Back to average, and then below?

Long-suffering Memphians ready for a break from summer heat finally have a forecast they can smile about! Thanks to a retreat and slight weakening of the massive high pressure centered over the southern Plains, the Mid-South has been positioned in "northwest flow" - where the upper air flow is from northwest to southeast - that has brought some relief from the heat of June and July.  Though not everyone has benefited from scattered showers and thunderstorms, the closer-to-average temperatures have been a welcome respite.

As we head into the weekend, a cold front will move into and completely THROUGH the Mid-South on Saturday.  It's been a long time since we've had a front that actually moves far enough south to usher in some more forgiving air that will be less humid and cooler, but that is what this one brings. Along the front, expect scattered thunderstorms that could bring some gusty wind and heavy downpours on Saturday.  By Sunday, the humidity will be dropping and temperatures could struggle to reach 90 under full sun.  The same is expected for early next week.  Though temperatures will slowly rise a degree or two each day next week, humidity will still be decent with dewpoints in the 60s. The best part of lower dewpoints is the morning low temperatures.  Everyone (including in the city) will see lows in the 60s to start next week.

Enjoy!!
