Severe Weather Discussion – 2008-14-4

Severe Weather Discussion for November 5, 2008.
Valid: 11/05/2008

Highlights:

– Severe thunderstorms are likely today, mainly along and east of
I-35. Primary threat across much of the area will be damaging winds.
However, in north-central and northeast Oklahoma there is a threat of
tornadoes, some of which may be strong.

– Enhanced wildfire danger will be present in the western 1/3rd of Oklahoma.

Discussion:

Strong upper system will move into the central U.S. today with an
associated dryline and cold front. The dryline will be the initial
severe weather producer as it moves east across the state later today.
To the east of this feature dewpoints are in the low 60s and
temperatures are expected to be in the mid/upper 70s. While the
moisture fields are not particularly impressive, there should be
enough instability to support severe thunderstorms. Wind speed and
directional shear aloft are more than sufficient for supercells.

Initial development should occur mid/late this afternoon along the
dryline between the HWY 81 and I-35 corridors. Storms will start out
discrete/isolated. These storms will have potential to produce
tornadoes as they race northeast. Later in the evening a squall line
is expected with the primary threat being damaging winds.

Probabilities:

None

Chase Status:

Rob and co may go out.
