.AVIATION...More ideal weather for takeoffs and landings across
the Rio Grande Valley terminals right into Wednesday. The only
possible fly in the ointment could be a brief period of high MVFR
ceilings toward daybreak Tuesday, given a continued gradual
increase in surface moisture as well as decent moisture between
925 and 850 mb. That said, not seeing enough of a signal to
introduce at this point...so instead have left sky cover as
scattered. Could also see periodic cirrus plumes (high VFR) though
latest satellite has the thicker plumes well to our north, and
layered RH forecasts show gradual decreases in moisture overnight
and into early Wednesday as upper level ridge expands from the
western Gulf back into south and central Texas. 

Otherwise, the usual afternoon pickup in east-southeast winds but
still less than 15 knots...diminishing below 5 knots between 9 and
11 PM before returning just below 10 knots after 10 AM Wednesday.
Not expecting any fog at this point despite slight rises in
dewpoints and still light winds with longer night...can't rule it
out completely at Harlingen/Valley but appears any weekend surface
moisture has largely dried up.
