Isolated Frost

Hi everyone, I've been lurking round here for a while, as I find it really fascinating, and have tried to advance my knowledge in the subjects by reading some of the posts in this part of the forum, it doesn't seem so bad! Very interesting read Mr. Data, I think that PDO affect Europe and the Arctic more than you would expect of an Pacific Oscillation system and it'll be interesting to see what affect La Nina will have on the Arctic this winter, especially a strong one.

So your value was really distorted by the 1988 figure! Overall, it looks like December is the real stand-out month for most people.

Yep, but that is actually the only December that had mean maxima above 10C (10.1C) since Records Began in the late 1800's. 5.9C is extremely do-able and it would be interesting in 10 years, as this decade has been colder than average, the 80's were above average, so if the next decade is below average, 91-20 could be very cool indeed.

Very interesting statistic here: At Durham Observatory, the period between 1971 and 1980 gave December an average temperature of 4.2C, in the period, 2001-09, our average in December is 4.0C. Using this, we've found that, a mean temperature of 5.9C this coming December would make the 81-10 figure less than 71-00 figure. So, December's have been cooler in the noughties than in the seventies.

I think Tonyh on General Weather Chat pointed out that -8C has been reached in Cymru, and -11C in Alba, at Dalwhinnie. Not so sure on the date, but I think he posted a link. Infact: Ta-da! Look at the bottom, it gives the record October lows.

Yep. Along with Tulloch Bridge and Woodford under -4C, Eskdalemuir at -6C, and Sennybridge at -6.1C. I got my first air frost since May 12th here, at -1.4C.

AO index - extremely negative NAO index - negative Very interesting to see what's happening with these currently, both positive during early October (warm spell in the UK). Also interesting. So, do you think the AO & NAO will remain negative throughout this winter?

Interesting that, here in Durham, we've been above average in the last 9 years! I'm going for a very much average 6.7C. Also, this retains the fact that I always guess the CET more than 5 days early! EDIT: I'll keep my 6.7C guess. The 1961-90 average is 6.5C

I'd say £350 is out of my price-range ATM, but that La Crosse looks quite good. I'd like to stick around with Oregon for a bit, but it's certainly #1 currently. EDIT: In fact, I've made my mind. I'll have the WMR80, as it has pretty much everything I need, pressure, dew point, heat index, temp., humidity, forecast, wind stats etc. I'd of loved the WMR200, but it is unfortunately on the rather expensive side. Decision made

1.9C -0.2C Dew Point Calm with a slight SW'ly 1026.8mb Scattered Clouds Low of -1.4C at 07:10. First Air Frost since May 12th, lowest temperature since March 11th.

Very nice to see the first SOUTHERN Sweden falls, can imagine that is quite rare for this time of the year. Good gains everywhere else and impressed with ice build-up so far.

Ahahahaha. Very nice!

Interesting note about March, it was only just marginally warmer here in the last 10 years than before. The fact that maxima have gone up more than minima, would indicate increased sunlight (and clearness) as minima of course are usually cooler under clear skies and maxima are warmer. Wouldn't it?

Isn't soft hail classed as graupel? EDIT: According to wiki it is. Look at the description at the top.

Of course, temperatures have slowly been rising in the last few decades, but are there months that buck the trend? Example: December - 1961-1990 (3.9C) December - 1971-2000 (4.3C) December - 2001-2009 (4.1C) Here are some stats from Durham Observatory, showing that, December has been cooler in the last decade, than in the period between 1971-2000. Anything below 2.5C as the mean for this December would mean that on a whole, this decade's December's have been as cold (or even colder) than the 61-90 period. Another one: October - 1961-1990 (9.8C) October - 1971-2000 (9.5C) Of course, the temperatures in October are also reflected in the CET average, with 71-00 also being cooler. May - 1961-1990 (9.9C) May - 1971-2000 (9.9C) May, is an oddity, a summer month which has the same average. However, there are some months with obvious warming trends. November - 1961-1990 (5.7C) November - 1971-2000 (6.0C) November - 2001-2009 (7.2C!) Do you keep any records of your temperatures, or have records nearby? Do you have months that buck the trend?

Not anywhere near what we expected, a high low (!) of 3.7C here, 4.6C currently, noticeable ground frost in the hills around here though. Also, OON, sometimes when I try to visit your website, it just won't let me. Any reasons as to why?

A bit of bumpage, for the people who still haven't had an air frost! Me included, my lowest since the June Solstice is 0.6C a couple days back, and it's likely I won't hit it tonight. But you never know, 4.1C at Durham currently. The Lake District/Pennines area should get a frost tonight - 1.3C at Shap already, many other stations on wunderground.com have got less there aswell. It's 1.1 at Great Asby (OON) along with Great Dun Fell (at 847m) reporting -2C at 21:50 (no update since then). Cold night for us Northerners!

My 9.8C (Nu Design) is looking good so far! I think it'll be exactly 10C ATM.

Ah, no! WMR80 = Not supported. Anyway, thanks for the help, but I may save up for a Davis or a Top-end La Crosse! Thanks alot though!

am afraid i'll have to bump this...

I know how you feel, the only down point on my beautiful N900

I am wondering about getting a WMR80, a new one, but does it work with Weather Display or Weather Display Live? Thanks.

Hahahaha, someone's just slipped in the snow
