NWS Forecaster Discussion




Area forecast discussion...updated 
National Weather Service Fort Worth Texas 
1121 am CST Friday Nov 28 2014 


Aviation... 
/18z tafs/ 


VFR conditions expected across most of North Texas through the 
period although some low clouds may try to make a run at the 
airports during the morning hours on Saturday. Currently a tight 
pressure gradient across the region will result in gusty south 
southwest winds which will continue into Saturday. Some low level 
moisture will surge northward tonight although very strong 
southwest winds just above the surface should help keep most of 
the associated low clouds along and east of Interstate 35 early 
Saturday morning. For now will just include a sct012 at the major 
airports for Saturday morning...although MVFR ceilings are expected 
east of there. Otherwise...south winds will continue through 
Saturday afternoon with VFR skies.

Previous discussion... /issued 235 am CST Friday Nov 28 2014/ 
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
