.PREV DISCUSSION... /issued 210 PM CST Sun Dec 16 2018/
Wx map shows 1026mb high over the region this afternoon. Satellite
showing stubborn low cloud clearing line across St. Martin, Iberia,
and St. Mary Parishes into the Gulf, with scattered mid to high
level clouds streaming over SE TX/LA. Temperatures this afternoon
rising into the mid 60s over SE TX/SW LA, lower 60s elsewhere
except for lower Acadiana in the lower to mid 50s due to the
lingering cloud cover.
With the light winds, patchy fog will be possible after midnight,
with patchy dense fog possible around the daybreak hours. Only
limiting factor will be how much mid level cloud cover lingers
Partly to mostly cloudy skies and slightly below normal
temperatures expected Monday and Tuesday as high pressure ridging
over the Midwest to the Gulf only slowly moves east.
By Tuesday night into Wednesday, the high will be east of the
region, with south to southeasterly return flow returning.
Another potent upper level trough will move across the region,
bringing the chance of precipitation. Not looking nearly the
precipitation maker the last two systems were, as the system is
expected to move quickly. Preliminary precip totals range
~0.50-0.75" for the event. Once the low moves east of the region,
colder air will return to the region, along with no precipitation
for Thursday- Sunday. A slow warming trend expected Saturday and
Light and variable winds can be expected, as high pressure settles
over the area. Winds will become east to southeast Monday and
Tuesday as the high moves east. Another surface low and upper
level trough will bring increased chances of showers Wednesday,
followed by a cold front to bring strong offshore flow once again
