Hydrologic Outlook issued December 14 at 3:03AM MST by NWS Great Falls MT
Additional Details Here.
ESFTFX Daytime temperatures in the 40s to low 50s and overnight temperatures remaining above freezing will lead to a fairly quick melting of the recent snow across the north-central Montana plains. Soils beneath the snow will initially remain frozen and melting snow may result in standing water in areas of poor drainage and create difficult access to fields and impact some rural roads, particularly where a heavier snow pack exists across eastern portions of north-central Montana. In addition, runoff from recent snowmelt at higher elevations near the continental divide and new snowmelt across the plains may flow into still iced over creeks at lower elevations causing additional issues as water flows over the ice or causes an ice break-up or jam, primarily on smaller creeks. The unpredictable nature of snowmelt and ice on smaller creeks and streams is a situation to be monitored. Additionally, a period of muddy and wet ground conditions may create difficult access in some rural areas. Please report any flooding to local law enforcement and have them relay the report to the National Weather Service.
