NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Fort Worth Texas 
658 PM CDT Sat Apr 18 2015 


Aviation... 
broken convective line from Gainesville to Lampasas moving 
eastward...and will impact the dfw-area terminals and Waco in the 
01z-03z timeframe. Wind gusts in excess of 40kts...isolated 60+kts 
as activity works across the metroplex and Waco. Most thunderstorms and rain should 
be clear of all taf sites by 04z. Residual -shra expected until 
approximately 05z. May see some MVFR ceilings/visibilities intermittently at 
all sites through 12z...but shouldn't last long enough to include 
in tafs at present. Expect VFR conditions area-wide after 12z 
Sunday. 


Winds at metroplex taf sites will veer through the morning 
hours...then shift to a west/northwest direction in the 19-21z 
timeframe as a front sweeps through the area. Winds will likely 
gust at times to 20-25kts...presenting some possible crosswind 
issues Sunday afternoon. Frontal passage and associated wind shift 
at Waco will occur in roughly the same time window 19-21z as well.

Previous discussion... /issued 255 PM CDT Sat Apr 18 2015/ 
the upper level level low that has spent the last couple of days 
over the central rockies is now on the move eastward out into the 
plains. A shortwave trough axis rotating around the base of the 
upper low will track through North Texas this evening and provide 
the lift required to generate convection. Already showers and 
storms are forming across west central Texas...along an organizing 
dry line. The approaching shortwave trough and partly sunny skies 
has allowed the airmass over the region to begin the recovery 
process from the convective overturning/stabilization that 
occurred last night. Objective analysis has convective inhibition 
eroding over most of the region...but about 50 j/kg of surface 
based cinh remain. A few more hours of heating and increasing 
southerly winds will continue to help prime the atmosphere for the 
scattered storms as they move in from the west late this afternoon. 


Surface based cape will range from 1000-2000 j/kg...which is 
enough for a large hail threat especially given the steep middle 
level lapse rates and relatively low -20c and 0c heights. Bulk 
wind shear is not too impressive but is adequate for some 
transient supercell structures. We generally expect the storm 
activity to evolve into multi-cell clusters or short line segments 
with an eastward motion by early evening. Damaging winds will be 
possible...especially where these line segments organize. Not 
everyone will be directly impacted by the heavy rainfall or storms 
this evening...but we have increased probability of precipitation into the likely category 
since most locations will probably see rainfall. A Severe 
Thunderstorm Watch is in effect west of the I-35 corridor...where 
the severe risk is greatest. However conditions across the I-35 
corridor do look a little more favorable for severe weather than 
yesterday so it is possible the box will be expanded eastward or a 
new one will be issued in a few hours. As for timing...storms will 
affect the western zones now through 8pm...the I-35 corridor from 
7 to 11 PM...and the eastern zones from 9 PM to 2 am. Probability of precipitation will 
end from west to east tonight as the shortwave trough moves east. 


A surface low will track along the Red River valley Sunday and 
send a cold front through the region during the daytime hours. 
Winds will become southwesterly by morning...gradually veering to 
the west and northwest during the day. Winds will be a bit breezy 
from the northwest by late afternoon as deep mixing of the lower 
atmosphere transfers higher momentum air down to the surface. 
Some gusts to 30 miles per hour are possible by late afternoon. With the 
veering winds and mainly sunny skies tomorrow...temperatures will 
benefit from downslope subsidence and warm into the 80s areawide. 
Across the eastern zones...the airmass will become very unstable 
and weakly capped ahead of the front during the afternoon hours. 
However convection will have trouble developing due to the drying 
effects of westerly winds above the surface. Still we will hold 
onto low probability of precipitation for isolated convection. Some severe threat does 
exist...but it is likely the cells that do form in our County Warning Area will 
have moved into East Texas before growing mature enough for 
severe weather. 


Much cooler weather is expected Sunday night with temperatures falling 
into the middle 40s and middle 50s for lows. Another piece of upper 
level energy will move through the northern zones early Monday 
morning causing lift and saturation aloft. This will surely result 
in middle level clouds and virga...and perhaps some light showers or 
sprinkles if the low levels are moist enough. Will keep the 
forecast dry for now but it is something to watch. These clouds 
should dissipate by midday Monday with mostly sunny skies and 
pleasant conditions. Highs will only be in the low 70s with 
another cool night Monday night. Southerly winds return on 
Tuesday...but moisture will be slow to arrive and model guidance 
has backed off on quantitative precipitation forecast so will show a dry forecast. 


Model guidance continues to display a lot of disagreement in the 
middle to late week as they are struggling with the subtle features 
in the west/southwest flow aloft. There is agreement that the cap 
will be pretty tough to overcome Wednesday and Thursday and 
therefore will keep probability of precipitation in the slight chance category. By 
Thursday night and Friday the GFS/European model (ecmwf) are keying in on a 
stronger shortwave trough that lifts and erodes the cap. In 
addition...a cold front will probably accompany this system...so 
will show probability of precipitation increasing to 30-40 percent during this time. 
Otherwise will show temperatures gradually warming from the 70s 
middle-week to the middle 80s by Thursday and Friday. A slight cool down 
is expected next Saturday in the wake of the cold front.
