DISCUSSION
WELL DEFINED SEA BREEZE OUTFLOW BOUNDARY IS MOVING NORTHWARD NEAR
20 MPH FROM SE TX/SW LA. LAPSE DATA SHOWING ATMOSPHERE BECOMING
UNSTABLE UP NEAR THE I-20 CORRIDOR AND WITH PLENTY OF PRECIPITABLE
WATER AVAILABLE ON OUR MORNING SOUNDING...SEE NO REASON WHY THIS
ACTIVITY WILL NOT HOLD TOGETHER AND INCREASE IN AREAL COVERAGE AND
INTENSITY THIS AFTERNOON. THEREFORE HAVE BEEFED POPS UPWARD ACROSS
MUCH OF OUR SOUTHWEST ZONES THROUGH THE REMAINDER OF TODAY AND
INTO THE EVENING HOURS. HAVING SAID THIS...ALSO LOWERED MAX TEMPS
A FEW DEGREES ALONG THE I-20 CORRIDOR OF NE TX BUT ESPECIALLY
ACROSS THE LOWER TOLEDO BEND AND SAM RAYBURN COUNTRY OF DEEP EAST
TEXAS. UPDATE WILL BE OUT SHORTLY.

AVIATION
LOOKS LIKE VFR WILL BE THE PREDOMINANT FLIGHT CATEGORY AT MOST
TERMINALS THROUGH 25/1800 UTC. SIMILAR TO THE PAST COUPLE OF
MORNINGS...CIGS/VSBYS WILL LIKELY REDUCE FLIGHT CATEGORIES TO IFR AT
KLFK AND KMLU AROUND 25/1200 UTC BEFORE MIXING OUT MID-MORNING.
CONVECTIVE COVERAGE THIS AFTERNOON SHOULD PRIMARILY BE CONFINED
TO AREAS SW OF KTYR- KLFK. AS SUCH...I WILL ONLY MENTION TSRA
ACROSS MY E TX TERMINALS FOR THE TIME BEING. /BUTTS/
