Rest of the work week: Hot, humid, scattered storms

/ August 5, 2020 at 8:11 AM

After Isaias, we find ourselves back in a wetter-than-normal summertime regime, with scattered thunderstorms possible each day as we remain under a trough of low pressure aloft. Plenty of atmospheric moisture will remain in place, allowing for heavy rain in any thunderstorms that develop. Be on the lookout for plentiful lightning, too, with the occasional storm turning severe with strong downburst winds.

Temperatures will remain generally around where they should be in early August: Upper 80s to low 90s. Mix in the humidity and heat indices in the 100s will be routine, with dangerous heat indices around 105° possible for Thursday and Friday.
