Unusual weather pattern for a July weekend

In the wake of a cool front that passed through the region yesterday, much driver and somewhat cooler air has infiltrated the Mid-South today and will continue tomorrow.  This is resulting in highs in the upper 80s, dewpoints in the upper 50s to lower 60s, and a northeast breeze that makes it feel rather comfortable for mid-July!

Heading into the weekend, an upper-level low pressure system will affect the area, but will arrive in an unusual way - moving from east to west across the region, a retrograding pattern!  Watch the short video below as MWN meteorologist Erik Proseus explains the forecast motion of the upper low and what it means for the Mid-South.

Chances of showers and thunderstorms would be more likely on Saturday if it were not for the dry air in place.  However moisture increases Saturday night into Sunday as surface high pressure moves east and wind gets more of a southerly component. The increased moisture, plus being on the eastern side of the low, will mean a little better chance of scattered precip on Sunday and Monday. By Tuesday, and continuing throughout next week, the Mid-South will be back into a more typical summertime pattern, with slight chances of thundershowers each afternoon and evening, highs well into the 90s, and humid conditions we would expect from a Memphis summer!
