The most serious problem with cloud seeding is that, at best, it can increase rainfall by roughly 10% over what would have fallen anyway. Meaning, if zero rain would naturally fall, seeding cannot help.
Here is the weather satellite photo with 5pm temperatures. Some areas have had highs above 115° this afternoon. See any rain clouds in the Kansas portion of the photo (where the cloud seeding program is conducted)? Even though rain is desperately needed, there are zero clouds to seed.
Cloud seeding, outside of mountain areas, where the meteorological dynamics of rain and hail are very different has been controversial since its beginnings. I’ve never had any problems with cloud seeding but I question whether the cost/benefit of the additional rain and lessened hail is sufficient for it to continue.
This type of billowing cloud, when it occurs in the afternoon or evening, is usually precursor of thunderstorms later in the day. The thunderstorms do not always occur at the same site billows. They usually occur within about 50 miles.
The radar (2:35pm CDT) is currently blank. I’ve drawn a 50 mi. radius circle. So, let’s check back and see if this forecast is validated.
You don’t want to fly through these, they are highly turbulent. They were photographed on December 10. The air currents are blowing like waves on water and an airplane would be lifted and dropped accordingly.
I’m in State College for the American Meteorological Society’s Summer Meeting. I was on my way to McD’s (State College is a Pepsi town) to get my morning fix of Diet Coke when I looked up in the parking lot to see the jet plane’s condensation trail cutting through the cirrocumulus clouds (click on photo to enlarge). The soot particles attract the moisture from the ice crystals that make up the cirrocumulus clouds causing the ice crystals to dissipate.
