The northern plains are known for rapid shifts in the weather and Sunday into Monday was yet another example of this. On Sunday morning, most of North Dakota and northwestern Minnesota recorded a low temperature in the -20s. Then on Monday morning when we were all waking up, the temperatures for much of the area were in the 20s again, but this time, the positive 20s. That means that the temperature rose as much as 50 degrees in some backyards during that 24 hour period. With about 25 degrees coming during the day on Sunday and another 25 degrees overnight. Similar temperature changes have happened before and will happen again, but it certainly is not an event that happens frequently.
