NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Fort Worth Texas 
359 am CST Friday Nov 21 2014 


Discussion... 
morning satellite imagery shows extensive low cloud cover has now 
spread across all of North Texas well in advance of a vigorous 
shortwave trough that will bring rain and thunderstorms to the 
region through Saturday. 9z surface analysis indicates a weak 
surface low pressure center southwest of Wichita Falls with a 
stationary frontal boundary extending northeast across south 
central Oklahoma. Middle 50s dewpoints have spread as far north as 
the Red River this morning. A secondary boundary of higher 
moisture exists across south central Texas where dewpoints have 
risen into the low and middle 60s. Water vapor imagery shows a lead 
shortwave trough now moving through the Texas Panhandle. This 
feature will quickly move east of the region by midday. The second 
more powerful system is currently digging into Southern California 
and will arrive in Texas during the day tomorrow. 


Persistent low level warm moist advection continues this morning 
across much of Texas. The axis of strongest lift is expected to be 
across the southeast part of the County Warning Area through midday. This lines up 
well with ongoing showers which currently extend from near 
Victoria through Bryan/College Station and into the Palestine 
area. Scattered showers and possibly some thunderstorms are 
expected to continue for the next several hours across these 
areas. Later today...low level winds will begin to back in 
response to the strong upstream shortwave. This will allow the 
warm moist advection to shift westward through this afternoon. 
While this would typically indicate a westward shift in any 
ongoing precipitation...the departing lead shortwave currently 
over the Panhandle will leave weak subsidence in its wake. All of 
the model guidance indicates weak height rises continuing into 
this evening across most of North Texas. This sets up a battle 
between the weak subsidence aloft and low level forcing for ascent 
spreading westward through this evening. Forecast soundings 
indicate moderate instability developing by this afternoon mainly 
south of I-20 and west of I-35 as steeper lapse rates from West 
Texas advect eastward into the area. While this could potentially 
support some strong to severe thunderstorms this afternoon and 
evening...the lack of significant forcing aloft appears to be the 
main inhibiting factor...especially since significant cloud cover 
is expected to limit heating through the afternoon hours. 


By tonight as the shortwave gets closer...substantial height 
falls will begin to overspread North Texas. There should be a 
shift westward in precipitation along a surface trough axis which 
will likely be across the northwest counties. Showers and 
thunderstorms will increase in coverage through the morning hours 
Saturday as a surface low becomes established and starts to move 
east ahead of the upper trough. Precipitation coverage across 
North Texas will likely be 100 percent during the day Saturday as 
the surface low and best forcing for ascent tracks right across 
the region. Given the proximity to the upper low...wind fields 
will be rather strong with this system...yielding moderate to 
strong deep layer shear values. The main concern regarding severe 
weather potential revolves around the amount of instability that 
actually develops during the day Saturday. Most of the guidance 
continues to suggest that the best instability will remain across 
central and south Texas during the day...with our southern 
counties having the best chance for severe weather. Forecast 
soundings for Saturday afternoon indicate nearly moist adiabatic 
profiles with very little cape suggesting a low threat for severe 
storms. Widespread convection across North Texas will likely be 
well ahead of the cold temperatures aloft associated with upper 
trough. The main concern with this is that it would only take a 
little bit of warming or a little more moisture than advertised by 
the models to substantially increase surface instability in a 
strongly sheared environment. So...confidence remains low 
concerning the severe potential across our County Warning Area. The highest threat 
for severe storms will be south of Interstate 20 through Saturday 
evening. If more robust instability does develop Saturday 
afternoon...there would be a threat for primarily damaging winds 
and even tornadoes given the strong shear. 


Concerning heavy rainfall potential...precipitable water values 
climb in excess of 1.25 inches with this system later tonight and 
approach 1.5 by Saturday which is quite high for this time of 
year. Widespread rainfall amounts of 1 to 3 inches appears likely 
across a good portion of North Texas. The speed at which this 
system moves through and extensive drought conditions across North 
Texas suggest that we will be able to handle that amount of rainfall 
without any significant flooding concerns. Urban flash flooding 
will remain a threat through Saturday. 


All of this activity will move east of the area late Saturday 
night with drier air moving in from the west. Sunday will be nice 
with temperatures warming into the 70s with mainly westerly flow 
in place. The cooler air will arrive on Monday with temperatures 
falling back to upper 50s and lower 60s. The remainder of next 
week should be mostly dry and seasonal.

Aviation... 
/issued 1130 PM CST Thursday Nov 20 2014/ 
..IFR ceilings and a few light showers overnight... 


Stratus has surged north along the Interstate 35 corridor with 
MVFR ceilings becoming common at all metroplex taf sites...and IFR 
ceilings recently arriving at kact. Warm/moist advection will lead to 
a gradual lowering of ceilings through the overnight hours...and IFR 
ceilings will remain in the forecast at all locations prior to 
sunrise. Some light showers are already showing up near kact and 
we should see some of this activity in the metroplex around the 
time the higher moisture and IFR ceilings arrive. Conditions should 
improve to MVFR late Friday morning with light showers 
simultaneously mixing out. Additional showers during the afternoon 
will likely remain east of taf sites where higher moisture levels 
reside. 


Elevated convection will become a possibility in the extended 
time frame /after 06z Saturday/ as strong ascent precedes the 
arrival of the upper low to our west. After a look at the latest 
high res guidance...we will continue to hold off mentioning ts in the 
extended dfw taf...with the latest data pointing at storms 
remaining west of the taf locations through 22/12z. Convection 
will become more likely around 18z or a little later Saturday as 
we destabilize and the strongest lift from the system moves 
overhead.
