Days 1-7 and 7-14 QPF and % of normal for these amounts for days 1-7

present the likelihood of receiving a precipitation total that differs significantly from normal. For precipitation, green areas denote parts of the country with an increased chance of being in the wettest tercile, or the wettest third of historical data. Similarly, brown areas denote parts of the country that are projected to have an elevated chance of being in the driest tercile. Where neither color is shaded, CPC has concluded that there is no strong signal to determine an accentuated chance of being in either the driest or wettest tercile. This does not mean that near normal precipitation is expected, but simply that the 3-month period is just as likely to be in the wettest tercile as it is to be in the driest tercile.
