.AVIATION...
IR Imagery this morning shows 4-6kft moisture developing across
the I-20 corridor of NE TX into portions of NW LA and SW AR. This
moisture currently effecting the TYR/GGG/TXK and SHV terminals.
Elsewhere, just high clouds were noted at the ELD/MLU and LFK
terminals. For the 12z TAF cycle, should see VFR conditions
throughout the day into the overnight hours. Cannot rule out brief
MVFR ceilings and or VSBY restrictions for a couple hours this
morning at the LFK terminal. 4-6kft ceilings should scatter out by
late morning into the afternoon hours. Isolated -TSRA will also be
possible mainly at the LFK/TYR terminals today but coverage will
be too limited to mention in this package. Look for E to ESE winds
today mainly less than 10kts becoming light overnight.

DISCUSSION...
WV imagery this morning shows upper ridge axis over the Mountain
West, with upper trof over the ern CONUS. Our region under weak
but disturbed nwly flow aloft. Disturbance along the TX Gulf Coast
providing shwrs/tstms along the coastline, and these are expected
to gradually increase as the disturbance cuts off and drifts ewd
through midweek. As a result, we will see gradually increasing
coverage of shwrs/tstms, especially during peak heating, through
Thursday.

Another trof/cold front will begin to sag swd into our
region Friday, and looks to bring some better coverage of
convection for areas along and n of I-20 through Sunday. Rain
chances to diminish Tuesday, as trof departs to the e and the
upper ridge begins to nose into TX.

Overall, temps to remain slightly below seasonal normals due to
present soil moisture and the possibility for convection most
days. However, trends for day 7 and beyond show the ridge
migrating ewd, which may signal the arrival of more typical
ArkLaTex summertime temperatures. /12/
