WeatherQuestion 63 of 100
A METAR reads: KMEM 231553Z 09006KT 2SM BR OVC004 08/08 A3010. What do the elements 2SM BR tell you?
a.Visibility of 2 statute miles restricted by mist
b.Visibility of 2 statute miles restricted by blowing rain
c.A 2,000 ft ceiling with a broken layer above it
d.Visibility of 2 nautical miles restricted by drizzle
Explanation
Surface visibility in a US METAR is always given in statute miles, and BR is the code for mist, so 2SM BR means 2 SM visibility in mist. The temperature and dew point of 08/08 show a zero-degree spread, which is exactly why the air is saturated and mist plus a 400 ft overcast are present. BR is not blowing rain, visibility is never reported in nautical miles, and cloud amounts are reported separately in the OVC004 group.
