Weather Forecast: June 9 – June 15

This week there will likely be two weather words used the most - hot and humid. Another word that may come into play will be “severe” as the potential will exist for some stronger storms in the next several days as well. The heat that is expected will not be spread over the entire region equally, in fact, there may be 10 to 15 degree temperature spreads on some days across North Dakota into northwestern Minnesota. Yet, at least some NDAWN (North Dakota Agricultural Weather Network) stations will probably hit 90° + today (Thursday) through Sunday with temperatures 10 to 15 degrees above average on many of those days (Figure 1).

Not only will temperatures have the potential to reach or exceed 90° F, but the dew points are expected to be around 70° in some locations. Dew points in the mid to upper 60s will make most individuals sense that it is “humid” outside, whereas, 70° dew points usually get equated with a “tropical” feeling. Like the temperature, there will be noticeable dew point spreads on any given day across the region, and western North Dakota, in particular, will record much lower dew points than eastern North Dakota and western Minnesota on most days. On a side note, humidity forecasts will begin in this section of the Crop and Pest Report next week.

Two main thunderstorm periods will occur in the next several days - one tonight through Friday morning and another on Saturday night into Sunday. Isolated storms are possible at other times. These two main periods will likely bring some severe weather to the region as well as localized heavy rain as the storms pass through. The projected Growing Degree Days (GDDs), base 50°, 44° and 34° for the period June 9 through June 15, 2016 are presented in Figure 2. Temperatures will be cooling down early next week, but with the projected high temperatures this weekend, GDDs will be obviously quite high during this period.
