SEVERE WINTRY END TO JANUARY IN UK
Although mild weather with rain at times will dominate the UK for the next
few days, the final week of the month looks set to be dominated by a severe
plunge of winter, with hard frosts and widespread snow. The snow will
initially affect Scotland and northeast England from Monday 26th Jan, but
will then extend to most other parts by the middle of the week. Sporting
fixtures and transport are expected to be severely affected.

Lets hope it comes true!
