| Area Forecast Discussion National Weather Service Medford OR 250pm PDT Monday Oct 18 2021 Satellite imagery depicts a mix of clouds and sun across most areas this afternoon, with more sun east of the Cascades and more clouds west of the Cascades. Quiet conditions will continue.nue through the night. On Tuesday an uncommonly strong October front will approach the forecast area, and south winds will become gusty, in the Shasta Valley first, then the coast, Rogue Valley, and areas east of the Cascades. We've issued Wind Advisories for the Shasta Valley and portions of the Rogue Valley, and portion of the East Side. We're confident these areas will see wind gusts to 45mph. At the coast, there's potential for a band of strong winds to impinge upon the coast, especially if the GFS model solution comes to fruition with low pressure deepening and moving towards the coast. Therefore, we have a High Wind Watch out for portions of the coast, generally from Cape Blanco south to Pistol River, including Gold Beach and Port Orford. Rain reaches the coast Tuesday evening and spreads inland. Due to the strong southerly flow, we expect the coast and Siskiyou County to see the brunt of the precipitation. We lowered snow levels down to around 4300 feet in the Mount Shasta area because of expected heavy precipitation there, but we think any snow impacts will be limited to areas above 5000 feet, based on the early season nature of this system and expected road temperatures. We'll keep an eye on this for any potential winter weather impacts to the Snowmans Summit area on Highway 89. Many valley areas, including the Rogue Valley, will see a lot of downsloping and drying under this wind regime, and rain totals here will be much less than high terrain areas. Conditions will dry out late Wednesday into Thursday morning, though continued moderate southerly wind flow will keep precipitation chances going in the Mount Shasta area. South winds will continue.nue in many areas Thursday, and it's likely we'll have additional wind hazards in places like the Shasta and Rogue Valleys. A deep low well off the coast will be weakening some Thursday, and the trajectory of this low will likely prevent high winds from affecting the coast Thursday, but this another area we'll be monitoring. The moisture with the front that arrives late Thursday into Friday morning has IVT values around 750 near the coast, placing it in the moderate- strong category in terms of how much moisture is being pushed into the forecast area along the front. We've increased forecast rain totals in the Brookings area Thursday evening and overnight to account for this strong onshore wind and high moisture content. Snow levels with this second system will be very high, peaking around 10000 feet before dropping Friday behind the front. The regime will likely shift to westerly-flow type systems over the weekend, and snow levels will begin to lower. Those areas that see little rainfall during the first southerly flow systems will begin to see more precipitation over the weekend and into early next week. There's additional potential for wind impacts too, as some models hint at some deep low pressure development off the coast. In short, the active, wet weather will continue.nue into early next week. Keene Marine Updated 230pm PDT Monday, 18 October 2021...Moderate northwest swell will build through this afternoon. A peak of around 9 ft at 12 seconds is expected, just shy of Small Craft Advisory criteria. Seas diminish tonight, but southerly winds will increase late tonight and early Tuesday morning ahead of a very strong cold front. Gales are expected Tuesday into Tuesday night with seas becoming very high and very steep and hazardous. Some storm force wind gusts are possible beyond 5 nm from shore at peak intensity Tuesday night. Seas are forecast to peak at 18 to 23 ft on Tuesday night. After this system moves through, seas remain chaotic with southerly fresh swell moving through the waters mixed with a relatively high 10 foot westerly swell. Another storm is expected to move into the waters around the Thursday time period. At this point, the winds are not expected to be as high, although gale force winds are possible later this weekend. -Smith NOAA Medford OR Office: Watches - Warnings - Advisories OR...Wind Advisory from 9pm Tuesday to 2pm PDT Wednesday for ORZ030-031.
