Thunderstorm Dynamics and Moisture

• 💧 A key factor for this week is the influx of subtropical moisture being pushed in from the south, influenced by Tropical Storm Mario affecting Mexico.

• 🌡️ While overnight temperatures will cool, the combination of warm, moist air and afternoon heat creates updrafts and downdrafts conducive to thunderstorm development.
