Short term...today through Thursday...the weather pattern over the
next few days will keep the arklamiss mostly warm and dry. A ridge of
high pressure over the southern Mississippi Valley continues to
translate westward this afternoon and should center over the High
Plains by Thursday. This will allow a shortwave trough over the East
Coast to deepen and draw what is currently tropical depression 9
northeastward towards Florida. The northerly flow aloft on the
western side of this trough will help steer a weak cold front into
our region possibly late Thursday. Only a very low chance for showers
or thunderstorms over the next few days due to drier air in place.
Enough heating and surface moisture could still support isolated
light showers or a storm around the region, as has occurred again
this afternoon for parts of the arklamiss./Nf/

Long term...Friday through Tuesday...in the wake of the weak cold
front, low temps in the upper 60s to low 70s on Saturday morning
will probably represent the coolest morning (though these are within
a few degrees of normal for this time of year. More notably,
dewpoints in the 60s will be more common over the weekend. The
upper-level ridge will build eastward once again Friday and into the
weekend, with a general model consensus placing the core of the ridge
over MS/Alabama for the early part of next week. This will continue to
limit precip chances for the arklamiss except for areas closer to the
Gulf Coast. With the ridge overhead, we can also expect temps to
stay a few degrees above normal and heat index values generally
around 100 early next week. Labor Day looks to have seasonal weather
- highs near 90 and slight chance to chance pops focused towards
southern Mississippi and northeast Louisiana./Nf/

Aviation...VFR conditions will prevail through the period. Isolated
rain showers/thunderstorms and rain could briefly impact sites this afternoon. Patchy MVFR
conditions in fog will develop at glh after 31/11z and linger until
31/13z./26/
