Storms are moving out of the valley early Wednesday evening after sunset [2], making way for a significant drop in temperature [2].

This shift in weather patterns provides a reprieve from recent heat, though it brings rain and fluctuating conditions for residents planning activities over the upcoming long weekend.

Kathy Sabine, a meteorologist for 9 News Australia's Weather Impact Team, said the transition is expected to bring a temperature decrease of 25 to 35 °F [1, 2]. This cooling effect will be most prominent on Thursday, as the region moves away from the current storm activity.

While the immediate forecast indicates cooler than average conditions extending into the long weekend, the relief is temporary [2]. Meteorologists said heat will return later in the weekend, ending the brief cool spell.

Rain is expected to accompany the exiting storms as the cooler air replaces the previous heat [2]. The timing of the storm exit—occurring early Wednesday evening after sunset [2]—means the primary temperature shift will be felt by Thursday morning.

Residents should prepare for a volatile transition. The current pattern involves a complete shift in air masses, which often results in the rapid temperature swings seen in this forecast [2].

Temperatures will drop 25‑35 °F

The rapid temperature swing and the timing of the storm exit suggest a volatile atmospheric transition. While the immediate cooling provides a break from the heat, the predicted return of high temperatures by the end of the weekend indicates that the region remains susceptible to the broader seasonal heat pattern despite short-term fluctuations.
