.DISCUSSION...
Unseasonably warm weather will continue into mid-week. This will
also occur with southerly winds continuing to bring in Gulf
moisture, keeping RH values high. Afternoon minimum relative
humidity values of around 60-65 percent are expected along the
coast with inland areas dropping closer to 50 percent over the
next several days. Chances of late night and early morning patchy
fog and low clouds will continue for the next several days as
well. Isolated showers and thunderstorms will be possible on
Wednesday, mainly in the Brazos Valley and Piney Woods region,
then increasing chances Thursday into Friday morning with the
passage of a cold front.
