Arizona Weather Force has issued the Enhanced Severe Thunderstorm Watch effective for August 21, 2024, lasting into the overnight for some …

Zones Issued For: Maricopa County – Pinal County – Gila County – Graham and Greenlee County – Cochise County – Santa Cruz County – Pima County – Flagstaff – Prescott and Chino Valley –

Discussion: A ridge of high pressure is teaming up with an upper-level system out of Mexico. The first system is already showing itself with the windy conditions across Casa Grande to the San Tan Valley areas. This system will clear as the afternoon moves on. Clearing skies across Northwest Mexico and Cochise County right now will continue to elevate the instability conditions. This will pop-up the main event of storms there today, and eventually it will move northwest along I-10 through Pinal County and into Maricopa County as well, and then move further north into the Prescott/Payson forecast zones overnight, and Flagstaff as well.

There is a good chance that Prescott will have an all-night lightning show with this one as outflow boundaries and upper dynamics bounce back and forth.

Severe Thunderstorms can and do produce tornadoes …

An Enhanced Severe Thunderstorm Watch is issued 0-12 hours before an event is expected to happen and must be taken seriously if you are in that watch. Storms will produce the risk of tornado dynamics, damaging winds, large hail, and flooding in the most powerful cells.

As always, we take it one day at a time with these events.

He has certs from Mississippi State for broadcast met and Penn State forecasting certs MET 101, 241, 341 and 361 as a meteorologist, but before then was completely self-taught, barely learning a thing from the schools that he did not already know.
