After an unseasonably warm weekend, temperatures are set to drop to below freezing again this week, with snow possible from Thursday onwards.

Forecasters agree that from Wednesday temperatures are going to plunge again, with lows of -3, but they (surprisingly) don't agree about the chance of snow over the county.

The Met Office says 'confidence is low in details' as far as the forecast for the week ahead is concerned, but at the moment, sleet and snow is expected from Thursday onwards.

Met Office forecasters say Tuesday and Wednesday will be breezy, with outbreaks of rain. It'll then turn colder on Thursday, with blustery showers likely, these turning to snow on Thursday night.

Google's weather forecasting service says there's a 40 per cent chance of snow across south west Hertfordshire on Sunday, but not before.

Our own weather forecast predicts sleet for Saturday and snow on Sunday.

And the Weather Channel is also predicting snow showers across south west Hertfordshire on Sunday.

So don't get the sledge out just yet - but maybe check you know where it is. Just in case.
