Cold front to bring chance of severe storms, then drier air

A potent cold front is poised to move into the metro Sunday night. This front should have enough upper level support to move all the way through the area into central MS by Tuesday. That will mean a welcome change to our weather pattern – one that features less humid air and slightly cooler temperatures, especially in the mornings – for a good part of next week beginning on Tuesday.

However, the front will be moving into an airmass that has featured very humid air, hot temperatures, and plenty of instability.  That will mean a good chance that we’ll see thunderstorms ahead of it, which will occur during the day and evening Sunday.  In fact, there will be atmospheric factors in play that will provide the ingredients for the possibility of some severe storms on Sunday.  As typical for severe storms in the summertime, the main threats will be from damaging wind and perhaps some large hail, in addition to dangerous lightning.  Due to the abundance of moisture/humidity in place, some storms could also bring heavy rain in short periods of time.

Slight Risk of severe weather, per the Storm Prediction Center, for Sunday

The one potential “fly in the ointment” tomorrow will be presented early, as some showers or thunderstorms could form in the morning hours.  If this happens, it could sap some of the energy and instability needed to get severe weather later in the day. Overall MWN is expecting a chance of rain in the morning, probably after 9am, followed by a better chance (50%) of thunderstorms in the mid afternoon through evening hours (i.e., 3-9pm).  We’ll be monitoring things throughout the day and have nowcasting coverage on Facebook and Twitter (see links below) anytime severe weather is a possibility.
