.DISCUSSION...
Consistent showers this summer have put a lid on fire weather,
with no parts of our region in official drought or even D-0
condition. This week will see a dry pattern with clear skies; in
addition, minimum RH values in the afternoon will be around 40%
for central Louisiana and interior portions of southeast Texas.
Weak winds will be the main limiting factor, with wind gusts
staying below 10 mph through the end of the week.
