Take it easy there owen, you'll give yorself a heart attack!
Some really beefy hail showers going to be around from tomorrow, should see some thunderstorms in the northwest and west. There is a chance that in these showers some of the snow from upper levels will get blown downwards by some downdrafts giving some brief flurries at maybe 150-200m, but it won't hang around for long.
There should be some nice photo opportunities so always have a camera at hand!
And then of course there's the GFS taunting us with the polar low scenario again Saturday, but we're not going to be fooled again! :rolleyes:

I would have to disagree with your altitude estimates for snow, i expect snow to get to low levels during the week and quite frequently.
Lots of nice charts tonight keeping the cold with us for the forseable future.0 -

???????????????????? Hi WC, where is your optimism for snow coming from ?
All I can see for the week ahead is temps being slightly colder than normal with rain and the odd hail shower at lower levels.
I don't understand where all this talk of snow is coming from!

we are in clear spell mode now and temp has dropped to 0.5c hopefully we can stay like this for a wee while to get to say -1c and then the showers can come on in.. should i expect any lying snow in the mornig?
No, don't expect any snow
Any precipitation in Coleraine will most likely be of rain ...no pun intended

I dunno, I go by the 850hPa wet bulb and theta potential temperatures. The lowest WBPT forecast this week by both GFS and NAE is +2°C, which equates to a snowline of around 250m. Similarly the lowest thetas of around +13°C show 200-250m.
We need WBPT of -1°C and theta of +8°C to be 100% guaranteed snow at sea level. There is a hint that these may lower near the weekend, but until Friday I don't see any snow at low levels.

The main markers i use for potential snowfall are dewpoints, 850hpa temps and 850-1000hpa thicknesses.
No denying the marginality of the week but with 850-1000hpa thicknesses flirting towards 129-130, 850hpas around -5c and some -1c - 2c dewpoints. I would expect with decent precip wintry precip and snow to reach low levels rather regularly.0 -

Voice of reason once again
I am starting to believe that there are some posters on this forum who think if they believe hard enough, then snow will arrive!
Just watched the weather after the Nine news - daytime temps of +3oC to +7oC over the coming days; it just does not snow with such high temperatures...:rolleyes:

You seem to be missing a point with temperature maxes though.
Its mid February the sun is getting higher, with sunny breaks during the weak temperatures could push up to 4/5c and perhaps 6/7c in the south and southwest. However dewpoints will be around 0c and when precipitation/ cloud cover arrives temperatures would drop quickly back to 1-3c and 0c/-1c dewpoints.
Its easy to look at the max and say no chance but you would be wrong.0 -

yes it does because the majoeity will be 3-5c and the far south will only reach 7c and for proof it can snow above 3c today it snowed ay 4c0 -

During any other winter we'd be ramping up!
