...Much drier air begins to filter into the region today as low pressure drifts through the northern Great Basin heading into the weekend. Some remnant moisture over the eastern zones may lead to scattered showers and thunderstorms for one more day, but that is about it.
These remnant chances are gone over the weekend as dew points drop into the lower 20s. Expect crisp and cool weather, due to overnight lows falling into the 30s. Daytime highs will remain at or just above normal.
