BRYAN, Tex. (KBTX) - The winter of "the air is too dry, everything should evaporate before reaching the ground" strikes again. Small hail fell at times Friday afternoon.
A passing disturbance took a perfectly sunny day and covered the sky in mid-to-high level clouds shortly after midday. From those clouds, rain tried to fall from roughly 10,000 feet up.
On any other day, showers that are just a few thousand feet tall would not be able to reach high enough to produce hail or any weather of significance. Combine that with a very dry air mass at ground level and anything that did mange to fall from those clouds typically is expected to evaporate before reaching the ground.
Friday was not any other day...
Hail pea size or smaller manged to fall across parts of the Central and Northern Brazos Valley. Short lived, non-severe, and non-damaging.
Here is the meteorological explanation from the Austin / San Antonio National Weather Service:
"A weak disturbance embedded in southwest flow aloft is allowing for some light showers to develop across the eastern [county watch area]. We have actually gotten some reports of very small hail from this activity which at first seemed quite strange. A quick look at forecast soundings does show some instability from parcels lifted from 660 mb. Even though surface temps are in the middle 60s, dry low levels are leading to much lower wet bulb temperatures. In addition, the appearance of ACCAS on visible satellite this morning also supports the notion that this is convectively driven. The weak instability is allowing for updrafts that develop the small hail and the thermodynamic environment under the convection is then allowing the small hail to make it to the surface."
Below are pictures and videos sent into the KBTX PinPoint Weather Team as this activity passed through Bryan / College Station around 5pm - 5:45pm Friday.
