Area Forecast Discussion
National Weather Service Lake Charles LA
357 PM CDT Fri Jun 4 2021
.DISCUSSION...
.SHORT TERM (Today through 12Z Sunday)... Showers and
thunderstorms continue to form mostly offshore and along the coast
in western portions of our area with northward movement. Chances
for additional development will diminish around sunset with
remaining storms eventually moving out of the area or dissipating.
Mostly cloudy skies will persist through the entire period. Winds
will shift from easterly to southeasterly overnight and increase
during the morning hours on Saturday.
Patchy fog will be possible Saturday morning for Central LA.
Showers and thunderstorms will be expected to move onshore during
the early morning hours. Additional development of storms will
also be expected near the coast, expanding inland as the day
progresses. However, with the possibility of larger complexes
moving onshore early in the morning, the additional cloud cover
could inhibit further development later in the day on Saturday.
Chances for showers and thunderstorms will continue Saturday
evening into Sunday morning.
The significant cloud cover and storms over the weekend will help
to keep temperatures below average, with highs in the low 80s and
lows in the low 70s.
A Flood Watch is in effect through Sunday evening. The storms
expected over the weekend in combination with the already
saturated ground from the much above average rainfall over the
past several weeks means that flooding will be possible. Rainfall
accumulations over the weekend will be 2 to 5 inches with locally
higher amounts.
55
.LONG TERM (12Z Sunday through Day 8)...
The active weather pattern will continue through mid next week.
While most of the activity will be diurnally driven, a larger
synoptic scale feature will boost higher QPF amounts.
Deep layer flow along with an upper level cutoff low will bring
about a multi day rainfall event for the region. The aforementioned
cutoff low is currently over TX and will slowly drift NE today into
Saturday. Sunday and Monday will see the most rainfall with 1.0 to
2.5 inches expected with locally higher amounts. Due to the soil
saturation percentage remaining high (thanks to the minimal breaks
from rain), flash flooding is a concern. A Flood Watch is in effect
from today until Sunday evening, however this could be extended. By
mid next week the system will weaken and move further north. This
will lighten but not end rainfall expected for our area, as activity
will become diurnally driven again.

1 funnel cloud. Local standard time, as filed.
Several photos were taken of a funnel cloud near the north end of Calcasieu Lake. The photos left uncertainties if the funnel became a landspout or waterspout since the horizon could not be seen.
