* Central Idaho Dispatch Area weather impact summary (Zones 475
and 476)...
Widespread clouds remain in place this afternoon with showers and
embedded thunderstorms continuing to move through the region.
Expecting these to increase slightly in coverage over the next few
hours but instability is fairly limited. Today will be the last day
for widespread clouds and precipitation as the pattern will begin to
change tomorrow and especially by Friday. We`ll still see some
scattered precip chances tomorrow, becoming more isolated Friday and
then basically non-existent by the time we get to the Labor Day
holiday weekend and into early next week. Temperatures will slowly
begin to trend upwards once again but not nearly as warm as the
previous week and this will keep RHs above any critical levels into
early next week.
