With the passage of a cold front this morning, parts of the metro area saw a few quick-hitting showers to start the day. As the system moved to our south this afternoon, mostly sunny skies returned to the area, but the biggest impact of this front’s passage will be felt beginning tonight and continuing through Thursday as below-normal temperatures make an unusual stop in the Mid-South, at least considering the past few months!
With Canadian high pressure settling in from the north, the cooler temperatures will begin filtering in to the area under northeast winds this evening. Expect numbers in the mid 40s across most of the metro when you wake up Wednesday morning, with temperatures only rising into the mid 60s during the afternoon even under sunny skies.
However, as the high pressure area makes it closest approach to the region late Wednesday, and winds lighten, the setup will be in place for the coolest night in the Mid-South in about a month, as readings in the city of Memphis drop into the lower 40s by Thursday morning. Outlying areas of the metro will likely dip into the upper 30s. At this time, the threat for any frost looks to remain mostly north and east of the metro area with freezing conditions possible closer to the Tennessee River.

By that time, a slow moving cold front will finally begin to gain some momentum and head east toward the Mid-South, increasing our rain and thunderstorm chances for Monday night into Tuesday. It’s unclear at this point whether this system will bring any threat of severe weather to our area, but confidence is starting to increase in this period being the most active over the next week. More details will emerge as the week progresses on this system’s impacts to the Mid-South.
