Area Forecast Discussion
National Weather Service Fort Worth TX
320 AM CST Mon Feb 20 2017

.DISCUSSION...
A line of thunderstorms continues to progress steadily east across
the eastern-most counties of North and Central Texas early this
morning. The bowing segment over the southeastern counties has a
history of producing damaging winds, and this threat will
eventually shift east of the forecast area as the leading edge
pushes east.

The upper level trough responsible for the convective weather
still remains west of the forecast area. An enhanced area of
ascent appears to be lifting north along the eastern flank of the
upper trough. This is resulting in a second line of storms over
South-Central TX, which may end up affecting areas already hard
hit by damaging winds earlier. Instability has decreased
considerably in the wake of the initial line of storms, so chances
are that these additional storms will remain below severe limits.
Localized flooding associated with the multiple rounds of
convection will be the primary threat across the southeastern
counties through sunrise.

Stratiform precipitation will continue to affect the eastern
third of the region this morning, and may linger into the early
afternoon over the eastern-most row of counties. Rain will shift
east of all counties mid to late afternoon as the upper trough
continues trekking east across the state.

The upper level system is progged to transform into a cut-off low
Tuesday before shifting east-southeast across the northern Gulf.
The resulting shortwave ridging over Texas will keep conditions
warm and dry Tuesday through Thursday, with many areas reaching
the 80s Wednesday and Thursday under sunny skies. A cold front
will push through the area of Friday, cooling things to near-
normal temperatures Friday through the weekend. Rain chances will
return late Sunday into next Monday as a shortwave trough and
another cold front affect the area.
