Worrying about the weather will not change the outcome one jot.
Last year, pollen going in up to Christmas Eve, quiet for about 7 weeks and flying strongly, day after day, from at least middle of February and taking in lots of pollen.
Surprise, surprise, not the same this year. Much less pollen available, much less flying time, much colder. Everything much later.
It seems to me to be 'heft and feed if necessary' until a liquid feed can be safely administered by those who want to be ready and waiting for the first heavy flow, and then 'comb capping scratching' to encourage clearing of stores from the brood area (for those who have fed fondant unecessarily), unless one has some spare drawn combs available (unlikely for the beginners).
Standard Nationals on just the brood will be running light on stores shortly (if not already), 14 x 12s and 'standard plus a super' may be a different matter. Topography, location, strain and colony strength might also make a big difference to this year's timetable for action, so every colony can be in a different condition at this present time. So don't take anything written, as 'you must follow'.
Survival of the bees is number one priority. If not experienced, leave alone (apart from feeding fondant) is my advice - until the weather shows definite signs of easing from this wintry period. Could be another month, who knows.
