Higher humidity is expected for the remainder of the week as southerly winds will steadily filter in more humid Gulf air. For today, expect RH to bottom out in the lower 60s while winds will be southerly to southeasterly in the 10-15 mph range. A few gusts may push even higher, but should stay below 20 mph. Those gusts will be a good estimate for transport winds, which will also be largely out of the south. The influx of more humid air also means higher chances of late night and early morning fog. In general, this fog should be quite patchy and not particularly dense. However, there could be localized spots where the fog does get more dense - this will tend to be low-lying locations that have localized sources of moisture. Given the marshy location of the burn, and if there is remnant smoldering overnight, this may apply here. Because it will be so tightly tied to the localized moisture source, a dense fog threat should stay very close to the burn site, but may be a concern for any roads immediately against the burn unit. .REST OF TODAY...
