An example of the use of LAPS in convective event
14 May 1999
Location: DEN-BOU WFO
"...for the hourly LAPS soundings, you can go to interactive skew-T, and loop the editable soundings from one hour to the next, and get a more accurate idea of how various parameters are changing on an hourly basis...nice. We continue to find considerable use of the LAPS data (including soundings) for short-term convective forecasting."
Similar over the plains.
Note the strong thermal gradient aloft from NW-S (snowing in southern WY) and the LL moisture gradient across eastern CO.
The omega field has considerable detail (which is highly influenced by topography
