Area Forecast Discussion
National Weather Service Lake Charles LA
316 PM CDT Sat May 29 2021

.DISCUSSION...
With a cold front in our vicinity, we had a band of thunderstorms
pop up suddenly and cause some flash flooding and small hail in
the Lake Charles area. This activity will weaken as we get closer
to sunset, but in the meantime outflow boundaries are expanding
towards southeast Texas and central Louisiana, so there could be
more flash flood warnings in those regions if the boundaries cause
more storms to develop.

We should stay dry Sunday through Tuesday, so good weather for
outdoor activities for Memorial Day, as the cold front is pushed
out in the Gulf by high pressure to our north. By Wednesday, the
high shifts further east, which will return us to a more typical
summer pattern of daily scattered showers and thunderstorms. This
will extend through the end of the week into next weekend.

As for temperatures, a little cooler than normal in store for
tonight and maybe Sunday night, before the warming trend for
nighttime lows through the rest of next week. High temperatures
will be influenced by the weather of the day. Early next week
with no rain, highs will be in the upper 80s, near 90. Wednesday
on it will likely drop to the mid 80s.
