Synopsis for the southern oregon coastal waters.. The thermal trough along the coast is expected to peak in strength this afternoon and evening. Conditions hazardous to small craft will continue across all of the waters with more hazardous warning level conditions expected to peak this afternoon and evening for much of the area between 2 and 60 nm from shore south of cape blanco. Winds are expected to begin to diminish Saturday and then, moreso, on Sunday. The latest guidance suggests that a reprieve from advisory level conditions Monday and Tuesday will be short-lived as winds approach warning levels again mid-late week.

(on/off) Help NOTE: mouseover dotted underlined text for definition| Fxus66 kmfr 190407 afdmfr area forecast discussion national weather service medford or 907 pm pdt Thu jul 18 2019 Discussion An update to the forecast is not necessary. Low level clouds in coos and douglas counties have mostly dissipated this evening, while mid level clouds linger across northern california. Those clouds will dissipate overnight as well. But, northerly flow should result in a modest re-development of low clouds late tonight in douglas county to the south of roseburg... Near canyonville. Temperatures, winds, and relative humidity levels on Friday should be quite similar to those from today. A more northeasterly component to the flow in curry county is expected to create a chetco effect with well above normal temperaturest for brookings on Friday and Saturday. High pressure is expected to build during the weekend with a warming and drying trend. Highs have been near normal for most of the month so far, but will be 5 to 10 degrees above normal during the weekend. For Sunday, the 18z model data supports the idea of weak instability for at least a few cumulus buildups and perhaps a few thunderstorms late Sunday afternoon into the evening in southwest siskiyou county and in southern and eastern lake county. Similarly, very weak instability may return in eastern lake county late day on Monday and Tuesday. Any adjustments to the convective forecast will continue to be the main focus going forward. Aviation For the 19 00z tafs...VFR ceilings in the umpqua valley and along the umpqua divide are expected to clear this evening. Conditions are then expected to remainVFR into Friday evening, though with breezy gusty low level west to northwest winds during this evening. -dw Marine Updated 800 pm pdt Thursday 18 july 2019... A thermal trough will strengthen along the coast through Friday. Conditions are hazardous to small craft across all of the waters. The most hazardous conditions, including gale force winds and very steep seas, are occurring from 5 nm to 40 nm offshore from gold beach south. Gusty north winds and choppy seas will persist into the weekend. The thermal trough will weaken Sunday, with winds and seas diminishing at that time. Prev discussion issued 227 pm pdt Thu jul 18 2019 discussion... satellite is showing lingering clouds north of the umpqua divide and along the northern sections of the coast. Elsewhere, cumulus clouds are scattered across northern california and southern |
oregon this afternoon. With the zonal flow continuing aloft, near normal temperatures are expected across most areas for tomorrow. The exception will be brookings as thermal trough will bring warmer than normal temperatures to that area. The thermal trough will persist for the start of the weekend before moving farther inland on Sunday. When the thermal trough moves inland, we'll see high temperatures in the mid to upper 90's in most locations in the west side valleys. This is the warmest time of year and these temperatures will only be roughly 5 degrees above normal. With a trough approaching, the concern then turns to the potential for thunderstorms. As this trough approaches, it will ingest a tropical disturbance and bring that disturbance north into the region. After looking over the thermodynamic profile Sunday night into Monday, we were not that excited about the potential for thunderstorms. There is a little bit of cape, but the atmosphere appears too stable to support thunderstorms. Convective inhibition is showing values from -25 to -50, which is pretty healthy for weakly forced situations. Overall, we'll keep an eye on thunderstorm potential Sunday through Monday. Eventually, a cold front will approach the coast Monday night into Tuesday. Models do show some spotty precipitation in the forecast along the coast and this situation could very well warrant a mention of rain near north bend, but we decided to keep it out the forecast at this time. Temperatures will cool down about 5 degrees Tuesday into Wednesday as this relatively cooler air and a trough moves through. Finally, this trough will move eastward and we'll have a brief period or ridging as the four corners high builds towards the pacific northwest. High temperatures will rise into the mid and upper 90's towards the tail end of next week. -smith Mfr watches warnings advisories Or... None. Ca... None. Pacific coastal waters...

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. |
