Wednesday, according to the National Weather Service in Chicago, which they described as "touching the ground intermittently so far and is moving east."Ī total of eight tornadoes were reported, along with one report of a funnel cloud. A confirmed tornado was on the ground around 7 p.m. The NWS also said a tornado touched down near O'Hare. The National Weather Service confirmed multiple tornado touchdowns in Campton Hills, Countryside, Hodgkins and Huntley. While the storms were powerful, the speed of their movement and what appear to be short bursts of tornado touchdowns resulted in no reports of serious injuries and damage that was often concentrated in single neighborhoods or just one part of a town or village.

Alternatively, a site lower than model orography (Site B) may have forecast wind speeds slightly over-estimated and hence these are reduced slightly in the post-processing.CHICAGO (WLS) - Many are cleaning up after tornadoes and strong storms moved through the Chicago area Wednesday evening, sparking strings of warnings and producing multiple funnel clouds and confirmed touchdowns. In these situations winds may be intensified slightly. If a site is higher in reality than the model orography (Site A), then the wind speed may be under-estimated by the model. National and Local Weather Radar, Daily Forecast, Hurricane and information from The Weather Channel and. This has implications for a range of forecast parameters (including rainfall, temperature, wind speed and visibility), meaning that orographic adjustments need making depending on a specific site elevation. Model orography is usually defined as the average elevation for each grid square. Orographic adjustment of local weather forecastsįigure 2 illustrates taking account of differences between model orography and reality. Get the latest hourly weather forecast, including all weather conditions you need - temperature, precipitation, humidity, and wind - with Tomorrow.ios forecast. This method is often referred to as "intelligent grid point selection", whereby grid points with most similar characteristics to a specific location are given greater weighting in the final forecast. local time, the NOAA Space Weather Prediction Center states.People. This means that forecast temperature and wind speed at Site B would be quite different depending on whether the wind is on- or off-shore. What time will the northern lights be visible The best chance of viewing the aurora borealis will be between 10 p.m. For coastal sites, the weighting between the 'land' and 'sea' values varies with the direction of the wind. Local forecasts for coastal sites can be more difficult to define than inland sites. Site A is likely to be computed from the nearest two land points as it is exactly half way between the two. Coastal adjustment of local weather forecastsįigure 1 illustrates how a local (site-specific) forecast can be computed from a range of surrounding model grid points. Two of the methods are briefly outlined below.

The extracted model data for each location goes through a series of post-processing procedures to make the forecast more specific to a particular location, hence the name "site-specific" forecasts. SATURDAY South winds around 5 knots, becoming west in the afternoon. The site-specific forecasts themselves have to be extracted from horizontal gridded fields for a range of forecast parameters, including rainfall, temperature and wind speed. This means that at any time, the most recent model data is available. They use a "best data" approach, whereby the most recent highest resolution model is used at any given forecast lead time.įorecasts are updated hourly to include the most recent nowcast and any recently updated forecast models. Local forecasts (or site-specific forecasts) are regularly updated and make use of a range of weather models run on the Met Office supercomputer.
