Cooler and drier air filters deep into the South behind a frontal boundary

The coolest airmass in years in the month of August,  filtered deep into the South over the weekend,  behind a fairly strong cool front, Friday night into Saturday.

High temperatures under full sunshine only achieved the low and mid 80s, with some areas, remaining in the upper 70s over the weekend, which is almost unheard of outside of cloud cover and rain showers.

Tupelo tied a record low maximum temperature of 78 degrees  on Sunday, meaning this is the lowest ever recorded high temperature on that date. (August 23rd)

But the overnight low temperatures have been the main story.

Normal low temperatures across the state average around 70, but over the weekend and this morning, lows have averaged in the upper 50s and low 60s. (10-15 degrees below normal)

Monday morning would bring the coolest reading over this period, with many areas across the state breaking or tying record low temperatures.

The capital city, Jackson tied a record low temperature of 57 set back in 1931.  A record that has stood for more than 70 years!!

It has been five years, since the state has experienced, widespread low temperatures in the 50s, during the month of August.

This very cool airmass will remain in place through at least mid week.

Low temperatures  will likely break records for the second night in a row across the state.

It goes without saying, these temperatures are very unusual, but also very pleasant, and I am sure no one is complaining about this early taste of Autumn.
