Record maxima and minima for each date in January
It however seems even less likely that any new records will be set for maximum temperatures in January, though I suppose 24th (14.4 deg. C. in 1937 and 1962) and 25th (13.9 deg. C. in 1997) are possible.
Castlederg is in West Tyrone and has often had the highest summer temperatures in Northern Ireland (e.g. the highest for the year in August 2002, August 2003, July 2006 jointly with Peatlands Park in Co. Armagh, June 2007 & July 2008) but also can record quite low temperatures (for Northern Ireland). There are, or were, at least a couple of weather stations somewhat west of it (Corgary and Cross Hill) and it is possible that it was one of these rather than Castlederg which recorded the very low temperature in December 1995, but on the whole I would plump for Castlederg.

This is another temperature record which seems to have gone unreported for some years, though this is a joint record, and was not unreported for nearly as long as the 25.6 deg. C. on 29th March 1968 at Mepal in Cambridgeshire, which overtook the previous record of 25.0 deg. C. on the same date at both Cromer and Santon Downham in Norfolk, along with less satisfactory records of 25.0 deg. C. at Wakefield in Yorkshire in March 1929 and 1965 and Whitby also in Yorkshire also in March 1965 - see http://www.personal....er_in_march.htm and http://www.metoffice...minimum_england
