Subject:   Soliciting Comments on the Storm Prediction Center
           (SPC) Experimental Categorical Day 1-3 Convective
           Outlooks through June 17, 2014

NWS is seeking user comments on the SPC experimental Categorical
Day 1-3 Convective Outlooks through June 17, 2014. Examples of
these Outlooks, using historical data, additional information,
and a link to provide user comments are online at:

and via the Product Description Document:

The Experimental SPC Day 1, Day 2 and Day 3 Convective Outlooks
for the Continental U.S. will include two new risk categories:

 - "Marginal" replaces the current SEE TEXT used in these
 - "Enhanced" is an additional category to delineate areas of
   risk in the high end of the current SLIGHT risk, but below
   MODERATE risk.

This proposed change is based on partner and user feedback and
the need to provide better consistency with other NWS products.

With the addition of "Marginal" and "Enhanced" categories, the
following categories are included:

 - General Thunderstorms
 - Severe Category 1 - Marginal
 - Severe Category 2 - Slight
 - Severe Category 3 - Enhanced
 - Severe Category 4 - Moderate
 - Severe Category 5 - High

Probabilities associated with the existing risk categories
SLIGHT, MODERATE and HIGH are essentially unchanged (with the
exception of the high end probabilities of the SLIGHT risk
category which are now called Enhanced).

Comments will be accepted through June 17, 2014, online at:

Based on feedback, the experimental products will transition to
operational, be discontinued, or be adjusted and resubmitted for
another comment period.
