.DISCUSSION...

Arrival and passage of a cold front will trigger showers and
some thunderstorms during the afternoon and evening today. The
front stalls across the region Thursday, and more showers and
storms will develop in the vicinity of the front again during the
afternoon and evening. Thunderstorm chances decrease after
Thursday, but showers remain possible through the end of the week
and into the weekend.

Forecast rainfall amounts through Friday range from half an inch
to an inch, which will be beneficial for the area, and may lead 
to some improvements in the ongoing dryness, and thus could reduce
the overall fire weather threat across the area heading into the 
warmer months.
