Discussion
Temperatures will jump today ahead of a strong cool front that is advancing our way from the Upper Midwest with afternoon highs likely near the 80 degree mark. The arrival of the cool front late in the day/early tonight may be accompanied by some strong-to-severe thunderstorm activity as several ingredients will be in place (e.g., high humidity, upper-level support, temperature clash). As has been the case during much of the summer season, the frontal passage will not be the end of the story as this one - just like many prior - will stall just to our southeast. Low pressure will ride up along the frontal boundary zone on Thursday and likely spread more rain into the region from later tomorrow into Friday. The weekend still has some hope as high pressure should take control likely providing us with dry conditions and comfortable temperatures.
