The USA Disaster Situation Report
This morning we provided an estimate of tomorrow's risk of severe weather as
"Slightly Moderate."
This afternoon the Storm Prediction Center upgraded their risk of severe
weather for tomorrow from slight to moderate.
The reason why we provided a higher risk estimate in this mornings report,
than the SPC, was due to a high helicity index forecasted for the areas we
outlined as at risk. The current areas forecasted to have a high index
tomorrow are Central Oklahoma, eastern Kansas, northwestern Missouri and
central Iowa.
Below is the current
DAY 2 CONVECTIVE OUTLOOK...
VALID 131200Z - 141200Z
THERE IS A MDT RISK OF SVR TSTMS LATE TUESDAY AFTERNOON AND NIGHT

The current risk of tornado, hail, and severe wind are down from this
mornings estimates. The areas at risk are basically still the same, however
the probabilities are generally lower.
