A combination of zonal flow in the 1-5-day and 11-15-day period and titanic Southwest U.S. high pressure ridging in the 6-10-day period leaves the west and southwest Great Plains without rain and increasingly very warm in the latest ECM 15-day forecast. Texas to Oklahoma shift wetter in the 16-30-day period while the western Great Plains stay dry and very warm. U.S. hard red winter wheat becomes a hot spot for drought development.

The Climate Impact Company MAR-26 to FEB-28 ENSO phase forecast is based on a constructed analog utilizing upper ocean heat anomalies east of the Dateline, Nino34 SSTA, and southern oscillation index. The upper ocean heat in the eastern equatorial East Pacific became immense during February and is the leading indicator of El Nino risk ahead.

The U.S. weekly evaporative drought demand index (EDDI) valid for late February indicates parts of the U.S. most susceptible to drought or flash drought as the warm season arrives is the Gulf States, parts of the Southwest U.S., and central U.S. Corn Belt. If areas listed shifted into a dry climate as the warm season arrives, rapid drought development/intensification would generate in these zones. However, the U.S. precipitation pattern is forecast to change through the next 30 days featuring above too much above normal precipitation in Texas to the Ohio Valley in the latest 15-day outlook likely to continue in the week 3-4 period.

Reviewing the Climate Impact Company U.S. heating degree day (HDD) count for selected cities reveals the coldest location for meteorological winter 2025-26 was Norfolk, VA where 117.4% of the 30-year normal HDD was observed. Values above 110% are considered MUCH BELOW normal temperature (or MUCH HIGHER than normal heating demand). Norfolk was followed closely behind by New York City (117.0%), Baltimore, MD (114.3%), Richmond, VA (114.2%) and Hartford, CT (113.7%).

-PNA Pattern Rules U.S. Weather Pattern Next 15 Days
The pick of the day climate signal is the Pacific North America (PNA) regime. The 15-day outlook reveals ongoing negative phase into the weekend helping to fuel a Pineapple Express into Washington, shift to positive phase next week causing an amplified upper ridge to roast the Southwest U.S., and return to negative phase sustaining the cool/stormy North and warm/dry South split pattern.

-PNA/+NAO Influences on U.S. Climate
Vigorous positive phase of the North Atlantic oscillation is the lead climate signal supporting the warm pattern across the U.S. during the past 14 days. The negative phase of the Pacific North America (-PNA) has dominated in recent weeks although under-performing as a wet/snowy weather maker in the Northwest/West U.S. while the attendant dry signal for the Southeast is strong.
