On an early spring morning, maybe a week or two before Easter, the forecaster speaks of 'daytime temperatures very possibly edging into the mid-teens' in your region.
By British standards (rather than your own ~ if you, perhaps, come from somewhere rather warmer!), what is this probably supposed to mean?
The spring sun is 'trying hard' and there may even be a bit of warmth in the day; you may be able to dress a bit more lightly than recently.
There are signs of spring in the weather, but it is not yet worth thinking in terms of lighter clothing.
The forecaster would love to be able to tell everyone that spring has arrived at last, but the available data really don't confirm this at all strongly yet.
A wonderful, balmy sunny afternoon is almost certainly on the way.
