Temperatures
For April through June, warmer-than-normal temperatures are favored for the entire contiguous U.S. with the exception of Western Montana, northern Idaho, and parts of Oregon and Washington. Below-normal temperatures are most likely for parts of southern Alaska, the Alaska Panhandle and parts of Washington state.
Precipitation
The precipitation outlook favors above-normal precipitation for parts of the Midwest, the Great Lakes, the Mid-Atlantic, the Northeast and in Hawaii, while below-normal precipitation is forecast across the southern Plains and much of the West. There is no strong signal to tip the scales one way or another for above or below normal chances of precipitation across the Northern Plains, therefore it is denoted with equal chances.
Drought
Nearly one-half of the country — stretching from the Pacific Coast to the Great Plains and upper Midwest — is currently experiencing moderate to exceptional drought conditions. Warmer-than-average temperatures this spring and low soil moisture will allow drought conditions to develop and expand in the southern and central Great Plains as well as southern Florida. In the northern Plains, existing drought could intensify if subnormal spring precipitation occurs. The map below depicts where there is a greater than 50% chance of drought persistence, development, or improvement based on short- and long-range statistical and dynamical forecasts during March 18 through June 30, 2021.
