Area Forecast Discussion

.DISCUSSION...
Area remains under a flat ridge along the northern Gulf coast
today. Thus making for another tricky convective forecast. At this
time expect bulk of the convection will remain to the north of the
forecast area, however with moist unstable air will can not rule
out some activity along any outflow boundaries from the north.
This would mainly be during or shortly after peak heating and
along the northern and eastern portions of the forecast area.

Also inherited a heat advisory. This mornings guidance is not a
bullish on heat index values getting up to criteria, especially in
the potential convection and it appears to show drier air mixing
down at the other locations. However the past few days dewpoints
have stayed up a little more than expected and thus will continue
the heat advisory for now most areas. Did add Tyler county and
removed the eastern fringe.

Otherwise the ridge weakens just a bit for the weekend and thus
will increase pops just a bit but not as high as the previous
forecast.

Then late weekend into early next week still see and inverted
trof moving across the gulf will cause an uptick in clouds and
showers early next week. This may hinder eclipse viewing for our
area especially along the coastal zone.

This trof will move inland around mid week, however daily rain
chances will continue.
