Today through Friday Night...

Today will be a bit warmer than yesterday as temperatures warm
into the 70s to lower 80s under partly cloudy to mostly sunny
skies. Expect it to feel more humid as well as easterly to
southeasterly winds bring a good push of Gulf of Mexico moisture
into the region. This added moisture will stick around through
Friday, aiding the increased chances of precipitation that exist
this evening through Friday. Friday will be another warm and more
humid day as temperatures warm into the 70s to lower 80s with dew
points in the upper 50s to lower 60s (highest out east). Overnight
lows tonight and Friday night will be back near to above normal
in the upper 40s and 50s.

Today`s precipitation chances remain low through much of the day,
with only a few showers and thunderstorms possible by late this
afternoon and evening (10-35% chance). No severe thunderstorms are
expected with the activity today. This activity may continue
tonight into Friday morning mainly across central and eastern
areas (15-50% chance). This activity will bring cloud cover to
the region Friday morning, which may limit the shower and
thunderstorm potential that exists Friday afternoon and evening.
Outside of the potential cloud cover impacts, diurnal instability
and shear, with the passage of a shortwave aloft, will favor the
shower and thunderstorm potential Friday afternoon and evening
(40-75% chance). At this time, it looks like a few storms could
become strong to severe in far southeastern Montana and
northeastern Wyoming during the Friday afternoon and evening time
frame, with the main threat being gusty winds, hail, and brief
heavy rain. Chances of precipitation drop Friday night as ridging
begins to build in for the weekend. Arends

Saturday through Wednesday...

Summer builds back into the area for the extended. Heat builds in
for the weekend with mid 90s on tap for Sunday and lower 90s
Monday. Probability of 100+ degrees is around 30-40% from Hardin
to Forsyth and Miles City Sunday afternoon. Mid 80s to lower 90s
temperatures look to continue through mid week. The next
appreciable chance for precipitation arrives late Thursday into
Friday. Rivers and streams have fallen considerably over the past
week but still have a bit to go to get down to normal summer
flows. If you head out to the rivers to cool down this weekend be
sure to wear life-vests and continue to use extra caution,
especially with children. Chambers



VFR conditions will prevail through this evening. Isolated
convection is expected late afternoon into the evening hours
mainly over the eastern third of the forecast area. Brief MVFR
visibilities can be expected near precipitation areas. Chambers
