Temperature and precipitation outlooks for the 6-10 day and 8-14 day periods. Issued daily by the NOAA/NWS Climate Prediction Center. The outlooks express forecast probability that temperatures or total precipitation in the 6-10 or 8-14 day period will tend to be similar to the 10-highest ("above-normal"), middle-10 ("near-normal"), or 10-lowest ("below-normal") observed in the 1981-2010 normals period. Color shading on the outlook maps follows standard convention for warmer/colder or wetter/drier, with near-normal in white. Darker shades of red or blue (or green and brown) indicate a higher forecast probability.

One Month and Three-Month temperature and precipitation outlooks. The outlooks are issued by the Climate Prediction Center on the last day of each month (valid for the following month), with an update to the outlook on the third Thursday of the following month. The monthly and seasonal outlooks are similar to the 6-10 and 8-14 day outlooks. However, in areas where "Equal Chances" (EC) is shown, it means that climate signals do not favor either above- or below-normal, and above-, near-, or below-normal forecast categories are equally likely to occur. A forecast of Equal Chances does NOT necessarily mean forecast conditions are expected to be near-normal.
