NEW ORLEANS (WGNO) — It’s going to be hot for a while. Look for lows in the upper 70s to low 80s tonight but it will take a while for the heat index to drop below 90.
We won’t see any changes for the next few days. A heat advisory is in effect across the area Wednesday with heat index values of 108 and above likely for most of the area at least for part of the day.
The main difference from last week is that the atmosphere higher up will be a little drier. So as we warm up each day some of that drier air may mix down to the surface. Instead of dewpoints around 78-80 we will see those numbers around 73-76. This is still humid, but just a bit less miserable than the past week or two.
That will also mean slightly lower morning lows. Expect mid to upper 70s in the morning as opposed to low 80s.
Daytime highs will still be hot though with most of the area at 95-98 through Friday and not much rain chance. Saturday will also top out in the mid 90s before rain chances move in. Right now that looks to happen late in the day and then again on Sunday.
