* Central Idaho Dispatch Area weather impact summary (Zones 475
and 476)...
Winds will be lighter today with winds becoming fairly stable
heading into mid to late week as high pressure begins to take
control of local weather once again. RHs will increase today
with slightly cooler temperatures but begin to trend drier
again starting Wednesday as weak high pressure slowly takes hold.
Precipitation chances look bleak for much of the week although
some isolated high terrain showers/storms could transpire over
the days ahead, chances are low. The weekend looks increasingly
dry with warming temperatures as the region will be on the
western edge of a potent area of high pressure well to our east.
This will likely lead to multiple days of critical RHs but winds
don`t look to be too problematic during this period but it will
certainly be hot and dry.
* East Idaho Dispatch Area weather impact summary (Zones 410...411
and 413)...
