Drought conditions developing across Louisiana, Mississippi
NEW ORLEANS (WGNO) – The lack of rain across the Louisiana and Mississippi Gulf Coast is adding up, and drought conditions are beginning to develop across the areas.
In the last month, New Orleans has officially picked up 0.05″ of rain, almost 3 inches below the average for the time period. Gulfport, meanwhile, has only seen 0.15″ in the last month.
What this means for us is that drought conditions will continue to persist and worsen until meaningful moisture returns to the area. In the last week, the entire viewing area was declared in a weak drought by the National Drought Mitigation Center.
While October is one of the driest times of the year for our area, the recent lack of rainfall is unusual, and there’s no relief in sight.
The next front to slide through the area late on Wednesday will have limited moisture, if any, to bring to the area. Beyond that we remain bone dry into early November.
The reason is that high pressure continues to dominate our weather pattern and will continue to do so.
High pressure is associated with sinking air, and rising air is what is associated with rain.
The cold fronts we have had and the one expected to arrive tomorrow haven’t had the moisture available for any meaningful rainfall to affect the area.
In fact, Wednesday’s front brings only a 30% chance of a stray shower to the area. Almost all of the forecast models keep us dry after this front and staying dry through the first week in November as high pressure looks to develop once again across the Southeastern united States behind the front.
