The extent of the cloud cover and Kay's proximity to the coast will determine how much cooling occurs. "Most of the cooling effect in Southern California, southern Nevada and Arizona late this week and this weekend will be due to increasing cloud cover associated in part from Kay at sea and a plume of tropical moisture that is likely to spread northward on the storm's right side," AccuWeather Senior Meteorologist Brett Anderson said. The other factor will be how close Tropical Storm Kay and its moisture will get to the northern part of Baja California, Mexico, before being turned westward and out to sea over the Pacific. One factor in determining the extent of the downward trend in temperature will be how much the high-pressure area weakens. This will allow a front with cooler air to slice southward from Canada, through the Northwestern states and into the central Rockies. Prior to this month, the September high-temperature mark of 100 degrees was set on multiple dates ranging from 1979 to 2020.Ī vast area of high pressure that has been parked over the interior West is likely to weaken slightly during the latter part of the week and this weekend. Salt Lake City had initially set an all-time September high on Thursday, when the temperature hit 102. AccuWeather meteorologists say there is the potential that this newly established record is topped through Wednesday. Salt Lake City recorded a new all-time high temperature for September when the mercury hit 103 F on Saturday. RELATED Northern California wildfire kills 2 women
