Wind Forecast:

Unsettled conditions will persist across the S UK & Ireland overnight. However, there exists a region of high interest across S England where there is the potential for a brief spell of strong winds - but large uncertainty remains in where this occurs.

Severe Weather Forecast:

2 main severe weather threats across the S UK during the next 24 hours. Large Uncertainty exists in the Red Zone, but the potential for severe weather is higher here. The blue zone has better confidence but any severe weather will be very hit and miss.

Storm Eowyn Forecast:

A major, generational, weather event is expected across the Republic of Ireland & the UK during tomorrow. Dangerous, hurricane conditions are likely across the Irish West Coast early on, with severe winds spreading into the rest of the UK & Ireland later.

Exceptionally impressive dry air signature with #StormEowyn, denoting descending dry air.

Stratospheric intrusion beginning overnight, & an exceptionally strong one to; ECM has dry stratospheric air basically at the surface.

Model output of 110-130mph somehow seems reasonable.

First time having 3 Capital Cities under a Red Warning from one event?

Severe Weather Risk: 8am-5pm Today

A band of convection will move East across the Southern UK through today, potentially developing into severe storms. Strong wind gusts, perhaps >60mph, and a few tornadoes will be possible.
January 23, 2025 at 7:05 AM
I will try have graphic/maybe a video out tomorrow morning for the tornado/severe weather risk.

But in case I don't manage too - upper level & surface pattern support what could be quite a severe threat with a line of very strongly sheared storms moving with a surface trough.

UKV 15z had a very extreme feature in the Channel on Monday. Not worth getting worried about at this point - small, secondary lows are often very hard to forecast and confidence is currently v low.

Wasn't the only model though - 00z GEM and GFS had similar. Worth watching imo.

Somewhat concerned about the potential for severe coastal flooding/storm surge on the west coast of Ireland on Friday morning.

Pressure <955mb, wind gusts well over 100mph and sustained winds of hurricane force currently being modelled quite consistently.

Storm Eowyn: Forecast Update 1

Storm Eowyn is currently expected to bring exceptionally strong winds to parts of the UK & Ireland, though uncertainty remains on the exact location and strength of the strongest winds. As such, this forecast is more confidence based as opposed to wind gust based.

Happy new year everyone!

Cautiously optimistic on the possibility of *slightly* more prolonged cold into January, driven by renewed blocking across the North Atlantic.

While uncertain, risk is highest across the North with possible mild incursions in the South 4-6th. Significant snow likely on the 1st.
December 29, 2024 at 1:46 PM
There is an increasing signal for significant snowfall on the northern flank of a (possibly deep) low on New Year's Day.

The main issue atm is the large uncertainty in the position and strength of the low, which determines where in the UK & Ireland sees the snowfall.
December 28, 2024 at 11:47 AM
A fairly interesting signal starting to emerge on the ECM mean pressure chart for the first week of Jan, with high pressure building across the N Atlantic.

Too early for specifics, but perhaps an increased risk of cold weather in the New Year, especially in the North.

And thanks for 100 followers!

It's worth keeping a fairly close eye on Saturday across the Northern half of Scotland - some models suggesting the potential for very strong winds, others slightly less so but it will be unsettled regardless.

Will have to watch for trends in the models as they will start to converge fairly soon.

Modelling is beginning to look increasingly "blocky" in the last few runs, i.e not a typical flat jet as you'd usually expect in December.

I suspect the MJO & AAM influence is beginning to come through, no significant cold *currently* on offer though.

2 years ago today - one of my personal favourite snow events, with an impressive (for me) 10cm of snow falling within just a few hours.

Perhaps even more unusual, the snow lasted on the ground for a full 7 days, which had a nice festive feel in the run up to X-Mas! Would be great to have a repeat!

Here's a look at all named storms that have impacted the UK since official naming began in 2015, including some named by other forecasting centres, coloured by the highest warning level issued.

The storm season runs each year from September through to the end of August the following year.

Today's storm in the UK stacked up against a few notable ones - plus Bert from earlier this winter. Looks like a good blow for SW / Wales. Away from the SW: quite a few other storms (Daria, Jeanett, Kyrill, Eunice) are likely far more impactful: from wind impacts at least #Darragh #StormDarragh

BREAKING: 2024 is now certain to be the warmest year in recorded history with an expected global average temperature of 1.60C marking the first full calendar year to exceed 1.50C.

Global temperatures remain significantly above where they should be despite El Nino having faded.
