Area Discussion for - Eureka, CA
(on/off) Help NOTE: mouseover dotted underlined text for definition| Fxus66 keka 231108 afdeka area forecast discussion national weather service eureka ca 408 am pdt Fri aug 23 2019 Synopsis A gradual warming trend is expected today through the middle of next week, with triple digit heat expected across many interior valley areas expected by Monday. Coastal areas are also expected to see above normal temperatures, again especially early next week. Little to no precipitation is expected. Discussion Aside from limited patches near the klamath and eel river deltas, marine stratus clouds are largely absent from the north coast as of 4 a.M. Friday. This is a significant departure from the prior morning, when widespread low stratus, fog, and even some drizzle lingered well into the late morning. The root cause is likely the rapid warming of temperatures in the lower atmosphere, which is clearly being observed by the atmospheric profiler at the arcata eureka airport. While stratus south of the bay area does appear to be expanding and gradually spreading northward, and high resolution models do indicate that at least some redeveloping stratus is possible during the day, it seems most likely that coastal areas will remain largely clear of clouds and fog for most of the daylight hours Friday. However, a gradually expanding ribbon of southerly flow along the immediate coast will likely bring stratus back into some coastal areas late this evening, at least as far north as CAPE mendocino, followed by a reinforcing and expansive stratus shield from the west early Saturday morning. Shallow stratus and fog will then likely follow a typical pattern of moving inland overnight and lingering into the morning hours before diminishing during the afternoon Saturday and possibly Sunday, before gradually eroding Monday and Tuesday. Sunny skies will continue across interior areas through at least Tuesday. Meanwhile, gradually building high pressure aloft throughout the state is expected to drive a gradual warming trend today through Wednesday, with the peak of the heat expected Monday through Wednesday. Afternoon interior valley temperatures are expected to climb from the mid to upper 90s Friday through Sunday, to between 100 and 105 degrees Monday through Wednesday... And perhaps locally higher in a few of the warmer valleys. As a result, the threat of light to moderate heat related impacts appears possible, particularly Monday through Wednesday. The bulk of the heat impacts are likely to be experienced across interior valley locations during the afternoons, particularly in trinity county, but even coastal areas are likely to observe above normal temperatures by early next week. Still, low humidity and clear skies will promote radiational cooling and cool air drainage in interior valleys, and low temperatures are likely to fall into the low 60s and even upper 50s overnight as a result. This will help to mitigate heat impacts locally, but perhaps not quite as well in areas to our east and northeast in the central valley and southern oregon. Between Tuesday and Thursday, a weak upper level impulse is expected to move through the region from the southwest. This wave will likely drive lower surface pressure and light southerly winds across the waters. While it's possible that this could eventually result in another surge of very shallow marine stratus from the south, this will also likely lead to above normal coastal temperatures Monday through Wednesday. Meanwhile, while atmospheric moisture content appears to be meager, a small potential for isolated and mostly dry thunderstorms will continue to be monitored toward the middle of the week. Brc Aviation Offshore flow has kept the coast mostly clear this morning with only a few local patches of stratus as of 3:30 am. It is possible the coastal airports could briefly be impacted around |
sunrise, but this is looking less likely as the night progresses. Confidence is high that there will remain clear through the afternoon today. Northerly winds of 10 to 15 kt are possible this afternoon along the coast with light winds inland. Tonight winds at the coast are expected to turn southerly. This could bring some stratus north to at least CAPE mendocino and it may continue north Saturday morning. This will need to be monitored as it gets closer. Mkk Marine Northerly winds continue across much of the area this morning, although some areas very near the coast are seeing southerly winds. The winds have diminished slightly over the waters and the gale warning set to expire at 5am looks on track. Seas will also slowly diminish today and tonight. Will likely need to issue a hazardous seas warning for the northern outer waters once the gale expires. Tonight seas in the outer waters are expected to drop below 10 feet. For the weekend and into Monday winds and short period seas will remain moderate to fresh. This will keep the steep seas around 7 to 10 feet and small craft advisories will likely be needed. Closer to the coast local areas of southerly winds are expected. Most of these will be around 5 to 10 kt, but a few local areas of 10 kt are possible. These may not be captured in the coastal waters forecast, but will continue to highlight them in the discussion. A west to northwest swell around 3 feet at 12 seconds continues to move through the waters. This is expected to continue through the weekend. Early next week winds will continue to diminish, although models are now keeping northerlies in the outer waters through Monday. By mid- week models are trying to show a trough or upper level low moving into the area. The models are fairly confident that winds will be light, but are struggling with the position of the low and the direction of the surface winds. Mkk Fire weather A gradual warming trend is expected to unfold throughout the region between today and Wednesday, with the peak of the heat expected between Monday and Wednesday. Inland afternoon high temperatures are likely to climb from the mid to upper 90s late in the week and over the weekend, to between 100 and 105 degrees Monday through Wednesday. In addition to the increasing heat, humidity will also decrease, with low afternoon minimums expected and moderate to poor recoveries. Winds are not expected to be particularly strong on a large scale, and will be driven by typical daytime onshore and nighttime offshore fluctuations. Winds may become locally gusty on a smaller scale, most likely in areas where the terrain favors stronger upslope and upvalley wind development. Meanwhile, little to no precipitation is expected for the foreseeable future. However, while it remains unlikely in northwest california, a very low chance for isolated dry thunderstorms near the middle of next week is being monitored. Brc Eka watches warnings advisories Ca...

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. |
