974 FXUS66 KMFR 240334 AFDMFR Area Forecast Discussion National Weather Service Medford OR 834 PM PDT Mon Sep 23 2024 .DISCUSSION...Adjustments were made to the sky cover to this evening and tonight to better match the latest visible image. Adjustments were also made to the weather to confine the haze and patchy smoke to northeast Lake County as the current smoke models suggest this is where patchy smoke and haze will be at. The rest of the forecast is still on track. Dry weather will continue into Wednesday morning with afternoon temperatures peaking out to well above normal values Tuesday for the interior westside valleys as the thermal trough moves inland. Meanwhile weak onshore flow will result in cooler afternoon temperatures at Brookings. Speaking of which, offshore flow is still keeping Brookings toasty with a temperature of 89 degrees as of this writing. Pretty impressive for this time of the year and at this time in the evening. Cooling is likely on Wednesday as a weak front approaches the coast. -Petrucelli && .AVIATION...24/00Z TAFS...VFR conditions will prevail across the region through the TAF period with patchy high level clouds streaming through the area. LIFR/IFR cigs/vis are likely to return to the coast north of Cape Blanco between 03z-06z, then around Brookings for a brief period around 12-15z. /BR-y && .MARINE...Updated 800 PM Monday, September 23, 2024...The thermal trough will gradually expand northward tonight, then weaken Tuesday morning. Steep seas will persist through tonight, then conditions will improve with weakening winds as the day progresses on Tuesday. Conditions hazardous to small craft are expected through Tuesday morning for areas south of Bandon. Seas will transition to swell dominated Tuesday as the upper level pattern transitions and multiple swell trains pass through the area waters during the week. In general, these northwest swell trains will range from 7 to 9 ft at 12 to 14 seconds, possibly reaching up to 10 to 11 ft on Friday. A front will pass through the area on Wednesday and again on Friday. These fronts will weaken as they approach the region, limiting the concern for strong south winds ahead of the fronts. Some light precipitation will be possible, with the best chances being north of Cape Blanco and with the Wednesday front. /BR-y && .MFR WATCHES/WARNINGS/ADVISORIES... OR...CA...None. PACIFIC COASTAL WATERS...Small Craft Advisory until 11 AM PDT Tuesday for PZZ356-370-376. && $$
