Temperatures will widely fall below freezing, something which has been largelly absent this winter. Temps may drop below -5C in rural areas. Remarkable to think that this could easily be the coldest night of the extended winter. 

Plus there are some very strong northern blocking signals emerging. Could april bring more snow than Dec,Jan,Feb combined? And does anyone know how unusual that would be? 

Depends on your location of course. My old stomping ground of the NYM snow in April is nothing unusal at all, had some heavy falls in April. Snow in early May is more unusual of course but I have seen happen at least 3 times.

I think one of the late 80's winters, possibly 1988 or 1989 brought April snow to my part of the world after a mild winter.

For the south of England I guess it would be unusual

I recorded no frost in "Winter" looking forward to reading my thermometer in the morning, best chance since Nov 26th !

It was -4.3C here on 12th March I guess we could come near that.
It's already down to 1.5C, a classsic clear + frigid spring evening after a wintry showers day.

Seeing -4*C predicted for my home location, with the odd run having managed a -5*C... that's totally bonkers considering that we've got above average soil temperatures at the moment 

To put it into context, a night of -5*C or below has only occured once in all of the springs I've recorded... funnily enough, that was in 2006, and not 2013 as one might guess.

Down to -0.2C here already.

Got down to as low as 2.3 C at 5.45 am even here on the coastal edge, frost had no problems in setting in by the early hours since skies were clear and winds remained calm.

-5.6C at 6am

Just on 0C here - we've had a couple of colder nights in the 'winter'

-2.4c

Coldest night of the Year/Winter/Spring

First air frost since 26th November

Frost drought is over

Certaintly looked like the coldest night of the 'winter' for many places. So here is a league table (montain sites are not included)

1) Resdale camp (northumberland 212m): -6.6C 

2) Eskdalemuir (Cumbria 242m): -5.3C

3) Aviemore (E highlands 228m): -5.1C

3) Topcliffe (Yorkshire 87m): -5.1C

5) Leeming (Yorkshire 32m): -4.8C

5) Strathallan (Tayside 35m): -4.8C

7) Loch Glascarnoch (W highlands 264m): -4.7C

8) Dishforth (Yorkshire 36m): -4.4C

9) Benson (SE england 57m): -4.2C

Yorkshire was suprisingly cold, the vale of york perhaps the UKs pole of cold last night away from the unsuprising frost hollows of resdale and the infamous eskdalemuir. Apart from this temperatures dropped sub zero pretty much everywhere excepting: SE coast England, much of W devon and cornwall, W coast of wales, W coast of scotland, NE coast of scotland, N coast of scotland, and large parts of N ireland. Inland though, temperatures of -2C or -3C were the norm. 

Also Ice day watch for the vale of york and central scotland, if the fog doesnt clear. Still -3C in dishforth. Now, does anyone know how unusual a late march night is, that eclipses the whole of dec-feb? 

-2'C last night in Reading.  Not sure that was our coldest night of the year.  I really should get a weather station of my own.

Minimum 0.2c at  03.11... Not  that cold...

-2.1c here at 06.10 this morning . Coldest temperature so far this year

-3.6'C - was probably 1st or 2nd coldest of the "winter" - will need to check!

Lows up to 0900 were

-6.8 Redesdale (could be coldest in England this winter, i think Benson had the previous low in November with a very similar figure?)

-6.7 Braemar (Aberdeenshire)

-6.6 Dalwhinnie (Central Highlands)

-6.3 Ravensworth, Topcliffe (N. Yorkshire)

-6.1 Drumnadrochit (near Loch Ness)

-6.5c Glenlivet, not an official site but a trusted one.

-5.7c here on my VP

-1.7c

3rd coldest temp of the 'winter'  (behind -2.4c and -2.1c)
