Description: This report examines three extreme weather phenomena in December 2020: Continuing drought in the Western United States, heavy precipitation, snowfall, and flood in the Eastern U.S., and ranking 2020 global land and ocean temperature vs previous annual averages of the last 141 years.

Description: Actuarial Weather Extremes: November 2021 Extreme Precipitation, Drought, and Late Season Tornadoes This report examines weather conditions for precipitation, drought conditions, and late season tornadoes that are extreme in an historical context. Extreme Precipitation in the Pacific Northwest: Many Global Historical Climatology Network (GHCN) stations in Northwest Washington state and Southwest British Columbia had record November daily precipitation amounts on November 14 and 15, 2021 when looking back to 1960. During and after those dates, many U.S. Geological Survey (USGS) stream gage stations in Washington had readouts that were from Flood Stage to Major Flood Stage. Drought Conditions increase in Continental U.S. as Drought Moves East: Severe drought conditions in the Western U.S. dissipated somewhat, but in the Continental U.S. as a whole, the footprint where drought conditions exist has increased overall, and is driven primarily by increased drought in South-central and Middle Atlantic states. Late Season Tornado Activity: Comparing the historical database of tornado activity and the recent activity in the state of New York, of 24 November tornadoes reported in New York since 1950, nine occurred on November 13, 2021. These late season tornadoes are rare in New York, and November 2021 was exceptionally active for these storms.
