Summer ushered out with heat, but fall enters with cooling in Sacramento region

Summer goes out with a blast of heat and then a much cooler final day before fall arrives with the coolest day of the week in Sacramento.

The high on Sunday was 98 degrees in Sacramento, which is a dozen degrees above average for this time of year. Monday’s high also is expected to be pretty darn hot, with a high of 97 degrees forecast. Clear skies are predicted.

The last day of summer, Tuesday, will be fall-like, with high temperatures predicted to drop 10 degrees into the high 80s. Then, right on time, autumn arrives Wednesday with a dip to 84 degrees thanks to a low-pressure system dropping down from the Gulf of Alaska, according to the National Weather Service. It will be the coolest day of the week, forecasters say.

The detailed, seven-day forecast from the NWS for the Sacramento region:

Monday: Sunny and hot, with a high near 97. Calm wind becoming west-northwest around 5 mph in the afternoon.

Monday night: Clear, with a low around 64. West wind around 5 mph becoming light and variable.
