Wet Soils To Suppress U.S. Summer Heat

A very hot summer 2018 was foreshadowed by a widening dry-to-drought condition. This year widespread record wet soils are evident in the Central Plains, Midwest and East U.S. The soil moisture regime foreshadows a borderline anomalous hot summer ahead.

Dynamics of Tropical Cyclone Idai

Once again a large "blob" of much warmer than normal ocean water in the tropics/subtropics increased available energy to cause a tropical cyclone to flourish and intensify while moving slowly to cause maximum damage due to a blocking subtropical ridge pole ward of the storm.

Oncoming El Nino (Persistent Negative Southern Oscillation) Lead to Wet FEB/MAR Pattern in U.S.

The atmosphere finally coupled with the equatorial East Pacific warming the past 7 weeks as demonstrated by a persistent negative phase of the southern oscillation index. The evolving El Nino climate helped to inspire heavy precipitation events.

Explaining High Wind Events Across The Central U.S.

From Kansas to Indiana 8-9 seperate days of wind gusts exceeding 40 mph have occurred since February 1st. Included are wind gusts exceeding 70 mph (in non-tornado events). A much stronger than normal jet stream is contibuting to this regime which continues into April.

Polar Vortex ALSO Causes Late Winter Heavy Precipitation

An intense high level atmospheric polar vortex developed during late winter. Strong positive arctic oscillation identifies the presence of the strong polar vortex. The polar vortex pattern caused extreme temperature the past 30 days in the U.S. BUT ALSO the excessive precipitation leading to early spring flooding.

Soaking Wet U.S. Soils Leads To Immense Spring Flood Risk

U.S. flood risk is increasing steadily due to historic wet soil moisture, heavy precipitation events and snowmelt. Worsening flood conditions evolve during spring.

Another Severe Weather Outbreak

Another severe weather event is unfolding in the Mid-South U.S. This one will not be as violent as observed in Alabama earlier this week but still packs a punch. Tornadoes are likely today in Arkansas to Tennessee to Mississippi.

Wettest Winter on Record in U.S.

The U.S. has just observed the wettest meteorological winter in the 1895-2019 period of record. Partially to blame is historic warmer than normal oceans.

The Southeast U.S. March 3 Tornado Outbreak

A combination of an intense jet stream flow coupled with an unusually warm Gulf of Mexico lead to an unusually intense tornado outbreak in the Southeast U.S. on March 3rd.

The Coldest Weeks Compared to Normal This Past Cold Season are in November and March

Using weekly gas population weight heating degree day anomalies the coldest weeks of the 2018-19 cold season occurred early (November) and late (March).
