for evening discussion.
Tweaked current hrly temp, dewpoint, and wind speed/direction
grids. Current temp trends in association with GFS lamp hrly
projected temp guidance values showing that overnight low
temps might be a few degrees warmer than previously forecasted.
Will see how actual temp trends progress over at least the next
couple of hours before updating. Otherwise, remainder of forecast
package continues to be on track.
00z taf discussion.
High pressure will keep VFR going through the next 24 hours at
bna, ckv, and mqy. One concern is some lower clouds that will
develop over csv Tuesday morning. These broken clouds are
expected to be above 3kft as indicated in the taf, but may be
briefly MVFR. Otherwise, all sites will have very light south-southeast winds
overnight, becoming S around 9kt with a few gusts around 16kt on
Tuesday as a dry cold front approaches.
