wxdude64 Posted May 7, 2020 Share Posted May 7, 2020 So, I set new records (see above). But now that I've had a nap (working 11-7 shift) and looking around at local CO-Ops, seeing the newer, less than 50 year old locations set records too, but the older stations did not. 1917, 1906 and 1968 were VERY cold! The records there are 3-8 degrees colder than what I and newer stations set yesterday/today. Link to comment Share on other sites More sharing options...

jonjon Posted May 7, 2020 Share Posted May 7, 2020 We need to squeeze 2 more inches out to get to triple digits for the season. Haven't had one below 100" since 01-02.

CAPE Posted May 8, 2020 Share Posted May 8, 2020 Model snowfall maps are always wrong. Still looks like a coating to a couple inches for the western highlands. I mean, it is May. Link to comment Share on other sites More sharing options...
CAPE Posted May 8, 2020 Share Posted May 8, 2020 Looks like there are still some pretty significant differences among the guidance on rainfall amounts/specific location for the region. Generally looks like the heaviest will be in the northern third, but some Mesos have another max on the coastal plain. Link to comment Share on other sites More sharing options...
