More heat this week

Temperatures in the 80s will return starting today, Aug. 17, with a high near 84 degrees for Burlington, the National Weather Service forecast Monday. Thursday may be hotter, to 87 degrees. The lows both evenings are estimated to be near 60 degrees.

The weekend will not be as hot, with a high of 78 degrees forecast for Friday, a high of 79 degrees Saturday and 80 degrees Sunday. Lows will be in the 56 degrees range.

The cause is upper-level ridging building into the Great Basin Tuesday, allowing temperatures to rise into the mid-to-upper hundreds over interior California, prompting heat advisories and excessive heat warnings to be issued for the Sacramento and San Joaquin Valleys, as well as the parts of the interior Pacific Northwest, based on the National Weather Service analysis.
