As you can see, a couple of stations in the Catalina Mountains were virtually missed by the storm (ZERO total, for example, at Ms. Mt. Lemmon) or it snowed on those low total precip gauges and the snow has not melted and is sitting in the gauge’s funnel. Select choice number 2. Mountains just becoming visible; looks like snow down to 6,000 foot level.
Didn’t see any precip/virga before dark yesterday, started raining just before 10 PM, nicely, and continued through midnight when it quit. However, the main event, lasting about 6-8 h is supposed to start happening about now, but rain mostly lighting up in TUS. That means we should see some clearing around mid-day, but leaving enough low clouds stacking up around the Catalinas for some nice quilted sun and shadows on those mountains, one of our prettiest sights I think, along with our now snow-capped mountains.
FROPA, or “frontal passage” in weather text speak, occurred late yesterday afternoon. I wonder if you noticed the wind shift and dropping temperatures? However, was a very shallow depth of wind that shifted, and temperature took about 3 h to drop 10 F, (58 F to 48 F) not exactly as sharp a FROPA as was anticipated from this microphone yesterday. Also, a bit unusual, the rain band was displaced far behind the wind shift that occurred around 4:30 PM.
I thought yesterday was quite an interesting day for you. Lots of cloud types to log in your weather and cloud diary. Let us begin our retrospective with Sunrise on the Equestrian:
Your next storm: due in Sunday morning. Likely just something around a tenth of an inch. Nothing showing up beyond that, but lots of mod fluctuations re storms. I suspect the one that showed up a few days ago for the 20th or so will arise again in some future run. Just a gut feeling since there’s no evidence in the spaghetti plots yet to support that hunch.
1The TUS balloon sounding yesterday afternoon about the time of the next to last photo. Shows tops WERE warmer than -10 C, in case you didn’t believe me because the clouds looked so dark yesterday afternoon. They were pretty dark because there was a higher ice cloud overcast (Altostratus) and when droplet concentrations are high, clouds are darker on the bottom. We usually have pretty high droplet concentrations here in old Arizony.
