About NBM v4.0 Text Bulletins

The NBM text bulletins take data from the gridded NBM forecasts and generate data for weather stations from the closest usable grid point. Bulletins are available for over 9,000 land and marine stations in the CONUS, Alaska, Hawaii, Puerto Rico, Guam, and Oceanic-domains. Not all elements may be available for all stations. All regions (including both land and marine stations) are included in the same product.

There are five NBM text bulletins, which cover different time scales and different elements. The products are as follows:

(*Actual forecast hours change according to cycle. Listed times are for 00Z and 12Z cycles.):

Product Name Product Type Time step Forecast Hours covered
NBH Hourly 1-Hourly Hours 1-25
NBS Short 3-Hourly Hours 6-72*
NBE Extended 12-Hourly Hours 24-192*
NBX Super-Extended 12-Hourly Hours 204-264* (continuation of NBE)
NBP Probabilistic (Extended period) 12-Hourly Hours 24-228*

Example bulletins for each of the types (NBH,NBS,NBE,NBX,NBP) are listed below. At the bottom of the page, additional stations from different locations are displayed to show expected data at different regions (and at land vs. marine stations).

The bulletins consist of the following:

  • The first line always consists of: the station call(short name), bulletin name, forecast date, and forecast cycle.
  • The following 2-3 lines show the forecast valid date/time and/or model forecast hour. All forecast dates and times are listed in UTC time.
  • The lines following the date/time consist of various weather elements. These elements vary by bulletin type, region, and sometimes cycle. 
  • Large values: any value which would be printed as >998 will be printed as 998 (except MSLP: see element description below for details)
  • Large negative values:  Any element with a displayed value < -98 will be displayed as -98.

Missing Data:


For all Elements, a value of -99 indicates missing data. If data are missing for all forecast hours, the line for that element will not be printed. [NOTE: This is different than previous versions, where missing data was listed as 999 ] 

Changes from NBM v3.2 Text Bulletins

Users should take note of the following changes from the NBM v3.2 products:

  • Approxamately 3000 new stations have been added to the station list, and co-located stations have been removed. For more details on the stations with NBM text data, please see the NBM v4.0 station table. 
  • Missing elements are now denoted by -99 instead of 999. This change is for better readability. (Values with display number >998 will still be listed as 998 to avoid confusion. Values < - 98 will be displayed as -98.)  
  • Unlimited visibility/ceiling elements are now denoted as -88 instead of 888 for better readability.
  • New elements have been added. New elements are listed in bold and marked with an asterisk (*).
  • Some elements have changed format, position, and/or name. These elements are marked with a double asterisk(**).
  • The positions of many elements have changed. Please read the key for current data order and format.
  • The size of the NBE bulletin has been increased slightly from 72 to 73 characters per line for better readability.
  • CLIMO data for Tmax and Tmin has been updated for CONUS and AK, and a QPF climatology has been added
  • Major cycles for bulletins have changed. They are now centered on 01z, 07z, 13z, and 19z

CLIMO

Climatology data for select stations are displayed under the CLIMO column. These include: daily maxiumum and minumum temperatures (TXN), 12-hour PoP from 00z-12z and 12z-00z (P12), and estimated weekly total QPF (Q24)These are all calculated from monthly datasets and interpolated to expected values at Day 4 (middle date). 

  • For QPF, an estimated Weekly Total precipitation was calculated from PRISM climatological monthly mean precipiation totals for 1981-2010 (CONUS) and 1971-2000 (Alaska).  
  • For temperatures, the climatological daily maxiumum and minium were calculated from PRISM climatological monthly maxiumum and minuimum temperatures for 1981-2010 (CONUS) and 1971-2000 (Alaska).  
  • For PoP 12, the CLIMO displays the normal observed relative frequencies of 0.01 inches or more of precipitation during the 96-108 and 108-120h (00z) or 84-96 and 96-108 h (12Z) periods calculated from the climatological norm for the 1971-2000 NCDC data for Day 4. The technique generating these climatologies is the same as for MEX bulletins, and detailed information can be found in MDL TPB 05-07. (This is the same dataset available for CLIMO in NBM v3.2 text products.)

About Probabilistic Elements

The weather elements for NBP are probabilistic percentiles. For X percentile, there is an X% probability that the weather element will be EQUAL TO or BELOW the value listed (or a (100-X) % chance the value will be above what is listed). So for 10th percentile, there is a 10% chance the value will be at or below the number listed, and a 90% chance it will be above. For additional information about NBM weather elements, see the Element Key
