If you like to plan outdoor work ahead of time, here is a site that might be useful to you this summer. The Weather Prediction Center has a bunch of very useful prediction maps, including predictions for heat index, which is related to high temperatures linked with high humidity. The map for this coming Friday shows that southern Georgia and down into Florida are expected to see heat indices of over 100 F, which means extra precautions are needed for outdoor workers. The area even expands on Saturday. You can check these medium-range forecasts to see what days are likely to be the hottest for work planning. This page of small multiple maps give a look ahead for days 3 through 7 for a variety of different temperature thresholds. You can click on individual maps to enlarge them. The left menu leads to a lot of other useful information, including the QPF maps I post each Saturday.
