Tonight: Tonight will see some lingering clouds and foggy conditions with lows in the upper 60s. A dense fog advisory is in place from 11 pm until 9 am for areas generally around and north of the I-10/I-12 corridor.
Tomorrow: Cloudy to start the day before clearing to sunnier skies. Highs will be warm in the mid-to-upper 80s with muggy conditions. Winds will be from the east around 5 to 10 mph.
Beyond: High pressure will continue to amplify over the region by Monday which will support above average temperatures into the mid-to-upper 80s. No rain is expected through the week; however, dewpoints will be in the 60s to allow for muggy conditions.
Winds will shift to be northeasterly, which will begin to lower humidity and bring down temperatures Wednesday into Thursday. A cold front looks to move through Friday into Saturday to bring much cooler temperatures with highs dropping into the 60s. Moisture will be limited, so not expected much, if any, rain with the frontal passage.
Tracking the Tropics: Invest 98L, located north of Puerto Rico, has a good chance for tropical development over the next day or two. Model guidance continues to suggest that it will impact Florida and move towards the west over the state; however, an incoming upper-level trough from the west should pick it up and take it to the northeast.
This system looks like it could be a moderate tropical storm to low end category 1 hurricane. Coastal flooding and heavy rains could be a problem up the east coast into the Mid-Atlantic states due to the large size of the system. Regardless, we will keep a close eye on it. For now, there is no imminent threat to Louisiana.
