An atmospheric river will continue to bring gusty winds, moderate to heavy rainfall, and potential flooding to southern California and the southern Great Basin through Sunday. Periods of heavy snow will continue as well above 7,000 feet over the Sierra Nevada mountains associated with this atmospheric river. Read More >
Overview
|
Snow began on the evening of Monday April 11th, impacted much of our west and central parts with heavy snow into Tuesday the 12th, and evolved into a blizzard for southeast Montana that lasted into Thursday April 14th. The storm had wide-ranging and long duration impacts to southcentral/southeast Montana and northern Wyoming. Most locations (with the exception of the Shields River and Paradise Valleys) received 8-15 inches of snowfall, while some areas east of Billings saw up to around 20 inches and the Beartooth and Red Lodge Foothills around two feet. |

Snow/Cold
SNOW AT BILLINGS: Snowfall during the morning of April 12th was particularly heavy in the city of Billings. Snowfall rates of 2-3”/hour were observed, and snow piled up quickly. Approximately 10-12 inches fell between roughly 6 am and noon. Total snowfall at the Billings Airport on the 12th ended up being a whopping 13.9 inches. This was the heaviest single day total in April since 1955, and the 6th greatest single day total on record (for any time of year). Additionally, the snow depth of 13 inches observed at the airport on the morning of the 13th was the greatest depth on record so late in the spring.
IMPACTS: The combination of heavy snowfall and strong winds caused significant blowing and drifting snow, especially over southeast Montana where winds were strongest. Some livestock were lost due to the snow, cold and wind. Several school districts closed schools for the day on Tuesday and/or Wednesday. Road closures delayed truck travel across much of the area. The following highways were closed for significant periods of time:
RECORD COLD: An unseasonably cold air mass settled over the region during the snowstorm and lasted through the week. Many daily record low and cold high temperatures were broken from the 13th through the 16th. Some locations even fell below zero, including Melville (-10°), Springdale (-7°), Columbus (-6°), Red Lodge (-4°) and Bridger (-2°). The lows of 4° at Billings and 7° at Livingston on the morning of the 14th were the coldest on record so late in the spring. The following table is a summary of records broken or tied at our four main climate stations during the cold snap.
METEOROLOGY: A cold front on April 9th followed by a chilly air mass across the region on the 10th and 11th were important components to this winter storm, as relatively cold air was already in place when the Pacific system (and even colder Canadian air) arrived. The combination of strong upper level ascent, deep easterly (upslope) winds and temperatures favoring dendritic snow growth led to intense snowfall rates on the night of the 11th and morning of the 12th.
The upper level low deepened and tracked slowly as it moved from Wyoming into the Dakotas, and this was responsible for the long-duration blizzard conditions that occurred in southeast Montana (as well as northeast Montana and most of North Dakota). Overall, the strength, duration and magnitude of cold associated with this spring winter storm made it an event for the history books.
The surface analysis on the right shows cold high pressure surging out of Canada as the storm system moved from southern Idaho into Wyoming. This is an ideal scenario for heavy snow in southern Montana and northern Wyoming.
