you will do if flash flooding develops. Stay informed and be
ready to act if you see flooding or if a Flash Flood Warning is
issued.

NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Austin/San Antonio Texas 
322 PM CDT sun may 24 2015 


Short term (tonight through Monday night)... 
the short break from precipitation continues late this afternoon 
into the overnight hours. A few showers and an isolated 
thunderstorms are still possible later this afternoon. Have seen a 
few isolated showers beginning to form up in Williamson County. 
This supports what the hrrr shows through the evening hours. 


Dry air has filtered in behind the two lines of convection this 
morning. All of the models have south central Texas remaining dry 
overnight with only the NAM showing any convection/quantitative precipitation forecast overnight. 
Will discount the NAM for now. 


The next upper level disturbance is now along the 
California/Arizona border. This will approach the area Monday. 
Models are a bit split on timing of the showers and thunderstorms 
tomorrow...but they are in fairly good agreement on quantitative precipitation forecast amounts. 
The NAM...GFS...and European model (ecmwf) all concentrate quantitative precipitation forecast across the northern 
I-35 corridor and points east with lesser amounts across The Hill 
Country and Bexar County area. Still though models are showing 1 
to 3 inches across areas that not only had 1 to 3...or in some 
cases a lot more...inches of a rain last night but have also had 
several heavy rain events over the last few weeks...like the 
Bastrop and Lee County areas. The heavier storms tomorrow could 
produce locally heavy rainfall up to 5 inches. This should be 
enough to cause more flooding concerns so for that reason we will 
be issuing a Flash Flood Watch from 10 am Monday through 1 am on 
Tuesday. Again although quantitative precipitation forecast amounts are expected to be lower 
tomorrow than they were last night the already saturated ground 
cannot take anymore rainfall leading to the enhanced flash flood 
risk. The line of storms will be fast moving so precipitation 
should be ending by late Monday night. 


Most of the mesoscale models begin convection across the Edwards 
Plateau as early as 7 to 10 am tomorrow. Early on storms should be 
more cellular. Eventually these storms will form into a line of 
showers and thunderstorms much like what we saw come through last 
night. This line would approach the I-35 corridor middle to late 
afternoon tomorrow. Severe weather parameters are again impressive 
for tomorrow with forecast soundings showing plenty of instability 
and shear to support not only the threat for large hail and 
damaging winds...but also a few isolated tornadoes. Similar to 
yesterday afternoon and overnight the storm Mode that the storms 
take will most likely determine the main threats. The longer the 
storms stay cellular the better the chances for tornadoes. With 
most models showing a linear system coming across the I-35 
corridor the main threats will be straightline winds...some 
isolated hail...and the possibility of a qlcs tornado or two. We 
saw several circulations or spin ups along the line of 
thunderstorms last night as it progressed across the area. A storm 
survey team is current en Route to go determine if there were any 
tornadoes or if the damage was caused by staightline winds. Models 
have the line of storms through the area by 10 PM to midnight 
Monday into early Tuesday morning. 


In summary...quiet night tonight...convection starting early 
tomorrow...Flash Flood Watch starting at 10 am...convection 
approaching the I-35 corridor middle to late afternoon with a threat 
for locally heavy rain and severe weather...moving out of the 
area late Monday night into Tuesday.

Long term (tuesday through sunday)... 
middle week should see a lull in precipitation for Tuesday through 
Thursday morning as the upper level pattern becomes more zonal and 
even some weak ridging takes place across south Texas. While the 
pattern becomes more progressive another trough drops across the 
western U.S. With another disturbance tracking across the 
southwest U.S. By late Thursday into Friday. This will up 
rain chances again into the weekend as the trough also drags a 
boundary across the area. The wet and rainy pattern looks to 
continue. Another factor that may play into the weather late next 
week is that models are forming a tropical system in the Pacific 
that could send moisture up our direction.
