Places in the Lower 48 states where the forecast for May 2021 favors a much colder than usual May (blue colors) or much warmer than usual May (red), or where the probability of a cold May, a warm May, or a near-normal May are all equal (white). The darker the color, the stronger the chance of that outcome (not the bigger the departure from average). NOAA Climate.gov map, based on forecast data from NOAA CPC.
