Increasing high and mid level clouds are expected across

some lower clouds that will be impacting mainly DIJ overnight
and Tuesday morning, as a weak storm clips the Divide. At the
moment, the potential for light precipitation is under 10%, so
we will only indicate scattered to broken low clouds BUT remain
VFR.
