A blast of summer is headed to Kerr County this week, with a forecast high of 106 on Wednesday

South Central Texas faces a potentially record-breaking heat wave this week as temperatures soar from spring-like conditions to dangerous triple-digit heat.

The National Weather Service warns that Wednesday and Thursday could bring temperatures that shatter all-time May records across the region, with Kerrville expected to reach 106 degrees Wednesday.

“This isn’t your normal mid-May heat wave,” forecasters emphasized in their latest bulletin. “It’ll likely be a historic heatwave given all available data for the upcoming week.”

Monday’s 93-degree high marks the beginning of a dramatic temperature climb. By Tuesday, the mercury will vault into triple digits at 102 degrees, accompanied by southwest winds gusting to 20 mph.

The heat peaks Wednesday with the forecast 106-degree reading threatening Kerrville’s May temperature records. Thursday remains scorching at 102 degrees before a slight moderation to 99 degrees Friday.

Overnight temperatures offer little relief, with lows remaining in the upper 60s to low 70s throughout the week.

Computer models show 850-millibar temperatures — measured roughly one mile above ground — reaching levels never before observed in the region’s historical record. Multiple forecast models indicate temperatures running 15 to 25 degrees above normal at that atmospheric level.

The European Centre for Medium-Range Weather Forecasts’ Extreme Forecast Index places this event near the top of all modeled climate scenarios for mid-May.
