NWS Forecaster Discussion




Area forecast discussion...updated 
National Weather Service Fort Worth Texas 
1147 PM CDT Tuesday Jul 29 2014 


Aviation... 
although most models try to keep convection north of the 
metroplex...the hi-res solutions do try to move scattered showers 
through the metroplex. Will be keeping vcsh across the metroplex 
during the morning through middle afternoon...then thunderstorms in the vicinity until 
31/02z. Will keep kact dry...but isolated vcsh are possible on 
Wednesday. Otherwise...VFR with light winds tonight becoming 
southeasterly at 9-14 knots on Wednesday. 75 


&& 


Update... 
isentropic lift now occurring between 850-700 mb across northwest 
Texas and western Oklahoma ahead of the expected shortwave embedded 
in weak northwest flow aloft. Lapse rates aloft are not overly 
steep...but some isolated thunder may occur northwest of a 
Breckenridge...Decatur...Sherman line overnight. 


Little rainfall is actually hitting the ground per surface observation 
across western OK/northwest Texas...but earlier rainfall did moisten 
low levels below 700mb earlier today. Even so...have only raised 
to 30-40% with mainly shower wording with an occasional lightning 
strikes across the northwest. Rainfall is expected to be relatively 
light. Did shift slight chances as far southeast as a Cisco...to 
dfw...to Bonham line. Otherwise...no changes.

Previous discussion... /issued 352 PM CDT Tuesday Jul 29 2014/ 
a frontal layer remains intact above North Texas. Elevated 
convection began above this frontal slope before daybreak. The 
activity expanded along an axis of 700mb frontogenesis from 
northwestern Oklahoma...to the Dallas/Fort Worth metroplex...down 
the I-45 corridor to the southeast. Although rain amounts were 
generally light...rain-cooled temperatures were in the 70s during 
the afternoon hours. However...high temperatures on either side of 
this corridor reached the upper 80s...despite cloud cover. This 
axis of precipitation will gradually come to an end by sunset. 
Surface-based thunderstorms have been focused in central Texas... 
where sunshine was plentiful much of the day. Although initiated 
by frontal dynamics...their maintenance is primarily driven by 
surface heating...and this activity will also be gone by middle- 
evening. 


With ridging aloft eroded/displaced to the south...the westerlies 
are now impinging on North Texas. A disturbance embedded in the 
flow over Colorado will approach tonight. As the terrain falls 
beneath it...ongoing Lee troughing will deepen. Southerly winds 
will be induced at the surface across north and central Texas... 
resulting in frontolysis. However...this process will mean 
frontogenesis on the High Plains in the wake of the disturbance 
which will swing through Oklahoma on Wednesday. Still think the 
bulk of the convective activity late tonight and Wednesday will be 
north of the I-20 corridor. 


The main event will be Wednesday night into Thursday as the main 
shortwave now spiraling over Utah is pulled into the plains. The 
flow should result in significant shearing as its remnant energy 
follows the same track as the Wednesday impulse. This too should 
primarily affect northern and northeastern zones...but its passage 
should allow the new front on the High Plains to surge through the 
region. This will give southern and eastern zones a chance for 
some precipitation late Thursday before the unseasonal rainy 
period comes to an end. 


Sunshine will return Friday...but cold advection will keep 
temperatures below seasonal normals. In fact...persistent 
northerly flow will mean a very slow warming trend. The mild air 
will gradually moderate...but temperatures will remain below 
normal into next week when the Gulf finally reopens.
