Areas affected...Northeast Texas...Far Northwest Louisiana...Far
Southeast Oklahoma...Southwest Arkansas

Concerning...Severe potential...Watch possible

Valid 052319Z - 060115Z

Probability of Watch Issuance...60 percent

SUMMARY...A severe threat is likely to develop early this evening
across parts of northeast Texas, far southeast Oklahoma and
southwest Arkansas. Large hail, severe wind gusts, and an isolated
tornado threat will be possible. Weather watch will likely be needed
once convective initiation takes place.

DISCUSSION...Surface analysis shows a cold front from southeast
Oklahoma extending southwestward to near the Dallas/Fort Worth Metro
and into north-central Texas. Along and ahead of the front, a field
of cumulus is evident on visible satellite imagery. Low-level
convergence is likely maximized near Fort Worth, where a boundary
from the southeast recently merged with the cold front. Short-term
model forecasts suggest that cells will initiate near the front
early this evening from the Dallas/Fort Worth Metro northeastward
into northeast Texas. Ahead of the front, moderate instability is
analyzed with the RAP showing MLCAPE in the 2000 to 3000 J/kg range.
In addition, the WSR-88D VWP at Fort Worth has 0-6 km shear near 70
knots. The RAP has 700-500 mb lapse rates in the 7.5 to 8 C/km
range. This should support supercells with large hail, and
hailstones greater than 2 inches in diameter will be possible. The
storms may also be associated with severe wind gusts and an isolated
tornado threat.
