NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Fort Worth Texas 
1236 PM CDT Tuesday Mar 31 2015 


Aviation... 
VFR with south flow near 15kt will prevail through the evening. 
Main region of convective activity is expected to occur near the 
Red River valley later this afternoon and evening...with general 
motion of storm clusters east-southeast. This activity should stay 
just north of metroplex taf sites and will leave thunderstorms in the vicinity out of 
tafs. Any convection that fires west of the metroplex should be 
fairly isolated and likely dissipate before making the journey far 
enough east into the metroplex. 


Otherwise MVFR ceilings are expected to return tonight but rap 
forecasts show a more southwesterly low level flow than the other 
models. This would keep bulk of stratus east of metroplex taf 
sites. Will side more with the other guidance...but given the SW 
flow above the surface and the dry air in this layer...will show a 
smaller window of MVFR for ftw/afw late tonight and into the 
morning with act/Dal seeing several more hours of MVFR conditions. 


Cap looks weak enough tomorrow afternoon for scattered convection 
in the vicinity of dfw for the extended taf.

Previous discussion... /issued 353 am CDT Tuesday Mar 31 2015/ 


00z upper air analysis showed a plume of steep middle-level lapse 
rates in place over much of the Southern Plains...likely 
associated with an elevated mixed layer (eml). Aside from steep 
middle-level lapse rates...this eml also represents a fairly Stout 
capping inversion in place over the region with regards to surface 
based convective potential instability. Early morning surface 
analysis showed that there was at least some modest moisture in 
place below this eml cap...with dew points in middle 60s along the 
Gulf Coast to the lower 60s across most of north and central 
Texas. Water vapor satellite imagery showed a compact upper level 
low pressure system over the Baja California peninsula...with upper level 
ridging located due north of this feature...over the northern 
Continental U.S. And Canadian rockies. Upper level troughing was located over 
the northeastern Continental U.S. And just off the coast of the Pacific 
northwest. This left the Southern Plains in weak west to northwest 
flow aloft early this morning. 


Today...with a Stout cap in place...expect that wherever early 
morning stratus winds up...it will be slow to mix out this 
morning. Expect clouds to eventually scatter out this 
afternoon...leaving partly cloudy skies in place for most 
locations. The cap should also ensure a dry forecast for most of 
the County Warning Area today...with attention focusing just west of the County Warning Area as a 
dryline organizes from Wichita Falls to near Abilene around 21z. 
31/00z model guidance consistently advertises convection 
initiation along the dryline at or around 00z/7pm this evening. 
The flow aloft is generally out of the west-northwest as mentioned 
above...so any convection that initiates along the dryline should 
tend to move east into better low-level moisture...but also into 
stronger capping associated with the eml. High resolution 
convection allowing models also indicate convection initiation 
along the dryline...but generally favor storms developing near 
Abilene rather than near Wichita Falls which is what 
global/coarser resolution models favor. Either way...there 
appears to be a decent chance for isolated thunderstorms to 
develop along the dryline west of the County Warning Area by late this 
afternoon...moving east across western portions of the County Warning Area this 
evening. 


If storms are able to develop along the dryline...they will likely 
be strong to severe with models advertising 1500 to 2000 j/kg of 
surface based cape just east of the dryline late this afternoon. 
The flow aloft is not overly strong however...and deep layer shear 
is expected to be on the order of 25 to 30 kts...which is marginal 
for a supercellular storm Mode. With the deep layer shear vector 
and flow aloft oriented perpendicular to the dryline...the 
initial storm Mode would likely be discrete...possibly growing 
upscale into a multi-cell cluster or line a couple of hours after 
initiation. Think that the lack of stronger upper level forcing 
will limit the coverage of storms...so only went with a 20 pop 
west of Interstate 35 this afternoon...and a 30 pop after sunset 
taking into account the potential for upscale growth. It is 
entirely possible that there will not be enough forcing along the 
dryline to get convection initiated in the warm/moist sector to 
the east...so also kept probability of precipitation low to account for uncertainty 
regarding storms being able to develop and move into the County Warning Area. If 
organized storms move into the County Warning Area...anticipate that large hail 
and locally damaging wind gusts will be the primary hazards. Low- 
level shear is expected to remain somewhat weak...so unless a 
strong discrete supercell develops...think that the overall 
tornado threat will be low this afternoon and this evening. 


Wednesday...the Baja California upper trough/low is expected to move east off 
the Mexican high terrain and over central Texas tomorrow 
afternoon. Model guidance has been trending weaker and weaker with 
this system as it moves over Texas on Wednesday...so overall 
confidence in sufficient lift to support widespread rain showers 
and thunderstorms over the region has diminished. The best forcing 
for ascent associated with this upper trough is expected to move 
over the far southeaster County Warning Area Wednesday afternoon. Went ahead and 
kept probability of precipitation in the 30 to 40 percent range east of I-35 and south of 
I-20 as a result...but dropped probability of precipitation into the 20 to 30 percent 
range elsewhere. Overall the additional upper level cloud cover 
out ahead of this system appears to diminish the potential for 
strong surface heating...so chances are that the eml cap will 
simply prevent thunderstorms for developing across most of the 
County Warning Area. May see some elevated rain showers accompany the plume of 
middle-upper level moisture associated with the upper trough...but 
do not think any organized thunderstorm activity is likely near 
the upper trough. The focus for thunderstorm activity on Wednesday 
will likely be well north of the County Warning Area...centered over the Central 
Plains where a cold front and stronger upper level forcing are 
expected. 


Thursday...for the most part on Thursday...upper level flow will 
remain westerly with no obvious shortwave troughs upstream to 
provide lift. This generally favors dry conditions across the 
County Warning Area...and that may pan out. However...the cold front that moves 
south through the Central Plains is expected to move across 
Oklahoma Thursday...approaching the Red River by 00z/7pm Thursday 
evening. To the south of this front...model guidance consistently 
shows that a strong dryline will move east towards the Interstate 
35 corridor. With persistent southerly flow from the preceding 48 
hours...low-level moisture will be in place...albeit trapped under 
a fairly strong inversion near the 825 mb level. This inversion is 
the base of another eml that models indicate will advect over the 
region Thursday afternoon. The combination of steep middle-level 
lapse rates and low-level moisture has models advertising anywhere 
from 2-3000 j/kg of surface based cape near the Interstate 35 
corridor Thursday afternoon. The flow aloft is also expected to be 
strong on Thursday...0-6 km bulk shear vectors forecast to be 
anywhere from 40 to 50 kts out of the west...oriented 
perpendicular to the dryline. While this combination of parameters 
is highly favorable for supercell thunderstorms...the main 
forecast challenge is determining whether storms are even possible 
given the lack of upper level lift/support. 


Convection allowing guidance does not extend out far enough to 
resolve convection initiation chances along the dryline at this 
time. Standard model/convection parameterized guidance all show 
the dryline near the Interstate 35 corridor...and all fail to 
generate precipitation Thursday afternoon/evening along the 
dryline. While this seems like a fairly clear cut message...the 
cap will be too strong for storms...these models are also 
advertising a quick increase in middle-level relative humidity along 
the dryline Thursday afternoon. This is likely due to persistent 
lift...and possibly the models activating their shallow convection 
schemes ahead of the dryline. Thought that the potential for 
mesoscale lift along the dryline was sufficient to advertise at 
least a small chance of thunderstorms along the Interstate 35 
corridor Thursday afternoon and evening. If the cap is too 
strong...we will likely just see some simple convection 
attempts/orphaned anvil clouds along the dryline Thursday 
afternoon. However wanted to at least advertise the chance for 
storms along the dryline because if anything develops...it is very 
likely to become severe quickly and be capable of producing very 
large hail and damaging wind gusts. Will continue to keep a close 
eye on thursday's dryline. Regardless of what happens with 
thunderstorms on Thursday...critical fire weather conditions are 
possible west of the dryline. These conditions are discussed in 
more detail in the fire weather forecast. 


This weekend...the Central Plains cold front is expected to move 
south across the County Warning Area Thursday night into Friday morning. Because 
this is the most stable time of day...chances are that the front 
will move across the County Warning Area without any thunderstorm activity. If the 
front were to speed up and meet the dryline Thursday evening...the 
triple Point of dryline/cold front/warm sector would be a very 
favorable initiation point for thunderstorm activity. At this time 
it looks like the front will remain in Oklahoma until late 
Thursday night/early Friday morning...after the near surface 
environment is too stable for thunderstorm initiation. 


Temperatures are expected to be much cooler behind the 
front...with highs topping out in the middle to upper 60s Saturday 
and Sunday across North Texas. Precipitation chances increase 
quite a bit on Sunday as Gulf moisture surges north over the 
front. Expect mostly rain shower activity with some embedded 
thunderstorms as lapse rates aloft are expected to be near moist 
adiabatic...or just barely unstable enough to support convective 
updrafts. 


Early next week...a warm front will move north across the region 
Sunday evening...bringing US back into the warm sector by Monday 
afternoon. We are expected to have steeper middle-level lapse rates 
again with good quality low-level moisture in place. This general 
combination yields a conditional thunderstorm threat across the 
County Warning Area during the peak heating hours of the day for Monday through 
Wednesday. It is too early to determine the likelihood of any 
severe thunderstorm chances...however if there is sufficient lift 
early next week...there will likely be an attendant risk of some 
strong/organized thunderstorm activity. Temperatures will likely 
be at or above normal Monday through Wednesday.
