...A Strong Spring Storm will bring Significant Amounts of
Precipitation to the Region through Wednesday...
A complex and slow-moving storm system will bring significant amounts
of rain and snow to Southwest and most of North Central Montana
through Wednesday evening. Snow levels from today and into the
morning hours on Tuesday of 5000 to 7000 feet are expected across
North Central Montana, with 7000 to 9000 foot snow levels across
Southwest Montana. These high snow levels will lead to rain being
the predominate precipitation type over the plains North Central
Montana, valleys of Southwest Montana, and up through the mid-
slopes of the surrounding mountains. Rainfall amounts by Tuesday
morning in these low and mid elevations of 0.25 to 0.75 inches
are currently expected, with the potential for higher amounts
beneath the most persistent bands of precipitation. Snow levels
will then fall Tuesday afternoon and evening to around 4000 to
5000 feet across North Central and into Southwest Montana, which
will lead to a transition from rain to snow. Additional
precipitation amounts from Tuesday afternoon through Wednesday
evening 0.25 to 1 inches are expected across the region, with
some of these values falling as snow. This could make a storm
total of 0.5 to 2 inches of liquid today through Wednesday.
Rain falling on snow during this precipitation event may lead to
significant runoff into area streams, creeks, and rivers. Rises on
area streams and creeks may lead to flooding, especially those
that originate from the mid slopes. In addition, ponding of water
may also occur in low-lying and poor drainage areas.
Those living in flood prone areas should continue to prepare to
mitigate any potential flooding impacts including ongoing basement
flooding. Roads over or near creeks or streams may experience
flooding, while roads near rocky hillsides may see minor rock
slides.
