Well, it won’t go down as the driest January on record. A weak and relatively warm low moving up from Baja California dropped .06” of precipitation on Tuesday, and it looks like that’s probably all we are going to get…not just for the day, but for the month as well. That will tie us for the 7^th driest January on record, should we get no more by the end of the week. A dirty ridge of high pressure builds back into the region, allowing clouds and probably no more to come through. Temperatures will be mild, hanging around the low to mid 50s into the weekend with a clearing expected by Saturday.

Not all clouds are alike.

Whenever we get a dry spell like we’ve had, I get a lot of questions from people wondering why we don’t do more cloud seeding, since clouds haven’t been in short supply. It takes a lot more than just clouds in order to get any benefit from cloud seeding. All cloud seeding can do is increase the yield from a storm that is already producing some precipitation. Tomorrow, I’ll talk about what is needed before cloud seeding does you any good.
