.DISCUSSION...
The rest of today through next Thursday...
Isolated showers and thunderstorms, generally east of Billings,
will continue through the evening as energy spins around the low
over the Dakotas. Then, conditions turn warmer and mostly dry into
the weekend under weak ridging.
The next best chance of precipitation arrives Sunday as a
disturbance and associated cold front tracks across the region
late Sunday. Models continue to shift the timing of the
disturbance later, however, increased atmospheric moisture (PWATs
around 120-140% of normal) is expected to move in over the
western mountains by Sunday afternoon, allowing a 30-50% chance of
showers and thunderstorms over the western mountains and foothills
for the afternoon hours. Sunday evening into Monday morning, the
chance of showers and thunderstorms increases to 40-60% for much
of the region. In the mountains, overnight temperatures will fall
below freezing and allow light snow (20% chance of more than 1
inch) over the highest peaks.
For Tuesday and Wednesday, ridging builds in and allows warmer and
mostly dry conditions to return. By Thursday, there are signs of
the ridge beginning to break down although the details are still
uncertain.
High temperatures will be in the 70s Friday, increasing to upper
70s to mid 80s for the weekend. Behind the front, Monday will be
near normal, with highs in the mid 60s to low 70s. Then, as the
ridge builds in, highs will increase to 70s to low 80s for the
middle of the week. Archer
