Winter 2019/2020 - General Discussion

-0.2C here but its high ground here in Kilkenny, while I see in Kilkenny city its -2.7C.

Andy From Sligo

-2.9'c currently - south sligo

Danno

Another dive in temperatures, currently -4.3c on the AWS. This seems to be a trend tonight - plateau for an hour and then drop by 1c or so in a few minutes.

The AWS here in south Laois reported -4.2c last night (Mercury thermometer reported -4.5c), so probably safe to say that tonight beats last night as the coldest night of the winter so far. If we breach -4.5c tonight, it will be the coldest night since Ireland's 2018 record low of -9.7c was reported on March 1st that year.

Danno

At 1am it's a chilly -4.8c on the AWS making tonight the coldest since Storm Emma in 2018.

Just for comparison...

A low of -4.7c (AWS) was recorded in 2019
A low of -9.4c (AWS) was recorded in 2018
A low of -5.2c (AWS) was recorded in 2017
A low of -6.7c (AWS) was recorded in 2016
A low of -4.9c (AWS) was recorded in 2015
A low of -5.6c (AWS) was recorded in 2014
A low of -6.1c (AWS) was recorded in April 2013
A low of -5.2c (AWS) was recorded in 2012
A low of -6.6c (AWS) was recorded in 2011
A low of -13.4c (AWS) was recorded in 2010 (Manual was -14.0c)
A low of -7.0c (AWS) was recorded in 2009

-1.0c in West Clare after an earlier low of -1.4c. Strange that Shannon is up to 1°c.

Not a dog owner but a cat owner here Andy and she's in here asleep by the stove since 7 pm this evening.

Just home now, - 4.5 out, and I could hear dogs and possibly cats or foxes around the place. So obviously people do leave them out around here.

Just checked and its actually can back up to - 2

Its a shocking indictment even in this day and age. Is it ignorance , the fact that some people think they have fur and will be ok , or that they are naturally outdoor animals and they will be ok , some people actually thinking its cruel to have them inside , and then some (even though supposed to be family pets) treat them like animals. But then you do get the other end of the spectrum that treat their pets as one of the family ... or sometimes better treated than one of the family!

I agree with you.

The dogs breed determines it's tolerance to temperature. A healthy huskie for example would be fine in -4c

Danno

This is the inverse of watching temperatures on a hot summer day. A little breeze from some direction and it drops/rises dramatically.

Got -4.9c around ten minutes ago, now -3.9c! A gust of 6mph (highest of the day) clearly mixed the airmass a bit!

Nah fecks up the golf in the mornings:mad:

All joking aside with the yellow ball comment.
I had a browse with the effect of frost and a golf course.


I seen this article.

http://dmgcc.blogspot.com wrote:

Frost is basically frozen dew that has crystallized on the grass, making it hard and brittle. A grass blade is actually 90 percent water, therefore it also freezes. Because of the short mowing height (sometimes as low as 1/8 inch) and fragile nature of the turf, putting greens are most affected by frost. Walking on frost-covered greens causes the plant to break and cell walls to rupture, thereby losing its ability to function normally. When the membrane is broken, much like an egg, it cannot be put back together.

Golfers who ignore frost delays will not see immediate damage. The proof generally comes 48-72 hours later as the plant leaves turn brown and die. The result is a thinning of the putting surface and a weakening of the plant. The greens in turn become more susceptible to disease and weeds. While it may not appear to be much of an issue if a foursome begins play early on frost-covered greens, consider the number of footprints that may occur on any given hole by one person is approximately 60. Multiply that by 18 holes with an average of 200 rounds per day and the result is 216,000 footprints on greens in a day or 6,480,000 in a month.

Allenwood Co Kildare this morning

-4C at the moment. The coldest night since before the snow in 2018. I am going for a pre-breakfast walk to enjoy this weather while it lasts.

Just on the pets being left outside, it's not the reported air temperature we should consider but rather the near-ground temperature, as that's where the pet is lying. On clear nights this is several degrees colder again than the air temperature (measured at 1.5 m agl). For example, by 6 am this morning the grass temperature at Oak Park had fallen to -11 °C and at Gurteen -10 °C. The respective minimum air temperatures were -4.1 and -4 0 °C, and they've fallen lower since.

Pressure-wise, Oak Park was the highest at 8 am (1045.1 hPa), with several others on 1044.7.

Despite Waterford being closer to the centre,you're not going to beat Pad's in Naas,which at 100 metres corrected for sea level is already above 1051...

1044 hPa dead bang here and with a fair southerly breeze.

Really anywhere south from a line between Dublin to Shannon (approx) has a fairly reasonable chance of getting a 1048 reading over the next 24hrs. If this figure is achieved at any point then it will be the highest pressure readings for January since 2000.
