Following an exceptionally mild start to 2013 (averaging 4-5c above the normal mean temperature), the
latest GFS computer model ensemble confirms falling temperatures over
the coming days. The temps shown above refer to the air temperature at 2
metres above ground level in Co Down.
Daytime temperatures are likely to be 2-3 degrees milder in the western half of Ireland. Overnight frosts from tomorrow (Tuesday) night becoming more severe and widespread toward the weekend.
Beyond this weekend, there is a wide scattering of the various model perturbations in relation to our weather. The latest (06am) GEFS output presents somewhat of a mild rather than cold outlier. However, such an outcome is very uncertain at this stage. Image c/o Netweather.tv
