Severe Weather Warning

I have been sent this today.

Normally we would wait to get more accurate forecasts and assess the situation closer to the time.
However, with the Easter weekend approaching and many colleagues not being in the office on Friday, we have decided to publish this Warning earlier than ususal.

The situation will inevitably evolve over the next few days and we may end up with no issues at all, but …forewarned is forearmed.
The Risk assessment is that there is a very small chance of medium level impacts

Initially, temperatures will be high enough that any precipitation will fall as rain tonight and tomorrow. It’ll feel cold in a brisk north to north-easterly wind on Saturday. By Saturday night and into Sunday it’ll be cold enough that we’ll start to see some snow on high ground in the Pennines (non-disruptive at that point). By Monday morning there’s an increased chance of more widespread snowfall giving a few cm of snow at low levels, and more significant amounts, with drifting on higher routes. Travel delays are possible, with a small chance of stranded vehicles and passengers, power cuts and rural communities becoming cut off.

With it being a Bank Holiday Weekend, roads will no doubt be busy, and there may well be a number of outdoor events planned. Conditions look potentially very dangerous for anyone who isn’t suitably prepared up in the Pennines, Cheviots, Moors or Dales.

The Cold Weather Alert Level has been raised to 2 (Alert and Readiness) for Sunday, Monday and Tuesday https://www.metoffice.gov.uk/public/weather/cold-weather-alert/#?tab=coldWeatherAlert

We have a Yellow Warning of Snow in place (very low likelihood, medium impacts), valid for much of the region all day on Monday (although large parts of low-lying NE England are excluded). There is still a good deal of uncertainty in the details of the forecast, but the cold and unsettled theme is much more certain. Details will become clearer in the next day or two, and warnings will be updated to reflect new data as it comes in. It’s going to be very important to keep abreast of the changes, so please keep up to date on Hazard Manager, our app, or website. Here are some links you may find useful…

National Severe Weather Warning Service
Chief Forecasters Assessment
As a weather system moves in from the south and comes up against cold air over the UK, there is the chance that rain could turn to heavy snow in places. Several cm of snow are possible, especially over hills, with drifting in strong winds. There is also the possibility of a few cm of wet snow gathering at
lower levels. At present the extent and amounts of any snow are very uncertain, and it is quite possible that snow might not be too disruptive.

The Met Office have issued a Yellow Warning of Snow
Valid from 00:15 on Mon, 02nd Apr 2018 until 23:45 on Mon, 02nd Apr 2018
Headline: Possibility of heavy snow over parts of England, Wales and southern Scotland,
especially for high ground. Travel may be affected.
What To Expect: There is a small chance of travel delays on roads with some stranded
vehicles and passengers, along with delayed or cancelled rail and air travel.
There is a slight chance that some rural communities could become cut off.
There is a small chance that power cuts will occur and other services, such as mobile
phone coverage, may be affected.
