Area Forecast Discussion...UPDATED National Weather Service New Orleans LA 948 PM CDT Mon Mar 18 2024
NEW 06z AVIATION
UPDATE
Issued at 851 PM CDT Mon Mar 18 2024
With the loss of daytime heating, temperatures across the forecast area are starting to drop into the upper 40s and 50s respectively.
The 00z sounding shows quite a mixed boundary layer. Now that the temperatures are falling, a radiation inversion will develop as some rad cooling takes place with the lack of cloudiness.
Gradient winds are still elevated closer to the coast, however, we are starting to see winds decrease to 5kts or less across southwest MS...basically where the Freeze Warning is currently in effect. There is still questions in terms of surface winds a tier or two of counties/parishes south of the current freeze headlines.
Think along the immediate coast winds will remain just high enough to eliminate the potential max radiational cooling, however, if winds calm over night along the I12 corridor in LA or north of I10 along the MS Gulf Coast, some MinTs may flirt with freezing, especially along the Pearl River or Pascagoula/Escatawpa basins. For now the ongoing forecast seems to be on track so we will continue to keep the wind forecast untouched, but a short fused freeze headline may be needed along the I12 corridor in SE LA and north of I10 along the MS Gulf Coast. (Frye)
SHORT TERM
(This evening through Wednesday night)
Issued at 400 PM CDT Mon Mar 18 2024
Drier air and plenty of sunshine has allowed us to warm up today a bit more than was expected. Much of the area was in the upper 60s and low 70s today. PW is around 0.5-0.6 inches this afternoon thanks to the drier low-level air mentioned earlier. That is around the 25th percentile for today, showing how abnormally dry it is out there. The tightened pressure gradient behind the cold front that passed this morning has caused some gusty northerly winds this afternoon with the help of thermal mixing.
The center of the surface high trailing the front will move over the area late tonight and into Tuesday morning. This will help back winds down for Tuesday. Although surface winds seems to back down, cold-air advection still seems apparent Tuesday morning, so lows were bumped down from NBM across the area. This led to freezing temperatures across much of SW MS and the adjacent Florida parishes. Freezing temps will only last for maybe and hour or two because as soon as the sun comes up, we will warm up pretty rapidly. You can thank even drier air for that because the drier the air, the more of a diurnal temperature curve you get. Thanks to much drier 850mb air, PW will drop all the way down to 0.2 inches tomorrow, rivaling the daily min for that day of 0.25 inches.
Like was mentioned before, the aforementioned drier air on Tuesday will cause air to rapidly warm throughout the day. So, that coupled with the clear skies expected on Tuesday, cause the temps to get bumped up from NBM using a blend of NBM 75th and 90th percentile. The dry air and sunshine will also cause dewpoints to mix out efficiently at the surface, so NBM 10th percentile was used for that as well. This drops our RH to below 25 percent for most of the area, so be careful burning tomorrow if you do.
Thankfully, since the center of the surface high will be overhead, winds will not be an issue for fires.
By Wednesday, the surface high slides to the east and we get return flow setting up. This will moisten us back up where PW will get back above 0.5 inches, although still abnormally dry. This also allows temps to continue to get warmer and actually feel like Spring for the first day of spring!
LONG TERM
(Thursday through Sunday night)
Issued at 400 PM CDT Mon Mar 18 2024
Thursday, another upper level system is expected to influence the area as a low moves through the southeast US, which will enhance rain chances Thursday into Friday morning. Southerly surface winds ahead of the frontal system will help to advect warmer and moist air into the region, enhancing instability as well. There are still quite a few uncertainties in the model consensus in the mid- range forecast, mostly surrounding the amount of rainfall expected. Some are drier while others show more of a potential for training. Our forecast has been trending a little drier to be more in line with growing trends in the forecast. PoPs are still in the 30-50% range.
After the system moves through, ridging will dominate the upper level pattern and conditions will be dry Friday through the weekend.
Northerly surface winds Friday through Saturday night will help keep conditions a little less humid, but highs will still be pushing 80 degrees this weekend. Sunday will be mostly a transition day for the atmosphere as surface winds shift back to southerly and moisture is reintroduced to the atmosphere. MSW

VFR conditions will prevail. Otherwise, northerly winds will start out gusty closer to the coast/lake, but should decrease through early morning. Eventually the winds will become light and variable with little if any flight concerns through the cycle. (Frye)

Gusty northerly winds behind the cold front has caused hazardous seas today through tomorrow morning. Once the center of the surface highs gets overhead, the winds significantly back down below impact thresholds, and benign conditions stick through the end of the week. There is another shot of rain Thursday with the next system, but there is still some uncertainty on timing and location of the rain.
