Current Storm Locations in Colorado:



SIGSTORMS is a program that automatically e-mails out alert messages of new or intensifying convection (especially if near Boulder). This saves the trouble of checking the radar every 15 minutes to see whether storms are firing up. The output of the most recent storm locations (which may or may not have reached e-mailing criteria) is shown above. The area considered by this program includes most of Eastern Colorado and small parts of adjoining states, generally including most of the region within a 280-km radius from Boulder.

The results of a storm centroid locator operating on LAPS radar data are displayed. These include location in azimuth and range (statute miles) from the nearest major town. For locations near Boulder, the township, range, (tshp/ran) and section number are also given. The abbreviations for the towns are as follows:

LIC - Limon
BOU - Boulder
FCL - Fort Collins
COS - Colorado Springs
AKO - Akron

BGD - Briggsdale
STR - Sterling

Storms must exceed a 38Dbz threshold among meeting other criteria to be displayed. LAPS smooths the radar data to a 10km grid before the storms are detected. This typically lowers the peak reflectivites given by about 10 dBZ from the true value. Max Low Level Reflectivity is shown for each storm.

Storms with about 38dBZ (smoothed value) are run of the mill thundershowers. 50dBZ indicates a strong thunderstorm with possible hail. 55+ is typical of potential severe weather, this potential increases as the dBZ exceeds 60.

Automatic e-mail notification:

The SIGSTORM mail messages are sent at appropriate times based on: Maximum Reflectivity, Proximity to Boulder (The Center of the Universe), and time elapsed since the last message (the yawn factor).
