San Diego residents can expect a slight temperature increase today and Monday, with highs reaching 5-10 degrees above normal in the deserts. Coastal areas will continue to see low clouds and patchy fog in the marine layer during the nights and mornings, a common pattern for the locals, as reported by the National Weather Service in San Diego.
Further details provided by the National Weather Service indicated that while inland temperatures are rising, the onset of cooler weather midweek should bring temperatures back down to seasonal averages, although there is a growing possibility of monsoonal thunderstorms later in the week. Notably, the ridge of high pressure that's been affecting the region is posited 135 miles west southwest of San Diego, sustaining the warmer inland conditions through Monday however, as we step into Tuesday and onwards, the high pressure is expected to weaken and shift eastward due to a low pressure system moving over the Pacific Northwest.
In the meantime, for those planning to spend time at the coast or venturing into the western valleys, the weather service's Area Forecast Discussion recommends preparedness for low clouds with bases around 1100-1500 feet MSL in the mornings, with localized visibility reductions possibly reaching 3-5 miles. Aviation interests should note that VFR conditions are anticipated to prevail in the mountains and deserts through Monday.
Mariners will be pleased to know that no hazardous marine conditions are expected through Thursday, keeping the waters favorable for boating and other maritime activities.
