San Diego County experienced an influx of monsoonal weather patterns early this week, bringing showers and isolated thunderstorms to the region, giving residents temporary relief from summer heat, but adding to humidity concerns, Fox 5 San Diego reported. An inverted atmospheric trough moved through the region from Imperial County, supporting increased chances of showers and thunderstorms over the last couple of days.
The atmospheric conditions likely to trigger this activity were at their strongest on Monday, July 31, according to the National Weather Service (NWS). Although widespread heavy rainfall or flooding did not occur, the agency cautions San Diego County residents to be aware of brief heavy downpours and lightning. By Tuesday afternoon, the NWS reported that atmospheric support for thunderstorms had weakened.
In a distinct article, 10 News stated that the monsoonal flow would continue through Tuesday, bringing the chance for showers and thunderstorms across the county, including coastal and beach communities. The majority of the activity was confined to the mountains and deserts, but much of the moisture moved westward throughout the day. The article also advised caution when traveling through the foothill, mountain, and desert highways due to possible gusty winds and rapid rainfall amounts caused by thunderstorm activity.
As warm air aloft continued to hold onto moisture, residents experienced muggy and uncomfortable conditions, 10 News mentioned in the same article. However, the weather began to change by Wednesday, August 1, with another 10 News report stating that August started on a quieter note with less shower and thunderstorm activity. Isolated thunderstorms persisted in the eastern half of the county, but overall, the weather was drier. The report also cited that monsoonal moisture would flush out by August 2, allowing cooler and drier air to filter in, providing more comfortable conditions for residents through the end of the week.
Coastal areas were expected to experience some fog with clearing by mid-morning, leading to a pleasant day, according to 10 News. However, San Diego residents were warned not to get too comfortable as another warming trend was forecasted to set in on Friday, August 4, Fox 5 San Diego noted. The warm-up is expected to be more gradual and less extreme than previous heat events this summer, with highs exceeding 110 degrees in the lower deserts by the weekend and most other areas in the region topping out around five to ten degrees warmer than usual.
While monsoonal weather may have provided brief respite from the sweltering heat in San Diego County, it's essential for residents to remain prepared for fluctuating temperatures and potential thunderstorm activity as we progress into August. Although somewhat subdued, "monsoon madness" still lingers in the air, keeping San Diegans on their toes and ready for whatever Mother Nature has in store.
