Severe Thunderstorm Warning 242, NWS Fort Worth, TX

Area Forecast Discussion
National Weather Service Fort Worth TX
718 PM CDT SUN MAY 29 2016

.AVIATION...
The primary aviation weather concern Tonight through Monday
morning will be timing convection. Clusters of storms will
continue across the Metroplex TAF sites through sunset. Impacts
will be brief with mainly heavy rainfall, small hail and gusty
winds. Storms should weaken with the loss of surface heating.
However...the storms approaching from the northwest should
organize into a convective complex with a developing low level
jet overnight. These storms should impact the Metroplex TAF sites
between about 05Z and 10Z. Storms should weaken as they move south
and will have less of an impact on Waco overnight/Monday morning
so will just carry VCTS between 07Z and 10Z. The complex of storms
will exit the region before midday Monday.

Some brief MVFR ceilings are likely with and behind the storm
complex overnight/Monday morning, otherwise VFR conditions are
expected Tonight through Monday.

A southeast wind will continue between 6 and 12 knots except for
some strong and gusty winds in and near thunderstorms.

.PREV DISCUSSION... /ISSUED 312 PM CDT SUN MAY 29 2016/
Another week, but the forecast remains the same. Each afternoon,
there will be showers and thunderstorms developing across the
western half of Texas and eventually moving east. Over the next
several days, we will likely see more time without rain than with
rain, but the rain chances will not go away until late in the week
and possibly the weekend. Severe chances this week are lower than
usual for this time of year, with locally heavy rainfall being the
primary threat late Tuesday and Wednesday.

For today and Memorial Day, the forecast should sound familiar.
Thunderstorms are once again ongoing in the Texas panhandle, as
well as just east of the caprock escarpment along a dry line.
These storms will eventually form this evening's mesoscale
complex, and will once again move through much of the area during
the overnight hours. Ahead of the dry line, there is some
destabilization going on with the sunshine and abundant low level
moisture, as dew points remain in the mid 60s. Surface based CAPE
is running from 1000 to 3500 J/kg across North and Central Texas,
which means we could see a few storms develop before 6 PM. Even
so, the chance for rain will increase after 9 PM for most areas.
Memorial Day itself will not be a washout, as the overnight storms
will diminish early in the day, leaving most of Monday with a mix
of sunshine and clouds, before the cycle repeats itself.

Attention then turns to the midweek system, which will likely have
more of an impact on many of us. Low level and mid level moisture
will still be with us by Tuesday night and Wednesday, while upper
level lift will increase as an upper level low moves closer to
North and Central Texas at the same time the next front gets here.
All of this will combine for higher chances for showers and
thunderstorms. Moisture, lift, and instability will be in place,
while the wind shear will not necessarily be favorable for
widespread severe storms. However, the lack of wind shear will
allow for storms to be slow moving and efficient rainfall
producers. If the current forecast holds true, this would produce
a fairly large area of 2 inch rainfall across portions of the
region. This has the potential to cause some flooding issues in
North Texas, mainly from the rate of rainfall, and not necessarily
the storm total amounts of rainfall. As more details are known,
there is the potential for watches being issued. Since the heaviest
rainfall will likely be tied to the exact positions of the surface
and upper air features, confidence is too low at this time to
pinpoint areas for any flood watches.
