Discussion
A strong cold front will approach the region later today and bring with it isolated morning showers and thunderstorms and likely a round or two of afternoon and evening showers and thunderstorms. Any PM thunderstorm can be strong-to-severe with heavy rainfall and potential localized flash flooding. The front drops southeast of here on Friday, but a residual shower or thunderstorm cannot be ruled out and the end of the work week will continue to feature quite warm conditions. Elsewhere, intensification was slow overnight in a tropical system now over the Gulf of Mexico, but that should become more rapid over the next 24 hours. As such, it is likely this system will reach named tropical storm status later today or tonight (to be called Barry) and it could reach hurricane status by the weekend. It appears this system will drift west for much of today and then take a turn to the north-to-northwest by the weekend and perhaps end up making landfall in central Louisiana. Tremendous rainfall amounts are likely with “Barry” in the central Gulf coast region; especially, over southern Louisiana where more than a foot can fall over the next couple of days and the Mississippi River is already running at high levels from springtime rains and snow melt. Looking ahead, it is possible that the remains of Barry has an impact here in a week or so as it potentially takes a track from the southern states into the Mid-Atlantic region.
