NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Fort Worth Texas 
233 am CDT Tuesday Jun 30 2015 


Discussion... 
we will continue to see a diffluent north flow pattern over the 
Central Plains into early Wednesday...before flat ridging arrives 
later Wednesday into Thursday for a brief reprieve in isolated to 
scattered convection. Currently...an elevated 925mb-850mb front 
extended from near the I-20 corridor up into southeast OK/SW Arkansas this 
morning. A Theta-E axis between 925mb-700mb was expected to be 
situated just off the southeast edge of the elevated front today. 


One little cluster of strong storms from McKinney to Greenville 
continue to be fed by a 25-30 knots south-southwesterly low level jet and will continue to 
migrate south-southwest into the Richer Theta-E airmass through sunrise. 
Current high res models continue to struggle with activity once 
again in the weak diffluent flow aloft and were deemed pretty much 
unusable this morning. Current cluster of storms over our NE counties 
is expected to weaken toward sunrise as current modest low level jet 
weakens. I will still carry 20-30 probability of precipitation generally across the southeast 
half of the County Warning Area today as numerous old outflow boundaries will 
exist with forcing from a subtle shortwave rotating southeast toward the 
northwest Gulf of Mexico. With strong instability and high Theta-E lapse 
rates expected...a few strong to brief severe microbursts and 
very small hail are possible. Locally heavy rainfall and minor 
flooding will be possible due to weak steering currents aloft and 
propagation dominating storm movements. 


For tonight into Wednesday...have lingered slight chances across 
the far southeast counties where the Richer moisture will persist for 
another day. A brief dry period will occur Wednesday night through 
Thursday evening as some enhancement of ridging aloft and 
resultant subsidence occur. However...the eastern Continental U.S. Trough 
will amplify once again by Friday into the Holiday weekend...as 
the upper ridge axis migrates west out of the area once again. 
This longwave pattern change will allow periodic northwest flow shortwave 
disturbances to rotate southeast across the arklatex and bring chances 
for showers and storms across particularly areas north of I-20 and 
east of I-35. It is hard to say how this will affect July 4th 
festivities...but the weather definitely bears watching if you 
plan on being outdoors this Holiday weekend to watch area 
fireworks displays. High temperatures should be slightly below 
normal with temperatures in the lower 90s the end of the week into the 
Holiday weekend. 


A seasonably hot and dry period looks to set up next week...as 
amplification of the longwave pattern dampens with broad ridging 
setting up from the SW states into the central Gulf states. Highs 
in the middle 90s and lows in the 70s are expected with dry 
conditions.

Aviation... 
/issued 1147 PM CDT Monday Jun 29 2015/ 


For the 06z tafs...VFR conditions are expected over the next 
couple of days. Thunderstorm chances are the primary forecast 
concern. 


For tonight...think that all area taf sites will remain 
thunderstorm free...however will continue to closely monitor the 
activity north of the Red River throughout the overnight hours. 
Storms over Marshall and Bryan counties are moving south towards 
an axis of larger potential convective instability according to 
current objective mesoscale analysis. These storms are likely 
elevated in nature...and as a result it is difficult to know if 
these storms will hold together while moving south tonight. The 
lack of deep layer wind shear should favor storms dissipating 
overnight despite the Reservoir of cape in place east of the 
Interstate 35 corridor. As a result...left precipitation out of 
the tafs at this time. 


For tomorrow...forecast soundings once again indicate quite a bit 
of cape/energy for storms with little cap in place across the 
region. While this is generally a favorable environment for 
thunderstorms to develop...we still need some lift to cause 
thunderstorms to initiate tomorrow afternoon. Without an obvious 
lifting mechanism...think that thunderstorm chances are too small 
to include in the tafs for tomorrow afternoon at this time. If a 
lifting mechanism becomes more apparent tomorrow...thunderstorms 
may need to be added to the forecast. 


Assuming storms remain away from area taf sites as forecast...VFR 
conditions and southerly flow can be expected.
