Station records

Mothman

This thread mayget lost quite quickly, but I still think it merits being created.

Today, 12th Aug 2008 saw lowest pressure in my records (since 1999) for June to September period. 983.8mb.
In fact only 3 previous occasions has pressure dropped below 990mb during summer. (June to July)
14.8.07 988.2mb
18.8.04 989.3mb
24.6.04 985.7mb

Also now on 15 consecutive days with minimum temperature above 10.0C. Easily a record

And 16 consecutive raindays (days with 0.2mm or more), a record for summer and not far off overall record of 19 days.

28th July to 8th Aug, 12 consecutive wetdays (days with 1.0mm or more) a record for summer, overall record 14 days

Danno

A low of 985.6hpa recorded here today. Will sift through the Weatherlink for more data in the coming days.

Lowest temperature so far this month was 10.6c - so thats 12 days of above 10c minima here.

Temp has just dipped below 10C (now 9.6!) for the first time since the morning of the 21st of July (although with a min of 10.1C on the night of the 1st), making 21 days of above 10C minimums.

Also recorded my highest hourly rainfall of 14mm on the 6th of this month, though as I only have my station a year that's not saying much!

Mothman

Chilly 7C this morning, so the run above 10C ends.

I've still a bit to go for Sugust rainfall record.
Still shy of 70mm, 99.5mm to beat, but it is my wettest summer on record, beating last year.

Same here - this morning was first time temp went below 10 since 21st July

My wettest summer on record, beating last year, and the way this month is going it may well be my coolest, wettest, dullest and windiest August on record

Supercell

Wettest month here since I moved to Annamoe -145.3 mm so far, 200mm + is likely by the end of the month.

Snowbie

For now it's been my wettest month with 170.1mm to date, but it shall go up before months end.

As with MM above i feel the same will occur here too.

Mothman

Also Wettest September on record with 136.6mm of rainfall. 18 rain day(s) in Sept.

Mothman

Not wettest, 107.8mm, drier than both 2000 and 2006.
By far and away the coolest. 12.9C mean, previous lowest 13.7C in 2002.
Records back to 1999, also dullest in my records (2004), though substantially more sunshine than August. 124hrs vs 94 hours in August.

Snowbie

New station record 00-24Z
Lowest October overnight min of 3.7C, previous of 4.4C (Oct 2005). Data going back 4 years(2004) at this location.
Records can be viewed here. Data updates automatically thanks to PhP custom tags created for me from the author of Weather Display.

However i think it will drop even lower over the coming nights before months end.
Coldest Day 6am to 6pm and coldest night 6pm to 6am should also be broken to day.
Mean temp for the month should also be broken.

arctictree

Yep, I'd say that will go lower by time the month is out. Mothman should also record some low October max'es. Only 4.4c here at 10am.

Mothman

14 grass frosts so far (to 27th), previous record 12 last year.

I expect more entries here before months end.

Danno

New station low of 1.2c here last night.

Snowbie

Several of my temp records should be broken before months end.
New October record overnight min of 2.2C temporarily, that should be broken again tonight.

Should also be the coldest day (6am to 6pm today) followed by the coldest night for October(6pm to 6am on Wednesday) also.

Lowest mean for the month too.

Mothman

With tonights grass frost, it'll bring total to 16.
0.4 hours short of sunniest Oct. (2004) Surely see that during next 3 days.

8.2C max today, lowest on record.

Lowest min to break is -0.7C on 24th last year. and lowest grass min to break is -5.6C on 24th 2002. Both under threat tonight, but only if wind drops.

Snowbie

Here's an obscure one I've just noticed.
This is not from AWS but from manual obs taken once a day at 0900z

The daily mean temp has stayed in double figures for past 7 days, and may be 8 days if temp reaches 11C today.

First time I've recorded 7 consecutive days with mean 10C or above for Nov to Mar period. 9 years of records

Usually the last and first occurance is Mid Oct and Late April, though last year it was early June

Mothman

29th Nov 2008

Air min -3.9C
Grass min -10.9C :eek::eek::eek:
Well below previous night which were both Nov records.

The grass min ranks 5th in my overall records and air min 10th.

A bit more on the grass, min. The only month I've recorded lower is Feb. Dec record is -10.3C and Jan -9.6C and the air min would rank 2nd in both those months.

slayer91

Extremely cold night here on the mid west. Recorded an all time low temp of -6.2 C. Looks likes it could bit every bit as cold tonight

Snowbie

3 new records. 1 for November and 2 Alltime.

Data back to 2004 from this location
Low min -0.9C new Nov record 30/11/08
Coldest ever day (6am to 6pm) 0.4C on 29/11/08, new alltime
Coldest ever night (6pm to 6am) 0.1C on 30/11/08, new alltime

Just reading in Met Eireann's summary that the coldest day you recorded Snowbie was also the coldest November day in the Dublin area since 1941 on the 29th:

Pretty remarkable achievment I think.

Cheers for that DE, just looking through the rest of my data and another couple of records also there that jogged the mem from your link.

Lowest max also here too at 1.3C on the 29th
Coolest mean for Nov too at 8.0C

Mothman

I recorded a sub zero grass min every day till 19th this month, another tonight brings total to 20 which is most I've recorded for December. Its very likely this month will exceed the 23 grass frosts of February 08 to become frostiest month in my records.
Air frosts totals 8 so far and I think the 12 from February 08 will stand as I won't see air frosts once the easterly kicks in.

Add the 3 grass frosts at end of November to the 19 gives 22 successive grass frosts which exceeds the previous longest run by some margin.

Mothman

27th Dec 2008
Min -4.6C
Grass min -11.1C
Both lowest on record for Dec, (Air 1999, grass since 2002)

Mothman

27 Dec 08
Sunniest Dec day (since 2004)
6.4hrs

Mothman

I've a bit of catching up to do as there have been plenty of station records during past month, but I'll mention one now.

Pressure has remained below 1000 hPa for more than the past 7 days and seems to be longest such period in my station's history (nov 99) and it will remain below 1000hPa for the next 48hrs or so.

Mothman

While I'm here, I'll mention the -6.0C recorded on 8th Jan, lowest temperature on record, after the previous night equalled the previous lowest of -5.6C.

Mothman

This month is wettest Jan in my records and is going to be the coldest month in my records after Dec being 2nd coldest month.

Mothman

5th Feb 25.6mm wettest Feb day on records eclipsing the 22.0mm on the 3rd. Previous highest in feb was c14mm

5th Feb 2.2C max temp, 2nd lowest max on records behind 2.1C on 28th Dec 2000.

Records back to Nov 99
