Those narrow strips of reflectivity on the NEXRAD radar are actually the leading edge of a strong cold front, which will continue to push south and east today. Much cooler weather is on the way for tomorrow and even more so on Friday, where some places will be stuck in the 40s!

Flooding will also pose troublesome with much of the Midwest saturated from recent heavy rains.
On the left is the latest 6-10 day temperature outlook from the Climate Prediction Center. It shows the likelihood of temperatures below the normal mean temperature during a specified time period. For those that follow these maps, dark shades of blue are extremely rare. In recent days the dark blues are appearing as frequently as the did earlier in the Spring during the winter that never seemed to end. Another prolonged period of even colder weather has popped up in the computer models. The European model has another strong cold front passing through early next week with accumulating snow in northern Minnesota, we will see how this one plays out in coming days.
With it being the first major shot of cold air, we will closely watch how the models handle it to get a gauge on the rest of the summer and into Autumn for future forecasts.
Just for kicks, below is the EURO model for next Monday as the cold front pushes through...

Just to give a snapshot of what some of the models are outputting...here is the latest EURO model run for minimum temperatures next Friday night and Saturday morning. Showing widespread lows in the 20s! While this scenario is extremely unlikely, record low temperatures may be within reach. The GFS is outputting similar, yet more conservative numbers. One rule of thumb this summer is that the EURO does tend to go cold a week out, it will be interesting to watch the cold unfold in the models throughout the next several days.
