Mammoth to Bishop Weather Discussion: A strong spring ridge of high pressure is moving into the area, bringing some significant warming from Mammoth down to Bishop.
This could be the first time you see a 60 in Mammoth Lakes and 80 degrees in Bishop this year.
This ridge will kick up temperatures, turning the snow packer over to spring, possibly all the way to the Sierre Crest during the ridge peak early this week.
The warm-up will be short-lived as a long wave trough pattern will set up later in the week, lasting what looks like at least 7-10 days.
More extended-range ensemble models show 3-6 inches of water as of last night and on the 6z runs this morning.
