Unsettled weather this weekend will lead to cooler temperatures
early next week. This should permit continued melting of snow
through Saturday before it begins to slow on Sunday through
Wednesday. There will be two systems producing precipitation this
weekend. Amounts from a fast moving system Saturday will be
minimal but a stronger system Sunday night into Monday will have a
chance to produce accumulating snow in southeast Montana and north
central Wyoming.

The potential for impacts from this melt will continue to be
similar as the previous week: water flowing overland and
accumulating in low lying areas may result in low land flooding,
water flowing over roadways, and basement flooding. Continued
runoff from snowmelt moving into creeks and streams will maintain
the potential for ice jam flooding. Muddy roads may strand
vehicles and impede or cut off travel in some rural areas.

Southeast Montana high temperatures in the upper 40s to lower 50s
with low tempeatures around 30 will cool to highs of 40 to 45
with lows in the upper 20s by Monday. This transition will slow
the rate of snow melt but snowpack temperatures have warmed enough
for a persistent melt to occur. The heaviest precipitation Sunday
night and Monday is expected to fall as snow, so it is not
expected to immediately contribute to water problems.

If preparations have not already been made, now is the time to
move equipment and livestock out of low lying areas, and away from
waterways. Move heavy accumulations of snow away from home
foundations, and take steps to prevent water making it into

local law enforcement and ask them to pass it on to the National
