Risk Of Heavy Snow Showers As It Turns Extremely Cold Sunday Night/Monday

ninebeanrows

Monday looks extremely cold for March, maxima just 1 or 2c in the east. Heavy snow showers overnight Sunday and early Monday is the offering at the moment. Likely accums ~ 10-15c

Yes a surprisingly sweet little upgrade. Better depth and length of cold. A tighter squeeze on the snow machine :pac:

Probably wouldn't get paid if he or she takes a day off.

Definitely a chance of some beefy snow showers Monday, temps might not even go over 1 C in the East so very notable for March! Dew points across Ireland will probably be the lowest we've seen all winter

How about south/south east ?

Its been said a few times that it looks like a decent chance of snow for the east coast . Exactly how much and where is all to play for still. Wont be good to say until at least Saturday night when the hi res models come into range.

I smell ThunderSnow for east coast regions

500 mb temps are cold enough.



Theta - e 850hpa is well cold enough.



Temps at 850hpa -12ºC over Irish sea and sea temps around 8ºC so a difference of about 20ºC. Enough for explosive convection.



Dew points are never going to be a problem in this kind of set up.




So get these charts in a 24-48 hr time frame and the scene is set for a pure whiteout with poor visibility in fresh wind.

Game on for now.

So feckin hard not to get excited about this... yet at the same time be mindful of how many times we were almost there this winter! If this one is to fail, it really will be winter's goodbye and 'up yours' to a lot of people here dreaming for some snow!

If it happens though it sounds just right - a couple of days heavy snow followed by decent cold. Not enough to cause too much disruption but enough for us to enjoy before Spring/Summer kicking in... hopefully.

The Roller Coaster is well and truly on.

YEP! Mentioned it there the other day , it could be interesting indeed once the wind direction plays ball!

I'll be prepping my camera gear if anyone is wanting to head chase some action Sunday monday let me know! :D:D

No it's not a roller coaster,
It's the EVOLUTION.:D

It would be nice to see this, big time ramp

Loving the direction of that isobar thingmajig. Direct line to my neck of the woods via the longest sea fetch possible from Cumbria. IOM shadow?? You're Meath/Louths problem this time buddy!!!

Redsunset

Don't forget that the wind direction is different to the isobars. Slight north east angle.

Rougies

Going by current GFS, the winds (both surface and 850s) will be almost straight easterlies as the cold uppers (-8 and lower) reach our shores at about midday on Sunday gradually turning NE midday Monday to pure northery midday Tues as the colder uppers leave us.

Regarding the IOM shadow, if it does come into effect it will gradually move its way down the coast throughout the 48hr snow window of opportunity.

So hopefully most areas away from the W/NW will get in on the action if convection kicks off early and the Irish Sea plays ball for the duration

Wicklow Weather

Guys I am working out the windchill for Monday afternoon. GFS giving NE wind at between 15 to 25 knots coupled with GFS temps for the same period of approx 0c gives me a windchill of -7c to -10c for Eastern counties. Does anyone know of a Winchill Forecasting site that is accurate?

12z looks sweet so far.

I'd consider the 12z an bit of an upgrade so far, starting to get a li'l bit excited...

Yeah looks a powerful flow off the sea coinciding with the coldest uppers which are hanging around longer too.

Redsunset

Wonderful upgrade. Cold is advected higher and thus lasts longer.The Blizzards are coming. Hope I haven't jinxed this now. Come on Ecm, continue the evolution.

Some folks will be shocked come Monday.

Ok here is what I see,

During Sunday evening very cold uppers move in across the country giving heavy snow to coastal areas of the East and Southeast. Some of these will drift across to luckier inland spots. In general lying snow is confined to the coastal margings (though interestingly coincides with higly populated areas such as Dublin Waterford and Cork) Monday should get further heavy snow showers in these areas and it remains bitterly cold throughout with wideapread icy roads come Monday night. Tuesday it thaws and it's just dry and cold for rest of week.

So as I said last night it's a blink if you miss it affair but should provide quite snowy picture for some on Monday
For me I would prefer a less severe blast that would last we week but then in this country you take what you can get!

Redsunset

You just can't please them all I guess. Roll on the short sharp blast WHOO HOO
