Today’s official high temperature was 97 and the high heat index was 106.

The global GFS overshot the temperature forecast. The mesoscale models (NAM, WRF, HIREF) did better with the temperatures but over-forecast the pop-up showers in a big way.

Tonight’s models, just becoming available, are predicting a hotter day on Sunday than Saturday. Highs are coming in at 98-100. Thunderstorms move in from the northwest after 8PM Sunday evening.
