Valid 031200Z - 041200Z


Isolted strong to damaging wind gusts will be possible later Tuesday
afternoon and early evening over eastern Oregon. A few strong storms
with gusty winds may occur over a portion of the Gulf Coast States
Tuesday, but overall severe potential appears limited.

...Eastern Oregon...

Upper ridge will remain centered over the Southwest States Tuesday,
and potential will exist for weak impulses to move through OR along
the northern periphery of this feature. A weak front will move east
into central OR during the day. East of this boundary dewpoints will
mix down into the 40s F with strong diabatic heating and steep lapse
rates supporting 300-600 J/kg MLCAPE. Isolated to widely-scattered
thunderstorms will likely develop as the atmosphere destabilizes
during the mid to late afternoon. These storms will be high-based
with updrafts rooted near 600 mb. Very steep lapse rates and deep
inverted-v thermodynamic profiles in the sub-cloud layer will
support a threat for isolated downbursts with some of this activity
through early evening.

...Gulf Coast States...

Multicell thunderstorms will once again develop along and south of a
near-stationary front from southern TX through the Gulf Coastal area
into the Carolinas. Anticipated widespread clouds and ongoing areas
of thunderstorms will limit substantial destabilization over most of
this region. Where pockets of heating can occur, some potential will
exist for storms to produce a few locally strong gusts. However, the
overall severe threat in this area will remain low.
