The weather outlook models

We have forecast data from several regional models that cover United States. These models have a higher resolution than global models that forecast for the whole world, but the increased computational demands of a high resolution model mean that these forecasts only go a couple days out in time, and are limited to a small area. We have forecast data from a variety of global models that produce forecasts for the whole world, up to two weeks out in time. Weather models, known formally as "Numerical Weather Prediction" are at the core of modern weather forecasts. All the forecast information you see at weather. Weather models are simulations of the future state of the atmosphere out through time. Millions of observations are used as initial conditions in trillions of calculations, producing a three dimensional picture of what the atmosphere might look like at some time in the future. Massive computers are used to do these calculations at incredibly fast speeds to enable simulations to cover the entire globe, and extend up to two weeks into the future. There are two general types of weather models, global models and regional models. Global models produce forecast output for the whole globe, generally extending a week or two into the future.

Analyzed at 03Z Mon Mar 18, Includes ability to download reports and associated metadata in csv format.

Displays flood and flash flood reports as well as intense rainfall observations for user-selectable time ranges and customizable geographic regions. Includes ability to download reports and associated metadata in csv format. Reports include rain, snow, ice, and severe weather, as well as other significant information from storm spotters. Displays the climatological significance of precipitation forecast by WPC. We are actively working to resolve this problem.

Displays Days NDFD maximum and minimum temperatures, along with their respective departures from climatology. Prototype Snowband Probability Forecasts An interactive tool that depicts areas of heavy snowfall from individual members of high-resolution short range ensemble forecasts. Weather in Context Prototype Displays forecast information and its climatological context to quickly alert a forecaster when a record or neear-record breaking event is possible.

An interactive display of time series plots from GEFS ensemble members at a point. On Monday, the threat of excessive rainfall ends over the Gulf Coast. National Oceanic and Atmospheric Administration. Products include map displays, model-derived soundings, and vertical cross sections. Many charts start at 3 hours ahead, so if you have 0 hours selected try stepping forward or selecting a later hour. These slight differences multiply out through time because the atmosphere is a chaotic system. The hazards associated with these thunderstorms are frequent lightning, severe thunderstorm wind gusts, and a minimal threat of tornadoes and hail. Point A. The circulation around the low will pull moisture off the Gulf of Mexico, aiding in the production of showers and thunderstorms with heavy rain over parts of the Central Gulf Coast.

One advantage to regional models is that they can run at a much higher resolution than global models enabling them to see features such as mountains, valleys, and small bodies of water that would be too small for a lower resolution model to see. The new version is in testing and can be viewed here by selecting 'Parallel'. Ad blocking? The associated heavy rain will create mainly localized areas of flash flooding, with urban areas, roads, and small streams the most vulnerable. This is why the forecast for a week from now is far less accurate than the forecast for tomorrow. Cold Canadian high pressure will ensure winter-like temperatures will be reinforced from the north-central U. No Area. Analyzed at 18Z Sun Mar 17, Point-and-click Soundings.
