The Met Office warning says: "Possibility of heavy snow over parts of England, Wales and southern Scotland".
"Several cm of snow are possible, especially over hills, with drifting in strong winds".
"Down to relatively low levels overnight and that could cause a few problems certainly potentially turning things icy for Friday morning".
However, the warning adds that "it is quite possible that snow might not be too disruptive".
The weather warning was issued this morning, Thursday March 29, and will be in force on Easter Monday, April 2, between 00.15 and 23.45.
"There is a slight chance that some rural communities could become cut off".
Rain and snow showers are likely beginning around 5 p.m.in Denver, according to the National Weather Service in Boulder.
Fed raises rates, suggests more to come
"History has shown that unless the real interest rates rise beyond 2.5% the markets can very well take these hikes into stride". Tighten too quickly and inflation may not meet its target of 2% - the level the Fed sees as healthy for the economy.
"The south will be very wet during the early hours of Monday, then as this air moves over the colder air the precipitation will change to snow".
After a chilly, dry and bright start on Friday, outbreaks of rain will edge north through the day.
