NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Fort Worth Texas 
1133 PM CDT Tuesday Apr 22 2014 


Aviation... 
light winds continue to veer to a more southeasterly direction 
tonight as a surface ridge works its way east of North Texas. 
Meanwhile an upper ridge remains overhead while an upper trough 
can be seen on satellite moving onto the West Coast. The upper 
trough will move steadily east overnight and 
Wednesday...eventually leading to thunderstorm development 
Wednesday afternoon and evening from the plains southward into 
west-central Texas. Convection will approach the I-35 corridor 
late Wednesday evening...and a few storms may reach the metroplex 
after midnight Wednesday night. Storms may be weakening by then 
due to the presence of a Stout cap...and it is still not certain 
if they will survive long enough to be a major player for Dallas- 
Fort Worth area taf sites. It may just depend on how organized 
convection becomes. For now...will go ahead and include thunderstorms in the vicinity in the 
extended dfw taf after getting a look at both NAM and GFS MOS 
guidance...which indicate a decent chance of storms surviving the 
cap long enough to affect the dfw tracon. Otherwise VFR conditions 
and south winds around 15 knots can be expected Wednesday in advance 
of the system.

Previous discussion... /issued 342 PM CDT Tuesday Apr 22 2014/ 
with middle- and upper-level ridging aloft...it was a pleasant 
afternoon across north and central Texas...with slightly above 
normal temperatures. These ridge axes will soon pass east of the 
area as the storm system now over California swings into the 
intermountain west. As its associated middle-level jet exits the 
high terrain and heads into the Central Plains...Lee troughing 
will be induced at the surface. This will rapidly create a dryline 
through the Panhandle and South Plains on Wednesday...along 
which thunderstorms will likely develop. These storms will have a 
tendency to move east and northeast away from the boundary...but 
the activity will likely be well west of North Texas by nightfall 
Wednesday evening. The convection will be entering an area of 
increasing cin with a stabilizing boundary layer. The main upper 
low will skirt the Canadian border...but a trailing shortwave may 
help maintain at least elevated convection into North Texas 
Wednesday night into Thursday morning. This is not the ideal time 
of day for severe storms...but with a 30- to 40-knots low level jet beneath 
considerable middle-level lapse rates and increasing forcing for 
ascent...there may be some updrafts capable of sustaining large 
hail. Regardless...3rd-period probability of precipitation are low and emphasize lack of 
confidence that the storms will be able to survive into North 
Texas. The GFS/Gem solutions have the trailing shortwave east of 
our area by Thursday afternoon...but the latest NAM/European model (ecmwf) 
solutions are a bit slower. As a result...will maintain some low- 
end probability of precipitation in the far east Thursday afternoon. 


There is still some uncertainty about the storm system that will 
enter the plains this weekend...but there is generally good 
agreement that the compact middle-level low will move north as it 
emerges from the higher terrain to the west. This will result in 
rapid intensification as the feature both stretches vertically and 
moves poleward. The greater uncertainty is related to how much 
energy is available for the Southern Plains. Similar to 
Wednesday...a dryline to our west (but likely closer) may again 
focus afternoon convection that could approach Saturday evening. 
With a vigorous 40- to 50-knots low level jet Saturday night...afternoon 
convection from as far north as Kansas may be able to congeal into 
a nocturnal mesoscale convective system that could find its way into North Texas Sunday 
morning. Another lobe of energy associated with this storm system 
could impact North Texas on Monday. 


The main upper low will then meander toward the Ohio Valley next 
week...and extended guidance is suggesting it could become a cut- 
off. The 12z GFS has reduced the amplitude of both the blocking 
high in the North Atlantic and the longwave ridge across the 
western Continental U.S. (As compared to the 06z solution)...but the cut-off 
remains. Although the European model (ecmwf) has significant differences...it too 
has full-latitude northerly flow through the Central Plains. This 
is not good news for drought-stricken Texas as this will shut-off 
the typical Spring storm mechanisms. CPC 6-10day and 8-14day 
outlooks (encompassing Apr 28 - may 6) show an enhanced likelihood 
of below normal temperatures and below precipitation for north and 
central Texas.
