Area Forecast Discussion National Weather Service Billings MT 342 AM MST Sat Dec 14 2019

DISCUSSION.

Today through Sunday Night .

An unstable northwest flow aloft will continue over the forecast area today. A weak disturbance within the flow will bring isolated to scattered snow showers across the area. High temperatures today will be 5 to 10 degrees colder than Friday as a result of the cold front that brought the rain and snow for some locations on Friday. This moisture, along with calm to light winds, resulted in the formation of widespread fog Friday afternoon through early this morning from Golden Valley and Musselshell Counties south into Sheridan County. Dense fog continues for much of the above mentioned areas. Model guidance keeps the lower levels saturated through late morning before some mixing begins to occur. As a result, we have extended the dense fog advisory through late this morning. The scattered snow showers will move south into Wyoming by late afternoon leaving just lingering chances along the border into the evening.

The northwest flow aloft continues Sunday but snow shower chances will be confined to the Beartooth/Absaroka Mountains. Pressure gradients from Big Timber to Livingston and along the foothills will begin to tighten during the afternoon, but especially Sunday evening and night. This will bring a return to windy conditions with some gusts possibly reaching advisory levels. Highs on Sunday will be slightly warmer due to the downslope flow. Hooley

Monday through Friday .

No major changes to the going forecast. Overall a quiet weather pattern with temperatures increasing mid to late week as broad ridging builds over the area. The warmth comes at the price of increasing winds across the area, and western foothills could see strong winds starting Monday night and lasting into Friday. The only mentionable precipitation at this point looks to be mountain snow showers Thursday into Friday. Longer range models hinting at a pattern change that could bring snow and colder air just ahead of Christmas. Chambers

AVIATION.

Local VLIFR conditions will continue into mid morning over central areas around KBIL. Further east toward KMLS/KSHR/KBHK MVFR to IFR conditions can be expected with scattered areas of fog and a broad area of low ceilings. A disturbance moving west to east across the area this morning will produce areas of light snow, and will also mix out the low ceilings and fog. Expect VFR conditions by mid afternoon as winds turn westerly.

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.
