Weather Forecast: May 19 – May 25, 2016

Weather Forecast: May 19 – May 25, 2016

April 2016 recorded above to well above averagewthr.ritchison.1 and 2 precipitation for almost all of North Dakota.  May, on the other hand, has recorded well below normal precipitation to this point. There is potential for this to change over the course of the next seven days. In the short term, the weather is expected to remain dry and very windy at times. This weekend into early next week, the upper-level wind flow will transition to the southwest over the upper-Midwest as a trough forms over the western portion of the United States (Figure 1). Almost all significant rain events in North Dakota are associated with this type of pattern.

Temperatures are expected to be 5-10 degrees above seasonal averages through this weekend with a stiff south wind on many of these days. That wind will be in association with an area of low pressure that will be forming in the Rocky Mountains. That low pressure center will come out in two pieces, one weaker system on Sunday/Monday and another probably stronger piece next week. It will be that second system that will have potential for more significant rain across some portions of North Dakota. It will likely be an event with “winners and losers” meaning widely varying rain totals and may linger off and on through much of next week.

That storm next week will not only have rain potential, but the cloudiness associated with the storm, cooler temperatures for a few days. Yet, through Sunday above average temperatures will create some needed bonus growing degree days. Those projected Growing Degree Days (GDDs), base 34°, 44° and 50° for the period May 19 through May 25, 2016 for some select North Dakota cities are presented in Figure 2.
