Prompt: Craft a weekend-focused weather guide that begins with fog and heat on Saturday/Sunday, then explains how a decaying front and a cross-country storm system will bring changes midweek. Translate the forecast into a practical plan for readers: fog-driving safety, heat hydration tips, and indoor-outdoor contingency for scattered storms. Include a brief note on timing and where to expect the strongest activity, plus a simple lightning safety rule. Add a small, reader-friendly visuals idea (hourly forecast bar) to help plan events. End with a concise takeaway about the seasonal transition from warm weekends to a cooler front.
