.DISCUSSION...A slow moving ill-defined front will move into the
region tonight. This system will work with the monsoonal moisture
over the region to develop scattered thunderstorms this afternoon.
These storms will persist into the evening and perhaps even
linger through the overnight hours. Models showing quite a bit of
cloud cover on Sunday which may help to keep temps a few degree
cooler. Otherwise isolated thunderstorms will once again be
possible on Sunday and Monday as the front stalls over southeast
Idaho. Best chances for isolated storms will be across the Snake
Plain and eastern highlands. Drier air will work into the region
for Tuesday and Wednesday, but it looks like monsoonal moisture
could return to the region by the end of the week.
