Hydrologic Outlook issued February 21 at 1:23PM MST by NWS Pocatello ID

ESFPIH

Temperatures will gradually warm this weekend into early next week,
increasing low elevation snowmelt and runoff, potentially leading to
minor lowland flooding. Locations most prone to rapid snowmelt
include areas below 6000 ft across the Eastern Magic Valley, Lower
Snake Plain, and South Hills. In these areas, the increased runoff
on top of frozen or saturated ground may lead to ponding of water or
sheet flooding in low lying or poor drainage areas, along with rises
on small streams and creeks.

These warming temperatures will peak on Monday, with afternoon highs
reaching the 50s at lower elevations. Low temperatures Sunday and
Monday nights are forecast to remain above freezing, prolonging the
melt cycle. While temperatures will remain mild into mid next week,
overnight lows are expected to dip back below freezing by Tuesday
night, slowing the melt. Precipitation chances return to the area on
Sunday, and rainfall amounts up to 0.2 inches in these areas will
add to the runoff.

Make sure drains are cleared and move snow away from buildings to
minimize impacts. Stay up to date with the latest forecasts at
