Area forecast discussion...updated 
National Weather Service Fort Worth Texas 
629 am CDT Friday Oct 24 2014 


Aviation... 
/12z tafs/ 


Concerns...none. 


All airports will see south winds 5-10 kts today...as the region 
remains sandwiched between surface high pressure over the 
Mississippi Valley and weak Lee-side pressure falls to the west. 
A strong upper high over Arizona/nm will continue to expand slowly east 
through Saturday morning. A stripe of moisture located at 800mb 
early today will allow for broken VFR ceilings 5-6kft with scattered 
cirrus arriving in north flow. As the upper high expands...skies 
should become sky clear heading into Saturday. 


05/

Previous discussion... /issued 327 am CDT Friday Oct 24 2014/ 
ridging aloft dominates the southwestern Continental U.S. This morning with 
an upper level trough lingering along the East Coast. The ridge is 
expected to strengthen as it shifts east into the plains over the 
next 36 hours...resulting in increasing temperatures as we head 
into the weekend. Highs in the 80s this afternoon will increase 
to around 90 on Saturday as the ridge axis moves overhead. The 
Saturday record high temperature at dfw is 89 which is certainly 
attainable /the Waco record will be more difficult to reach at 94/. 


An upper trough currently approaching the 140w longitudinal line 
in the Pacific will work its way east into the western U.S. On 
Sunday...which will begin a weakening trend in our upper ridge. 
Lee rockies surface troughing will occur on Sunday in response to 
the approaching upper trough. The resulting surface pressure 
gradient will bring increasing southerly winds across North Texas 
on Sunday and Monday. A cold front will then advance southeastward 
towards North Texas late Monday as the upper trough moves east into 
the plains. Showers and thunderstorms will be possible late 
Tuesday through Wednesday as the front pushes through the region. 
The upper trough will have begun dampening by then while 
simultaneously exhibiting a positive tilt appearance. This 
typically results in less favorable upper level support on the 
synoptic scale for convective development...so we do not expect 
broad coverage of showers and storms. We will maintain the 20 to 
30 probability of precipitation from Tuesday afternoon through Wednesday evening based on 
the latest guidance...with activity occurring mainly near the 
front. 


Models begin to diverge late next week. The GFS indicates another 
upper ridge progressing east into the plains...while the European model (ecmwf) 
keeps the ridge to our west and brings a pretty strong shortwave 
southeast across the Southern Plains and North Texas. If the European model (ecmwf) 
is correct...we would need to include additional probability of precipitation Thursday of 
next week. This would also bring cooler temperatures than 
currently forecast as we head into the end of the week and next 
weekend. At this time...we have trended warmer than the European model (ecmwf) but 
not quite as warm as the GFS in the days 6-7 portion of the 
forecast. We have also left out probability of precipitation for next Thursday-Friday for 
now and would prefer to get some better model consistency before 
trending one way or another on day 7.
