Could be an active weather day ahead, so keep a keen eye one storms, possibly severe developing this afternoon into the overnight hours. The Storm Predication Center has Updated their Day 1 Convective Outlook to now include much of our Region in Slight Risk for Severe Thunderstorms. Damaging winds and large hail are the primary threat.

Potent line of storms around Madisonville and scattered popcorn feeder showers around Houston.

Largely a bust so far here. Juicy air, heavy clouds...but no rain.

PW's east of here and towards Houston 1.8+. We'll see.

Just had a quick shower here in Stafford. Just enough to make it hot and steamy outside.

I think that band entering Harris County from the SW might be messing with our planned grill time :( :(

glad to not need to water soon though, loved the rain we've had so far

Map earlier showed this to be a Central Texas event. Looks to be more like an East Texas event.

Mesoscale Precipitation Discussion 0434
NWS Weather Prediction Center College Park MD
611 PM EDT Sun Jun 16 2019

Areas affected...Central and Southeast Texas

Concerning...Heavy rainfall...Flash flooding possible

Valid 162209Z - 170345Z

Summary...Numerous thunderstorms will continue to affect parts of
central and southeast Texas late this afternoon and into the
evening hours. These are likely to produce heavy rainfall, and in
some cases may concentrate over certain locations for several
hours. Flash flooding is possible in areas where heavy rain can
last for a couple hours.

Discussion...A complex mesoscale environment exists across the
eastern half of Texas this afternoon. In general, though, rain and
thunderstorms have been occurring for much of the day over a large
portion of eastern Texas. This has led to a large area of NE and
EC TX that has been convectively overturned, with RAP analyzed
SBCINH of at least -200 j/kg. Therefore, the trend has been for
convection to gradually focus further west with time. Of
particular note is an outflow boundary that was evident on GOES-16
visible satellite near ACT around 21Z and confirmed by the
observation history with a wind shift and substantial temperature
drop. This outflow boundary is now situated from ACT-TPL-RWV and
new convection was initiating along the boundary. To the north, a
bow echo was pushing to the southeast. A considerable part of the
northern segment of the line should begin to encounter
progressively more stable air, and thus a trend of decay seems
likely. Nevertheless, some of these thunderstorms may begin to
affect areas that have already experienced heavy rain today. The
trailing portion of the bow echo and associated gust front,
oriented NW-SE as of 22Z, seems more likely to link up with the
aforementioned outflow boundary near I-35 and Waco and provide a
focus for more concentrated convection in C TX late this
afternoon. The strongest QPF signal on the 18Z HREF between 21-03Z
is generally in the I-35 corridor from Waco to near Austin and
including portions of Texas Hill Country. Additional thunderstorm
development in an environment characterized by strong instability
and PW around 1.7 to 1.8 inches (GPS observations) should support
rain rates reaching 2 in/hr at times. FFG is relatively high, but
if these rates can be sustained for a couple hours at any one
location, flash flooding will be possible.

A secondary hi-res model QPF signal was concentrated closer to
Houston. A slow-moving cluster of thunderstorms remains situated
from UTS-LFK and the major axis has drifted southeast only approx.
10 miles in the past hour. Additional scattered convection to the
west of Houston continues to lift north and merge into the
convective cluster, leading to a focused area of heavy rainfall
over SE TX. This process may continue into the evening hours given
strong instability in the inflow region and PW values pushing 2
inches (GPS obs). With the strong cold pool to the north, the
storms may not lock into one place for an extended period of time;
rather they should continue to gradually drift south or southeast
consistent with the Corfidi vectors around 5-10 knots from the
NNW. Therefore, the flash flood threat in southeast Texas would be
maximized if inflow bands of convection can become sufficiently
concentrated to lead to localized areas with a heavy rain duration
of at least 90 minutes, or the cluster drifts into more urbanized
areas (e.g. Houston metro area).

Looks like a bust for Houston and southward.
