3/20 – Brittany’s “First Day of Spring” Sunday Evening Forecast

As we finish this evening, not bad at all to close out the weekend! It will be quiet going into tonight with upper-level clouds increasing.

On Tuesday, a regional severe-weather outbreak — including potential for several tornadoes (a few potentially significant) remains evident.  Severe storms — including tornado risk will likely be ongoing at the start of the period, as a surface cold front moves steadily eastward. Tornadoes (along with damaging winds and hail) will be likely with storms shifting eastward in tandem with the cold front.  Our area will be under an “Enhanced” risk, which is a level 3 out of 5.

Additional hazards: We will likely reach wind advisory criteria during the day on Tuesday, especially for the south shore of coastal SE LA and coastal areas east across MS. Strong onshore flow may also result in higher than normal tides as well on Tuesday. Furthermore, ample moisture content and high PW`s will support heavy rain possibly leading to flash flooding concerns, especially for areas along/north of I-10/12. The potential for a Flash Flood Watch will also be assessed in subsequent shifts.
