PZZ300 238 Am Pdt Tue May 21 2024
Synopsis for the southern oregon coastal waters - Steep wind driven seas south of cape blanco are expected through this morning with some relief expected in the afternoon. Conditions will be less severe and borderline hazardous to small craft north of cape blanco. With the arrival of another front Wednesday, we may need to consider another small craft advisory for the waters. A break in hazardous conditions may come Thursday and potentially lasting through the weekend.

Area Forecast Discussion National Weather Service Medford OR 233 AM PDT Tue May 21 2024

DISCUSSION
Progressive NW flow aloft will bring another disturbance into the area tonight into Wednesday. The air mass preceding it is pretty dry, so many areas will eke out a pleasant spring day today. Most areas start out sunny, then we expect increasing amounts of mostly high/mid clouds this afternoon.
Afternoon temperatures will be mostly in the 70s for the valleys of the west side and in the 60s east of the Cascades. Clouds will lower in NW sections by late this afternoon and there is a 20-30% chance of showers. But, even there, odds favor it remaining dry through 5 pm.

As the upper trough/cold front moves onshore into the PacNW, precip chances increase tonight along the coast, near the Rogue- Umpqua Divide, over to the Cascades and even across Oregon sections of the East Side. Those chances are highest (generally 60-90%) in Coos/Douglas counties and near the Cascades, but drop off to almost nil in portions of NorCal. Rain amounts of 0.10 of an inch or less will be most common, but some reports of 0.25-0.50 of an inch may occur in the Cascades Mtns/Foothills. Models do show some light showers also moving across the Rogue Valley, but these will be isolated in nature. Best chance of a rain shower here is between 3 and 9 am. Snow levels should be high enough to preclude wintry impacts, though some wet snowflakes may mix in with the rain showers near the higher Cascades Wednesday morning.

The front and upper trough will shift to the east of the area Wednesday afternoon and precip chances will dwindle to almost nothing again, except for a 20% chance of showers lingering across the far north near Willamette Pass. Strong, gusty NW winds are expected in many areas since we expect very good vertical mixing and decent winds aloft (mid-level winds generally in the 35-45 kt range). Wind gusts of 35-44 mph will be common over the mountains and east of the Cascades (35-44 mph), but these winds should mostly be sub-advisory level (>=45 mph).

A short wave upper ridge/subsidence will move in Wednesday night into Thursday bringing clearing and colder conditions. Some fog will develop in the west side valleys, especially the Coquille and Umpqua Valleys. With the clear skies, patchy frost is possible in the typically colder valley spots (Illinois/Applegate/Scott and Shasta) and even some outlying areas of Medford/Ashland/Grants Pass. It'll be cold Thursday morning over the Cascades/East Side where lows will be in the 20s. Despite the cold start in many areas, it will turn out sunny and milder Thursday afternoon.

Friday will be much like today. Another upper level trough will move into the PacNW on NW flow. Most areas start out sunny, then we expect increasing amounts of mostly high/mid clouds during the afternoon. Clouds thicken in NW sections during the pm/eve, where there is about a 20-40% chance of showers. Shower chances remain mostly north of Highway 140 and Lake of the Woods in the Cascades with precip chances south and east of there generally 10% or less.
It'll be breezy to windy and cooler again on Saturday as the upper trough swings into eastern Washington/NE Oregon. High pressure builds in for Sunday and Monday, Memorial Day. With higher heights and a shift in the flow aloft to WSW, we should see a warm up back to above normal levels early next week. -Spilde



AVIATION
21/06Z TAFs...VFR conditions will continue through Tuesday afternoon. Guidance shows some low clouds moving along and just off the coast, north of Cape Blanco later tonight, but it's not expected to have an impact on flight conditions. Breezy winds are expected at the terminals Tuesday afternoon and early evening, but winds speeds should be less than they were earlier this afternoon.
MVFR and IFR ceilings and areas of MVFR visibilities are expected to develop along the coast north of Cape Blanco early Tuesday evening.
These conditions are expected to become widespread along the southern Oregon coast and into the Umpqua basin by late Tuesday evening. -CC



MARINE
Updated 230 AM Tuesday, May 21, 2024...Seas are anticipated to stay fairly consistent with current conditions through much of today with only small deviations. If anything, wind speeds are expected to diminish across the northern waters today bringing seas lower as well. However, areas south of Cape Blanco will likely experience small craft advisory conditions through at least parts of today. The current advisory goes until early this afternoon, but we may need an expansion and extension as the next front moves into the region. By Thursday, we may see a break in hazardous conditions over the waters through the weekend.
