- Injuries and deaths are for the tornado’s whole path, which may extend beyond the county. Deaths recorded within Clearwater County: 0.
- Weak tornadoes were under-recorded before Doppler radar coverage became national in the early 1990s, so earlier decades read low. Ratings use the Fujita scale before February 2007 and the Enhanced Fujita scale after.

- A smoke day is a date on which a smoke plume traced by NOAA Hazard Mapping System analysts from satellite imagery covered this place's point (the county's population centre or the city centre). Counts here are of medium or heavy smoke. Since 2018 analysts have often drawn light smoke as one area over most of the continent, so light-smoke counts are not comparable from year to year. The plumes show smoke anywhere in the air above, not air quality at the ground, and smoke hidden by cloud is missed.

Zero is normal; -3 or lower is severe drought and -4 or lower extreme drought. It describes the long-term balance of moisture, not water supply or crop losses.

- Mar 8, 2003Cold/Wind Chill, South Clearwater$21,000
National Weather Service narrative
A fairly compact ridge of high pressure brought clear skies and brisk west/northwest winds to portions of northwest and west central Minnesota. High temperatures on the 8th were only in the single digits above and below zero. The west/northwest winds of 15 to 25 mph with a few gusts to 35 mph kept temperatures from plunging too far, yet overnight temperatures did drop to 10 below to 20 below zero (or about 30 degrees below normal). This dropped wind chill temperatures to 40 below to 50 below zero for a prolonged period the night of the 8th into the morning of the 9th. With only a few inches of snow left on the ground (mostly in sheltered areas), these extreme wind chill…
