First measurable snow of the season likely tonight
Winter Weather Advisories in effect
A strong area of low pressure will move out of South Dakota this evening and pass through the Fargo, ND area overnight tonight. In doing so, this area of low pressure will pull cooler air down from Montana and into our region. As it does so, moisture present from this system will allow for scattered rain showers to begin developing during the early evening. As the temperatures drop, these scattered rain showers will transition over to snow showers.
Depending on how much moisture is available, the scattered snow showers could give way to a near-steady snow during the overnight hours. Snow fall rates may be enough to overcome the warm ground temperatures and thus, snow fall accumulations will be possible tonight.
These snow showers will likely still be around during the morning hours, but will then gradually taper off during the afternoon as the low pressure center moves into Canada. Decreasing clouds will likely follow, and this will give way to mostly clear skies by Monday Evening.
New snowfall accumulations of around 1-2 inches will be possible in the eastern half of Stark County, and around 2-4 inches will be possible in the western half - including Dickinson. The snowfall totals will be on the lower ends of those ranges should the snow remain scattered throughout the overnight hours. In addition, some sleet may get into the mix which could also lower snowfall totals.
Aside from the snowfall, windy conditions will also be present. Winds will gradually increase throughout the evening and overnight tonight from the northwest, and by sunrise Monday morning, winds could already be gusting upwards of 40 mph. These steady northwest winds will be with us throughout the day, possibly gusting up to 50 mph before diminishing towards the early evening hours.
Not surprisingly, temperatures will also be on the drop tonight with overnight lows in the mid-20s likely across the area. Temperatures may not rise much on Monday Afternoon, and highs in the mid to upper-30s are looking likely.
Temperatures will then rebound back into the mid-40s for highs on Tuesday, and then possibly into the low to mid-50s on Wednesday depending on the next system. This next system could pass through on Wednesday Night, but right now it appears that only a couple of rain showers of snow showers will be possible, and not much else. Highs return back into the mid-50s by the end of the work week.
