A low pressure center moving through southern California will bring us a couple more days of unsettled weather across western Nevada. Southerly flow from the low will bring up enough moist and unstable air to keep us mostly cloudy with scattered thunderstorms Wednesday, and will keep us with a chance of the same Thursday. High temperatures will stay on the cool side of average (upper 60s Wednesday and low 70s Thursday.) A break in the action occurs on Friday and while an isolated shower isn’t out of the question over Memorial Day weekend (remember…it IS Memorial Day), it looks like temperatures should warm up to seasonable levels by the holiday.
Many are wondering if it’s time to turn the swamp (evaporative) coolers back on. My initial response is “sure… why not?” As we move through the middle part of May it becomes less likely that we will get any freezes hard enough to do any damage to the units. The only downside is it could still get cool enough at night so that the house may get chilly as the cold air bleeds in through the open vents. But if you don’t mind that, it should be safe to get them ready.
