  Deep Thunder Forecast for Atlanta

Current Deep Thunder Forecast for the Atlanta Metropolitan Area

Surface Air Temperature and Winds at 2 km between Data Points



Description

This page contains an animation that is a visualization of the Deep Thunder forecast focused on the Atlanta area   It uses data from the high-resolution nest at 2 km resolution.   Each time step corresponds to 30 minutes of forecast time.   The specific data and representation shown are for potential use for short-term weather-sensitive operations and planning.   They show the local terrain as a shaded surface that is colored by contour bands of surface air temperature (degrees Fahrenheit), following the closest scale to the upper right. 

During windy winter days, contour bands of wind chill temperature will be shown instead.  Wind chill is an apparent temperature due to effect of wind on the skin.  In addition, on colder days, a thick light blue line will mark the location of the freezing point of water. 

During humid summer days, contour bands of heat index temperature will be shown instead.  Heat index is an apparent temperature due to the effect of humidity.

The terrain is overlaid with maps of county boundaries in black, major highways in light gray.   Individual landmarks and cities are shown by name with the predicted surface air temperature for that time step.  The map is also overlaid with arrows corresponding to predicted winds.  The arrows point in the direction of the wind and are colored by speed following the further scale to the right.  The faster winds are colored in lighter shades toward white, while the lighter winds are darker in color. 




Instructions

The animation on this page is composed of a set of individual JPEG images with 30 minutes 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.   The mode of playback is controlled via the bottom set of buttons.  Click on the button once, corresponding to the mode of choice (Once: play once in the cuirrent direction; Repeat: play repeatedly in the current direction; Swing: play forward and backward).  The top buttons are used to single step or animate or pause in a forward or backward direction.  The speed of playback can be controlled with the buttons marked Slower and Faster.   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.
