Area Forecast Discussion
National Weather Service Lake Charles LA
259 PM CDT Sun Aug 7 2022

.SHORT TERM [Tonight through Tuesday]...

Isolated to at times scattered thunderstorms finally started going
this afternoon. This will continue into the early evening hours
and dissipate during the overnight.

Guidance is still depicting an overall drier day on Monday as
heights continue to rise a bit across the area with increasing
capping.

Rain chances begin to tick up a bit for Tuesday with the approach
of an easterly wave and possibly some activity rolling in from the
north around a weaken ridge by Tuesday.

In addition did go ahead with the coastal flood advisory for
tomorrow morning as easterly winds continue. This may not be the
last advisory needed this week as easterlies are forecast to
increase through week with the easterly wave.

.LONG TERM [Wednesday through Sunday]...

The mid to upper level trough pattern will slowly transition to the
mid to upper level high building over the Western U.S. with a large
longwave trough deepening over the Eastern U.S. Across the Gulf, a
tropical wave will provide abundant Gulf moisture and lift to keep
much higher than normal shower and thunderstorm chances Wednesday
through Friday. As the wave axis moves across the region Thursday,
expect southerly winds 10-15 kts across the coastal waters, but
otherwise, expect around 10 kts for most of the extended forecast as
high pressure ridges across the Northern Gulf.

Lower precipitation chances expected by Saturday afternoon and
Sunday as the upper level ridge builds a little stronger from the
northwest and expected to limit the development of showers and
thunderstorms.

Afternoon highs expected to be somewhat lower Wednesday-Friday,
mainly in the upper 80s to lower 90s due to the increase cloud cover
and precipitation. By the weekend, slight uptick in the
temperatures, ranging from 90-95, with upper 90s across Inland
Southeast Texas. Low temperatures expected to be in the lower to mid
70s, with upper 70s to near 80 along the coast.

.MARINE...
