Hydrologic Outlook
None

ESFPIH Above average temperatures Thursday preceding cold front passage will maintain low and mid elevation snowmelt and runoff. Standing water in typical low spots can be expected, and we'll also likely see swelling in smaller creeks and tributaries that feed larger streams and rivers. This may even push some streams and creeks above bankful causing minor flooding and bank erosion due to the higher flows. Despite cold frontal passage late Thursday, overnight low temperatures will remain above freezing for most areas Thursday night, continuing the runoff. Temperatures Friday and Saturday dip back down toward normals, and overnight lows will be back to near freezing by Saturday morning. This cooldown, however, will be accompanied by increasing rain chances which could add to the runoff concerns. Stay away from fast moving water, swollen river banks, and never attempt to cross flowing water over roadways.
