Related: About this forumNOAA’s Highest-Res Weather Forecast Yet Is Also Its Most Beautiful
This image, made with NOAAs newest weather model, shows ground temperature readings at a 2 mile resolution. Each pixel is shaded according to the temperature, ranging from 113 degrees F (the brightest yellow) to freezing (white). NOAA
This colorful map of ground temperature shows the tapestry of American weather on September 30. Undeniably beautiful, it owes its rich color gradient to a powerful new scientific tool for modeling the weather for incredibly small chunks of both time and space.
After five years of work, NOAA unveiled the new model, called High Resolution Rapid Refresh (HRRR), on September 30. Like its predecessor, HRRR will update every hour. But, HRRR fine tunes the forecast every 15 minutes by constantly digesting radar reports, so that the hourly update is as accurate as possible. Each forecast starts with a 3-D radar snapshot of the atmosphere that it modifies with data from NOAAs vast network of weather stations, balloons, and satellites.
The added timeliness is important, but where the HRRR really shines is in its spatial resolution. While the previous model could only model the weather in 8-mile chunks, HRRR has a 2-mile spatial resolution. This is important because even a small front can contain dozens of individual storms. Forecasters will have the ability to read the weather on a neighborhood scale, rather than a city-wide scale.
This will let meteorologists and disaster-planners focus on localized weather threats, like tornadoes, hail, or whether that rain-laden thundercloud is going to pass over a neighborhood thats prone to flooding, or one with better drainage. It could also lead to smoother flights by helping pilots and air traffic controllers get a more detailed picture of where turbulence occurs

Very cool! Also interesting is the relative water temps.
People who haven't been to the Carib don't know what beautiful warm waters are...

The map on the site is much more precise as well.

Some Government Agencies Rock and NOAA is one of them.
I wish the COE and FEMA could be restructured from the Top down.
