10/6/2018 Colors of tide XTide graphs changed to emphasize that they were upgraded. See next note. Comments welcome. 10/4/2018 I have fixed XTide and updated the harmonic files. There were some name changes so you might have to click EDIT to find the new station name. |

(on/off) Help NOTE: mouseover dotted underlined text for definition| Fxus66 kmfr 212136 afdmfr area forecast discussion national weather service medford or 236 pm pdt Thu mar 21 2019 Short term Tonight through Sunday night... The band of clouds across lake, modoc, and northern klamath counties continue as part of a tail to a low pressure system centered well off the coast of vancouver, british columbia. A few light showers may be associated with this cloud band, but overall expect things to be light, if any. In fact, precipitation may dry up completely tonight as the upper low departs and the next front approaches the coast. On Friday, the next front arrives and will bring widespread valley rain and high mountain snow to the region. Precipitation amounts don't look impressive, but eventually everyone should see some measurable rain or snow with this front. That being said, the heaviest amounts will be along the coast and the coastal range, where brookings could see up to three quarters of an inch of rain with this system. Although it may not do much to well-established roads, it will be curious to see how the slide on highway 101 reacts to this bit of rain. As this more active pattern will continue for the next several days. Snow levels will be around 5000 feet, and could drop to 4000 feet in showers on Saturday. Overall, not expecting any impacts for the passes, but there could be some light snow, even on siskiyou summit. This front will also bring breezy conditions to many of the usual areas. It doesn't look like any land areas will reach advisory level wind speeds, but it will be breezy and gusty nonetheless. The front moves through Friday night, then the upper trough will move overhead Saturday with considerable shower activity expected. A slight chance for thunderstorms exists on the west side Saturday afternoon and evening as instability and moisture will be plentiful enough. It is worth noting that the models are also indicating these conditions across the cascades and eastward, but snow depths of several inches (to feet) are great at dampening the surface based instability. As things clear out on Saturday night, low temperatures will drop very low. Lows will be in the low 30s west of the cascades with mid to upper 30s at the coast. Meanwhile, temperatures will be well-below freezing across the cascades and east. Although growing season has not officially started, except for many of the early varieties (which can largely handle these temperatures), there could be some frost cold temperature issues if you were impatient like me and got some plants early during last weekend's warm-up. Although Sunday morning will be dry, the next system appears to arrive by Sunday afternoon or evening. The main impacts of this system will occur on Monday, and is detailed well in the long term discussion. -schaaf Long term Monday through Thursday, march 25-28, 2019... unsettled weather is expected much of next week, though we may catch a break on Tuesday. The upper level pattern will feature a broad closed low out around 45n and 140w on Monday. A frontal system associated with this low will move onshore Monday morning and through the area bringing a period of steadier precipitation across most of the CWA through Monday evening. Heaviest precipitation will be from the coast ranges of SW oregon to western and central siskiyou county, where amounts of 0.50-1.50 inches are likely. Snow levels still look to be about 4500 feet with most accumulating snow occurring above 5000 feet. |
Expect a period of steady south to southeast winds pre-front in the morning, then winds shift to SW and remain breezy as the front moves through. Precipitation becomes more showery following the frontal passage. We've added a slight chance of thunder to the immediate coast and coastal waters as mid-level instability increases behind the front. We're expecting broad SW flow aloft to set up over the area Monday night into Tuesday, and while isolated to scattered showers could remain, most areas should catch a break in between fronts. The closed low will pinwheel southeastward offshore sending another short wave impulse and frontal system through the area mainly Tuesday night through Wednesday. Once again, the bulk of the moisture precipitation is expected across our southern and western zones, but areas to the north will see some precipitation too. A showery pattern will continue with moist, onshore flow Wednesday night through Thursday as the closed low offshore gradually opens up into a trough and crosses the pacnw. -spilde Aviation For the 21 18z tafs...VFR is expected to prevail across the region through the afternoon. A front will approach the area overnight with MVFR ceilings, increasing south winds, and precipitation arriving at the coast overnight. Deteriorating conditions will spread east through the morning, with rain overspreading all terminals by midday Friday. Freezing levels are expected to remain well above 5000 ft asl throughout the taf period. -bpn Marine Updated 200 pm pdt Thursday, 21 march 2019... Offshore buoys are beginning to detect the arrival of long period swell this afternoon, which will continue to build into the coastal waters through this evening and tonight. Meanwhile, satellite imagery shows a front lying offshore, which will push into the region tonight and pass onshore Friday. Expected south gales and very steep wind driven seas to develop ahead of the front as it sweeps across the waters Friday morning though Friday afternoon. Elevated long period west swell will continue through Saturday and into Saturday night, producing hazardous bar conditions and higher than average surf before diminishing Sunday morning. After a brief break in the action Sunday, another robust frontal system is expected to arrive Monday, but the latest model solutions suggest it could weaken significantly as it arrives. Due to the weakening trend of the front, timing and strength are likely to change over the next several forecast cycles, but gales may be possible Monday morning, with steep to very steep seas persisting into Monday night. Conditions should improve by Tuesday, but long- term guidance suggests unsettled weather will continue into next week, although exact details are uncertain at this time. -bpn Mfr watches warnings advisories Or...

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. |
