* Central Idaho Dispatch Area weather impact summary (Zones 475
and 476)...
Isolated to nearly scattered thunderstorms are beginning this
afternoon and will continue into the evening as we get another
round of monsoon moisture today. Storm coverage and moisture
increase even more on Wednesday when we expect scattered, WET
storms. Even though they will reach scattered levels, have opted
NOT to issue a Red Flag Warning because of how wet storms are
expected to be. Conditions get drier and warmer Thursday, Friday,
and through the weekend.
* East Idaho Dispatch Area weather impact summary (Zones 410...411
and 413)...
Isolated thunderstorms are forecast this evening and will

today. Storm coverage and moisture increase even more on Wednesday
when we expect scattered, WET storms. Even though they will reach
scattered levels, have opted NOT to issue a Red Flag Warning
because of how wet storms are expected to be. Isolated
thunderstorms will linger through the end of the week as the heat
begins to build again.
