| Digital Wind and Wave Forecasts on Inland Lakes and Reservoirs | Wind and wave digital forecasts on inland lakes and reservoirs in text
and graphical forecasts on the WFO web page. Wind and wave forecasts
created within the GFE using the NOAA/GLERL wind/wave model.WInd wave
forecasts for the lakes are produced using forecaster derived data. |
| Dry Lightning Potential Index | The Dry Lightning Potential Index (DLPI) is a graphical product
produced by forecasters at WFO Las Vegas (VEF) using GFE/IFPS.
Ratings of Dry Lightning potential (numbered from 0 through 6) for
the next three days (today, tomorrow and the next day) are calculated
using forecasts of boundary layer relative humidity and static
stability. The DLPI is intended to be used as general guidance,
primarily for planning purposes. The DLPI is intended as a seasonal
product, issued from June through October, when active wildfires are
most likely to occur in our forecast area |
| Eastern Pacific Hurricane Season Outlook | The Climate Prediction Center (CPC) issues the Hurricane Outlook for
the eastern Pacific east of 140? West. No outlook, however, can give
certainty as to whether or not a particular locality will be impacted
by a tropical storm or hurricane in any given year. CPC issues this
outlook in cooperation with the Tropical Prediction Center and NOAA?s
Hurricane Research Division. |
| Eastern Region National Digital Forecast Database (NDFD) Graphic Forecast Displays | The National Oceanic and Atmospheric Administration (NOAA) National
Weather Service (NWS) National Digital Forecast Database (NDFD)
Graphic Forecast Displays
(http://www.erh.noaa.gov/ndfd/graphical/sectors/ccc.php)where ccc is
the WFO ID, are web-based presentations of digital forecast data
originating from local Weather Forecast Office (WFO) digital
databases. The data is displayed in a graphical form on a local
scale. |
| El Nino/Southern Oscillation (ENSO) Diagnostic Discussion | The Climate Prediction Center (CPC) issues this monthly bulletin to
provide insight into climate outlooks by reviewing the potential
effects of the ENSO. |
| Enhanced Product addition of Max Wind-Hail Size Coding Tag for Severe Thunderstorm Warnings and associated follow up sta | The Central Region Severe Thunderstorm Warning (CR SVR) is an
alphanumeric product providing short-fused warning in¬formation on
hazardous conditions associated with thunderstorms which are expected
to pose a threat to life and/or real property. This product is
prepared by each National Weather Service (NWS) Weather Forecast
Office (WFO) for their County Warning Area (CWA) of responsibility.
Integrated Warning Team workshops, as well as several societal
impacts groups, have indicated a desire by many emergency managers
for a concise tag line on the end of the SVR product identifying
maximum hail size and wind speeds expected for a given SVR warning.
Local area sirens are typically alarmed for tornadoes only. Decoding
this tag line will facilitate the capability for local area EMs to
trigger sirens for particularly dangerous severe thunderstorm events
when conditions exceed locally developed thresholds for thunderstorm
induced wind and or hail size. |
| Enhanced Product National Implementation of the use of 1 inch Diameter Hail Criteria | The Severe Thunderstorm Warning (SVR) is an alphanumeric product
providing short-fused warning in¬formation on hazardous conditions
associated with thunderstorms which are expected to pose a threat to
life and/or real property. This product is prepared by each National
Weather Service (NWS) Weather Forecast Office (WFO) for their
County Warning Area (CWA) of responsibility. In the Western Region
(WR) and Central Region (CR) a Severe Thunderstorm Warning is
currently being issued experimentally based on expectation of winds
gusting to 58 mph or greater and/or hail of one (1) inch diameter or
greater. Pending successful completion of this experiment, all NWS
sites will issue Severe Thunderstorm Warnings based on these
criteria.
|
| Enhanced Winter Weather Guidance Product Suite | The Hydrometeorological Prediction Center (HPC) proposes to produce
probability guidance for three specific snow/sleet accumulation
thresholds per forecast day out to Day 3. HPC will also generate
separate probability graphics for the exceedance of freezing rain.
In addition a single graphic will depict both HPC forecast position
of significant surface low pressure centers over the contiguous U.S.
and conveyance of uncertainty of the forecast position. This will be
depicted in 12 hour increments out to Day 3. |
| Enhancement to the National Snow Analysis: Experimental NOHRC Snow Model and Forecast Products Expansion | The NOHRSC is expanding the spatial domain of its gridded snow model
into Canada to include the Great Lakes drainage area. Additionally,
the NOHRSC is executing the model in a 72-hour forecast mode. The
Rapid Refresh (RR) model forces the first 18 forecast hours and the
North American Mesoscale (NAM) model forces the remaining 54 forecast
hours. |
| Ensemble Trace plot | Currently the National Weather Service (NWS) River Forecast Centers
(RFCs) and Weather Field Offices (WFOs) produce a wide variety of
river forecasts, which indicate current and future river conditions.
The Ensemble Trace Plot prepared by the North Central River Forecast
center (NCRFC) will be issued as a Web page graphic. The graphic
will be for the NCRFC?s area of responsibility. It will be issued
once a month (after the Climate Prediction center (CPC) outlooks are
released at mid-month). It will cover the three month period after
the issuance (for example, graphic released around May 26 will cover
June-August period). |
| Expected Value plot | Description: Currently the National Weather Service River Forecast
Centers and Weather Forecast Offices produce a wide variety of river
forecasts to indicate current and future river conditions. The
Expected Value graphic indicates timing and confidence levels for
forecast stages for a selected time-frame, generally 90 days. This
would provide an overall range of expected hydrologic conditions
based on computed probabilities. The Expected Value Graphic will be
issued as a web-based graphic for NCRFC?s area of responsibility. It
will be issued once a month after the Climate Prediction Center
outlooks are released at mid-month to cover the ensuing three month
period (i.e. graphic issued around May 26 will cover the period from
June-August). |
| Extended Convective Forecast Product (ECFP) | Automated probabilistic 24 hour thunderstorm outlook based on SREF
Calibrated thunder guidance. This automated graphical forecast is
created from the Short Range Ensemble Forecast (SREF) Calibrated
Thunderstorm output. Contours are drawn at 40, 60, and 80%
probability of “thunderstorm” (not convection) using CCFP-like
shading. Hashed areas represent 40-59% probability, solid lined areas
represent 60-79% probability, and solid blue filled areas represent
greater than 80% probability. The automated graphic uses the 09Z
initialization of the SREF valid for 18Z-00Z the next day |
| Extreme Wind Warning (EWW) | The Extreme Wind Warning (EWW) is a text product prepared by the
National Weather Service (NWS) Weather Forecast Offices (WFOs). The
product warns of imminent or impending extreme winds associated with
a landfalling hurricane. |
| Fire Weather OutlookElements in National Digital Forecast Database (NDFD) | Two digital data elements in the NDFD, and associated web imagery,
forecasting fire weather conditions, originating from the Storm
Prediction Center:
- Fire Weather Outlook Critical/Extremely Critical Areas (Days 1-7)
- Fire Weather Outlook Critical Areas for Dry Thunderstorms (Days
1-3)
|
| Fire Weather Planning Forecast (FWF) Text Format | Customer feedback from the Pacific Northwest test in 2011 was all
positive. Based on those responses, the test has been expanded to
include all WFOs in Western Region optionally, based on office need
and customer concurrence. Each office that chooses to test this
format in 2012 per the dates above will issue their own Service
Change Notice.
This FWF text format utilizes left-justified asterisks to begin each
line of text. The asterisks help maintain proper word wrapping and
indentations in the AWIPS text editor, significantly reducing the
amount of time needed to post edit the product before dissemination.

| Fire Weather Point Forecast Matrix | Land management agencies in Georgia and North Carolina have expressed
a need for easily accessible tabular forecast data that is tailored
toward fire behavior applications. A fire weather version of the
Point Forecast Matrix (PFM) table fits this need well because it
allows agency specialists to quickly run simple fire behavior models
for planning purposes. The product is called the Fire Weather Point
Forecast Matrix (PFW) and is generated routinely for the National
Fire Danger Rating System (NFDRS) sites or other areas as determined
by the users. This additional data will help land management agencies
to ensure the safety of fire crews as well as better plan prescribed
burns and other projects in a cost and resource effective manner.
Also, land managers have expressed a need for better tools to predict
and manage smoke dispersion. They have also requested that the NWS
include an Atmospheric Dispersion Index (ADI) and Low Visibility
Occurrence Risk Index (LVORI) in the PFW product.
WFO Fire Weather PFW’s are generated for the Remote Automated Weather
Station (RAWS)/NFDRS sites using an edited version of the standard PFM
formatter. This formatter produces needed fire weather parameters from
the local WFO’s Digital Forecast Database (DFD). PFW's can be
generated for any grid point in a DFD based upon user request. The
web delivery of the product for fire weather customers will include a
disclaimer at the top of the page stating “This product is for
planning and review purposes only and is not to be substituted for an
official fire weather spot forecast. The data displayed are calculated
from a 5.0 by 5.0 km digital database and only approximates weather
conditions in highly varying terrain. Please relay any comments you
have to your local NWS office.
An example of the PFW can be seen at:

| Fire Weather Threat 4-Panel Graphic | The Fire Weather Threat 4-Panel Graphic displays on the Internet
several parameters that are critical for fire weather. In the upper
left corner of the graphic is a ?Red Flag Risk Index? based on
forecast minimum relative humidity (RH) and forecast maximum
sustained wind. In the upper right hand corner is the Red Flag Risk
Index for the current hour based on the GFE RH and wind observation
database. In the lower left corner is the Haines Threat Index based
on the forecast high level Haines Index and forecast minimum relative
humidity. A second graphic is available based on the Forecast Haines
Index and the current relative humidity from the GFE observation
database. In the lower right hand panel three graphics reside. The
probability of 25% or lower RH, 15% or lower RH, and the current
observed RH. |

at the day five period.
|
| Flash Flood Potential Index | The Flash Flood Potential Index (FFPI) is a text product produced by
forecasters at the WFO SGX and WFO LOX using objective forecasts
techniques based upon model data. Ratings of flash flood potential
(numbers 0 through 4) for the next two days (today and tomorrow or
tomorrow and the next day - depending on the issuance time) are
calculated using precipitable water, winds aloft (700 mb), and
forecaster knowledge of other atmospheric factors such as stability
and atmospheric capping. The FFPI is issued during flash flood season
from June 1st through September 30th.
|
