Shades of blue and red show the chances of an unusually wet or dry spring (April-May) in 2019. "Unusually wet or dry" means seasonal average temperature in the top or bottom third of the climatological record (1981-2010). Darker colors mean higher chances (greater confidence in the forecast), not how warm or cool the conditions will be. NOAA Climate.gov map, based on data from the Climate Prediction Center.
