Tornadoes and Hail in Texas, April 30, 2019

Area Forecast Discussion
National Weather Service Midland/Odessa TX

.DISCUSSION...

At 18Z, WV imagery showed the upper trough over central NM, leaving
West Texas and Southeast New Mexico under SW flow aloft.  At the
sfc, obs put the dryline from near KROW-KCNM-KINK-KFST-Big Bend
Area.  This feature has begun mixing east over the past couple of
hours as winds have veered to SW-W in response to leeside troughing
on the Front Range.  High winds have so far failed to materialize in
the Guadalupes, but we're reluctant to cancel the current warning
until after peak heating/mixing.

Mesoanalysis indicates that, unlike 24 hrs ago, there is no cap over
the CWA this afternoon, w/sbcapes in excess of 2500 J/kg east of the
dryline.  Mid-lvl lapse rates of 7-8 C/km will maintain the hail
threat, and w/dcapes of ~1200 J/kg running right alone the dryline,
a wind threat is in the mix, as well. Further east, better 0-3km/0-
1km SR helicities are confined to the far ern zones, as well as lwr
LCL heights. Convection has already begun near KFST, and models hint
at bringing a couple of shortwaves thru the lwr Trans Pecos
overnight.

Zonal flow aloft follows the trough, and will persist thru the
weekend.  The dryline will stay generally along and east of the
Texas/NM border each day, w/a chance of convection along and east of
this feature.  Thu, a cold front will move into the area, courtesy
of a trough traversing the U.S./Canadian border.  This will bring
temps down closer to normal Thu-Sat.  As post-frontal winds veer to
east Thu night/Fri, they'll back moisture up against the wrn mtns,
expanding chances of convection further west.

Temps rebound to above-normal Sunday, and stay that way into the
extended under dirty ridging that transitions to SW flow aloft by
Monday as the next major trough approaches.  A chance of convection
will be possible over the weekend, but long-range models are out of
phase by this time, so we'll keep chances minimal.
