.DISCUSSION...
VERY DIFFUSE FRONTAL BOUNDARY FROM LUFKIN TO NATCHITOCHES AND
NORTHEASTWARD TOWARD WINNFIELD AND CLARKS BEGINNING TO SERVE AS THE
FOCUS FOR CONVECTION ACROSS POTIONS OF DEEP EAST TEXAS. EXPECTING
THIS CONVECTION TO CONTINUE TO SPREAD EAST ALONG THE BOUNDARY
THROUGHOUT THE MORNING AND INTO THE AFTERNOON AS AN UPPER-LEVEL
TROUGH ACROSS CENTRAL TEXAS SLIDES EAST. COULD SEE LOCALLY HEAVY
RAINFALL AND FREQUENT LIGHTNING WITH SOME OF THESE STORMS. MOST OF
THIS CONVECTION SHOULD BE LIMITED TO AREAS MAINLY SOUTH OF
INTERSTATE 20. HIGH TEMPERATURES TODAY TO CLIMB TO AROUND 90 DEGREES
AREAWIDE...WITH COOLER READINGS ACROSS NORTH CENTRAL AND NORTHEAST
LOUISIANA WHERE CLOUDS AND RAINFALL WILL BE MORE ABUNDANT.

DENSE FOG EXPECTED ACROSS MUCH OF THE REGION THROUGH MID-MORNING
IN RESPONSE TO SATURATED SOILS FROM PREVIOUS RAINFALL...LIGHT
WINDS...AND SOME SURFACE BASED INSTABILITY IN THE VICINITY OF THE
COLD FRONT. WILL GO AHEAD AND ISSUE A DENSE FOG ADVISORY AT THIS
TIME BASED ON CURRENT OBSERVATIONS FROM ACROSS THE REGION.

UPPER-RIDGE ACROSS MEXICO TO BUILD EASTWARD TOWARD THE ARKLATEX
TONIGHT. THIS WILL ALLOW FOR WARMER AND DRIER CONDITIONS AREAWIDE
THROUGHOUT MUCH OF THE FORECAST PERIOD. HOWEVER...BECAUSE THE
ARKLATEX WILL REMAIN ON THE EASTERN PERIPHERY OF THE RIDGE...WITH
AN UPPER-TROUGH SITUATED ACROSS THE SOUTHEASTERN UNITED
STATES...ISOLATED AFTERNOON SHOWERS AND THUNDERSTORMS CAN BE
EXPECTED ACROSS PARTS OF THE REGION EACH DAY. /05/
