BALTIMORE — Good Wednesday evening!
The heat and humidity have led to unhealthy air quality in sections of Maryland today. This is due to high concentrations of pollution getting trapped in the lowest levels of the atmosphere. The heat reduces the natural ventilation we see in the atmosphere - trapping unhealthy air near the surface! Those who suffer with respiratory issues should stay inside.
We have one more hot day (Wednesday) before a front slides through Thursday - delivering our next round of heavy rain! The flood threat is moderate Thursday as moisture levels remain high in the upper atmosphere!
Here's the good news - cooler and less humid air arrives Friday! Cloud cover will keep high temps in the 70s! Humidity levels drop drastically, too! To put it in perspective - the dew point today reached the low 70s, but it will fall to the 50s by the weekend! Saturday and Sunday will be an early preview of September, with lower temps and less humidity!
