فُقْأَةٌ

Also (tropical:) A cloud in which is neither thunder nor lightning, and the rain of which is مُتَقَارِب [apparently meaning drawing near: as though likened to the membrane thus called]. (O, * TA. [In the former written, in this instance, فَقْأَةٌ, which I think to be a mistranscription by the copyist.])
