- Quite a Quiet Weather Week
Not much in terms of weather this week as the upper trough is
replaced by ridging and surface high pressure much of the week.
There could be a frontal passage on Thursday but moisture appears
to be non-sfficient for any chance of showers. We will probably
have to wait until the weekend for any real chance of rain.
NOTE: The 2026 growing season will end this morning as soon as
the Frost Advisory expires.
