Severe Thunderstorm Warning 60, NWS New Orleans, LA

Area Forecast Discussion
National Weather Service New Orleans LA
347 AM CDT Wed Apr 29 2020

.SHORT TERM...
Will maintain high rain chances with showers and scattered
embedded storms along the front this morning. A few strong to
severe storms in this squall line are expected with hail and
strong to damaging wind gusts being the main factor but can not
rule out an isolated tornado. Showers and storms will linger
through much of the day as rainfall amounts of 1 to 2 inches can
be expected. Dry conditions are expected Thursday through the
weekend with warm conditions returning into the weekend and the
first of next week.

.LONG TERM...
Once all the unsettled weather passes through our area, rain stays
out of the forecast as high pressure will build in for the rest of
the weekend as a upper level ridge holds over most of the southern
CONUS. Return flow starting on Saturday will also steadily bring up
the dew points nearing 70s by Monday. Additionally, temperatures
will increase through the weekend with 90 degree days possible,
especially on Sunday and Monday.

&&

.AVIATION...
Cigs and TS activity will keep all terminals in IFR or LIFR
conditions through the morning hours. This will ease as the day
wears on and should be VFR by afternoon. This process will move
from north to south. Once VFR conditions move into each terminal,
it should stay that way through this taf cycle.

&&

.MARINE...
Winds will increase on this afternoon and tonight especially
behind the front as a moderate offshore flow once again returns to
the coastal waters. Offshore flow will continue on Thursday and
gradually lull by Thursday night remaining light but shifting
around to a southerly direction over the weekend.
