.PREV DISCUSSION... /issued 1015 PM CDT Sun Jul 23 2017/

DISCUSSION...
A convective complex is moving southward across the Red River
from Oklahoma and Southwest Arkansas into North Texas. These
storms have had a history of severe wind gusts, as measured by
KPRX and the Oklahoma Mesonet site at Hugo, OK. They have also
been efficient rainfall producers. We have received reports of
nearly 3 inches of rain in portions of McCurtain County this
evening. Radar loops indicate a weakening trend over the last few
hours in the segment of the line along Interstate 30 between the
DFW Metroplex and Texarkana. Latest mesoanalysis suggests that
convective inhibition increases with southward extent in East
Texas. Convection earlier this afternoon has largely stabilized
the atmosphere along and south of Interstate 20. Therefore,
continued weakening of this thunderstorm cluster is expected.
However, some additional development cannot be completely ruled
out by an outflow boundary surging outward away from the storms.
PoPs were updated to account for the latest trends with this line
through 06z.

Several locations have already reached their low temperatures for
tonight due to the effects of rain cooled air from a few hours
earlier. These locations may actually see temperatures rise a few
degrees during the overnight hours as dewpoints recover. Patchy
fog cannot be ruled out, especially where heavy rain fell earlier
today.
