This week has featured a bit of a repetitive pattern with highs in the low to mid 80s each day, partly sunny skies, and scattered thunderstorms. I think the biggest story has been the lack of humidity though, with dewpoints only in the upper 50s the past 3 days. Typically this time of year we see dewpoints in the mid to upper 60s, meaning very uncomfortable levels of humidity. This stretch of comfortable days should continue through the holiday weekend. This upper-level low over the Great Lakes has really helped us out, with cooler than normal temperatures, breezy westerly winds and the lower dewpoints. This system should finally lift out of here come Saturday as a weak cold front pushes it further to the east by Saturday afternoon. This frontal system should move through as a dry front, but a stray, and I really do mean stray storm, may be possible Saturday afternoon. Overall, the weather for the fireworks should be good to go.
Changes to the forecast may be possible for the end of the weekend Sunday as an area of low pressure swings through from the Rockies. A few showers and thunderstorms may be possible Sunday evening, but we will keep you posted on that as models have just recently shown this, and there isn't much of a consensus that this will occur. Low humidity values are expected to continue into late next week, so enjoy this cooler than normal stretch while it lasts!
