BRO/CRP West Radar Analysis 2240Z

Forecaster comments from EWP blog...

CI continues to show promising results in terms of providing significant lead for strong/severe t-storms.

The first image below at 2115Z shows a strength of signal around 99 (red) in UAH-CI in the upper left pane for a developing storm west of Laredo.
 The next image at 2125Z depicts -14C/15 min UW-CI (lower left) for the developing storm.
Radar imagery continued to show storm growth and the storm reached 50 to 55 dbz at 2208Z as shown in the upper right pane of the image below.  Also, MESH reached 1.18 inches at this time as well.
With these figures in mind, the lead time from initial CI detection on UAH-CI was around 55 min. and the lead time from UW-CI was around 45 min.  It would be great to put a product out conveying the possibility of strong storms when we first see these CI signals with an actual warning coming later.
