Download the Climate Impact Company Week 2-4 Outlook for the U.S.
Pictured: The Climate Impact Company week 4 temperature and precipitation anomaly forecast indicates borderline hot weather in the East and rains to the North-Central U.S.
A strong high latitude blocking pattern dominates the U.S. climate the next 2-3 weeks and keeps much of the U.S. cooler than normal. The blocking pattern pushes the tendency for wet weather to continue but shift to the Northeast States while the great Plains loses the extreme wet events of late April and early May. The ECMWF (model) indicates a progressive Madden Julian oscillation (MJO) to the tropical West Pacific in late May/early June. The MJO will have enough intensity to push a warmer pattern change in the U.S. The warmest temperatures are in the East while wet weather regenerates in the North-Central States. Another excessive rainfall event is possible early June in the Central U.S.
