DISCUSSION

The upcoming forecast remains so stable, that one could really just say "see previous discussion" and call it a day. Forecast changes are so minor as to be non-existent. High pressure stays in place for much of the upcoming week, keeping warm and dry conditions across East Idaho. Temperatures look to be warmest on Sunday, and may approach record highs in some locations. Ensemble means still try to swing a weak shortwave to the north Monday into Tuesday, but forecast remains dry overall.
