NORTHEAST ACROSS THE SOUTHERN PLAINS FROM MID TO LATE WEEK.
SOUTHWEST FLOW ALOFT AHEAD OF THE DISTURBANCE COMBINED WITH
DEWPOINT VALUES IN THE UPPER 60S WILL ALLOW FOR A GENERALLY
UNSTABLE SETUP ACROSS THE ARKLATEX AHEAD OF THE APPROACHING

PRECIPITATION IS FORECAST TO INCREASE IN COVERAGE BEGINNING ON
WEDNESDAY EVENING AND CONTINUING INTO THE OVERNIGHT HOURS.
