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.

DISCUSSION. Today through Sunday .
Localized early morning fog is occurring over our west. As of 1 am, visibility at the Big Timber airport is less than a 1/4SM, and fog/stratus can be seen on satellite imagery near the Beartooth/ Absarokas and Crazy Mountains. Fog coverage may expand a bit over the next few hours, but we are seeing weak pressure rises from the northwest which should help promote some drying. Valley fog could form near Livingston, Billings and Sheridan between now and sunrise . but it should stay localized.
Satellite imagery shows a dynamic low over the Great Basin, strong ridge off the Pacific coast, and a cold upper low over northern Saskatchewan. A shortwave along the NV/UT border will lift to the northeast today, as parent low continues to push south to southern CA. This wave may bring some light snow or flurries to our far south today, mainly Sheridan county, but the confluent flow over our region will keep the brunt of moisture suppressed to our south (it will be a good snowfall for central and southern WY). Will keep low pops going for mainly the Bighorns and their eastern foothills thru about mid afternoon, after which we will see further drying from the northwest. Sheridan could pick up a couple tenths of an inch of snow, and Story maybe a half inch to inch, but that's at the most. Temps today will actually be a few degrees below normal with highs mostly upper 20s to low 30s.
We will transition to flat ridging tonight and Sunday, as our region is stuck in the middle of a split flow across the western CONUS. This will be a dry period of weather, with development of a modest lee side trof promoting an increase in SW-W winds along the foothills. Gusts 30-40 mph are possible at Livingston (i.e. well under advisory speeds). Temps will rise accordingly on Sunday . 30s to around 40 for highs.
Sunday Night through Saturday .
Jet energy remains well to the S and to the W of the area through Tuesday. Model clusters continue to depict an elongated W coast trough from off the Pacific NW coast to the four-corners region. Forecast area will be under ridging through Monday, then SW flow starts to move over the area on Tuesday. Temps will be in the upper 20s to lower 30s on Monday, then a back door cold front moves through the area Mon. night, resulting in highs in the 20s for Tuesday. This period will be dry. For Wednesday through Thursday, the jet moves NE through the area leading to a strongly amplified pattern, with the upper trough offshore and strong ridging downstream over the forecast area. Result of this pattern will be that some moisture is able to move into the SW mountains with a chance of snow. Temps are progged to reach the 40s on Thursday. Most model clusters showed the Pacific trough starting to move inland on Friday, and flow turns zonal over the forecast area. The chance of snow will continue over the SW mountains. NBM kept high temps in the 40s through Saturday. Arthur
Localized fog and stratus will affect areas along and west of KHWQ-BIL-KSHR early this morning. K6S0 continues to report a vsby of less than 1/4SM at times. Fog is not expected to be widespread, but it may increase in coverage thru sunrise. Otherwise, local MVFR due to light snow is possible near KSHR today. The remainder of the area should keep w/ VFR flight conditions today and tonight. SW winds will increase along the western foothills late tonight w/ gusts to 30 kts at KLVM. JKL

These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerous of sources and is presented automatically. 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.
