Temperatures will drop on Thursday as a trough of low pressure moves through the region, keeping conditions breezy and limiting the high temperatures in the valley to the low 70s, but the system is quite dry so it is unlikely we will see any rain out of the deal. After the trough passes through on Friday, skies will clear and the temperatures rebound fairly quickly, moving to the upper 70s Friday, the mid-80s on Saturday and could hit 90 degrees on Sunday. The heat will ease off a bit as we move into the next week, but mostly sunny skies should last throughout.

A plume of ash rises from Kilauea Volcano, one of five on the island, after a series of earthquakes over the last couple of days, in Hawaii

A plume of ash rises from Kilauea Volcano

Yesterday I mentioned that there is no connection between our wet May weather and the eruption of Kilauea Volcano in Hawaii, contrary to what seems to be a lot of chatter on the internet. There are several reasons. Even during its most explosive eruptions, the ash plume from Kilauea stayed well within the troposphere, where it would fall back into the ocean long before travelling this far. To affect weather this far away, it would have to reach the stratosphere. And what winds we do have over there are predominantly trade winds, which blow out of the northeast, which would blow it away from us anyway.
