NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Fort Worth Texas 
531 am CDT Sat Apr 25 2015 


Aviation... 
VFR will prevail through the period with just some high clouds. 
Light south/southwest winds early this morning will become 
west/southwest after sunrise. Speeds will increase during the 
day...rising to around 15kt this afternoon. Speeds should remain 
low enough to where Crosswinds will not impact rates on north-S 
runways. Winds will diminish after sunset to 5 to 10 knots. Tr.92 


&& 








Synopsis... 
the upper low responsible for Friday/S severe weather continues to slowly 
inch towards the east across the central and Southern Plains. After 
a very brief respite from the recent active weather on 
Saturday...attention will then turn to the latter half of the 
weekend and early portion of next week...where a couple of severe 
weather episodes will be possible. Thereafter...conditions are 
expected to become more tranquil after the passage of a cold 
front around mid-week. 


&& 


Short term... 
drier air should continue to work it/S way into the region as the 
dryline/Pacific front slowly push eastward as the upper low lifts 
out into the Ohio/Tennessee River valleys. For this morning...will maintain 
slight chance probability of precipitation across our far southeastern zones where the drier 
air has yet to reach. In addition...radar trends across The Hill 
Country suggests that a few showers and storms may drift into our 
far southeastern zones. West to west-southwest winds should support 
some of the warmest temperatures we have seen so far this year due 
to the compressional warming associated with the downslope regime. 
While Waco/S record high temperature of 94 degrees set back in 
1996 will likely remain out of reach. The record high temperature 
of 91 set back in 1925 at dfw will be threatened. For now...have 
kept temperatures in the upper 80s across much of north/central 
Texas with a few 90s out across western zones where the relatively 
drier air will allow for slightly greater warming. Skies should 
be clear as drier air aloft overspreads the area...and today should 
be a nice day for outdoor festivities. 


Heading into Sunday morning...low level warm/moist advection 
should be confined to far southeastern zones as the upper low that 
is now across the Pacific northwest moves closer to the region. 
Temperatures will vary region wide tonight as areas along and 
northwest of a Comanche to dfw to Paris line should remain 
slightly cooler with the drier air...compared to areas across the 
southeast where low level warm/moist advection /courtesy of a 
south to southeast wind/ will begin and should result in a slight 
increase in cloud cover to limit nocturnal cooling and perhaps a 
few areas of patchy shallow ground fog across our southeastern 
zones. 


On Sunday...a very impressive upper trough /characterized 
by nearly 80 meter height falls/ is forecast to amplify across the 
Great Basin. The resultant southwest flow across the Lee of the 
New Mexico rockies should induce low level cyclogenesis. As the 
upper low closes off somewhere over New Mexico...the surface 
cyclone should deepen quickly. In response...moisture transport 
across area should increase. With around 50 knots of middle level 
flow...the very diffluent regime aloft and with the boundary layer 
moistening...the stage will be set for another round of severe 
weather. Taking a closer look at the areal extent of the best low 
level moisture...it appears that most of the coarser models are 
fairly consistent with bringing 65+ degree dewpoints into our 
southern zones. This appears plausible as there have not been any 
recent intrusions of Continental air down into the western Gulf of 
Mexico recently. While a Stout cap will be in place...30 to 40 
meter height falls /indicative of large scale ascent/ will 
overspread western zones on Sunday evening. A dryline is expected 
to sharpen somewhere across the Big Country during the afternoon 
hours on Sunday. Low level convergence coupled with the favorable 
dynamics should prove sufficient to overcome the cap. Steep middle 
level lapse rates should yield a very healthy instability profile 
/3000+ j/kg of cape/ and 0-6 km bulk shear values of around 50 
knots should Foster supercellular storm structures. With the steep 
middle level lapse rates and a very "fat" cape profile...large hail 
appears probable. In addition...the strengthening of the low level 
jet /winds of around 30-35 kts/ around the 00-03 UTC time frame on 
Monday will support a rather substantial tornado 
threat...primarily across our western and southwestern zones. For 
now...it appears that the best chances for precipitation will 
remain confined to areas west of the Interstate 35 corridor on 
Sunday afternoon and Sunday evening...with precipitation likely 
overspreading the rest of north/central Texas Sunday night into 
Monday morning. 


&& 


Long term... 
on Monday...more numerous shower and thunderstorm activity can be 
expected as the Pacific front/dryline nudges eastward as the closed 
low slowly treks eastward. A cold front will also sag southward 
through Oklahoma before stalling out somewhere along the Red River. 
Parameters for severe thunderstorms on Monday appear favorable...but 
with the lack of any convective inhibition...it appears likely that 
a very messy convective scene will unfold. That being said...deep 
layer shear will still support organized thunderstorm structures 
capable of large hail and damaging winds. Similar to Sunday...the 
kinematic structure may also support a tornado risk. In 
addition...heavy rain will be possible along the slowly sagging cold 
front....especially along the Red River...and east of the Interstate 
35 corridor. The cold front should sweep through all of 
north/central Texas by Tuesday...ushering in cooler temperatures 
and drier conditions. After a fairly active weather pattern...it 
appears that more tranquil conditions will be in place across 
north/central Texas as a shift to more of an Omega pattern 
/ridging across the central US with troughs along the coast/ sets 
up for the remainder of the forecast period.
