[html]MD 0475 CONCERNING SEVERE POTENTIAL...WATCH POSSIBLE FOR PORTIONS OF CENTRAL INTO NORTHEAST TX
Mesoscale Discussion 0475
NWS Storm Prediction Center Norman OK
1157 AM CDT Wed Apr 13 2022
Areas affected...portions of central into northeast TX
Concerning...Severe potential...Watch possible
Valid 131657Z - 131830Z
Probability of Watch Issuance...40 percent
SUMMARY...Strong to severe thunderstorms producing hail and damaging
gusts are possible the next several hours across parts of
northern/central TX. A watch may be needed for portions of this
area.
DISCUSSION...Clusters of thunderstorms are developing along the
eastward-advancing cold front from north into central TX as of
1630z. The downstream environment has warmed into the mid 70s to
near 80 deg F in an area of clearing behind morning
convection/cloudiness and ahead of the cold front. Surface dewpoints
also are in the upper 60s to low 70s F beneath modestly steep
midlevel lapse rates. This is resulting in 1500-2500 J/kg MLCAPE.
Effective shear greater than 40 kt will support organized storms
with an attendant threat for large hail and locally strong gusts.
Low-level shear is expected to remain modest and overall tornado
potential is expected to remain low as a result. The overall threat
should decrease with southward extent as large-scale ascent
decreases. However, a small corridor of severe potential across
parts of north-central into northeast TX may require a severe
thunderstorm watch to the west of Tornado Watch 120, though any
stronger convection that develops closer to the Red River should
quickly shift east into WW 120.
