.SHORT TERM (Tonight through Sunday)...

Surface high pressure centered over the central Gulf coast region
will move east of the region tonight. The next shortwave trough will
move southeast through the central Gulf coast region late Friday and
Friday night with a weak surface wave or low pressure area moving
through the northwest/north central Gulf. Am expected generally
light to moderate rainfall amounts from mainly scattered showers
with this system Friday afternoon and Friday night with most of the
higher rainfall amounts in the 1/4 to 1/2 inch range. Saturday
should be dry with mostly sunny skies returning as surface high
pressure starts to build in from the northwest, and this clear/sunny
weather will continue into Sunday. Temperatures will remain chilly
tonight, but not as low as early this morning. Highs will be near
seasonal averages on Friday with highs near 70, then cool slightly
on Saturday with highs mostly in the mid to upper 60s. Saturday
night will be chilly again with lows in the upper 30s and 40s.

.LONG TERM (Monday through Thursday)...

Surface high pressure will remain in control with dry and mild
weather expected Monday. As the surface high shifts east, the
next system that may impact our region later in the week will be
a series of shortwave troughs that will start moving through the
California coast and Desert Southwest western states Tuesday
through Thursday. The central Gulf coast region should remain
mostly dry and under the influence of the western periphery of
surface high pressure and ridging aloft, although a few showers
could occur Wednesday and/or Thursday. Temperatures should be near
to slightly above seasonal averages Monday and Tuesday then even
warmer on Wednesday and Thursday.
