until Last Quarter, because this is the time when the Sun
applies the most heat to the ground. There is more likelihood
of storm activity in general, that is, hurricanes and
typhoons, between Full and New Moon than between New
and Full.
This is a time for mainly daytime cloud and rain.
Lower in the sky in summer, the Moon creates an atmospheric
tide that is thinner in summer and thinner in the afternoon.
It may rain in the early morning, as the Moon sets.
Midday may be cloudy and the afternoon may be tornado
time in some areas. Rain is less likely in the evening and
overnight the sky will probably be clear.
Whirlwinds, waterspouts and a heatwave are high possibilities
just before the Full Moon in summer. In the winter
one can look forward to the prospect of daytime
snowstorms.
When the Full Moon is in Perigee, there is usually an
extra low atmospheric tide effect near midday. If it is summer,
very warm temperatures will result. But Moon in apogee
at this time can also bring a possible heat wave. At the
solstice the weather patterns slow down.
