The National Weather Service in Sacramento has issued a Heat Advisory for a significant portion of the Sacramento valley, including all of Solano County.
In a forecast bulletin published on Tuesday, a meteorologist with the weather agency said high temperatures will range from the upper 90s to around 107 degrees throughout the region.
Northern parts of Solano County are expected to see the worst of the mini heat wave, with Vacaville, Dixon and rural parts of Winters impacted by hot weather until at least Thursday.
In Vacaville, the thermometer reached 106 degrees, according to an observation map published by the National Weather Service and reviewed by Solano NewsNet. Dixon fared slightly better with a high temperature of 104 degrees, while Travis Air Force Base logged 102 degrees.
The Fairfield and Rio Vista area saw slightly cooler weather, with temperatures in the low- to mid-90s in the afternoon. Benicia and Vallejo were the coolest parts of the county — temperatures only reached the mid-80s there.
Cooler weather is expected from Thursday onward, with as much as a 20-degree drop possible in some areas.
With the decreasing temperatures comes the chance of isolated thunderstorms with very little rain, which has raised concerns over possible dry lightning strikes that could spark new wildfires in some areas.
Forecasters say the highest chance of thunderstorms will occur in the overnight hours between Thursday evening and early Friday morning, with the storms likely occurring in the higher elevations.
