The potential for light showers today may lead to minor disruptions, particularly for commuters. However, the more significant concern lies in the inland heat wave expected later this week. With temperatures nearing 100°F (38°C) by Thursday, residents in these areas should prepare for heat-related risks, including dehydration and heat exhaustion. Vulnerable populations, such as the elderly and those with pre-existing health conditions, may be particularly affected by the rising temperatures.
