The National Blend of Models (NBM) is a nationally consistent and skillful suite of calibrated forecast guidance based on a blend of both NWS and non-NWS numerical weather prediction model data and post-processed model guidance.

The first version of the NBM was released January 6, 2016 in CONUS AWIPS 16.1.1, after Congress mandated that the NWS develop a blended model approach following Hurricane Sandy in 2012. This first version used 3 models (GFS, GEFS mean, CMCE mean) and covered temperature, wind, and sky cover over the CONUS (Continental United States) region two ...

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.

The National Blend of Models (NBM) is a nationally consistent and skillful suite of calibrated deterministic and probabilistic forecast guidance based on a blend of both NWS and non-NWS numerical weather prediction model data and post-processed model guidance.

Welcome to the National Blend of Models (NBM) dashboard. This serves as a summary of the various model inputs fed into each run of the NBM at a range of projections out to 11 days (264 hours) given date and cycle, region, and weather element.

1. Medical-grade micropore design, fine atomized granules, more full drug absorption.2. Obtained the US FDA, EU CE authority certification.3. Piezoelectric component low noise design, more quiet.4. Made of non-toxic and safe materials and passed biocompatibility test;5. Independent atomizing component design, easy to c

NBM forecast date/time extends out 10 days. The time is dependent on the forecast variable. You can display a range forecast, which by default displays the 10th percentile, mean and 90th percentile (you may switch from the mean to the deterministic forecast by clicking that option).

NEW NBM v4.1 Weather Elements (1) Added NBM 24h PQPF percentiles (5th, 10th, 25th, 50th, 75th, 90th, and 95th) for the Hawaii domain. Added CONUS, Alaska, Hawaii, and Puerto Rico NBM QMD PQPF percentile guidance (10th, 50th, and 90th) for 48h and 72h periods with moving 12 hour windows through projection 108, then 24 hour windows through ...

These are the weather elements available in NBM v4.1, the regions they are available, and their definitions. Weather elements new to NBM v4.1 are marked with an * . Regions available are marked by x in a the region column. The regions are: CONUS (CO), Alaska (AK), Puerto Rico (PR), Hawaii (HI), Guam (GU) and Oceanic (OC).
