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.

SHORT TERM. (Tonight through Sunday night) Issued at 223 PM MST Sat Jan 16 2021
As expected, the shortwave that brought the mostly light snow to the mountains has quickly moved off to the east with only some flurries remaining, and those are far and few between. For now, the upper level jet is moving from north to south causing enough lift for some high clouds, especially up north. The rest of the CWA is seeing a partly cloudy day with some fairly warm temperatures being reported.
Synoptically, a large area of high pressure remains set up just to the west of the southern Cali coast while a deep low moves from the Ohio River Valley up into New England. This places our CWA in some northwesterly to northerly flow through early Monday morning. During the day Sunday, another trough sets it sights on the CWA albeit a bit stronger than the one we saw move through last night. For Sunday then, south of I-70, mostly sunny skies expected while areas north will see a few more clouds, especially along the WY border. As the trough approaches, we can expect some snow for the usual suspects..the Park Range, Flat Tops, Elks, and Sawatch Ranges. The snow will begin around 9PM, give or take, and continue through Monday morning . 2 to 5 inches looks a safe bet for now. The evolution of this wave gets interesting as we head into the start of the work week Lots of moving parts.
LONG TERM. (Monday through Saturday) Issued at 223 PM MST Sat Jan 16 2021
An increasingly amplified and blocky pattern in the mid and high latitudes will result in a challenging long term forecast next week. Various ensemble teleconnection indices favor a negative NAO, a neutral PNA becoming negative, and an EPO that is also neutral becoming negative. Taken altogether, this leads to next week's mean 500mb pattern featuring a strengthening East Pacific and Aleutian ridge (-EPO), a trough over the western CONUS (-PNA) and a highly anomalous ridge over Greenland (-NAO). In terms of sensible weather, a return to stormy and active weather is likely, particularly Monday into Tuesday and again late in the week into next weekend.
Starting with Monday into Tuesday, a strong, positively tilted trough over California will dig southward into the eastern Pacific Ocean / Baja California. Meanwhile, another strong positively tilted shortwave trough will dig southward from the Pacific Northwest and close off over the Great Basin. By Tuesday, these two system will merge, forming one very large closed mid-level low just off the coast of southern California. Initially, northwest upslope flow will favor the northern mountains of Colorado on Monday with 2 to 4 or 3 to 6 inches of snow likely. As we head into Tuesday (and perhaps Wednesday), however, mid-level flow will switch out of the south and southwest as our two aforementioned systems merge. Diffluent flow coupled with more moisture to tap into will lead to the San Juans and portions of the central mountains becoming the favored ranges for more significant precipitation. While we're still several days away, confidence is increasing for a substantial winter storm with the potential for snow accumulations of a foot or more. This system is certainly one we'll be monitoring closely over the next few days.
Snow may linger into Wednesday, but current model consensus shuts off most if not all precipitation by Thursday as the closed low opens up into a wave and treks eastward across the southern Four Corners and into the southern Plains. If this process is slower to occur . or tracks farther north . precipitation may extend longer into the middle of next week for the San Juans. For now, we're leaning towards a drier solution. After that, the next period we're watching is Friday into the weekend, where yet another closed, moisture-laden storm is in the pipeline.
AVIATION. (For the 06Z TAFS through 06Z Sunday night) Issued at 1037 PM MST Sat Jan 16 2021
Expect VFR conditions for the next 24 hours as some high cirrus drifts overhead from the north overnight into the day on Sunday. No precipitation expected with CIGS above ILS breakpoints. Winds will remain light and terrain driven.

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.
