.DISCUSSION...
Issued at 105 PM CDT Mon Sep 8 2025
Comfortable conditions (by early September standards) indicative
of our "False Fall" are evident in the sfc obs as of 17-18Z, with
temps having climbed into the upper 70s/near 80, with much drier
air which has spilled SSW in wake of our weekend cool fropa
resulting in the edge being taken off in the humidity as dewpoints
have fallen off into the lower/mid 50s. Sfc ridging extending from
the Midwest SW into ECntrl TX will persist tonight through much of
Tuesday, with light winds/some thin high clouds sinking SE still
resulting in good radiational cooling across the region tonight.
In fact, temps tonight will be the coolest since what was observed
in mid-May, with readings falling into the 50s over much of the
region. Unfortunately, this will be short-lived as the sfc ridge
begins to drift farther E Tuesday, with the low level flow
becoming more E which will tap the more humid air evident over
Cntrl/Srn AL this afternoon and advect it W into portions of the
Lower MS Valley as early as Tuesday afternoon. This will also
result in more of a cu field that will advect W as well, some of
which may spill into portions of NE LA Tuesday afternoon.
Flat upper ridging noted on the water vapor imagery over the
Desert SW is progged to expand E and begin to amplify Tuesday from
Far W TX N to the leeside of the Rockies, drifting E into the Nrn
Plains S into W TX Wednesday. Increased subsidence beneath the
ridge and the low level moisture advection from the E will allow
for a "change in the seasons" with the start of our "Second
Summer" with the return of above normal temps over much of the
area by Thursday as they climb back into the mid 90s.
Unfortunately, little if any change in the synoptic pattern is
progged amongst the various ensembles as upper ridging will remain
firmly entrenched and stagnant from the Srn Plains/Lower MS
Valley into at least the Mid-South region through this next
weekend into at least the first half of next week. Thus, dry
conditions will continue through the period, with the tropics
expected to remain quiet as well.
