Don't put your shovels away just yet - Winter isn't over
April 10, 2020
The National Weather Service in Great Falls has Havre, the Hi-Line, and much of north- and south-central Montana under either a winter weather advisory or a winter storm warning.
For Hill and Blaine Counties, the area is under a winter weather advisory starting at 6 p.m. tonight and lasting through 6 p.m. Saturday. The advisory says the area could receive between 2-4 inches of snow at lower elevations, while the Bear Paw Mountains could see between 4-8 inches.
Impacts listed in the advisory include poor road conditions, including low visibility and blowing snow, as well as severe stress to newborn livestock.
As for Havre's forecast, the NWS in Great Falls is forecasting a chance of rain this afternoon and this evening, turning to mainly snow after midnight. Snowfall chances are above 60 percent and Havre is predicted to receive between 1-3 inches. Saturday's snow totals are much lower as Havre has just a 30 percent chance of snow showers in the morning, with less than one inch of accumulation. Much of the U.S. Highway 2 corridor between Chester and Harlem is under the same forecast.
The winter storm warning is farther south, including the Loma, Fort Benton and Great Falls areas. There, snow totals are predicted to between 3-6 inches both Friday and Saturday, with 6-12 inches at higher elevations.
Below-average temperatures are also set to return with this weekend's snow event. Today's high in Havre is forecast at 47 degrees, with a low of 25 tonight. Saturday's high is predicted to reach just 30 with a low of 17, while the high for Sunday is 22 with a low of 18, and Monday calls for just high of 36 with a low of 22. Average temperatures for this weekend are 54 degrees with a low of 30, so Havre will fall well-below its normal, for at least the next three or four days.
A gradual warmup is forecast for next week, but National Oceanographic and Atmospheric Administration has forecast that slightly below-average temperatures will remain in place for the second half of April in north-central Montana.
The NWS in Great Falls also said in a Tweet to the Havre Daily News that this weekend's event will put Havre and Hi-Line about a week behind for spring vegetation. According to the NSW, Havre's first day of green-up is April 14, but, this weekend's cold snap will probably set that back a week to 10 days.
