Area Forecast Discussion
National Weather Service Boise ID
253 AM MDT Sat Jul 5 2025

.SHORT TERM...Today through Monday night...The final piece of
the trough that brought the strong to severe thunderstorms
yesterday will exit the area to the east this morning. Behind
that, we will see mainly zonal flow through Monday morning as a
ridge begins to build in from the southeast. Our upper flow will
turn a little more SW Monday afternoon into Monday night, and
this will increase temperatures notably. Highs today will be
around 5 degrees below normal, rise to near normal Sunday, and
then get to 5 to 10 degrees above normal Monday. No
precipitation is expected for most areas throughout the short
term. The only exception is a slight chance of showers and
thunderstorms today in northeast Valley County.

.LONG TERM...Tuesday through Saturday...Strong model agreement
continues to favor a large ridge building into the area off the four
corners region Tuesday and Wednesday, returning higher than normal
valley temperatures into the lower 100s on Tuesday and the upper 90s
Wednesday. The ridge interacting with a closed upper low off the
California coast continues the possibility of steering some
monsoonal moisture throughout the week. Wednesday and Thursday will
see the low breaking off into a trough that will dig across the
area. Guidance uncertainty remains on the potential moisture
and precipitation brought by this system. Strong ridging from
the four corners region is expected to build back into the area
Friday into Saturday.
