Mother Nature always seems to enjoy June because as soon as the month starts, severe weather season begins. It comes as almost no surprise that there is a severe thunderstorm watch effect this Monday evening, June 1st.
As of 5:00 Monday night, the storms were producing large hail near the Kansas/Nebraska border. Some hail reports were near 2" large. They received over 2" of rain in most areas along the Kansas/Nebraska border last night. Most cities within the Omaha Metro received less than a quarter inch of rain. We are in a rainfall deficit right now, but with an active weekend weather pattern, we may close that gap.
As of Tuesday afternoon, the cold front that helped fuel heavy rain producing storms has migrated south into Kansas and Missouri. You can see it outlined in the winds converging on the surface map.

The upper level pattern will shift this weekend and allow several small impulses to travel across the Midwest. Each impulse will spark showers and storms. The upper level winds are also directed over us. This will help steer storms straight across the I-80 corridor for the second half of the weekend.

Timing these small disturbances is nearly impossible right now. We will keep a chance of storms in our forecast each night Friday through Monday. Temperatures will remain below average in the lower to middle 70s, but hail is always a possibility with late spring convection. While we are not expecting an extreme severe weather outbreak right now, isolated hail cases are always in the forecast this time of year.
