NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Fort Worth Texas 
235 am CST Friday Nov 28 2014 


Discussion... 
the upper level pattern across noam will change little over the 
next seven days as a deep wintertime upper level low remains 
intact over northern Hudson Bay. Farther south across our section 
of the country...an upper level ridge over the western U.S. Will 
flatten during the next 48 horus with near zonal flow prevailing 
afterward. Within this zonal flow...a weak short wave trough will 
move across the region late Sunday/early Monday as a cold front 
arrives. This front may produce isolated to scattered light 
showers east of the I-35 corridor on Monday...but any rainfall 
will be light. Have maintained a slight chance of warm advection 
showers on Thursday. 


Today through Saturday...a strong surface pressure gradient will 
result in strong and gusty southerly winds and warming 
temperatures through the period. Some gusts up to 35 miles per hour are 
possible. Currently...do not think a Wind Advisory will be 
needed...but one may be required on Saturday afternoon. With lower 
dewpoints presiding over the northwestern counties on 
Saturday...the wind and above normal temperatures will result in 
an elevated fire weather concern during the afternoon hours. 


Sunday will be a slightly warmer than Saturday...but the southerly 
winds will not be as strong as the pressure gradient relaxes a 
little ahead of a nearing cold front. The cold front should be 
able to enter the northwestern counties shortly after midnight and 
roughly to a Paris to dfw and Goldthwaite line before daybreak 
Monday. 


As the cold front pushes through the rest of the forecast area on 
Monday morning...there will be a slight chance of light showers 
during the day. Otherwise...it will be noticeably cooler Monday 
and Tuesday as a Canadian air mass spreads over North Texas. 
Temperatures will below normal on Tuesday with morning lows in the 
upper 20s over the northwest counties to the middle 40s over the 
southeast. Highs Tuesday will be mostly in the low to middle 50s. 


As the Canadian air mass slides east of the region on 
Wednesday...a return of southerly winds will allow temperatures 
to rebound back to around normal for both Wednesday and Thursday. 


Day 7-10 outlook...another strong cold front is being indicated 
on either Saturday /Dec 6 per GFS/ or late Sunday /Dec 7 per 
European model (ecmwf). Both solutions are producing rainfall along and behind the 
front with the GFS being more aggressive with a widespread 
moderate to heavy rainfall event Saturday through Sunday. 75

Aviation... 
/issued 1140 PM CST Thursday Nov 27 2014/ 
/06z tafs/ 


Concerns...low-level wind shear tonight...gusty winds Friday. 


A surface high has moved into the southeast states. Southerly 
surface winds have returned but are quite light. However...above 
the shallow nocturnal boundary layer...a low level jet of 35kts has ensued 
and will continue throughout the night. With near-calm winds at 
the surface...have introduced low level wind shear into the metroplex tafs. 


These strong winds will mix to the surface by middle-morning Friday. 
GFS/NAM MOS are now generating sustained 20kts by 21z (3 PM cst). 
With deepening Lee troughing...it stands to reason that this 
momentum will sustain itself throughout the day Friday. 


The surface layer will remain well mixed Friday night...with wind 
speeds diminishing very little. The gusty south winds will 
continue to steadily increase low-level moisture. Stratus may 
invade central Texas Saturday morning...but this is currently 
beyond the Waco taf. 25
