For all the data geeks out there. Here’s the MESOWEST screenshot for my station from the zone of totality here in Dallas, showing changes before, during and after. Totality occurred at 13:40 and lasted through 13:44. Since the column headers were chopped, they are left to right:
Time, Temp, Dew Point, Wet Bulb Temp, Relative Humidity, Wind Speed, Wind Gust, Wind Direction, Quality Check, Pressure, Sea Level Pressure, Altimeter, 1500m Pressure, Solar Radiation, Precipitation 24hr, Precipitation since local midnight.
