Day 1 Convective Outlook RESENT 1

Valid 251630Z - 261200Z
...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS OVER PARTS OF THE
TEXAS COASTAL PLAIN...AND OVER PORTIONS OF NORTH DAKOTA....
...SUMMARY...
Hurricane Hanna may spawn a few tornadoes today and tonight over
parts of south Texas. Isolated severe gusts and hail are also
possible over parts of the northern Plains and Upper Midwest.
...TX...
Hurricane Hanna will move ashore over south TX early this evening.
As the system moves slowly westward, favorable vertical shear
profiles will move inland over the middle and lower TX Gulf Coast.
So far, convection has not shown consistent tendencies toward
rotating updrafts, and has been primarily outflow dominant. If that
changes, the potential will exist for a few tornadoes across the
SLGT risk area this afternoon and tonight.
...Central ND...
A surface cold front over eastern MT and northwest ND will sag
southeastward today, providing the focus for scattered thunderstorm
development. Southwesterly flow aloft is sufficient for a few
organized storms, with forecast soundings showing steep low-level
lapse rates - favorable for gusty/damaging convective winds. Have
opted to insert a small SLGT risk for this threat - primarily for
the 21-01z period.
