SACRAMENTO, Calif. — Friday is another Weather Impact Alert day for the Sacrament region because of the heat.
A Heat Advisory is posted for the Sacramento and San Joaquin Valleys along with the Foothills, Motherlode and Delta through Saturday night. Highs will be from 100-106°, nearing records for many areas. Overnight lows will also stay warm in the 60s to mid 70s. Heat related illnesses will be possible, especially for groups that are sensitive to heat.
An Excessive Heat Warning is in effect for the coast through Saturday evening due to dangerously hot conditions with temperatures up to 113° and overnight lows ranging from the lower 70s to lower 80s. Extreme heat will significantly increase the potential for heat related illnesses, particularly for those working or participating in outdoor activities.
The Records
Northern California just experienced its hottest summer on record, but the hits keep coming.
There's been 47 days with temperatures 100 degrees or hotter in Sacramento so far and there could be a few more that would extend that record. It's likely Sacramento hits 100 Thursday and would extend the record. If this happens, then it would be double the amount of 100 degree days we typically see in any given year.
- Stockton hit 105 Wednesday, breaking its daily record by four degrees.
- Modesto hit 104 Wednesday, breaking its daily record by five degrees.
Thursday temperatures will get close to records again for the region.
The coastal range and Bay Area will see widespread 100-degree temperatures in the valley and 100+ temperatures. There will be some relief for far Northern California and the immediate coast but that's about it.
Since it's so hot for October, it's worth looking at records. Here are some numbers of note:
