  Deep Thunder Forecast for New York

Current Deep Thunder Forecast for the New York State Thruway

Total Precipitation at 16 km between Data Points



Description

This page contains an animation that is a visualization of the Deep Thunder forecast focused on the New York State Thruway.   It uses data from the outer nest at 16 km resolution.   The specific data and representation shown are for potential use for operations and maintenance of highways.   In this case, there are maps of the New York State Thruway, which is color contoured by forecasted total precipitation, accumulated through the 24 hour model run, following the legend at the upper right.   The map is accompanied by a number of overlays, including coastlines in black, state and national boundaries in white, county boundaries in light gray, and cities either by their center or by airport locations in black.   On colder days, a thick light blue line will mark the location of the freezing point of water.

The background of the map shows color contour bands of precipitation (as rain in inches), where brown implies no rain (dry) and heavier rainfall is in darker shades of blue.  If the model predicts no precipitation then a similar visualization of humidity will be shown instead.  If areas where precipitation is forecasted are sufficiently cold, then they may be marked with large or small Xs for snow.  The smaller markers imply light snow or flurries.  In animation, areas of precipitation will appear to "paint" the surface blue.  However, the model calculations require some time to "spin-up" the microphysics to enable precipitation.  Therefore, there will typically be no precipitation in the first couple of hours of model results.  Since the precipitation is accumulated through the model run, regions which stop showing changes in color imply that the precipitation has ended.  In some cases when that happens and the temperature is sufficiently cold, snow markers may appear. This implies that wet surfaces may be beginning to freeze. 





Instructions

The animation on this page is composed of a set of individual JPEG images with one hour of forecast time between each frame.   Depending on your connection speed and that of your computer, the animation may take a few minutes to load and decompress in your browser.   When it is completed, the animation will play.   There are VCR-like controls under the animation to enable you to stop playback, play forward or backward, or step through the frames one at a time, control the speed of playback, etc.   If you are having problems viewing or interacting with this animation, make sure your browser has Javascript enabled.

If the forecast information presented on this page does not seem to be current and you have visited this site recently, the results of the previous visit may have been saved in your web browser's cache. If so, you should change your cache settings (e.g., File->Preferences->Advanced->Cache in Netscape and set the document comparison to "Every time"). When you restart your browser, the problem should be solved. For your current session, you should manually clear the cache and reload the page.
