Thursday's temperature forecast for Hermiston, Oregon (Motto: "Where Life is Sweet") seems a little strange, with a wintry mix expected. The MOS high temperatures are in the 30's, but the National Weather Service forecast was originally 27 F, then bumped up to 31 F. One of the MOS forecasts has the maximum only 2 degrees higher than the minimum, which is not very common. And the NWS hourly graph shows temperatures below freezing during the afternoon but with rain instead of snow (probably freezing rain). Let's see if we can untangle things and predict the Tmax for Hermiston.
Question: What does "diurnal" mean? For Hermiston, what is the average diurnal temperature range for this date?
