...THE FLASH FLOOD WARNING REMAINS IN EFFECT UNTIL 900 AM CDT FOR
NORTHEASTERN ANDERSON COUNTY...

At 722 AM CDT, Doppler radar indicated that earlier thunderstorms 
producing heavy rainfall had moved east of the area. However, 
additional moderate rainfall will continue over the next hour, and 
observations and radar data indicate between 3 and 4 inches of rain 
has fallen between Palestine and Todd City. This rainfall will 
continue to lead to excessive water runoff and cause flash flooding. 
Low-lying areas are most vulnerable to rapidly rising water. Some 
low-water crossings may flood and become impassable.

Some locations that will experience flooding include...
Frankston, Todd City, Pert, and Neches. 

PRECAUTIONARY/PREPAREDNESS ACTIONS...

Turn around, don't drown when encountering flooded roads. Most flood
deaths occur in vehicles.

BULLETIN - EAS ACTIVATION REQUESTED
Flash Flood Warning
National Weather Service Fort Worth TX
844 AM CDT SAT MAY 20 2017

The National Weather Service in Fort Worth has extended the

* Flash Flood Warning for...
  Northeastern Anderson County in central Texas...

* Until 1000 AM CDT.

* At 834 AM CDT, Doppler radar indicated heavy rain across the 
  warned area. While heavy rainfall has subsided, additional flash 
  flooding may occur in some of the smaller creeks and streams due 
  to residual runoff. Radar estimates that two to three inches of 
  rain have already fallen. This rainfall will lead to excessive 
  water runoff and cause flash flooding, especially across some low- 
  lying areas of far eastern Anderson county near the communities of 
  Frankston and Neches. Some low-water crossings may flood and 
  become impassable.

* Some locations that will experience flooding include...
  Frankston, Neches, and Berryville. 

PRECAUTIONARY/PREPAREDNESS ACTIONS...

Turn around, don't drown when encountering flooded roads. Most flood
deaths occur in vehicles.

When safe to do so, please send any reports of flash flooding to 
local law enforcement. They will relay your report to the National 
Weather Service in Fort Worth.

Area Forecast Discussion
National Weather Service Fort Worth TX
345 AM CDT Sat May 20 2017

.DISCUSSION...
A cold front will continue to move slowly southeast across the
region this morning and exit the forecast area this afternoon. A
broken line of showers and thunderstorms along and ahead of the
cold front will exit the region this morning with only some
lingering post frontal showers and a few storms across the
southeast zones this afternoon. The severe weather potential will
decrease significantly through the day as the upper low lifts
northward across the Central Plains and dry/subsident air filters
in from the north. A few storms could still briefly become severe
across the east/southeast zones, mainly this morning with damaging
winds and marginally severe hail.

Today will be noticeably drier and cooler across all but the
southeast zones. Afternoon highs will range from the middle 70s
across the northwest to the middle 80s in the southeast.

The cold front is progged to remain south of the forecast area
tonight. However, weak isentropic lift will set up and result in
the redevelopment of showers and thunderstorms. Most of the
activity tonight/Sunday morning should remain south of the I-20
corridor, but there is a chance that a few showers and storms
could make it a bit farther north tonight and affect parts of the
Metroplex as per the Texas Tech WRF solution. Any storms that do
develop tonight will be elevated and should be non-severe, but
will have a potential to produce locally heavy rainfall due to
high precipitable water values and slow movement.

Weak isentropic lift will continue Sunday/Sunday night which will
result in scattered showers and storms, mainly across the
southern zones. Precipitation chances will increase on
Monday/Monday night as the front begins to lift northward in
response to another developing low pressure system across the
Central Plains. The warm air advection will be brief due to the
passage of a cold front on Tuesday. The front will be a focus for
showers and storms on Tuesday followed by cooler and drier air
Tuesday night and Wednesday.

The second half of next week will be rain-free with a warming
trend due to building upper level high pressure. It does appear
that rain chances will return sometime next weekend as the upper
ridge builds east and another low pressure system develops in the
west.

.AVIATION...
/ISSUED 1203 AM CDT Sat May 20 2017/
Convection has finally surged eastward in response to a shortwave
trough kicking northeastward across Northwest Texas. This has also
given a cold front a bit of a southeastward push, which should
help fill in the gap in the convection from north of the Metroplex
to the Red River. Since activity is now more progressive, a gusty
wind threat will be the main weather hazard along with frequent
lightning. Storms will push east of the Dallas-Fort Worth area in
the next few hours. Waco may get a bit of a reprieve later
tonight, but then additional rounds of precipitation will be
likely across KACT during the Saturday morning hours as the front
pulls up stationary.
