The big freeze is set to tighten its grip on the city for the rest of the week with more snow and plummeting temperatures on the way.
A number of schools and nurseries were closed in south Birmingham and commuters were urged to take care following a scattering of snow showers.
Temperatures will hover around the zero mark until the weekend, when they could rise to a meagre high of 4C.
Billy Payne, forecaster from MeteoGroup, said: “It looks like another bitterly cold day today with temperatures struggling to get above the zero mark.
“There are going to be a few snow showers billowing in from the North Sea.
“There will also be an additional accumulation of snow of around a couple of centimetres in places.
“Tomorrow there will be a widespread frost and temperatures will be as low as zero to possibly -1C during the day.
“It will be a mostly dry day with wintery sunshine.
“Tomorrow night there will be a band of sleet and rain spreading from the east across the country and hitting the Midlands. There could be a risk of sleet in Birmingham.”
Mr Payne said a tiny respite from the bitter cold could come at the weekend.
He said: “Early sleet and snow will clear away on Saturday leaving some sunshine. There will be a rise to 3C or even 4C. It does stay very cold thereafter and there will be a risk of rain coming up from the south.
“The general outlook for the early part of next week is that it will stay very cold.”
Birmingham City Council had a fleet of 28 gritters working round-the-clock to keep the roads moving.
The council also warned the public not to walk or skate on any ice-covered park lakes and ponds during the freeze.
Councillor Martin Mullaney, cabinet member for leisure, sport and culture, said: “We don’t want to ruin people’s fun but would remind people that when pools and lakes freeze over there is a grave danger that this will lead to people falling through the ice into freezing water.”
Gritting teams in Walsall are also working 24 hours to ensure the borough’s roads are safe for motorists.
Gritters went out on Monday night and then again early Tuesday morning spreading 75 tonnes of salt on the roads in addition to the 120 tonnes of salt spread last weekend.
The bad weather forced the nursery and reception part of Slade Primary School to close due to heating problems. Harborne Primary School was closed for the week due to heating problems. Baskerville school in Harborne had heating problems on Wednesday, in its residential section, so residential students worked with day students.
