Several quick shots at rain over the next several days
A series of weak storm systems will race through the region into next weak bringing scattered showers to the area as they do.
Today and Tonight: By Thursday, skies will show thickening clouds with rain arriving through the afternoon from southwest to northeast. Highs will stop in the low 60s on account of reduced sunshine. Showers will continue overnight with lows in the low 50s.
Up Next: Most of the rain will wrap up by dawn Friday. Though there could be a few straggling showers early, general clearing is expected from skies into the afternoon. Highs will move into the upper 60s. Friday Night will be clear and cool with lows in the mid 40s. The weekend will begin with partly sunny skies and a high in the low 60s. Another fast moving storm system could bring some showers across the region Saturday Evening followed by cooler air and dry conditions for the second half of the weekend.
Meteorologist Josh Eachus goes into greater depth about your weekend weather, timing out several rain chances in this VIDEO.
Forecast Discussion: A shortwave trough sliding over the baroclinic Texas Gulf Coast will help to develop a surface low pressure system. This weak storm will ride northeastward towards the Louisiana Coast. Rain is expected to break out by Thursday Afternoon, advancing northward into the overnight hours. A few trends that forecast models have picked up on—the first would be that most of the steadier rain will stay in extreme Southeastern Louisiana; the second being that the timing has narrowed considerably to a 12-15 hour window Thursday Evening into Friday Morning. Most of the action may be shut down by the Friday Morning commute and sun is expected to return in the afternoon. Yet another shortwave will roll through the region on Saturday with little moisture to churn out a widespread rain event. We’ll mention scattered showers—primarily after dusk Saturday. This system certainly has some implications for the Louisiana Marathon. If current timing holds—the morning events on Saturday will be dry and the spotty showers will conclude by dawn Sunday, just in time for the marathon and half marathon. A cold front will sweep through the region Saturday Night and cold air advection will kick in Sunday. Therefore, highs and lows will run about 5-8° below average for the second half of the weekend into next week with a mix of sun and clouds. The third wave is timing out for Monday Night—again with limited moisture.
