Regional Weather Forecast
National Weather Service Bismarck ND
228 AM CDT Tue Mar 19 2024 /128 AM MDT Tue Mar 19 2024/

Temperatures will trend cooler for most locations today, as a 
cold frontal passage moves southward across the region. Highs 
today will range from the upper 20s in northern Minnesota, to
still mild at around 60 across western South Dakota. 

A significant weather pattern change can then be expected
Wednesday and onwards, as temperatures trend much colder and
precipitation chances return to the Northern Plains. Accumulating
snow chances increase Wednesday into Thursday, with up to around 5
inches of snow forecast through Thursday night for portions of the
Northern Plains, while other areas see little if any snow. 

A more intense round of winter weather is then possible over the 
weekend across much of the Northern Plains and Upper Midwest, with
the potential to disrupt travel for many. If you have travel plans
this weekend through early next week, you will want to monitor the
latest weather forecast information.
