         Probabilistic Snowfall Internet Graphical Products in
         the Baltimore/Washington Area Through April 30, 2014

seeking public review and comment on experimental probabilistic
snowfall internet graphical products to be issued as part of the
Pilot Project at the NWS Weather Forecast Office in Sterling, VA,
serving Baltimore, Maryland, Washington, D.C., and surrounding
areas. The experimental probabilistic snowfall forecasts are
available online at:

http://www.erh.noaa.gov/lwx/winter/

These graphics will complement existing NWS "deterministic"
snowfall forecasts, the traditional method of forecasting a
single snowfall accumulation. The experimental graphics will show
the probability of exceeding certain snowfall accumulation
thresholds, along with the "best" (minimum), and "worst"
(maximum) snowfall accumulation scenarios. Taken together, the
graphics will indicate areas of low and/or high uncertainty in
the snowfall forecast.

The experimental forecasts are described in detail, with example
graphics included, in a Product Description Document available
online at:

https://products.weather.gov/PDD/LWX_PDD_SnowProbs_final.pdf

Comments and feedback on this experimental service are
welcomed at:

http://weather.gov/survey/nws-survey.php?code=PSNOWFCSTS

30, 2014. In conjunction with the Pilot Project evaluation, NWS
will evaluate feedback and determine whether to transition the
experimental service to operational status, discontinue it, or
revise and extend the experimental feedback period. NWS also will
evaluate the potential for expansion of this capability to other
NWS offices.
