Turning colder from Monday - wintry showers on high ground

darkman2

...Also there is a slight risk of wintry showers too. The jet stream will be taking a bit of a holiday allowing depressions in from the Northwest. This could lead to a Northerly flow of air sourced from just East of Greenland and further North. The models are all over the place with how potent such a flow might be but it should allow the first real frost and it will feel much colder. Perhaps wintry showers later next week but that is up in the air atm (except on high ground!). Pardon the pun. It will feel alot colder though and temperatures are very unlikely to break 10c anywhere. It will turn more unsettled also with periods of rain becoming common again after our flirt with a continental high pressure this week. So the first "cold spell" is on the cards:)


I will post charts for you nearer the time. Quite an interesting period coming I think none the less.

It's still rather humid and warm and likely to get warmer before next weekend. Will be quite nice later this week. Enjoy it. It is coming to an end.

how the F**k is that supposed to happen eh hasnt stopped raining up here for 4 days (whats this the rte dublin forecast )

wildefalcon

So, for the ignorant like me, that chart shows the "forecast" temperature 174 hours out from the date of the chart, right?

How does the pressure factor in?

Can't wait for this warm humid stuff to end!

It hasn't rained here since Thursday when 1mm fell :pac:

On a general note, it would have been good for farmers if the current mild dry weather that we have here in the some parts held on till the end of the month.

Bring it on !!! Everything is rotting where it stands, even the wood that's supposed to be drying out is having mutant fungi growing on it

Looking at the latest charts, it doesn't look anything out of the ordinary.

Still colder though

cherryghost

Defo, a drop of about 5 degrees nationwide daytime, well into single digits for nighttime temperatures.

dsmythy

Sounds like more typical October weather.

Speak Now

Definite cooldown on the way alright next 5/6 days, good late october weather

So where are we on the plan to remove all Irish snow shields...like for example the relocation of the Isle of Man? :pac:

Ok folks! .. I gonna throw in an arm and a leg for this one. :rolleyes:

Current trends are showing a cool down from Sunday onwards ,
in the northern areas temps could be a max of only 8/9 o C .Frost and the first sub zero temps seem likely.





Current models are showing the potential for some wintry showers on high ground on Wednesday/ Wednesday night. Will be interesting to see how the cold front coming through actually pans out. Alot of reports of snow / sleet could turn out to be hail once again . SO boardsies in the North.... EYES PEALED!

Thoughts and comments from more EXPERIENCED snow forecasters ... "HINT HINT DM2 "


LET THE EXCITEMENT BEGIN !

Su Campu

Dare I mention the possibility of a P**** L** forming in the cold northerly flow south of Iceland during the week. 500 hPa temperatures around -35 °C may be low enough at this early stage of the season, with seas still at their warmest.

There's more here

Remember any reports to be accompanied by photographic evidence to save all the sensational outbursts and the likes!

Dare my friend, DARE ! :pac:

GFS going for snow to fall in the north west!



Maybe on the top of Mt Errigal but I cant see anything much lower than that, we get -4 temps plenty of times from PM lows throughout the winter that don't give any real snow. If you swapped the height of the Donegal and Kerry mountains it'd be a different story but unfortunately nothing higher than 800m around here!

Still, the first real chance of the season, will definitely be keeping an eye out if I'm anywhere near the mountains

The actual cold front that is forecast to affect Ireland on Monday morning/afternoon has the potential to be quite nasty:



Could be some squally conditions in places as it moves through.

Su Campu

I'd worry about snow from the north when we have reports of temperatures above 30 °C in the Faroe Islands! :rolleyes:

Thetonynator was right, there was already a thread running on this cold snap so I've moved Ian's thread over to this one.

Pangea

It said on the forecast that Monday will be a washout with squally conditions.

Deep Easterly

This chart shows the 11 year average (00-10) of daily MSLP and mean temperature values at Belmullet for the month of October:


Data: Ogimet.

Based on this 11 year average, the 20th of October is statistically the coldest day of the month with a daily mean of 9.5c. Interesting to note also that daily mean sea level pressure values tend to (statistically) fall sharply during the 2nd half of the month.

What is really interesting though is that generally speaking, the October 2011 trend for both elements seems to be following this 11 year mean pattern so far.

Consistent upgrades on the gfs over the past few days for wind strength, looking like quite a stormy day for us in the north

Iancar29

Slight upgrade as to a larger area potential for some wintry showers on Wednesday , would LOVE to a snow covered Kippure this early
Its a long shot though

Su Campu

Im getting rightly peed off with the amount of new winter/snow threads that are popping up daily at this stage.

STOP STARTING NEW THREADS WHEN THERE ARE ALREADY FOUR DEALING WITH WINTER / SNOW. :mad:

Any new threads on snow will be deleted as soon as they pop up so please stop wasting your and our time.

Evelyn mentioned earlier on the farming forecast that there could be gusts of up to 70mph (esp in coastal regions) as the tomorrow's cold front pushes over the country. Some very heavy rain forecast as well, esp for the NW but all areas at risk. Could be one to watch.
