In addition to the forecast hot temperatures for inland areas — with some parts expected to hit triple digits — the region will be on the lookout for possible dry thunderstorms and possible lightning in addition to gusty winds up to 30 mph that could fuel the quick spread of any wildfires sparked during this period.
Forecast models are showing a better chance of showers developing late Thursday into early Friday as an upper-level storm system funnels sub-tropical moisture and instability toward the Bay Area, according to KPIX 5 meteorologist Paul Heggen.READ MORE: Afghan American Family Finally Returns to California; 'It's A Story Of Hope'

While short-range, high-resolution models aren’t showing any lightning yet, the European forecast model has been indicating a “non-zero threat of lightning,” Heggen said. While there appears to be a low probability of lightning, it remains a high-consequence scenario due to the dry vegetation conditions brought on by extreme drought.
The announcement comes after the California ISO declared a Flex Alert for Wednesday afternoon that goes into effect at 4 p.m. due to the expected hot temperatures.MORE NEWS: Will The Oakland A's Strikeout With Fans Over Proposed 2021 Ticket Price Hikes?
