Severe Thunderstorm Watch #001

The Weather Centre
3:42 PM CST
March 8, 2012

A Severe Thunderstorm Watch has been issued from The Weather Centre headquarters.
This watch is effective immediately until 6:00 PM CST.

At 3:42 PM CST... elevated thunderstorms were ongoing across the area highlighted for this watch.
These storms are riding on 20 to 30 knots of wind shear, making for a minimal tornado threat. Instability is elevated, with values of 2000 j/kg being observed across Texas, with lesser values to the north and west.
Seeing as negative Lifted Index numbers are to the south of the thunderstorms, this severe thunderstorm watch is not a major one.

This frontal boundary will continue to move in an easterly direction, bringing the storms along with it. Hail and damaging winds will be the main threats, with a minimal chance of a tornado. A special index displayed by the Storm Prediction Center called the MCS Maintenance index is indicating a 60-90% chance of conditions being supportive of additional severe thunderstorms down the road.

As expected, these storms will weaken in the next several hours as the main instability is to the west and south, away from the line of storms at this time.
