9/29 – The Chief’s “Sunny & VERY Nice” Friday Morning Forecast

The main story remains to be a weak inverted trough situated over the northern Gulf just south of a weakening stationary front. This continues to supply persistent easterly flow as we’ve seen for a couple of days now, with a distinct separation of deeper Gulf moisture over coastal Mississippi and adjacent marine areas. Models pinpoint enough moisture above a well-mixed layer to support showers, but is situated below strong low to mid- level compressional warming/subsidence helping to keep a lid on further inland activity. Like yesterday, there is a decrease in rain chances to include mainly this morning at 20%.

Otherwise, persistent easterly flow has also led to minor coastal flooding corners for east-facing shorelines from water piling and somewhat across coastal Hancock County. Otherwise, tides come down some Friday and Saturday but may perk back up again Sunday/Monday, so I will be keeping an eye on that.

Quiet tonight as the focus shifts into a well-defined high-pressure system taking shape over the MS valley region. This brings the confidence of building heat this weekend. Something to be aware of with such strong high pressure and large-scale subsidence, this will suppress daily convective activity over land areas, to mainly isolated activity today-Sunday for each morning across warmer shelf waters. Otherwise, no major impacts going through Sunday.
