Area Forecast Discussion . Updated National Weather Service Billings MT 936 AM MDT Sat Mar 28 2020

UPDATE.

Morning clouds are expected to give way to some sunny skies this afternoon. No shower activity is expected except for some snow showers over the mountains. Breezy conditions will be likely along with slightly warmer temperatures with lower 50s common except for some upper 40s along the foothills. Current forecast remains in good shape so no updates are planned this morning. Hooley

DISCUSSION.

Today through Sunday night .

Well mixed day today will bring gusty winds to the area this afternoon and push temperatures into the 50s. West to northwest winds will gust to 30 mph in many locations this afternoon. There will be a feed of Pacific moisture into the western mountains for isolated to scattered snow showers in the higher terrain, and isolated rain showers in the valleys and foothills. Sunday will be similar to Saturday with a bit less wind but temperatures around 60 degrees. Will continue to see a chance for western mountain and valley showers. Chambers

Monday through Friday night .

Winds will continue to be the main concern for the first part of the work week before the forecast becomes more uncertain due to ensemble spread.

Gap flow winds will increase on Monday allowing for winds to increase to sub-advisory levels due to southwesterly flow and lee- side troughing. The increasing winds speeds will spread from Livingston to Billings areas as the front begins to move through the area on Tuesday.

Uncertainty still remains for Tuesday onward as ensemble spreads are near 50 degrees. High temps for Tuesday have been lowered into the 40s for most locations with some along the ND border seeing the low 50s. This could change as models come into better agreement on the timing of the front. Models continue to differ between the front arriving Tuesday or Tuesday evening but have leaned towards it arriving during the morning, keeping temps on the lower side. Below normal temps are expected for Wednesday and Thursday but just how cold uncertain. Light rain and snow showers will be periodic throughout this time but no significant accumulations of snow are expected. Stay tuned to the forecast as we get closer to this event and details become more clear.

Highs on Monday will warm to 50s in the west to mid 60s in the far east. Tuesday's highs will cool into the 40s with 30s expected Wednesday and Thursday.

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.
