Prognostic Discussions for 6 to 10 and 8 to 14 day outlooks.
NWS Climate Prediction Center, College Park, MD
300 PM EST Sun November 17 2024

There is no forecaster message written on weekends.

Notes:

Automated forecasts are issued on Saturday and Sunday. Occasionally manual
intervention is necessary to address quality control and consistency issues. In
these cases, forecasts are manually drawn but a full discussion is not issued.

The notation for the categorical forecast indicated on the maps is the same as
that in the tables: A-above   N-near normal   B-below

The temperature map shows regions with > 33% chance of being warmer (orange,
"A"), colder (blue, "B"), or close to (unshaded, "N"). Historical average
values for the calendar period of the forecast (dashes, "f").  Labels on the
shaded lines give the probability (> 33%) of the more likely category (B or A).
 Probability of N is always < 40%.

The precipitation map shows regions with > 33% chance of being wetter (green,
"A"), drier (tan, "B"), or close to (unshaded, "n"). Historical median values
for the calendar period of the forecast (dashes, "inches").  Labels on the
shaded lines give the probability (> 33%) of the more likely category (B or A).
Probability of N is always < 40%.

In the southwest and other climatologically dry regions - there will be a
greater than 33.3% chance of no precipitation and occasionally even a normal
(i.e. Median) value of zero - especially during the dry seasons.  In such cases
a forecast of near normal is effectively a forecast of little or no
precipitation.

The climate prediction center uses 1991-2020 base period means for
temperature...precipitation...and 500-hpa heights as reference in the climate
outlooks.
