982 FXUS66 KMFR 191547 AFDMFR Area Forecast Discussion National Weather Service Medford OR 847 AM PDT Thu Sep 19 2024 .DISCUSSION...Satellite image shows marine stratus along the coast north of Cape Blanco and from about Gold Beach south, although Brookings has just cleared out withing the last hour. Elsewhere it`s clear and it will remain that way through this afternoon. However a few high clouds will move in from the northwest this afternoon. The marine stratus will burn off during the morning with clear skies by late morning. The forecast is on track and no updates are needed. A quick look at some of the guidance is pointing towards a rather quiet weather pattern for the next 10 days with continued dry weather. -Petrucelli && .AVIATION...19/12Z TAFS...IFR/LIFR are impacting coastal locations this morning, from Cape Blanco north, and south of Gold Beach. Expect the stratus/fog to break up around 18z, then gusty north winds (gusts up to 30 kts) will develop at North Bend this afternoon. IFR ceilings will return to similar areas tonight, but probably not as widespread as it was earlier this morning. Inland, areas of MVFR ceilings in the Umpqua Basin, including Roseburg could persist until 19z, then VFR will return this afternoon and continue through most of tonight with MVFR ceilings returning between 10-11z. Elsewhere, VFR conditions will continue through the TAF period. -Petrucelli && .MARINE...Updated 830 AM Thursday, September 19, 2024...A thermal trough has brought gusty northerly winds, building steep seas in waters south of Cape Blanco. Steep seas will spread to waters north of Cape Blanco later this morning, with very steep and hazardous seas expected south of Pistol River through Friday afternoon. Periods of very steep seas may be possible as far north as Gold Beach into Friday evening. Occasional gale gusts will be possible on the afternoon and evening as well. The thermal trough remains in place into early next week, then it will weaken with winds and seas easing towards Tuesday evening. A Hazardous Seas Warning is in place for waters south of Gold Beach and beyond 5 nm from shore, and a Small Craft Advisory will cover all other waters. Currently these hazards are in place through Friday at 5 PM, but are likely to extend through the weekend. -Hermansen/Petrucelli && .MFR WATCHES/WARNINGS/ADVISORIES... OR...CA...None.
