Monsoonal Moisture Continues for Acadiana

Deep tropical moisture from the Gulf of Mexico combined with a weak low pressure trough aloft will persist across Louisiana acting as a mini-monsoon with good chances of rain and embedded storms through much of this week.

As a result daytime chances of showers and storms will be in the range of 40-70% while the risk of showers may also continue at night but will be closer to the 20-40% range.

This pattern fortunately will keep our daytime highs closer to the mid-upper 80s over the next several days.  A little more sunshine will be possible later this week, but that will serve to de-stabilize the atmosphere engendering a good scattering of afternoon showers and storms.

Generally, in this type of pattern the threat of severe weather is minimal, but the risk of torrential downpours, frequent lightning and perhaps some tropical funnel clouds will be possible, especially if some pre-activity sunshine is mixed in.

Daily rain totals will likely stay in the one third to one half inch range, but isolated amounts on any given day of up to 2 inches will be possible where heavier storms manifest at least through Thursday.

Interestingly enough, the long-range pattern continues to indicate persistence of a similar pattern with at above normal daily rain chances through the weekend and for perhaps a good part of next.

The Atlantic Tropics remain quiet.
