At about 1 AM I heard rainfall. Opening the front door, it was raining and the sidewalk was wet. This is notable for two reasons. First, it was louder than the movie I was watching on TV, so not just a drizzle. Second, because we normally have rainfall end in April.
Now it IS possible to have rain in May, and our average is something like 0.02 inches for the day, so not zero (per Wunderground). The record is from 1905 at 0.87 inches. However, during the last few decades during the warm phase of the PDO it has not been this way. Spring came early, rain stopped early, and it was warm and dry though the spring and summer. Right now we’re looking at drizzle and 54 F temperatures. Wine grapes don’t ripen very fast in cold and dank.
It is my opinion that we’ve moved well into the cold phase of the PDO, things are cooling, and a lot wetter.
On Weather Nation, they are forecasting SNOW for the Sierra Nevada mountains tomorrow and rain along the coast down toward Los Angeles. The map showed what looked like pods of rain over much of Nevada, parts of Arizona, and into New Mexico. So much for an early Summer.
It seems like the whole northern hemisphere is getting extra wet, snowy, and cold conditions; but with an oscillation as waves of the Jet Stream wander back and forth in a meridional configuration. In the late 90s, the jet stream, IIRC, was much more zonal and things were more stable and dry. We’ve now gone back to the more meridional pattern I remember from the ’50s and ’60s.
It’s cold and wet when I’d rather have warm and dry.
On the radio news today they were announcing to “Stay Away from the Merced River”. Why? LOTS of water being released due to the very heavy snow pack and they don’t want dams overtopped. Much of our “water storage system” is full, and being drained, just before summer. Due to a whole lot of snow. Cold snow. Mountains full of it.
This is not the Global Warming I was promised.
