8/26/2020 The 7 day forecast is taking about 5 seconds to load but it will eventually load. NOAA is still working on it. 8/18/2020 NOAA continues to have trouble. Wind guest will occasionally be left off graphs. I am working with NOAA to resolve the issue. 12/16/2019 NOAA is having trouble with requests that include wind gusts. I am posting graphs without wind gusts until it gets fixed. 10/9/2019 Updated the Marine Zones. 9/4/2019 Fixed the weather maps due to NOAA moving them. 7/25/2019 New feature in the Airports section gives a link to 5 minute updates for data reports. |

Synopsis for the southern oregon coastal waters..South to southwest winds are increasing today ahead of low pressure that will move through the waters from north to south tonight. Small craft advisory conditions will impact the area starting Friday morning with north winds and seas increasing behind the low pressure. Warning level very steep seas will follow by Friday afternoon due to combined gusty north winds and shorter period northwest swell. High pressure builds in Saturday with continued north winds, followed by a strong cold front on Sunday.

Updated AVIATION Section
SHORT TERM. Beginning tonight, a more active pattern arrives in southern Oregon and northern California. Each system is expected to be more potent than the previous. So, beginning tonight, a weak front will move southward into our area. Dry air remains well entrained into this first low, so precipitation amounts will be limited. The big thing is that snow levels will be relatively low since we are already somewhat cold. The best chance for snow will be above 3000 feet, but as we move into showers with the dry air entrained, any spots without clouds could cool down to freezing (away from the coast), and then when a shower moves over the area, some snow will be possible, including a few flurries on the valley floors tonight. Showers will continue on Friday and then dissipate into Friday evening.
Conditions will dry out on Saturday, but will remain chilly across the area. Then, the next system arrives on Sunday and will linger into Monday. This will be the best chance for valley snows so far this year. Snow levels will largely be around 2000 feet, through the early parts of the event, so the low passes may see some impacts, including Hayes Hill, Siskiyou and Sexton Summits. But dry air could also produce some ice loading with evaporative cooling in the west side valleys, so we could easily see snow early on with this event for the valley floors, changing to rain, then back to snow behind the front in the lingering showers on Monday morning. Right now, there is a 60% chance for this scenario, while there is a 40% chance of snow occurring during the entire event everywhere except for the coast. That being said, even if we had snow the entire time, I do not expect accumulations during the day. Overall amounts are not expected to be extremely high, even in the mountains; but valley snow is always impactful.
Things start to dry out Monday night before the next system arriving on Tuesday night. But more information can be found in the long term discussion.
LONG TERM. Jan 26th through Jan 28th. As we head into Tuesday next week the system that moves in comes in unlike the systems that precede it through the weekend and very early next week. Previous systems ahead of this one were in northwest flow at 700 mb, while the one moving in on Tuesday sees the more usual southerly 700 mb flow. However, where the usual strong southerly flow brings warmer temperatures and higher snow levels, except for where the precipitation rates are very high like the Mt. Shasta region, cold air will be wrapped around the upper trough, bringing continued cold temperatures at ridge levels and higher.
As the front moves in Tuesday afternoon 850 mb temperatures are in the -3 to -5C range, which is very unusually cold for this type of strong southerly flow system. This will continue lower snow levels with this system, but with the stronger southerly flow orographic effects will be more dominant, with the bulk of the precipitation in Northern California, especially in the Salmon and Scott Mountains and the Mt Shasta Region, which could see possible amounts of near a foot or more. Heavy precipitation rates are possible on the Slater fire and the Red Salmon Complex Tuesday, but debris flow problems are not expected as the bulk of the precipitation will be as snow with snow levels of 1500 to 2000 ft during this time.
Previous EC showed very little precipitation when I came on shift, but the latest run came very much in line with with the GFS and confidence has increased to Moderate, say 40-50%, in these areas and out of our forecast area in the northern Sierras for this system. An active pattern with snow levels occasionally a bit higher remains into the end of next week. Sven
AVIATION. For the 22/00Z TAFs . VFR will prevail for most areas this evening and it will remain that way overnight over the east side. However, low pressure offshore will move southward tonight resulting in rain with MVFR ceilings along the coast. MVFR ceilings with areas of higher terrain obscured and mostly light precipitation will move inland on Friday. -Spilde
MARINE. Updated 230 PM PST Thursday, 21 Jan 2021 . South to southwest winds are increasing today ahead of low pressure that will move through the waters from north to south tonight. Small Craft Advisory conditions will impact the area starting Friday morning with north winds and seas increasing behind the low pressure. Warning level very steep seas will follow by Friday afternoon due to combined gusty north winds and shorter period northwest swell. High pressure builds in Saturday with continued north winds, followed by a strong cold front on Sunday. A high and steep northwest swell is expected behind the cold front Sunday afternoon into Monday. Keene
