Fxus66 keka 221039 afdeka area forecast discussion national weather service eureka ca 339 am pdt Thu aug 22 2019 Synopsis A warming trend is forecast to take place across northwest california through early next week. Warm to locally hot conditions are expected along with near zero chances for precipitation. Discussion A relatively potent upper disturbance that aided in light rainfall across the redwood coast during Wednesday is exiting east across or wa early Thursday morning. Patchy fog and drizzle were occurring over portions of coastal nwrn ca in the wake of the or wa disturbance... But the boundary layer is forecast to dry out this afternoon and aid in clearing skies that will favor mild temperatures near sea level... Ranging to locally hot conditions across interior valleys. An upper-level anticyclone is forecast to become centered over the region by early next week. Increasing subsidence aloft and warming boundary layer temperatures, combined with abundant sunshine potentially extending offshore, indicates that hot temperatures will be probable during the Monday Tuesday Wednesday time frame. Otherwise, building heights aloft will yield near-zero precipitation chances during the next seven days. Aviation Areas along the coast are seeing moist conditions this morning. Patchy fog has developed this morning and is bringing periods of lifr conditions to the coastal areas. This is expected to lift this morning and clear out by late this morning as mixing increases. Temperatures aloft have cooled making the inversion fairly weak which should help bring mostly clear skies this afternoon. Breezy north winds are also expected with gusts of 20 to 30 kt this afternoon at the coast. Currently there are mid level clouds over the interior but most areas, aside from the coastal river valleys, are not seeing fog. Tonight offshore flow develops and this may keep the del norte coast clear. Low clouds are possible around humboldt bay once again while the inland areas remain clear once again. Mkk Marine An upper level trough and associated frontal boundary

moved through the area Thursday. High pressure has started to build into the area and northerly winds are increasing. These are expected to peak tonight before the gradient starts to relax. The northern outer waters are expected to see gale force winds this afternoon and tonight and the gale warning looks on track. The southern waters and the inner waters may see a few gale force gusts especially near the capes, but they are not expected to be widespread enough to warrant gale warnings. These northerlies will generate large and steep seas into the southern outer waters and the hazardous seas warning remains on track. 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. Friday and into the weekend 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. Early next week winds will continue to diminish. By mid-week models are trying to show a trough or upper level low moving into the area again. 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 Eka watches warnings advisories Ca... None. Northwest california coastal waters... Small craft advisory from 5 pm this afternoon to 5 pm pdt Saturday for pzz450. Small craft advisory until 3 pm pdt this afternoon for pzz470. Gale warning from 3 pm this afternoon to 5 am pdt Friday for pzz470. Small craft advisory from 11 am this morning to 5 pm pdt Saturday for pzz455. Small craft advisory until 9 pm pdt this evening for pzz475. Hazardous seas warning from 9 pm this evening to 5 pm pdt Friday for pzz475. Visit us at https:

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.
