.DISCUSSION...A few rain showers are still possible this
afternoon. Wetting rain is unlikely unless an especially strong
shower develops over the higher terrain. Thunderstorm chances have
diminished, but still hold at around 5%. Rain chances decrease
Saturday, but another passing system on Sunday could bring a few
showers to the area once again. Conditions will dry out early next
week. The next possible chance of rain will be from moisture
streaming northeast from a decaying tropical system mid to late
week.
