But it's not all bad news.

While actual temperatures will be a far cry from rumours of near 30C there will still be comfortable highs of up to 22C - much warmer than it has been for the last few weeks.
But not all the UK will enjoy the warmer weather.
Temperatures could reach more than 16C this week in southern England - however easterly winds will mostly benefit western regions of the UK - particularly the South West, west Wales and western Scotland, which can look forward to warmer conditions.
Met Office meteorologist Simon Partridge said: "Average maximum temperatures will be about 16C, but we could see temperatures throughout the month a bit higher than that, particularly through this week.

"We will see eastern parts of the country slightly below average due to an easterly breeze, but overall in the west, high teens are likely and it's possible we could see the odd 20C.
"But we're not looking at anything much higher than that at the moment."
An unsettled April could give way to similar conditions in May as despite "drier than average conditions", spells of rain, cloud and damp are likely to push through and break up the sunshine.
However, it should stay generally dry throughout the month, with temperatures in the low 20s displaying "pretty good" conditions for this time of year, Mr Partridge said.

He said: "In the middle of the month, we are looking at things being slightly cooler but still around the average and by the end of the month, it will become warm or very warm - about five degrees above average, so 21C and 22C maximum."
The spring heat is in keeping with the slightly warmer than average trend experienced throughout the winter, the forecaster said.
This marks a sharp contrast to the snow and bitterly cold temperatures witnessed in late April, in which areas of northern Scotland froze in temperatures as low as minus 8.6C.
Parts of Cumbria chilled in lows of minus 5.5C and Wales saw sub-zero temperatures of minus 5.6C.
