...New AVIATION...

.UPDATE...
Issued at 1127 AM CDT Sun Jun 1 2025

A small area of convection over portions of ECntrl TX has been
showing trends of trying to wind down late this morning, as it has
encountered slightly drier air and reduced instability given the
N-S gradient in isodrosotherms and lower mixing ratios evident
bisecting E TX. In fact, the latest few volume scans of the mosaic
radar has shown a tendency with the isolated strong storm over
Ern Henderson County to take a more Srn track along this
gradient, towards the slightly better instability air noted just
to its S. The latest sfc and visible satellite analysis reveals
an associated outflow bndry that has pushed S along the leading
edge of this storm W to Ern Ellis County, although post-bndry
winds upstream have already begun to recover/take on a more SErly
direction suggesting that the bndry is shallow. This was not
before an impressive shelf cloud showing from this storm over Van
Zandt County (near Canton) earlier before the storm began to
weaken.

This lead outflow bndry will likely serve as focus for additional
scattered convection as we move through the afternoon, as the air
mass ahead of it continues to destabilize in response to
increasing theta-e ridging out ahead of it, as well as the
approach of weak forcing aloft associated with the weak NW to SE
shortwave trough axis noted from the Mid Red River Valley into
portions of extreme NE TX to along the AR/LA border. Given the
ongoing trends as well as some of the latest 12Z HREF guidance,
have increased pops a bit to mid chance through the afternoon across
the Wrn sections of E TX, while also extending slight chance pops
back farther E into extreme Ern TX/Wrn LA given the current radar
and guidance trends. Have also beefed up the sky grids to reflect
mostly cloudy wording across much of the region given the
extensive elevated cigs developing along/ahead of the
convection/trough axis. This in turn, may affect max temps
especially over portions of E TX/SW AR, and thus, have lowered the
forecast values slightly given the ongoing -RA as well as the
cooler 15-16Z temps. Believe that any isolated severe threat will
be later this afternoon over the far SW sections of E TX, before
shifting to the S by early to mid evening.

Zone update already out...grids should already be available.
