...Cold Air Funnels possible this afternoon...

Reports of a cold air funnel cloud reaching the ground have been
received from the Casper area this afternoon. Colder air and
convection behind yesterday`s cold front have brought a good
combination for these cold air funnels to develop briefly. Any
funnels that do form will have difficulty reaching the surface,
and any that do reach the ground are expected to only bring very
brief gusty winds and blowing dust.
