In Britain, the prevailing winds are westerlies and the sun, of course also sets low in the west. A �red-sky' evening means the sun is setting in a cloud-free area, whilst any lit-up clouds are overhead the observer or already to the east of him. If the western area is cloud-free - since that is generally the weather-state headed our way because of the winds - tomorrow should be clear and fine. In reverse, in the morning, a low sunrise to the east illuminates clouds above you or to the west. Again, they are probably what is headed your way and the likelihood of rain is high.
It seems, therefore, that the two conditions - red at night and red again in the morning - are unlikely to occur together.
