What the forecast actually says — NWS Area Forecast Discussions, decoded into plain English.
Plaincast decodes the National Weather Service's Area Forecast Discussion — the real forecast, written 3 to 4 times a day by the meteorologist on shift — into plain English. The discussion is where a forecaster explains their reasoning: which models disagree, what they are watching, and how confident they are. Below is the current edition for Medford, with its shorthand expanded. The full experience — an AI plain-English summary beside the annotated original — loads with JavaScript, and every one of the 68 forecast offices has its own edition.
High impact marine weather today and lasting through the weekend
Inland, low to moderate impacts from strong winds and rainfall; minimal impacts from snow occuring mainly above 5000 feet
Active weather likely to continue through the weekend and early next week
Low pressure, centered near 47N and 134W, or about 550 miles west of Seattle, WA, is sending a strong cold front through our coastal waters early this morning. Strong, gusty southerly winds are surfacing in advance of this front with many areas reporting wind gusts in the 40-65 mph range. Montague, in the Shasta Valley, just reported a wind gust of 66 mph and it's been regularly blowing at 35-45 mph in Klamath Falls. SE winds surfaced here at the airport around 2 am with a peak gust so far of 39 mph. Winds are picking up at the coast right now as well and expect the strongest winds there in the next few hours until mid- morning. Meanwhile, where the inversion has been strong, Roseburg is attempting to fog in. This won't last though since the front is moving onshore and the front will stir things up there as well. Wind advisories and high wind warnings are up through the morning along the coast and the Rogue Valleys and into this afternoon for the Shasta Valley and East Side.
Periods of moderate to heavy rainfall will accompany the front. Expecting 1-3" along the coast, highest in the coast ranges and in portions of southern/western Siskiyou County; 0.50-1.00" over the interior from the Cascades west, but perhaps slightly lower in downslope areas (western valleys) where amounts might only be 0.25-0.50". Same goes for most east side areas, except less than 0.25" over the east side deserts (east of Winter Rim). Rain from the front should be largely beneficial, though ponding may occur briefly in heavier rainfall. Try to clear leaves away from storm drains as this could be a source for localized nuisance ponding/flooding. Post-frontal showers will persist along and west of the Cascades this afternoon and tonight, especially though over the coastal waters and along the coast/coast range mountains, where there can also be isolated thunderstorms. After the front moves through, precipitation should largely end east of the Cascades.
We're not anticipating much in the way of winter impacts from this storm, though higher elevations above 5500 feet could see up to a few inches of snow (Crater Lake NP and Mt Ashland/Shasta Ski areas), to name a few. Locally, snow levels could drop as low as 5000 feet tonight with some slippery roads possible around Diamond Lake or Willamette Pass.
We'll get a brief break Saturday, but another front will move in Saturday night into Sunday. This will bring another round of gusty south winds and beneficial rainfall. Right now, the strongest winds look to occur over the coastal waters and the immediate coast with perhaps some advisory level winds over the interior. We'll take a look at potential hazards in more depth today. Things look like they'll settle down a bit on Monday/Tuesday before the next front moves in Tuesday night into Wednesday. -Spilde
