Cold air funnel clouds are possible in the relatively cold, unstable air mass in place over the Ohio valley today, along with isolated heavy downpours, small hail and an isolated severe storm. Cold air funnel clouds are relatively weak rotations that develop in a relatively cold air mass. They are weaker than normal funnel clouds and rarely reach the ground. However, it is something to be aware of today since they can occasionally reach the ground and cause damage. Cold air funnels occurred Sunday in Indiana.
Localized rainfall…
I began my watering program this week for the first time this year as drought stress was beginning to show itself. Last night, after a day which broke the record for the coolest July 18 high in Cincinnati history, dark clouds developed late and radar indicated some isolated showers.
During the evening, the skies grew dark here and radar indicated a small shower moving slowly into my part of the county. This developed into a small complex of showers which essentially sat in place for three hours pouring rain down on my dry yard. When all was said and done, I had 0.82 inch in my rain gauge. I guess I can turn off the water for a while!
I must be living right!
I checked the radar estimated precipitation and it showed appreciable rainfall over a very small area, and it did not indicate anything as heavy as what I measured. Very localized. Could this be what CoCoRaHS was set up to detect?
It will be interesting to see if there are any other reports of decent rainfall
since there are other CoCoRaHS sites near mine but outside what appeared to be the heavier rain area.
Update: As expected, this was a highly localized event:
