4/9 – Trey Tonnessen’s “Severe Explanation” Tuesday Night Forecast

Meteorologist Trey Tonnessen

Wednesday’s first main area of concern, showing very strong divergence in the upper levels; will move through first while another area gets started over the west central gulf and also races northeast. This feature will mainly be a marine issue but some of these storms could move into Southeast Louisiana and coastal Mississippi by late afternoon/evening. The what, when and where have come together, or at least the best thinking has. The final answer will come when this area starts to develop late tonight and we can extrapolate with the main flow toward the area where this will line up. Precipitable water values are above 2.0 inches and even though they will be progressive, the rainfall rates with these storms could be quite high around 4 to 6 inches per hour which could cause some locations to get a few inches within an hour; causing some flooding issues as well. Winds will be strong enough to bring up a coastal flood advisory as well and with these winds over land 20-25 mph or higher with frequent gusts.

As always: A cloudy day is no match for a sunny disposition. Be nice to each other.
