Subject:   Soliciting Comments until July 30, 2013, on National
           Centers for Environmental Prediction Storm Prediction
           Center Dry Thunderstorm Fire Weather Outlooks for
           Days 4-8, CONUS Only

NWS is accepting comments beginning June 25, 2013, at 1500 Coordinated
Universal Time (UTC), and continuing through July 30, 2013, on
experimental categorical forecasts of dry thunderstorm conditions for
Days 4 through 8.  Web feedback can be provided via an NWS customer
survey link on the National Centers for Environmental Prediction (NCEP)
Storm Prediction Center (SPC) webpage:

    http://www.nws.noaa.gov/survey/nws-survey.php?code=DTFWO

These products are issued once a day at 2200 UTC for the CONUS only.

Operationally the SPC already produces daily categorical forecasts of
critical fire weather conditions from dry thunderstorms for Days 1, 2 and
3; however, federal land management agency Predictive Services Units, NWS
Weather Forecast Office (WFO) meteorologists and other users in the fire
weather community have expressed interest in using longer range outlooks
of dry thunderstorm critical fire weather areas for
Day 4 through Day 8.

Forecasts of dry thunderstorm critical fire weather areas are based on
areas where a combination of numerous cloud-to-ground lightning strikes,
generally less than one-tenth inch of rain and dry fuels are forecast.

The SPC Day 4-8 Dry Thunderstorm Fire Weather Outlooks will be available
as National Digital Forecast Database (NDFD) grids, Redbook Graphics, and
online at:

    http://www.spc.noaa.gov/products/exper/fire_wx/

Additional information is available from the online Product Description
Document:

    http://products.weather.gov/PDD/spc_day38DryT_pdd.pdf

The text Day 3-8 Outlook will also include a discussion of the individual
fire weather areas and conditions.  The AWIPS IDs and WMO Headers for the
Day 3-8 Fire Weather Outlook product suite remain unchanged.

The WMO Headers for the experimental CONUS Day 4-8 Dry Thunderstorm NDFD
grids from the SPC are;

    Day 4 LDIY41 KWNS
    Day 5 LDIY51 KWNS
    Day 6 LDIY61 KWNS
    Day 7 LDIY71 KWNS
    Day 8 LDIY81 KWNS

After the experimental period, a decision will be made to either continue
testing with no changes, revise the test, or make the experimental
product operational.
