Temperatures heat up, as tropics look more active

It'll be the heat that takes up most of the weather headlines here in south Louisiana through at least the weekend with a typical summer heat wave moving across Acadiana.

This is coming as a ridge of high pressure in the west starts to expand, and in so doing, pushing out a lot of the moisture we've been dealing with and replacing it with some drier air.

We've got the temperatures warming up along with that drier air and the highs will push up into the mid 90s by Saturday, the heat index will sit in the triple digits over the next several afternoons.

These kinds of temperatures aren't uncommon in south Louisiana but it doesn't mean we should take the temperatures any less seriously, in this kind of heat you'll want to take it a little slower.

So as a reminder, make sure that you're drinking plenty of water and avoiding strenuous activity during the hottest parts of the day.

It's also that time when you shouldn't leave anything in your car as it basically will turn into a mini oven, kids and pets certainly shouldn't be left, but even unopened cans can pop when the temperatures get this way.

This hot, quiet pattern will run through the rest of the week and into the weekend and it won't be until the end of next week that we'll start to see a break in this kind of pattern.

In the tropics we are starting to see a slight change in the pattern which may indicate that the season, which has already been record-breakingly active, may really be switching on.

This comes as we will likely see the "F" named storm (Fay) become the fastest we have reached that name since we've been keeping records, a likely tropical storm will develop off the Atlantic seaboard.

We've been lucky so far with a solid plume of dust and dry air choking off the central Atlantic Basin, but some of the early season waves look like they're going to start coming off the African coast.

These early waves don't necessarily all become tropical systems, but they do eat away at that dry air and mitigate a lot of that dust, which makes the environment more favorable for the following waves to develop.
