In addition to the passage of ITCZ over the region, the weather balloon launched from Hamad International Airport on Tuesday dawn indicated the presence of relative cold advection in the upper levels of the atmosphere, which helped the formation of thundery clouds with scattered light to moderate rain.
Identify whether you're in a warm advection or cold advection situation and use that to help understand what kind of precipitation might be encountered (see the cross section illustrations).
