New SHORT TERM, LONG TERM, MARINE
SHORT TERM
(Tonight through Thursday night)
Issued at 1153 PM CDT Tue Jul 8 2025
Temperatures continue to be near average as the northern Gulf Coast remains sandwiched between what seem like semipermanent ridges over the SW CONUS and Western Atlantic. The weakness between these two ridges has allowed for nearly continuous shortwave troughs to ride the periphery of the SW CONUS ridge and get stuck over the Mississippi River Valley for the past month or so, and there is no indication that this longwave pattern will be going away just yet. No complaints here honestly.
Our next weak shortwave trough is currently over the upper Mississippi River Valley and will work its way southeastward through the day today, slow down as it gets stuck in between the ridges on either side of it, and begin to lose its coherence. A key development in the trends with this trough appear to be that it is losing its coherence much quicker in latest guidance and does not appear to be providing as much atmosphere lift as what was advertised in forecasts from prior days. As such, while PoPs will be elevated compared to climatological norms, we have seen NBM guidance correct lower closer to 50-60% today. Although there is some uncertainty in overall coverage of storms, confidence is higher that the lake and sea breezes will be the focus for storm initiation along the I-10/12 corridor by just after noon. PWAT values have increased since the prior days as well with the 00Z LIX sounding observing a 1.89" PWAT value which lands around the 75th percentile for this time of year. Thus a few of the stronger storms today will have more moisture to work with and carry higher rainfall rates that could lead to street flooding especially in poor drainage and urban areas along the I-10/12 corridor.
By Thursday, the weak shortwave troughing will be situated just to the north of the CWA and with deep moisture across the area (PWAT values nearing 2"). This should lead to a more appreciable increase in convective coverage with storms becoming more numerous through the afternoon hours. While widespread heavy rain is not forecast, individual storms will be capable of producing high rainfall rates exceeding 3 inches per hour that can cause quick accumulations and overwhelm street drainage systems. There is notable disagreement amongst guidance on where the greatest focus of storm coverage will be on Thursday with general agreement only development along the lake and seabreezes, as typical of summer afternoons. NBM guidance continues to want to focus highest PoPs along the Louisiana Coast, but CAM and SREF guidance is emphasizing higher PoPs closer to the weak shortwave trough axis over ArkLaMiss. Therefore, PoPs have been nudged upward in a blend with this guidance over southwest Mississippi, Florida Parishes, and coastal Mississippi. Regardless, despite the higher PoPs, it's probable that Thursday will not be a complete washout for most locations.
LONG TERM
(Friday night through Tuesday night)
Issued at 1153 PM CDT Tue Jul 8 2025
The shortwave troughing will linger into Friday and Saturday in the weakness between ridges so afternoon PoPs will remain elevated higher than climatological norms, but coverage will continue to be weighted northward closer to the trough axis.
By the end of the weekend, we'll gradually see the western periphery of the Atlantic ridge nudge itself westward and split off over the northern Gulf. This could allow temperatures to get closer to the mid to upper 90s by Sunday and Monday. Heat indices could push closer to 110F though these heat indices may not be prolonged before rain-cooled air from afternoon storms knock temperatures down.
By midweek next week, long-range ensemble guidance is suggesting we could see another piece of the central Atlantic TUTT splitting off and backing underneath the Atlantic ridge and into the southeastern CONUS, similar to what we just saw this past weekend. If this comes to fruition, the ridging overhead would not last long before we see yet another enhanced period of afternoon storm coverage.
AVIATION
(00Z TAFS)
Issued at 655 PM CDT Tue Jul 8 2025
VFR conditions are prevailing at all terminals with only a few towering cu noted on visible satellite in SW Mississippi and adjacent LA Parishes. Any lingering cu will dissipate after sunset with near calm or light southwest winds prevailing overnight. No fog impacts are expected on Wednesday morning.
PROB30s have been introduced at all terminals with respective timings to reflect isolated to scattered TSRA impacts moving from west to east across the area through the afternoon hours. A few of these storms could be strong and produce wind gusts upwards of 30 to 40 knots with short-lived LIFR conditions.
MARINE
Issued at 1153 PM CDT Tue Jul 8 2025
Marine conditions will be benign through the period outside of any localized impacts from convection. Winds will remain between 5 to 15 knots out of the south to southwest in an onshore direction through the work week. A fairly typical summertime convective pattern is expected with showers and storms developing during the late night, peaking during the morning hours, and diminishing through the afternoon and evening. Storm coverage over the waters will increase in coverage during the morning hours each morning starting Wednesday into the weekend with widespread storms most likely on Thursday.
