NWS Forecaster Discussion




Area forecast discussion...updated 
National Weather Service Fort Worth Texas 
629 am CDT Tuesday Apr 21 2015 


Update... 
mother nature continues to throw the proverbial curveball early 
this morning as forcing a little stronger than anticipated and middle 
level lapse rates steep enough that anywhere east of a Graham...to 
Meridian...to Bell County line could see some isolated high-based 
thunder. Will update to reflect these changes but still do not 
expect rainfall to be anything to write home about as cloud bases 
remain 7-8 kft or higher. Activity will move east 25-30 miles per hour. 


05/

Aviation... 




For the 06z tafs...no significant changes were made from the 00z 
tafs...so the previous forecast discussion was appended below. 


The chances for elevated convection building over the dfw area 
tomorrow morning are looking better...so expect scattered 
showers...and possibly some thunderstorms mixed in building over 
the area by 15z Tuesday morning. Did not want to go with 7 hours 
of thunder in the tafs for now...so left vcsh in and will refine 
to add thunder in a smaller time increment by early tomorrow 
morning. 


Cavanaugh 


../previous aviation discussion/... 
/issued 720 PM CDT Monday Apr 20 2015/ 


For the 00z tafs...elevated rain showers or thunderstorms on 
Tuesday are the primary forecast concern. 


A relatively dry low-level air mass in place across the region 
will keep conditions VFR through tomorrow morning. VFR conditions 
are likely to hold throughout the day on Tuesday as well...however 
elevated moisture return may result in some scattered showers or 
thunderstorms developing across the region after 15z tomorrow. 
Models are not consistent with the onset or placement of this 
elevated convection tomorrow...however most models show some 
elevated precipitation develop by the late morning hours of the 
day. 


Forecast soundings indicate some shallow cape for air lifted from 
the 850 mb level or about 1 mile above ground level. Confidence in scattered 
precipitation developing on top of the dfw area is not high at 
this time...so chose to highlight the most likely period for 
precipitation with a mention of vcsh from 15 to 22z. May have to 
add a mention of thunderstorms in the vicinity or just a couple of hours of persistent 
thunder if confidence increases that this elevated convection will 
develop right on top of the dfw area. 


Aside from the potential for elevated showers and storms near 
airports tomorrow...VFR conditions and southerly flow is expected 
to persist throughout the day. 


Cavanaugh 




&& 


Update... 
a weaker shortwave disturbance embedded within fast zonal flow 
over The Hill Country has combined with steep middle level lapse 
rates for isolated...high-based activity between Gatesville and 
Waco early this morning. Same for near Palestine. Will only 
advertise isolated showers for the morning hours across the 
central Texas counties. Update mainly for matrix products is 
expected due to the low impact of these showers. We will also 
carry short term forecasts covering any of the southern...isolated 
shower activity. 


05/

Previous discussion... /issued 413 am CDT Tuesday Apr 21 2015/ 
an active Spring split-flow pattern is expected across the 
central U.S and plains states into the Mississippi Valley the 
latter half of the week. Currently...at the surface cool high 
pressure continues to ease slowly east of North Texas. Light 
southeast winds are returning...though the low level airmass 
remains dry with much of the area in the 50s. A shortwave was 
moving rapidly east over western Oklahoma with scattered light 
showers and an occasional embedded elevated thunderstorm across 
that area. This shortwave will progress readily eastward over 
Arkansas and the arklatex region later this morning. Have 
included low to slight chance probability of precipitation for mainly areas east of I-35 and 
north of I-20 for the morning hours...with slight chances lingering 
across the eastern counties this afternoon. I expect minimal 
rainfall with this system due to the aforementioned dry low 
levels. Confidence regarding lingering lift this afternoon and low 
rain chances is also very low...considering the lack of any 
surface boundary in the area. Otherwise...a partly sunny day will 
be in store with most areas seeing highs warm to between 75 and 80 
degrees. 


Low level moisture return will begin in earnest tonight into 
Wednesday...as broad week upper low near San Diego drifts 
gradually east and a nocturnal 30-40kt low level jet develops overnight. 
Isolated thunderstorms may form off the West Texas dryline and 
move east toward our far western counties by middle evening...but 
again confidence is low on activity sustaining as it traverses 
into a more stable and capped airmass over our area. Morning 
stratus should return northward tonight as well as a shortwave 
ejects northeast over nm and far West Texas later Wednesday morning 
and deepens the dryline and surface low across that area. To the 
north...a surface warm front will stall across central Oklahoma 
during the afternoon hours with the dryline mixing eastward towards 
our far western counties. 


The shortwave trough will likely dampen the shortwave ridge aloft 
over the Southern Plains around time of peak heating. Widely 
scattered thunderstorms should fire by middle afternoon off the 
dryline...while more numerous thunderstorms are expected to 
develop along the boundary across central/southern OK during the 
afternoon hours. With North Texas in the warm sector and with 
highs forecast to climb towards 75 to 85 degrees...destabilization 
will occur both at the surface and aloft with cooling middle level 
temperatures. The set up will be there for a severe weather 
outbreak with discrete supercells along the dryline moving into our 
far western counties and along the warm front across central and 
southern OK through early evening. As we move into the overnight 
period Wednesday night/early Thursday morning...we look for activity 
to morph into a severe mesoscale convective system or storm cluster that will move southeast 
across mainly the northeast third or more of the County Warning Area. Discrete 
activity across the west and southwest counties will likely weaken 
or dissipate...as the strengthening nocturnal low level jet enhances the 
capping inversion over these areas Wednesday night. Severe weather 
hazards with any discrete activity early in the event and across 
mainly our western counties and along the Red River will be very 
large hail...damaging winds...frequent lightning and possibly a 
tornado or two....transitioning to more of a damaging wind and 
heavier rain threat across our northeast counties Wednesday night 
with frequent lightning. 


A residual outflow boundary most likely will be draped somewhere 
near the I-20/1-30 corridors or just northeast dfw metroplex 
Thursday morning with best storm chances occurring northeast of the 
boundary. Some weakening of the mesoscale convective system across the northeast counties 
will occur by daybreak Thursday and after...as the low level jet weakens and 
veers and the boundary layer stabilizes. By Thursday afternoon...the 
southwest U.S upper low will move east over the Arizona/nm border area 
with another shortwave disturbance ejecting out of this feature and 
over the top of a flat shortwave ridge over North Texas. The 
combination of large-scale ascent...heating...and initiation along 
the dryline over The Hill Country and the residual outflow boundary 
in the vicinity of I-20 should result in the initiation of scattered 
strong to severe storms across much of the area once again Thursday 
afternoon and evening. Strong effective 0-6 km bulk shear to 50 kts 
and instability will be present to sustain activity even through the 
overnight hours into early Friday morning. Wednesday and Thursday 
will likely be our biggest severe weather threat days and all 
parties should prepare accordingly. 


On Friday...the upper trough lifts quickly northeast across the 
Central High plains with a surface low forming over southeast Colorado 
Friday morning...moving east across the Kansas/OK border through the 
day and into the Ozarks Friday night. This will pull a dryline 
through the area during the afternoon and early evening hours with 
still a potential threat for strong to severe storms across mainly 
areas east of I-35...before a Pacific cold front moves through during 
overnight and ends our rain chances for the weekend. I did adjust 
for these trends...as most model MOS guidance seemed too wet for the 
Friday night and Saturday morning period. 


The weekend should be mild and pleasant as a ridge of high 
pressure both at the surface and aloft maintain over the area. 
Left low thunderstorm chances in for north and east areas Sunday 
night and next Monday...as a shortwave breaks down the upper ridge 
and transverse across southern Oklahoma. Surface dew points should 
be mainly in the 50s during this time frame...though some lower 60 
dew points may ease back north across the southeast counties. At 
this time...it does not appear any of this activity would be severe 
considering the lower level airmass will still be recovering. We/ll 
re-asses the early next week potential as we get past the active 
period we/re expecting the latter half of this week.
