Marine Weather and Tides
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. Tonight through Thursday night .
Satellite imagery shows an upper low over central Saskatchewan, cyclonic W-NW flow over our region, and a shortwave approaching from north central MT. There remains some showers in far southeast MT associated with a morning wave, and this activity will exit Carter county soon. Upstream wave will help to produce isolated showers this afternoon and evening, mainly over/near the mountains and NW-flow upslope areas, but otherwise there is not enough instability/moisture to do much. Later tonight, in the wake of the shortwave, there will be a period of mid level frontogenesis in a region of very modest elevated instability, which should be enough for isolated overnight showers mainly east of Billings.
Surface high settling over our east combined with building upper level ridge from the west will result in a period of east winds, capping and dry weather Thursday and Thursday night. Temps tomorrow will be a bit cooler than today per the poor mixing, despite the rising heights.
Friday through Tuesday .
An upper level ridge will move eastward over southeastern Montana allowing for temperatures to continue to warm into Sunday with possible records being broken.
Ensemble runs continue to keep Saturdays temps in the 80s. Models are coming into better agreement with convection Friday and Saturday afternoons. A slight chance of PoPs continues during this period as there is still uncertainty in the location of storms. There is moderate instability along with shear in the atmosphere that would allow for strong to severe storms to form mainly along the foothills and out towards Billings. Capping continues to be the big inhibitor in the atmosphere which could limit the formation of storms. Given we are still 4 days out, it is hard to forecast just how strong the capping will be. We will have to see how it plays out over the next few days and will make sure to update the forecast accordingly. High elevation snow melt will also cause rivers to rise early to mid next week. Rivers will have faster flows and increased bank erosion. Showers and thunderstorms are expected to continue into early next week.
Another element of this upper ridge will be the potential for near record heat on Sunday. The record high temperature for May 31 is 92F for the three stations Billings, Miles City and Sheridan.
High temps will warm into the 80s on Friday and Saturday. High temps will then warm again into the upper 80s to mid 90s on Sunday before cooling back into the 80s.
VFR flight conditions will prevail through Thursday. Mountains may be occasionally obscured in isolated rain/snow showers. JKL

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.
