Marine Weather and Tides
Version 3.4 |
3/3/2018 - There is a new GOES Satellite for the east coast that required rewriting that part of the code. Please report any issues. 6/25/2017 - NOAA is having a major issue that impact the 7 day forecast load times. Many users are reporting problems. The issue has been reported. 5/23/2017 - Worked with NOAA again to speed up the 7 day forecast load times. Thanks to them for being responsive. |

(on/off) Help NOTE: mouseover dotted underlined text for definition| Fxus66 kmfr 240847 afdmfr area forecast discussion national weather service medford or 147 am pdt Tue apr 24 2018 Discussion A rapid warm up will continue through wedensday. In fact, we could see MAX temperatures ranging between 15-20 degrees above normal today and Wednesday, with near record highs possible across the region. While the thermal trough has expanded into our area, the associated pressure gradient has weakened, and offshore flow has diminished. With this change, a southerly wind surge has begun along the coast. Typically, these surges are accompanied by low level stratus invading the coastline, but latest observations show no sign of such a cloud deck yet. The closest low marine clouds are well south of CAPE mendocino, but that does not mean we couldn't see rapid development of clouds this morning or today. The marine stratus is then expected to slowly march northward through tonight. Meanwhile dry and very warm weather will continue through Wednesday for many inland locations as the thermal trough shifts inland over the west side valleys. Wednesday should be the warmest day of the forecast period with a few spots touching 90 degrees in the rogue valley, mid to upper 80s in the umpqua basin, and upper 70s to near 80 degrees east of the cascades. The record highs in medford for today and Wednesday are 90 and 91 degrees respectively. The current forecast highs are just below these values, but only by a degree or two. Meanwhile, in roseburg, the record highs for today and Wednesday are 82 and 84 degrees, both of which are expected to be beat by several degrees. The next area of concern is the location of the upper low that will be lurking offshore Wednesday night through Thursday. There's better agreement among the models with the position and track of the cutoff low, but still some differences. The low will slowly inch eastward towards our forecast area Wednesday night through Thursday. None of the models are showing any obvious signs of instability ahead of the cutoff low and the best dynamics will still be offshore, so we'll keep it dry Wednesday night into Thursday morning. Things could interesting on Thursday, especially in the afternoon and evening. The general consensus is for increasing instability along with a trigger mainly east of the cascades. The models may be too bullish with the amount of instability along the cascades from crater lake north, especially given the fact there is still some snow pack there, but some elevated instability could still trigger an isolated storm or two. Therefore, have kept a slight chance of thunderstorms in the forecast along and east of the cascades. The coverage area of showers is expected to increase Thursday night as the upper low moves closer to the oregon coast. Model guidance continues to be in decent agreement regarding the closed low as it tracks onshore Friday and passes directly over the region this weekend. As deterministic solutions look similar to each other as well as their respective ensembles, confidence |
in the unsettled, but cooler, weekend remains high. What this means in terms of weather on Friday is a marked increase in the potential for showers, noticeably cooler weather, and lowering snow levels. There are, of course, some difference in the details, but regardless of the model choice, southerly flow ahead of the upper low should target the mountains over central siskiyou county on up into the oregon cascades for the most shower activity. In addition, instability and dynamics will be favorable for thunderstorms on Friday afternoon and evening, especially in the mountains and east side. Under a southeast flow pattern aloft, it's not inconceivable that a storms drifts out over the west side, but the chance of that is low enough that we'll keep it out of the forecast for now. Just keep in mind that it's possible on Friday. As mentioned yesterday: model differences notwithstanding, the low will move in over the weekend and result in cool, showery weather area-wide. It's really only a question of whether it comes right in and produces a lot of valley rain and mountain snow showers or, as upper lows often do, drifts in south of us and deals us only a glancing blow. A direct hit from the upper low seems slightly more likely this time, and pops remain on the high side, with considerably lower temperatures. There will still be a chance for thunderstorms over the weekend, but it doesn't look overly exciting due to instability-limiting factors such as cloud cover and mountain snow pack. Early next week we get into drier northwest flow behind the departing upper low which will help us warm up and dry out. -bpn map trw Aviation 24 06z TAF cycle... Oth is the main forecast challenge as moisture is moving into the area behind the thermal trough that has lifted into northern oregon coast. Models have been inconsistent at flight categories with some introducing lifr tonight then backing off completely. This forecast is more of a hedge with MVFR visibility and scattered very low clouds tonight. However this may be the case where oth will go down hard to lifr or not at all. ElsewhereVFR conditions continue under clear skies. -fb Marine Updated 200 am pdt Tuesday 24 april 2018... Conditions will be relatively calm through Friday. Seas will increase this morning to around 8 to 9 feet at 15 seconds as west swell builds into the waters, but conditions will remain below small craft advisory. Seas subside late this evening through Wednesday. Winds will remain light, generally below 15 knots with weak low pressure over the waters, but will become southerly late tonight and continue through the week. Small craft conditions could be possible again next weekend as northwest swell will builds in. Br-y Mfr watches warnings advisories Or... None. Ca... None. Pacific coastal waters... None.

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. |
