Area Forecast Discussion
National Weather Service Lake Charles LA
1127 PM CDT Fri May 7 2021

DISCUSSION...
For 05/08/2021 06z TAF Issuance.

AVIATION...
Winds have relaxed at the terminals this evening, with some high
cirrus also continuing to filter through the region. Some lowered
VIS noted in metars at BPT, but surrounding obs and areal cams
suggest this is very localized. Still, could see some periodically
lowered VIS readings through the night given the light winds and a
bit more moisture. Otherwise, VFR conditions are expected to
prevail through the TAF period with light winds tonight becoming
gusty out of the south after sunrise.

.PREV DISCUSSION... /issued 928 PM CDT Fri May 7 2021/

DISCUSSION...
Wx map shows 1020mb sfc high over AL/MS with weak ridging across
the north central Gulf waters. Satellite imagery showing the
sct/bkn cirrus layer across the region, expected to thin out
overnight. Temperatures cooling off a bit, still ranging from the
mid 60s to mid 70s. Weak southeast flow has returned across SE
TX/S LA with the slightly higher dewpts in the lower 60s. Across
C LA, winds are calm with dewpts in the mid 50s. Thus, expect the
coolest morning lows in the upper 50s/near 60, with lower to mid
60 elsewhere. Ongoing forecast looks on track with no updates
needed at this time.

PREV DISCUSSION... /issued 403 PM CDT Fri May 7 2021/

DISCUSSION...

SHORT TERM (Today through Saturday night)...

It's hard to ask for weather more pleasant than today. High
pressure nearly overhead is yielding abundant sunshine, light
northerly winds and temperatures in the lower 80s. The high will
shift east of the region overnight turning surface winds out of
the southeast which will allow dewpoints to begin creeping back
up. The tightening pressure gradient between the departing high
and a deepening low over northern Oklahoma will accelerate the
moisture return and result in breezy conditions by tomorrow
afternoon.

LONG TERM (Sunday through Friday)...
An active weather pattern is expected for a majority of the long
term with POPs being introduced starting on Sunday and extending to
the end of next week. By tomorrow southerly flow will return,
enhancing moisture advection across the area. This will prime our
area ahead of the first frontal system set to reach our area late
Sunday into early Monday. The front will slow then stall along the
gulf coast states. Sunday and Monday the models project a bulk of
the precipitation falling in our northern zones, then spreading
south. WPC D3 ERO has the northern fringe of Rapides Parish in a
marginal risk, however most of the precip is expected to the north
of us. SPC D3 SWO has a majority of the CWA in a marginal risk for
severe thunderstorms, with a slight risk clipping the northern
fringe of our SETX Counties and CenLA Parishes. Forecast soundings
support the possibility of large hail and damaging wind gusts mainly
along the line from ETX to AR.

Early to mid next week, a trough will move southeast into the
region. The potential for flooding is not a major concern, but it
will be monitored for this period. Over the northern Counties and
Parishes up to an inch of rain is forecasted ahead of this trough
while up to three inches is expected as the trough moves through. By
the end of next week, this activity is set to clear the area, being
replaced by a surface high pressure system building in and keeping
us dry for the duration of the forecast period.

MARINE...
Small craft exercise caution may be needed tomorrow afternoon as a tightening
pressure gradient between high pressure to the east and a
deepening low over northern Oklahoma will result in elevated
onshore flow.
