SHORT TERM
(This evening through Thursday)
Issued at 307 PM CDT Mon Jun 24 2024

Just walk outside and yep you will know the forecast. It`s Summer, hot, muggy, daily rain chances, and just downright oppressive conditions. This afternoon temps rose into the lower to mid 90s across the entire region and with dewpoints in the 70s this easily led to heat index values in the 100s with most sites sitting between 104 and 110. A line of convection that was moving through central MS/AL earlier this morning finally began to approach the area this afternoon however most of it weakened with widely scattered storms along the old outflow boundary and the greatest concentration of storms over portions of coastal MS.
Heading into this evening isolated to widely scattered storms will continue for an hour or two but most activity should quickly dissipate over the land and become more marine focused.

Over the next few days look for rather similar conditions with the one aspect of slightly increasing rain chances especially by Wednesday and into Thursday. The ridge that has been retrograding should become centered over the four corners by Tuesday and then begin to amplify. In response we will see troughing over the eastern CONUS and this will send a s/w south through the Mid MS Valley and into the Lower MS Valley late Wednesday. By Thursday this s/w will really slow down and become trapped along the coast and into the northern Gulf while the ridge axis on the east side tries to build back to the east over top of it. This should lead to much better rain chances Wednesday and Thursday with Wednesday having the biggest question mark mainly due to timing.

Tuesday will likely be almost a carbon copy of today except likely a little more oppressive. Ridge will still be firmly in control with h925 temps around 27-28C leading to highs in the same ball park as today. The biggest difference is going to be higher humidity values as LL moisture continues to increase along with whatever rain falls over in the next few hours. With highs in the mid to upper 90s again and likely higher humidity values in the BL, heat index values will be a touch higher than they were today. With that we have issued another heat advisory for the same area.

Wednesday and Thursday we will continue to see oppressive conditions but the saving grace could be scattered to numerous showers and thunderstorms. Again Wednesday seems to be the biggest question mark as timing could be the issue. Main issue is the energy coming out of the PAC over the Washington and British Columbia. This impulse should begin to surge southeast out of the High Plains Tuesday evening across the Plains and into the Mid MS Valley by Wednesday morning. If it is this fast and can begin to move into the Lower MS Valley around midday then there will be a good chance of decent coverage of storms by mid/late afternoon. That said we will be under northwest to northerly flow and remember this typically leads to convection beginning much later in the day and that would allow the region to warm up again along with another heat advisory likely.
Thursday we will have the impulse or remnants of it sitting right over top of us and this should allow for convection to develop rather quickly. This would keep highs down a few degrees and thud the oppressive conditions to slack off some. /CAB/

LONG TERM
(Thursday night through Sunday night)
Issued at 307 PM CDT Mon Jun 24 2024

Going into Friday and the weekend, upper level ridging is expected to build back into the area. Despite some weak subsidence aloft associated with the high, there should still be enough moisture in place to support scattered diurnal showers and thunderstorms. In fact the latest run of the GFS indicates PW values could still be hovering near or just under 2 inches through the latter part of the week and weekend, which puts the value above the 75th percentile for this time of year.

Expect to see daily showers and thunderstorms with the typical summertime diurnal max in the mid to late afternoon, diminishing in the early evening. Temperatures will be running above normal, and the aforementioned ample moisture may bump the afternoon heat index values above advisory criteria, but we`ve got time to monitor those trends. DM/95

AVIATION
(06Z TAFS)
Issued at 1132 PM CDT Mon Jun 24 2024

VFR conditions will prevail at all terminals through the overnight hours. Some MVFR VIS has been noted at MCB again, but low confidence beyond some bounces in VIS. Introduced VCTS and PROB30 groups to tomorrow afternoon with highest chance of impacts to terminals being 18-21 UTC for immediate coastal areas and beyond 20 UTC along and north of I-10/12. Storms will be capabale of strong gusty winds varying from prevailing winds and substantial drops in VIS/CIG.

MARINE
Issued at 307 PM CDT Mon Jun 24 2024

High pressure continues to dominate the coastal waters with light onshore flow which will continue through midweek. A front will move toward the region mid week to late in the week before washing out which will help keep the pressure gradient on the lower side. Only time winds may pick up would be overnight east of the MS delta during the typical diurnal increase during the Summer. Otherwise, convection will be possible especially during the overnight, which could locally increase winds and seas. /CAB/
