Last weekend had an extensive list of record highs that were either tied or broken across the Southwest eastward into Texas and this weekend is no exception. Several records were set on Friday from Texas to California, Oregon to Washington.
Fortunately the heat bubble will shrink on Saturday in the Southwest with a slight shift in the weather pattern. However, an Excessive Heat Warning will remain in effect for the Death Valley, CA area.
The heat is being driven by a big ridge of high pressure anchored across the Southwest, leading to a widespread sinking air. Remember, when air rapidly sinks, it compresses. That leads to air molecules moving faster. The friction from those invisible rapidly-moving air particles is what you feel as heat!
Highs will continue to be above the century point in the deserts, with 90s found elsewhere. Several records will likely fall into this weekend, even into the Northwest.
