Area Forecast Discussion National Weather Service Medford OR 300 AM PST Tue Dec 10 2019
DISCUSSION. 10/00Z NAM/GFS/EC in.
Lots of low clouds and fog over the valleys this morning . and higher clouds ahead of an incoming front are overspreading the area.
The northern hemispheric pattern shows a wave number of 4 to 5 around the globe, which usually is a progressive pattern. That is the case here, even though there is a very high amplitude ridge just inland from the west coast at this time.
That ridge will move out very slowly to the east, but it will break down quite a bit over the next day or two. The upstream long wave trough will send short waves toward the west coast, the first of which will move onshore this evening. This wave will support a fairly wet front that will move onshore this afternoon. Precipitation will be significant, but not excessive, so no flood threats are anticipated. Snow levels will be high, generally 5000 to 6000 feet, so it will remain above the major passes. Post-frontal showers will persist into Wednesday, with only light activity expected during the day Wednesday.
More waves will follow. The flow aloft will break down to a brisk quasi-zonal pattern by Wednesday night. This pattern usually supports weak quick-moving systems moving onshore in rapid succession. The next front will move in Wednesday night, and Wednesday night and Thursday looks to be a very wet day over the Medford CWA, especially in the Coast Range. Rivers will rise quite a bit, but given the antecedent low stage levels, they should remain well below flood stage. Some small stream flooding may occur though. Snow levels will still be high, rising above 6000 feet during the heaviest precipitation.
Flat ridging will develop Thursday into Thursday night, forcing the storm track slightly farther north, but there will still be significant activity over the Medford CWA. Another front will move in Friday. This one will not be nearly as wet as the Thursday system.
The ridge will break down Friday, and a weak trough will move onshore Saturday. This trough will support yet another front. Snow levels will be down to the pass levels with this system, and there may be some impacts on area highways.
A stronger ridge will build into the west coast Sunday. The EC and the GFS differ on the strength of this ridge, but both models suggest that any precipitation Sunday into Monday will be light.
The ridge axis will break to the east of the area Monday, and the next upstream trough, which looks to be a fairly strong one, will move onshore next Tuesday. The front with it doesn't look as impressive, but it will keep the wet and occasionally windy pattern going.
AVIATION. For the 10/06Z TAFs . A mix of IFR/LIFR should continue in Illinois, Scott and Shasta Valleys as well as some of the valleys east of the Cascades, including near Klamath Falls. VFR/MVFR in North Bend, Roseburg and Medford expected to become IFR/LIFR stratus/fog overnight into the morning. A frontal system will arrive at the coast by mid-morning with some light precipitation moving in west of the Cascades in the afternoon/evening, then shifting east of the Cascades at night. This will produce areas of MVFR and terrain obscuration. -Miles
MARINE. Updated 130 AM PST Tuesday, 10 December 2019 . A weak cold front will move through the waters today. This will bring an increase in south winds with seas becoming steep early this morning. Latest data suggests winds won't quite reach advisory criteria, but the combination of gusty south winds and west swell will create conditions that are hazardous to small craft. This front will be the start of a series of disturbances that will continue through the week and into the weekend.
South winds increase again Wednesday as a stronger front moves through the waters. South winds with this front will certainly reach advisory criteria and may even approach gales at times Wednesday afternoon and evening. In addition, a high and steep, long period west swell builds late Wednesday, lingering into Friday. Seas of 16 to 17 feet at 17 seconds are expected and will likely impact bar crossings and crab pots. The strongest winds during the forecast period are expected Wednesday, and the heavy long period west swell will gradually diminish late Friday into the weekend. However, the weather will remain active with periods of moderate to heavy rain Wednesday through at least Saturday. BR-y/Keene

I have no idea of they are useful or accurate, I leave that to the reader. 2) Articles others have written and submitted.

These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
