Marine Weather and Tides
8/26/2020 The 7 day forecast is taking about 5 seconds to load but it will eventually load. NOAA is still working on it.
8/18/2020 NOAA continues to have trouble. Wind guest will occasionally be left off graphs. I am working with NOAA to resolve the issue.
12/16/2019 NOAA is having trouble with requests that include wind gusts. I am posting graphs without wind gusts until it gets fixed.
10/9/2019 Updated the Marine Zones.
9/4/2019 Fixed the weather maps due to NOAA moving them.
7/25/2019 New feature in the Airports section gives a link to 5 minute updates for data reports.

Area Forecast Discussion National Weather Service Salt Lake City UT Issued by National Weather Service Grand Junction CO 845 PM MST Fri Nov 27 2020
SYNOPSIS. High pressure will remain in place through the first part of the weekend. A weak disturbance will cross the state Saturday night into Sunday followed by a return to high pressure early next week.
UPDATE. Issued at 845 PM MST Fri Nov 27 2020
Current forecast remains on track with little change noted in the latest model runs arriving this evening. Anticipated return of stratus cloud deck across eastern Box Elder County should reappear for a few hours around sunrise and potentially lingering through midday before dissipating. Also expecting some high cloud cover to drag across the northern zones on Saturday ahead of the dry front that nudges in Saturday night and Sunday.
With high pressure building back across the Great Basin, light winds, and a strong inversion per the 00Z sounding, a return of hazy conditions appears likely and meshes nicely with the latest Air Quality forecasts.
Only minor adjustments to the forecast grids to fit currents trends for the remainder of the overnight hours.
SHORT TERM. (Through 12Z Monday) Issued at 326 PM MST Fri Nov 27 2020
High pressure continues to build into the state this afternoon. Stratus has eroded across the areas impacted this morning including the Bear River Valley. HREF indicates additional stratus may develop in primarily this area and potentially rural areas of western Iron and Beaver Counties. Right now, have patchy dense stratus in the forecast for the Bear River Valley tonight. Will monitor other areas for development.
Utah Department of Air Quality continues to forecast yellow/moderate conditions into the weekend for much of the Wasatch Front and the Cache Valley. Expect increasingly visible haze across these areas through Sunday.
An upper trough will dig into the Plains, pushing a weak but dry front into the state Sunday. This front seems unlikely to drastically improve inversions/haze.
LONG TERM. (After 12Z Monday) Issued at 326 PM MST Fri Nov 27 2020
High pressure remains in place at the beginning of the extended forecast period allowing continued quiet weather and above average temperatures to continue. However, a brief change looks to be on the way as a trough still remains on course for the northern Intermountain West late Monday/ early Tuesday. The details of this trough remain considerably uncertain at this time as mean ensemble guidance is now beginning to diverge. Where both the EPS and GEFS means once agreed on a trough to clip the northern third of the forecast area, they now suggest very different solutions to the progression of the feature.
Ensemble guidance seems to continue to favor a more progressive system scraping across the northern half of Utah and southwest Wyoming. Roughly 75% of ensemble members are supporting this scenario, while the other 25% fall more in line with that of the EPS mean and deterministic. The solution from the EPS mean, as well as the deterministic ECMWF, has shifted from a transient disturbance to a trough that looks to dive out of the PacNW region southward into the NM/AZ region. This solution would favor a bit more widespread precipitation over the high terrain across the forecast area (rather than just the northern third). As stated before, this solution looks to be more of an outlier, therefore, have continue to maintain PoPs across the northern mountains for late Monday/ Tuesday. In either scenario, minimal impacts are anticipated. The associated cold front from this system will likely drop temperatures over the northern half of the area at the very least. Still some uncertainty on how much of the state will be affected by this/ how far the cooler temperatures will spread.
Looking past this time period, there are hints at a blast of cold air pushing in from the east shortly thereafter, however, it still seems too early to call the shots on this one. High pressure does, however, look to be more certain as we should find the eastern Great Basin under the eastern periphery of a significant 500mb ridge through early December. Unfortunately, anticipating largely dry conditions to prevail for a while.
AVIATION. The SLC terminal will see VFR conditions through the night with some high clouds. Southeast winds are expected to persist through the early morning hours, before switching back to the northwest by midday Saturday.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors.

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.
