Area Forecast Discussion National Weather Service New Orleans LA 255 AM CDT Thu Apr 2 2020

SHORT TERM. It has been a quiet and generally cool night. by 07z most of the area had already fallen into the 50s. The few locations that hadn't yet were in the lower 60s while a few other locations were in the lower 50s on their way to the upper 40s.

Nothing much really to talk about today. We will see LL temps begin to slowly moderate with h925 temps around 14/15C which should easily yield highs in the mid 70s with a few upper 70s around the region. Forecast issue comes this evening and tonight as a noticeable jet streak moves across the region. At 8z this feature is seen on WV moving over the Sierra Madre into the Big Bend region of TX. Even with this feature moving overhead tonight it just doesn't appear we will moisten up enough to get much to develop. PWs from last nights sndg were only 0.65" and this was lower than what the GFS initialized with. Will keep the forecast dry for tonight. This agrees with all of the latest guidance as well.

As for rain potential Friday and Friday night this doesn't really look that good either. Our jet streak will move east-southeast of the region while we move under the base of a highly amplified yet squeezed ridge. The airmass will continue to struggle to recover which may not finally occur till Friday night. Combine that with no real lift (maybe even subsidence aloft) and possibly the only positive for rain would be daytime heating and possibly weak seabreeze support. With that will keep the forecast dry for Friday and Friday night however, we may actually see rain trying to nudge in from the west early Saturday morning.

Saturday rain chances look a little better but not great. The ridge over the CONUS will begin to slide to the east and this may allow a little better mid level support to move in. The slight lowering of hghts in combination with deeper moisture along with whatever convection to our west is out there should allow for a few shra to push into the area. Rain chance still don't look great heading into the night and Sunday as ridging over the western Gulf could build across the area driving what ever disturbances coming from the Pac to our north thus keeping us dry. /CAB/

LONG TERM. /Sunday through Wednesday/ Fringe affects of a Canadian airmass will be in place over the Gulf States Sunday with easterly flow veering to onshore return flow Monday. Slow evolving central Plains cyclogenesis bottles much of the baroclinicity well north of the forecast area but a weak trough may settle into the area to bring a chance of showers and thunderstorms Wednesday and Thursday ahead of a stronger frontal boundary, along with influences from what should be a better gulf breeze regime by middle of next week. Temperatures should be quite warm during the extended portion with Tuesday and Wednesday possibly challenging 90F in a few locations. Morning lows will start near normal levels but warm with increasing humidity middle of the week. 24/RR

AVIATION. Pretty quiet on the aviation front. For the next 24 to 30 hours all sites should remain in VFR status. /CAB/

MARINE. High pressure remaining centered off to the north and northeast will lad to winds becoming onshore later today and likely remaining either out of the southeast or south through much of the forecast. Winds should remain below 13 kts for much of the forecast with seas generally in the 2-3ft range. Will show seas to 4 feet at times due to persistent southerly or southeasterly winds possibly leading to a weak swell. /CAB/

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
