Tonight and Tomorrow: Tonight, we’ll begin to see a little bit of clearing but overall mostly cloudy conditions will remain across much of south Louisiana. Lows will be in the upper 50s to low 60s. It will be a cool start Sunday morning, but we will warm to around 80 tomorrow afternoon as sunshine returns to the forecast.
Looking Ahead: The weekend will end out dry with plenty of sunshine on Sunday. As we head into next week, we’ll be tracking two big features: a cold front and a tropical system. Both could have impacts on our local forecast by mid-week. Tuesday, there may be enough available moisture and instability to get a few showers to pop up in the afternoon. The main weather system will come into play on Wednesday, with a cold front and associated upper level low, that could deliver a round of storms across the region. To make things more complex, Tropical Depression 28 in the Caribbean is also expected to draw in more moisture into parts of the northern Gulf Coast.
Tropical Depression 28:
The first forecast cone for Tropical Depression 28 has future Zeta briefly reaching hurricane status on Tuesday, then weakening into a tropical storm on Wednesday before reaching the northern Gulf Coast. The environmental conditions in the southern Gulf are more conducive for strengthening, but more harsh conditions will begin to take a toll on the storm as it closes in on the Gulf Coast.
As we have seen with past storms this season, the track can and will change with time. Right now, it’s time to pay attention and plan on the possibility of tropical storm conditions somewhere in south Louisiana mid – late week.
