Take a look at the radar image of east AR early this afternoon, shown below. The topography is underlaid on the radar data and Crowley's Ridge is indicated by the dotted orange line. What do you know? Showers formed along Crowley's Ridge! If you were to look at a loop of the radar data, you would see them form over the crest of the ridge, then move north-northeast in the direction of the winds at 10,000 feet, which is why it rained downwind of the ridge! That extra 400' or so of "lift" created by the ridge induced small showers to form! In fact, later this afternoon, cumulus clouds had formed once again right down the spine of the ridge (see second image below).
|Showers formed over Crowley's Ridge, then moved NNE - the direction the wind was blowing at about 10,000'|
|Cumulus clouds, caused by warm temperatures, sufficient moisture, and a little "lift" from Crowley's Ridge, are visible in this satellite image over east AR.|
