I trust Ryan with content going forward, but that relationship with Joerg is strange to me. I couldn’t understand why they partnered and then Joerg beefed up weather.us and paywalled some of that too. I sense more stability with WB.
Pretty much. When the droplets become too heavy for the updrafts to support them they fall to the ground. Of course in glaciated clouds you start dealing with the bergeron process instead of collision coalescence. So you have a supercooled condensation nuclei and differences in vapor pressure between the ice crystals and water droplets. The ice crystals readily gain H20 from the vapor and grow according to their respective habit at a given temperature and RH...ie snow crystal growth by deposition. That's the majority of how most of our precipitation forms.
Bone dry. Those Davis stations use Watermark soil moisture sensors. 200 centibars is the dry limit. 0cb is satuated.
So 6" deep is very dry and 12" has a bit of moisture, but is still on the dry side.
Usually you're supposed to pull them in the spring and reinsert them so that there's good contact between the sensor and soil. Freeze/thaw cycles can cause the soil to pull from the sensor with time.
I doubt it trends that far SW leaving us with a heat plume like NNE just saw. I think if you want big heat next week you hope that that trough/ULL is more weak and progressive and scoots right along.
