Snow showers possible in Nothern Ireland as the mercury plunges
British summertime may have arrived, but this week may feel like winter is coming back as the mercury plunges.
Forecasters are predicting the possibility of snow today, with wintry showers and a cold north easterly wind making daytime temperatures feel close to freezing.
The Met Office said today could be bright and showery with sunny spells.
However, the showers will be heavy, perhaps wintry and thundery at times, with snow on hills.
The maximum temperature is expected to be 9C.
The outlook for tomorrow through to Friday is little better.
It is expected to be a rather cloudy and showery few days.
Again, those showers will be heavy at times, with snow on the hilltops.
BBC NI weatherman Barra Best said: "We have to remember it's still springtime, despite what the change in the clocks suggests.
"It's only summertime according to them.
"It's always been more likely that we get snow at Easter rather than Christmas, and Easter's still a couple of weeks away.
"Early April is always a transitional period in weather for us, so there's always every chance it can still feel like winter."
Across the UK, some areas are bracing themselves for temperatures as low as -5C.
Met Office forecaster Craig Snell said: "It's going to be a very different week to the week just gone."
