First Air Frost 2008

Danno

When and at what station will we see the first Air Frost of the 08/09 season? Perhaps, a few bonus points for the league could be picked up? Ideas anyone?

Birr - October 10th

How about bonus points for the first poster to post about an air frost at their location? (No cheating!)

squonk

How could you verify that? You know, if the night was just in or around allowing an air frost with temps but wasn't quite up to it but you happen to be in the midlands in a sheltered spot and do get an air frost.... such a person would be accused of cheating! You'd have to have weather station data to back your claim up and not many have those!

17th October birr,casement.

Danno

BeGeepers you know winter is coming when people like "Snow Plow" start posting!

PS: He/She used two locations!

Supercell

Alright since ye asked, extra 5 points for the first air frost date and another 5 if you get the location right..if two places get it same night, lowest temp wins.

The winning entry is Casement 7th October .

Deep Easterly

September 28th at Claremorris, gaurenteed

Edit, hugely depends on an continental easterly, which seems to be a thing of the past..

I'm no weather expert by any stretch but very kean on the subject.
Is it possible we could see our first frost if this scandi high develops over Ireland?

Damn, was banking on taking timed readings so the easterly hit dub AP first.

On the twelfth night of October there will be an air frost in Birr.:cool:

I predict an airfrost at Johnstown castle on the 8th of October.

7th October, Casement

I'd not be surprised to see a touch of ground frost at least tonight in one or 2 spots, there is a real dry chill outside. Birr or Ballyhaise most likely or maybe even Claremorris We'll see.

Deep Easterly

And sure enough, Birr's grass temp fell below zero on that night. -0.4c, the first ground frost of the season. Claremorris almost made it at +0.4c.

Fingers crossed that air temps will follow soon.

Snowbie

It will come close in the midlands and west this week for an air frost to develop.

But i'll go with Dubin AP 31st Oct

I hope so Snowbie. If I recall rightly, there was quite a frost one morning around this time last year, with the temp as low as 1.2c. Got down to 3.3c here this morning, and indeed, as I drove through my hometown Tuam this morning I think it would have been even colder there (a notorious frost pocket due to being relatively lower that the surrounding countryside) as there was the faintest hint of frost on the roofs. I don't think it will be as cold over the next few nights though, as I think cloud will increase generally. But that is my pessimistic streak again.

Supercell

I recorded 2.6°C here on the 18th last year so probably had a ground frost that morning. The season is definitely upon us. 8 weeks from now temperatures above 10°C will be a bonus

DOCARCH

Down to 2c atm in Birr - getting closer! And 1.5c at Pallas Green at 7.20am according to NRA.

Not very scientific, but I was working at the ploughing championships last year near Tullamore, and there was a significant frost at 7am one of the mornings - ice on the car and fields all white. Not sure what qualifies as air frost, but it was damn cold! Would have been around the 25th September...

-0.0C is an airfrost. Air temp is measured at 4feet above ground, so when the air temp at 4 feet is below 0C it is classified as an airfrost. Ground temp can be as much as 5 or 6C lower than this depending on other conditions but more especially on the crisp clear nights.

StratoQ

Mullingar getting very near an air frost.

1C now at 10pm. Humidity is high - so rate of drop has slowed - but still would say it will dip sub zero by around midnight.

Up to 2C at 11pm

DOCARCH

NRA reporting Air Temp. -0.8c atm (0600) at (N2) Reaghstown.

I'm at 5.1c atm.

Mothman

This morns mins
Dublin AP 1.0C
Mullingar 1.1C
Casement & Birr 2.8C

My AWS recorded 0.8C but official min from the screen 1.3C with grass min -4.3C.

Danno

3.0c here last night.

Mullingar - Oct 21st

In case you forgot Dan, conditions look to be slightly in favour of an airfrost tonight Dan but will it get close to 0C before midnight?

Temps tumbling around the country atm and dewpoints are fairly low but humidities are on the up. But I'll go for temps between 0.5C to 1C at one synoptic station in the east and midlands overnight.

Supercell

Too windy here for frost tonight unless it drops off, temp around 6°C for several hours now.

Snowbie

Aye same here, temp around the 7.5C mark for over an hour but my air is maritime moving in over the city on a SW'ly.

Danno

Tonight is the 21st night of the month, got until 9am

Danno

Grrrr, what a night for batteries to die in the console, grrr. I bet there will be a frost and I cannot record it... aaaaargghh!

Oh dear, professional weather station with cheapy batts is a definite no no:eek:

Danno

Got it back online, found a spare C battery and put it in. Low Console Batteries is a [better] forecast than "increasing clouds, precip possible within 12 hours"
Definately DURACELL to be purchased tomorrow - but I hate that evil bunny, kinda like a pink version of that snow rabbit I've seen mentioned here a few times

//thread is really gone OT - Sorry!//

Back OT

Will there be a frost tonight then?

DOCARCH

NRA currently reporting 0.0c at Kilkenny (at 0500).

Maybe if MetE still had their station there we would have an official first air frost!

NRA currently reporting -0.3c at Kilkenny (at 0600).

The NRA station is not located in the city centre though as was the ME equipment(Iirc the castle? mothman?).
City centres/town centres tend to be slightly warmer than out in the sticks.

Was aware of that. Thanks. Anyway.

Dublin AP reporting 0c at 1800 - this, as far as I am aware, is the first official air frost of this winter.

Alright since I'm the closest, how many points do i get from my astonishing prediction made back in September. So how about it my fellow league buddies friends mates, do you agree i should be awarded max points for this closely studied prediction made under pressure from all you excellent weather league participants 6 weeks ago.

nacho and trogdor no need to answer straight away

:)Supercell, how about it me auld mate, my right honourable buddy.:)

Not quite yet. +0.4c was the lowest Dub Airport got down to by 6 pm. Will have to wait til 7 pm for the first frost. :pac:

Edit, which is at Casement. -0.8c at 7.pm.

Quite correct!

Mothman

The +0.4C gets rounded to 0C for the text obs on the website.

Little doubt that Casement will be joined by Dublin AP and many other locations in having air frost tonight.

Danno

So Casement grabs it with -0.8c at 7pm.

No points, we all loose. Tough!

I insist on points to Snowbie though. If refused, revolt may ensue.:)
