Later this week the weather is set to turn much colder, this is typical of this time of year and is very good (predictable weather makes gardening so much easier)....certainly nothing to be concerned about.
In fact, It does illustrate clearly why mid-Oct is the preferred time to sow those SP seed i.e. taking advantage of the last of season's warmth to germinate the seed, then the onset of cold weather to make them mark time until probably next March.
Of course, the seed can be sown right up to Christmas (after that you might as well wait until March) but a little heat (10/15C) will be needed to get them started.
