On pace for the most July hours of temps below 70F since 2009. The dews have only been above average because we've been saturated for 90% of the month.
ASOS doesn't really distinguish between the two...it's just a vis sensor. So the HZ vs BR obs are all based on the dewpoint depression. A vis of 4SM or less will result in BR (or FG if it's low enough) and anything over 4SM is HZ.
