We finally broke the streak of days with temperatures of 90 degrees or hotter on Sunday. That was a 16-day streak, a record in May over the last 20 years, and this month could be the hottest May in recent memory — right now, we're averaging about 92 degrees per day. The forecast looks cooler until Thursday, when temperatures start to kick up. Later today, we can expect thunderstorms, which could stick with us until Wednesday. The storms will keep us cooler, with Wednesday's high suspected to be 76 degrees. But the rain? We will believe it when we see it.
