The wxJabber model index is 78 and conditions are LIFR. The METAR is decoded: San Antonio reporting winds from 080 at 6 knots, visibility 0.125 miles, and vertical visibility at 100 feet in light rain and mist. The RVR for Runway 12R is variable between 2600 and 3000 feet. The temperature 66.2*F, dewpoint 64.4*F, relative humidity is 94 percent. The barometric pressure is 30.13.

Historical data reveals that conditions at San Antonio have been LIFR since at least 3:00 A.M., and the TAF indicates soggy conditions for the rest of the day:
