NWS Forecaster Discussion




Area forecast discussion...updated 
National Weather Service Fort Worth Texas 
643 am CDT Thursday Aug 21 2014 


Aviation... 
/12z tafs/ 


Mainly VFR with breezy south winds through Friday morning. Brief 
rounds of MVFR ceilings will pose challenges each morning between 
sunrise and middle morning...mainly at Waco. Strong 30-35 knots low level jet for 
this time of the year is expected to veer more Friday morning in 
response to northern rockies upper trough having moved further 
east. For this morning only...MVFR ceilings 2.5 kft will be patchy 
enough that a tempo group at eastern dfw airports will likely 
suffice. Mixing should occur quickly each day and do not expect 
MVFR ceilings to last more than 2-3 hours. 


The aforementioned low level jet should mix easily down by late morning with 
south winds around 15 kts with occasional gusts 20-25 kts. Pressure 
falls to the west will also keep winds up...even into tonight with 
a tight surface pressure gradient present. 


05/ 


&& 




Previous discussion... /issued 542 am CDT Thursday Aug 21 2014/ 
remarkably Stout low level jet for this time of year (35-40kts) has 
resulted in widespread (albeit thin) stratus along the Balcones 
Escarpment. A fibrous deck has invaded southern portions of the 
County Warning Area early this morning...and a few fragments will likely reach the 
I-20 corridor after daybreak. As these strong winds mix with the 
surface layer later this morning...wind gusts will pick up again. 
Sunny skies will push temperatures back up into the upper 90s to 
near 100 degrees...but the wind will help take an edge off the 
heat. With the best moisture flux into Louisiana today...expect 
the western extent of the sea breeze activity this afternoon will 
be in far southeast Texas. 


The troughing in the western states is prognosticated to be a bit weaker 
with the main upper low taking a sharp left turn into the prairie 
provinces late in the weekend. As a result...the middle-level ridge 
in the southeast will be able to build farther west the previously 
prognosticated. The ridge will be neatly stacked vertically above the 
boundary layer...from 10kft above mean sea level to around 35kft...which will 
assure subsidence will dominate into next week. However...its 
intensity is still rather Ordinary for August...and its placement 
east of Texas should prevent temperatures from soaring into the 
triple digits. In addition...breezy conditions will continue the 
remainder of the week...which will prevent optimal heating of the 
surface layer. This will reduce high temperatures 1-2 degrees from 
what would otherwise be expected...meaning that achieving triple- 
digit highs will be a little more difficult. A nightly low level jet will 
mean repeated stratus intrusions...primarily into central Texas. 
These morning clouds will be short-lived and will do little to 
prevent hot afternoons. Heat index values will easily top 100 but 
should remain below 105. 


A piece of upper vorticity is still prognosticated to eject from the 
TUTT south of Brownsville...and the southerly flow beneath it will 
guide it northward over the Lone Star state. The polar jet will 
effectively shear it...but the troughiness in the upper reaches 
of the troposphere will linger through the weekend. Even so...the 
feature will quickly become an open wave and should be unable to 
disrupt the deep subsidence beneath it. 


As the upper low enters Canada...the flow aloft into the Central 
Plains will diminish considerably. A corresponding weakening of 
the persistent Lee trough will mean lighter surface winds across 
north and central Texas. This will bring an end to the morning 
stratus and will make the heat feel a little more oppressive... 
but it may also allow the sea breeze to reawaken. 


The GFS and European model (ecmwf) solutions diverge next week...with the European model (ecmwf) 
developing a cut-off low and the GFS far more progressive. The 
Canadian is a compromise between the two...but leans toward the 
GFS in that it keeps the flow unimpeded. Despite considerable 
spread among the GFS ensemble members...the consensus favors a 
frontal passage late next week. Have introduced north winds and 
slight precipitation chances on Thursday next week...but these will not 
appear in the public forecast until the afternoon package today. 


25 


&& 


Fire weather... 
hot and rain-free conditions will persist through the weekend. A 
broad upper high will be centered across the western Gulf states 
and will result in highs between the middle 90s and 102 degrees 
across the area. Hottest high temperatures will be across the 
far western counties where deeper mixing will result in lower 
afternoon humidity values each day between 20 and 30 percent. 
However...20 foot winds will remain sustained between 10 to 15 miles per hour 
with occasional gusts exceeding 20 miles per hour. A weak surface low near 
the western half of North Texas should keep winds from becoming 
too strong. This area will need to be watched closely in the 
coming days for a high fire danger...particularly those areas 
northwest of a Gainesville...Decatur...Comanche line. Fuel moisture 
levels at both possum kingdom Reservoir and Miller/S creek RAWS 
observations were already below 10...indicating some drying of 
fine fuels across the area. 


Otherwise...areas further to the east may see occasional higher 
gusts but will also see Richer Gulf moisture and afternoon 
humidity values remaining above critical levels. The higher 
humidity across the eastern areas should hold high temperatures 
into middle to upper 90s. The fire danger should remain low into early 
next week...as wind speeds remain below 15 miles per hour.

Climate... 
late August frontal passages are remarkably common. Although normal 
high temperatures (based on dfw data 1981-2010) gradually decrease 
after August 17 at a steady rate...the average temperatures tell a 
different story. 


Daily normals are created using a harmonic fit...a method employed 
to dampen outliers. The result assures a smooth transition from one 
day to the next...but this smoothing removes intricacies in the data 
that can reveal more abrupt seasonal transitions. For example...much 
of the decrease in high temperatures during late August occurs in a 
2-day span between August 26 and 28. 


The data below are based on the Dallas/Fort Worth climate record 
1981-2010. 


Average normal 
high / low high / low 


August 26 97.4 / 75.4 95 / 74 
August 28 93.5 / 73.4 94 / 74 


The average high temperature (1981-2010) actually increases between 
August 17 and 26. The sudden 3.9-degree drop in just 2 days (august 
26-28) is thus very significant. 


These are not simply artifacts of a 30-year data set. Using the 
entire climate record (which began in September 1898) yields a 
decrease in the average high temperature between August 17 and 26 
(1.2 degrees) that is still less than the 2-day span August 26-28 
(1.4 degrees). And yes...when incorporating the entire climate 
record of more than a century of data...the time frame of the 
significant drop remains August 26-28. 


What does this mean? 


It means that historical frontal passages cluster around these 
dates...showing a tendency for the first significant late Summer 
front to occur at this time. It looks like 2014 may follow suit. The 
GFS projects a frontal passage next week on August 28. 


Does this mean fall has arrived? 


Not quite yet...as high temperatures will likely be in the 90s even 
if the cold front arrives. Normal (and average) high temperatures 
are still in the 90s in early September. 


Another significant drop in average temperatures occurs around the 
autumnal equinox...which is only a month away. (The below are based 
on dfw data 1981-2010.) 


Average normal 
high / low high / low 


September 20 88.1 / 65.8 87 / 66 
September 24 83.1 / 62.6 85 / 64 


Perhaps there is something to the first day of fall.
