- No need for a heavy coat: it will be milder than Thursday
Reliability is good for Friday: the models agree on morning rain, an afternoon lull and the cold front passing through in the evening. The exact time of the evening showers arriving may vary by one to two hours. For the weekend, a return to dry and bright weather is confirmed.
