NWS Forecaster Discussion




Area forecast discussion...updated 
National Weather Service Fort Worth Texas 
517 PM CST Tuesday Jan 27 2015 


Aviation... 


All North Texas terminals will be VFR during this forecast. 


A surface high pressure ridge over the region will move east as 
surface low pressure in the north/Central Plains slides southeast. 
This will result in light southerly winds overnight with speeds of 
14g24kt Wednesday afternoon and around 14kt Wednesday evening. 75 


&& 


Short term.../tonight through Friday/ 
regional surface analysis revealed that some weak cyclogenesis was 
already underway across the central/South Plains this afternoon with 
winds across The Hill Country and western North Texas beginning to 
veer around more to the south. Winds tonight across our area should 
follow suite and become more southerly of around 5 to 8 miles per hour. There 
may be some patchy fog across southeastern zones mainly along the 
U.S. 79 corridor...but thinking is that the models are overly 
aggressive with the low level moisture return. The slight increase 
in the low level moisture and light south winds should help most 
areas stay around 4-7 degrees warmer than last night. 


Surface cyclogenesis across the Front Range should really ramp up on 
Wednesday as the ridge aloft slowly yields to an upper level trough 
that is forecast to swing across the Central Plains on Wednesday. 
The deepening low will help to induce a tight surface pressure 
gradient on Wednesday and thus breezy south to southwest winds of 15 
to 20 miles per hour with gusts up to 25-35 miles per hour can be expected. Warm air 
advection and a slight downslope component to the winds should 
allow temperatures to climb into the upper 70s and low 80s region-wide. 
We may even be within striking distance of a few daytime high 
records...especially out across western portions of the County Warning Area. 
Winds should subside somewhat on Wednesday evening with the loss 
of daytime heating and mechanical mixing. The pressure gradient 
will remain strong enough to help keep overnight temperatures mild into 
Thursday am. 


By Thursday...most model solutions suggest that the 500 mb ridge will 
continue to slide eastward ahead of the next upper level trough. As 
the trough swings east and southeastward...it will drag the 
attendant cold front southward into northwest zones by sunrise on Thursday. 
There appears to be very little in the way of moisture convergence 
along the front and thus have continued with the dry forecast for 
this period. The more noticeable difference will be in the 
wind shift to the north and colder air /at least comparative to the 
past several days/. Breezy north winds...courtesy of surface 
pressure rises across western Oklahoma...should occur across much 
of the County Warning Area with speeds of around 15 to 20 miles per hour. A few gusts to 30 
miles per hour may be possible...primarily across northwest zones. Far southeastern 
zones may still warm up ahead of the front into the upper 60s and 
perhaps even the low 70s with high temperatures in the 50s and 
low 60s elsewhere. 


On Friday...low level NE winds will eventually turn more towards 
the east-southeast in response to an approaching middle/upper low from the 
Baja California of California. The resultant cyclogenesis will help to pull 
moisture northward...especially across western portions of the 
County Warning Area. Have tapered probability of precipitation slightly downward to the slight category 
as the overall evolution of the middle/upper low has slowed somewhat 
from previous runs. That being said...weak isentropic upglide 
along the 290-295k Theta surfaces should result in widespread 
cloudiness across most of the County Warning Area. Temperatures will remain cool 
with daytime highs on Friday in the 40s and 50s. 15-Bain 


&& 


Synopsis... 
another day of unseasonably warm temperatures can be expected 
tomorrow across much of north and central Texas...before a cold 
front slices through the region early on Thursday morning. 
Increasing lift and moisture on Friday through Saturday will 
result in widespread rain chances this weekend. Another 
reinforcing shot of cooler air will occur on Sunday keeping 
temperatures cool into the early part of next week.
