U.S. Soil Moisture Outlook

Summer is approaching and soil moisture forecast confidence is lowering. The issue is whether southwest/central U.S. drought expands toward the Corn Belt which is not well supported by models and where the strong Southwest drought goes during summer? NOAA kills all drought areas except the Southwest. So…uncertainty for drought risk in U.S. for summertime but the trend is away from drought east of the Divide.

East Pacific Subsurface Warming Foreshdows El Nino Ahead

Subsurface warming in the eastern equatorial Pacific Ocean is increasing based on NOAA analysis. Implied is the complete demise of La Nina and increasing risk of El Nino the second half of 2018. If so, tropical cyclone activity will be diminished in the North Atlantic basin for this summer.

High Wind Worsens Great Plains Drought

Hot and dry weather worsen drought. What's worse? High wind with dry air. Across the harsh drought zone of Kansas to northwest Texas and cold northwest wind and very dry air arrives this weekend (after today's extreme heat) followed by another warm surge next Tuesday associated with high wind. Models are forecasting sustained wind in the 25-40 mph range for these events.
