I don't know if the most recent LIX update has been posted yet, so here it is:
National Weather Service New Orleans LA
823 PM CST Thu Jan 20 2022
.EVENING UPDATE...No major changes made to the forecast. Still
looks like a good chance of seeing some minor frozen
precipitation. Power outages and tree damage are not expected but
it would not be out of the question to see ice accumulation just
under 0.1" in a few locations. So where is that going to occur if
it does, well there are two locations.
First area which will be around the area that the heaviest precip
is expected and that is in a southwest to northeast line between
BTR and Thibodaux and towards Slidell and possibly coastal MS.
Second area could be a good bit north where we weren`t
anticipating much precip, this area possibly just south of the
LA/MS border in the Florida parishes. The reason for this is we
are currently watching a line of showers across southeast TX
moving to the east. Previous days it was expected that any precip
moving out of southeast TX would dissipate but looking at the
radar and especially satellite this is looking less likely to
completely dissipate. This area is also running the coldest
currently in our CWA so there wouldn`t be any wasting of rain as
that area cools to freezing.
Overall looking at the WV there is a lot of lit moving right over
the region. There was some concern that it may be suppressed a
little south along with the moisture but currently looking that
doesn`t appear to be the case. South LA and southern MS are both
under the influence of the RRQ of the jet. This appears to be
helping the convection as cooler cloud tops continue to stream in
from the west and southwest. Radar is also showing echo return
becoming a little more enhanced and moving in. Given our 00z sndg
we still have some of the mid-levels to moisten up but the bottom
5k ft is already 90-100% saturated. We will send up another
balloon shortly and see how much the column has changed and send
another up around midnight. /CAB/
