This recent weather has been due to an upper-level low pressure system that has stuck around the region, quite literally, being wedged in between two dominant high pressure systems in the western U.S. and western Atlantic.
|The recent cool spell is due to the presence of blocking high pressure over the western Atlantic and western U.S., while a large trough and upper level low pressure system dominated the Mississippi Valley region - literally with nowhere to go.|
So what does this all mean for the 4th of July?
Wednesday into Wednesday night looks the best, with limited cloud cover, pleasant temperatures, and very low precipitation chances for an evening of fireworks. Heading into the 4th of July, clouds and chances for rain increase (slightly) as well as warmer temps and higher humidity. Looking ahead to the weekend, the summer-like pattern looks to stick around with more chances for rain throughout. The bright side is our temps should stay capped out near 90 on the days with the most sun - it certainly could be worse this time of year!
