Area Discussion for - Eureka, CA
(on/off) Help NOTE: mouseover dotted underlined text for definition| Fxus66 keka 191102 afdeka area forecast discussion national weather service eureka ca 402 am pdt Mon aug 19 2019 Synopsis Seasonable temperatures will occur across the interior through mid week. In addition, light showers will be possible during Wednesday over del norte county. After Wednesday, temperatures are forecast to warm across the interior. Discussion A weak trough located in the vicinity of the NRN ca coast will aid in maintaining seasonable temperatures across interior portions of the eka CWA today and tomorrow. Stratus will also be a common feature along the coast, with patchy drizzle possible Monday night as the marine layer deepens. Otherwise, multi-model guidance shows a progressive upper-level trough moving east across the nern pac and pac NW during Wednesday. As that occurs, a surface cold front will advance south-southeastward toward nwrn ca, with rich moisture (pwat values from 1.5-2.0 inches) focused along the front. Ascent with the front will yield a deeply saturated layer favorable for light rain during Wednesday afternoon over del norte county. After Wednesday, quasi-zonal mid upper-level flow is forecast to develop across the region, while boundary layer winds return to |
north-northeasterly. That pattern will support moderating temperatures across the interior and near-zero rain chances. Aviation Marine clouds evident all along the mendocino and del norte coast but not along the humboldt coast. As of 0300 acv remains under clear skies and fog free. The low clouds are moving southward under light northerly flow but it should be at least a few more hours before they reach humboldt bay..If at all. Forecast models have humboldt bay under mfvr conditions through at least late morning but that is looking iffy now. Either wayVFR conditions are still likely in the afternoon. Elsewhere some low clouds are showing up along the eel river area but other inland and interior areas are remaining cloud free. Marine A lighter wind regime and calmer seas will persist through Wednesday before northerlies start to pick back up toward Thursday. Stronger northerlies but sub-gale will persist through the end of the week and into the weekend. A couple of small mid- period swells will also move through the waters from the northwest over the next few days. Eka watches warnings advisories Ca... None. Northwest california coastal waters... None. Visit us at https: |

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. |
