas. However, scattered showers will be possible later from this morning through the TAF period. Showers may lower ceilings and visibility as well as obscure terrain. Gusty winds will increase along the Oregon coast and areas east of the Cascades this afternoon, with winds calming later tonight. -TAD

MARINE
Updated 215 AM Thursday, April 25, 2024...Seas remain calm ahead of a weak front that will arrive this morning. Guidance suggests enough fresh swell to bring steep seas to all waters will precede the front, with elevated southerly winds arriving later this morning and continuing into the evening. There will be 70-100% chances of widespread showers over marine waters through Friday evening, but thunderstorms are not expected. An existing Small Craft Advisory in place from today at 5 AM through Saturday at 2 AM has been expanded to cover all marine waters.

There are some small chances of more chaotic conditions during the Small Craft hazard. The combination of fresh swell and gusty winds as the front approaches may build occasional isolated areas of very steep seas in waters north of Cape Blanco through Friday morning.
Additionally, wind gusts of 30 to 35 kts are forecast north of Cape Blanco through this evening. Probabilistic guidance suggests a 10% chances of wind gusts nearing gale strength over inner waters north of Bandon this afternoon. There is not enough confidence in a steady area or exact timing for these higher level of hazards, but the possibility is worth acknowledging.

Seas are expected to calm during the day Saturday before active weather returns on Sunday and looks to continue into next week as a series of fronts and systems affect the area. Longer term guidance suggests only occasional 10-40% chances of total seas exceeding 9 feet through next week, with the 40% chances associated with a low pressure system settling near the Canadian coast on Tuesday. Future further steep seas look likely at times during next week, but more chaotic conditions are not expected. -TAD
