More Predictions of Cold Weather

Wednesday, November 23rd, 2011

Two more predictions for very cold winter weather have come to light. Neither has much of a record of accurate predictions that I’m aware of, but each one presents at least some reasoning for their forecasts.

The first is from Christopher Nankervis, who writes for weatherlogistics.com. His forecast for the UK gives a good bit of reasoning (including a 14-to-21-day teleconnection with the US East Coast weather, which I’ve observed myself), and this chunk of prediction:

A deep cold snap over the East coast of the US points toward an abrupt and intense Arctic-type weather scenario in the UK in 14 to 21 days time. This deep freeze may see temperatures plummet, with significant widespread snowfall and perhaps blizzard across Britain during mid-December 2011.

Meantime, Harry Kershaw, described in the Manchester Evening News as an “amateur weatherman” who bases his predictions on matching patterns with historical weather, is reported thus:

he fears this winter could be as cold as that of 1812-13

The article goes on to quote information about Moscow and Napoleon’s retreat in that winter. Now, if Mr. Kershaw is matching patterns, he’ll also need to match the geography, so quoting Russian winters in comparison seems to miss the point. There are very few direct quotes, though, so I suspect the Manchester Evening News has boosted the signal a little. Oddly, in this part of the world, 1812-13 doesn’t seem to have been all that terrible, although there was a foot of snow in March in Edinburgh. On the other hand, the Thames froze over in 1811, and again in 1813-1814 – which was one of the most severe winters on record.

So if Kershaw’s pattern-matching theory is correct, this coming winter should be chilly but manageable, and then 2012-2013 should be extremely cold. There are more predictions for cold this winter than otherwise, so we’ll see.

Mild Autumn

Tuesday, November 15th, 2011

Are we going to get some proper winter weather before the end of the year? There’s no knowing what December will bring, but predictions out to the end of November are looking for things to remain fairly mild, if getting a bit more unsettled as the days go by.

The Guardian has two articles which are relevant and interesting; one about the weather in October, which was unusually warm across the UK, and one about the same in November, which is set to be the mildest in 300 years (and therefore the mildest on record), unless something changes drastically. Temperatures above 15°C have happened in a few places in Ireland, which is downright strange.

It is, of course, still autumn in meteorological terms; December, January and February are the real winter months, and while it’s mild now, that really has little enough bearing on the weather through the rest of the season. Peter O’Donnell’s forecast has January as the coldest one, which is much more in line with the “traditional” British Isles winter. I do feel like I’m about ready for some colder weather.

Winter Ready?

Wednesday, November 9th, 2011

I see the Department of Defence are copying me.

More seriously, the Office of Emergency Planning have put together a website about being ready for and able to handle winter weather, and in light of the winters we’ve had the last two years, I can’t see this as a bad thing. They cover a good few topics, although the information is provided, for some unknown reason, as PDF files – even the weather forecast!

I can’t see it being a hotspot of new or up-to-date information, to be honest, but it’s not a bad one to start some basic winter preparations.

First Frost 2011 7th November

Tuesday, November 8th, 2011

The weekend just gone was clear and cold over most of Ireland, and we saw our first frost on Monday 7th of November. There were a few areas reporting frost on the 6th as well, so take your pick. That’s quite late, as first frost dates go; we’ve normally seen a few frosty mornings by early November, and it’s not impossible to have frost in late September, although I haven’t seen it for years.

The weather has returned to unseasonal warmth now, and that looks set to continue for about a week. There are indications of a colder period to follow then, although as ever, anything more than three days out should be treated as speculation.
