The episode as NWS MFR wrote it up.
A Frost Warning was issued for the Rogue and Umpqua Basins. Most of the reported low temperatures were in the middle 20s to upper 30s, so frost probably did occur this morning.Three stations in the Rogue Valley and three stations in the Umpqua Basin met Freeze Warning criteria, and a Warning probably should have been issued for those zones. Additionally, one station each in a coastal zone and in south central Oregon also met freeze warning criteria, but the very low temperatures did not appear to be widespread in these zones. A frost warning would have probably been sufficient for the coastal zones, but none was issued.
