Southeast Great Plains Drought Risk

Deep layer soil moisture deficits are generally the result of a long-term dry climate pattern. When long duration (7-10 days) hot and dry weather moves across these regions, quick evolving (flash) drought can generate. These conditions are possible in the southeast Great Plains including Eastern Kansas to Central Oklahoma during late JUL/early AUG.

Extreme Heat ALERT for Late July Great Plains!

The latest 12Z ECM and GFS 6-10-day temperature anomaly outlook is agreeable to developing extreme heat in the central Great Plains. High temperatures reach 100F-105F from the Dakotas to Oklahoma during the period. Using ECM, the peak day is day-10 which is July 31. The 12Z ECM ENS widens the impressive heatwave back into the West, still peaking in the Central U.S., and stretching to eastern North America.

Neutral ENSO Continues, Some Cooling NW Coast of South America

The 2024 daily southern oscillation index (SOI) identifies the uncertainty of direction in ENSO phase. Recently, SOI has spiked highly negative albeit for brief periods. The negative phase is an indicator of an El Nino climate. Conversely, a strong positive spike occurred late JUN/early JUL which indicates a strong La Nina climate. The recent spikes are a new SOI character compared to weaker daily SOI observations of MAR/APR/MAY 2024.

Northeast Pacific Marine Heatwave Helping to Propel Western U.S./Canada Heat

Regions of very warm ocean water known as marine heatwaves (MHW) are commonly linked to high pressure in the upper atmosphere which cause a dry and warmer than normal climate. MHW’s are present and quite strong off the U.S. West Coast and south of the Canadian Maritimes.
