What forecasters said that day
The local office's own words before this small craft advisory went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS New Orleans, LA wrote its last area forecast discussion before this small craft advisory went out at Mar 22, 4:09 AM CDT, 12 hours 10 minutes earlier.
Area forecast discussion, Mar 22, 4:09 AM CDT, 12 hours 10 minutes before
Area Forecast Discussion National Weather Service New Orleans LA 409 AM CDT Mon Mar 22 2021 .SHORT TERM (Monday through Wednesday)... Biggest concern for the short term will be the potential for several rounds of heavy rain for the area. Overall current pattern has the current ridging over the southeast pushing eastward as low pressure intensifies as it moves into the Great Plains Tuesday then into the Upper Midwest/Great Lakes region on Wednesday. Strong moisture advection from the Gulf will start on Tuesday, and PWs quickly rise to the 1.75 inch range. Looking at SPC's climatology page, would be right near record highs for this time of the year. This rich moist air will hang around through around Thursday, setting the stage up for the aforementioned heavy rainfall threat. Rainfall efficient thunderstorms along with them training is also a concern Tuesday and Wednesday. Rainfall totals are looking at the 5 to 8 inches with locally heavier amounts possible over through Thursday. A non zero severe weather threat does exist for a limited time on Tuesday. Instability would be at its greatest when storms are forecast to fire fire up with models having up to 1200 J/kg for southeast Louisiana and coastal MS. Effective shear in the 30 to 40 kt range would be able to support severe storms, but winds are predominantly unidirectional so tornadoes are not as big as of a concern. Main convective mode would be linear. Biggest concern would be straight line wind gusts and maybe hail, on top of the heavy rain threat. -BL .LONG TERM (Thursday through Sunday)... The secondary shortwave trough is expected to move northeast from Texas across the middle to lower Mississippi Valley Thursday and Thursday night. The associated surface low, now trending quite a bit weaker on consecutive model runs, is fairly elongated from the western Gulf coast to the Arklatex to middle Mississippi Valley region through the day with the models having differing locations. Much of the jet stream level energy that will impact this system is still over a poorly sampled area of the north Pacific, so there will likely be some additional model shifts with regards to timing, position and strength of the major features and the placement of the heavier rainfall. The one thing that remains consistent is the analog guidance continues to show a strong signal for very heavy rainfall across the central Gulf coast, but confidence right now is highest with the heavy rainfall in our area Tuesday through Wednesday night, but less so Thursday and Thursday night. The same thing can be said with regards to severe weather potential on Thursday for the same reasons, but at least a low end (5-15%) probability of severe thunderstorms within 25 miles of a point seems about right at this time. Storm total rainfall of 5-8 inches is still expected on Mississippi coast and near Lake Pontchartrain from Monday night through Thursday night. A weak cold front will finally push through the region Thursday night, however this will only bring some drier air and not much cooler temperatures. Drier (not as wet) weather, but still some low rain chances from time to time, will persist Friday through the weekend, and hopefully additional rainfall will remain light since the area will be more than water-logged by that point with river flooding likely ongoing or worsening on some rivers at that point. A more substantial push of drier air with some cooler temperatures may finally arrive Sunday night. 22/TD && .AVIATION... VFR conditions will remain for the rest of this morning. Clouds will begin to build up and ceilings will to lower down to MVFR late this afternoon. The light and northeast to easterly winds will begin to move to southeasterly and will increase into the 10 to 15 knot range. -BL && .MARINE... Winds will be turning to onshore flow starting late tonight and will remain onshore for the majority of the week. Small craft exercise caution headlines may be necessary starting tonight as winds begin to pick up to the 15 to 20 kt range. Winds will remain elevated through Thursday. A weak cold front will then turn winds to an offshore flow for Friday before returning back to onshore for the weekend. -BL && .PRELIMINARY POINT TEMPS/POPS...
