Not now, but during past hour

Pas de résumé, désolée.

Following the link to the World Meteorological Organization chart of weather symbols in Roger Shuy’s LL post, I wonder if Eskimos there are people who have a word for any of the following concepts: “freezing drizzle or rain (not showers), not now but during (the) past hour” or “fog, sky not discernible, and has become thinner during (the) past hour” [including the delightfully vague subject reference], or indeed “snow showers, not now, but during past hour”.

Because even if we have no word for it, the WMO sure has a symbol for it.
