The current Bay Area heat wave might have an unusual interruption this evening, when forecasters say thunderstorms might strike San Francisco and the South Bay.
Will Pi, a meteorologist with the National Weather Service tells the Chron that after days of sweltering temperatures, a"cooldown is expected to sweep into the Bay Area starting on Thursday."
And with that cooldown comes possible stormy weather, NBC Bay Area reports, as "an area of monsoonal moisture will move into the southern portion of the Bay Area."
With that area could come "thunderstorms and dry lightning strikes" as well as "above-average humidity."
As we discussed a couple years ago, thunderstorms are rare in the area as the geography of our part of the West Coast tends to get much of our weather via cold fronts coming in off the Pacific, while thunderstorms tend to ride along warm fronts and require heat and humidity. So the current warm wetness might be the perfect recipe for a couple Bay Area booms.
The storms, should they arrive, as expected late Thursday evening. Until then, NBC says SF can expect a high temperature of around 75 today. Those temps will, the Chron reports, "stay relatively the same through Friday before cooling down for the weekend."
