From Elliot Wilson:
Sunshine dominates all day long on Sunday, warming us up quickly. The Heat Index will be in the triple-digits by midday, before the thermometers hit the triple-digits in the afternoon. The Heat Advisory may be extended into the beginning of the work week as it’ll still be hot and humid to the point where Heat Index values could still be around 105° Monday afternoon.
However, a little bit of relief is set to arrive during the middle and end of the work week. Dew points will drop during the middle of the week as a low pressure in the four-corners region will pull in drier air from the southwest, bringing dew points down into the low 60’s Tuesday through Thursday. Also, that same low will bring us some spotty rain chances on Thursday and Friday. However, as we head into next weekend the rain chances disappear and the humidity will be on the rise again.
