Area Forecast Discussion National Weather Service Billings MT 344 AM MST Mon Dec 16 2019
Today through Tuesday Night .
High pressure ridging builds across the forecast area today into Wednesday. This will result in rising heights and mild temperatures. Skies today will continue to be mostly cloudy for areas near and along the Dakota borders with partly sunny skies elsewhere. Mostly sunny skies will prevail Tuesday as the high pressure ridge axis centers over Montana.
The weather impact through the short term will be strong wind gusts for the Upper Yellowstone and Stillwater Valleys tonight into Wednesday. Lee-side troughing will set up resulting in tightening pressure gradients across these areas. The gradient orientation will be more east/west than north/south which will allow for windy conditions from Big Timber to Harlowton. However, at this time, we are not expecting high winds for these areas as 850mb and 700mb winds are not linked well and 700mb winds are progged to be around 40kts. Although the gradient is not perfectly favorable for the Livingston area, it will be quite tight. Model guidance and local guidance are also favoring strong wind gusts. Forecaster confidence is high for winds gusting 50-60 mph from Livingston to Nye. As a result, a wind advisory has been issued for these areas starting early this evening and continuing into Wednesday morning. Highs today will be seasonal with above normal temperatures expected for most areas on Tuesday. Hooley
Wednesday through Sunday .
Extended forecast continues to look warmer, windy and mainly dry through the weekend. Advisory type wind gusts will continue in the gap favored foothills from Livingston to Nye into Wednesday, returning again Thursday night into Saturday after a brief lull. Precipitation chances will tick up for western mountain locations Thursday and continue off and on in the high country through the weekend into the Christmas period, occasionally working down into the foothills. Any lower elevation precipitation looks negligible at this point through the weekend. Longer range models continue to advertise colder with a period of snow heading into Christmas, so a white Christmas Eve/Christmas is still a possibility. Chambers
VFR conditions will prevail today. Isolated to scattered snow showers will continue over SE Montana early this morning with local MVFR conditions, shifting out of the area by late morning. Southwest winds will increase in the western foothills today with gusts of 35 to 50kts by late this afternoon at KLVM. These strong gusts will continue through Wednesday occasionally impacting K6S0 as well. Chambers

Ad by Google
I do not sell or share any user data or anything else for that matter. I do not keep site logs longer than I need to to keep bad actors off the site. Basically, I delete them after looking at them. If you are subject to CCPA, Google ads on this site will not be based on your past behavior so you will likely not see an ad for a lawn mower just because you looked for one at a big box website. I do not believe this site is subject to CCPA but I am doing what I can to follow the guidelines anyway.
The information on this web site has not been checked for accuracy. It is for entertainment purposes only and should be independently verified before using for any other reason. There are five sources. 1) Documents and manuals from a variety of sources. These have not been checked for accuracy and in many cases have not even been read by anyone associated with L-36.com. I have no idea of they are useful or accurate, I leave that to the reader. 2) Articles others have written and submitted. If you have questions on these, please contact the author. 3) Articles that represent my personal opinions. These are intended to promote thought and for entertainment. 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 numerious 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.
