Much Needed Rain in Parts of Texas Hill Country Yesterday

The above image shows the radar's estimate of total rainfall across portions of the Texas Hill Country late yesterday afternoon and evening.  The highlighted red areas indicate where the radar estimates 4-5 inches of rain fell, mainly in rural parts of the indicated counties.

Some of the same activity eventually meandered into the Austin area before diminishing around sunset yesterday, however it had weakened considerably and only produced trace amounts of precipitation in most of that region.

There will be another opportunity for scattered shower and thunderstorm development across the region later this afternoon and evening, along a weak and stalled frontal boundary that roughly runs West to East through the region.    There are also several weak boundaries that were left behind by yesterday's activity that may also serve to focus some redevelopment later this afternoon as well.

The SPC in Norman, OK is forecasting that some of the thunderstorms may become severe on a more organized basis this afternoon or evening, particularly across far southeast Texas (including the Houston area) as indicated by the yellow shaded area on the image below:

The main threat with this activity will be large hail and damaging wind gusts.  Very heavy, beneficial, downpours of rain can also be expected to be concentrated in this region of Texas, which would certainly be welcome...
