Amended to add Day 3 to the experiment and to extend the comment

period to April 15, 2017

 

WFO Baltimore/Washington is soliciting comments on the

Experimental Days 3-7 Winter Storm Threat Index through April

15, 2017. The purpose of this experimental product is to

graphically display the location and level of potential

winter storm threats in the extended portion of the forecast 

3-7 days in the future. This threat level will combine winter

precipitation probabilities and potential impact.

 

The experiment received positive feedback last year for days 4-7

and is being amended to include day 3 this year to address

concerns provided through user comments.

 

The experimental Days 3-7 Winter Storm Threat Index graphic also

builds upon data generated by experimental Winter Weather

Outlooks produced by the NWS Weather Prediction Center (WPC).

 

The experimental Days 3-7 Winter Storm Threat Index will be

posted on the NWS Baltimore/Washington winter web page at:

 

http://www.weather.gov/lwx/winter

 

WFO Baltimore/Washington will begin issuing this experimental

product on Tuesday, December 6, at least twice daily at 0900 and

2100 Coordinated Universal Time (UTC) and as needed. No

communication system changes are required to receive this

information.

 

Additional information and an example of the experimental

product are provided at the link below:

page:

If comments are favorable, this experiment will be evaluated for

possible expansion to other NWS offices. An additional

opportunity for comment/review will be provided before a

decision to expand.  If you have questions, please contact:
