The National Weather Service has issued a Heat Advisory beginning at 9AM lasting until 7PM this evening that includes JSC.
At 8:10 AM this morning JSC Bldg 30 was 83 degrees with a heat index of 94. This temperature was 2 degrees warmer than yesterday and humidity is slightly higher than yesterday at that time. The forecast high at JSC Bldg 30 today is 93 which is only 1 degree below the JSC record for today. The combination of near record heat and humidity will send the heat index above 100 shortly before noon and above 103 by 1 PM. NASA Ellington Field, Sonny Carter Training Facility and portions of JSC further away from Clear Lake will likely see slightly higher temperatures and heat index readings.
The NWS issues a Heat Advisory when the heat index >= 108 or the temperature >= 103 F. Please take extra precautions if you work or spend time outside.
