About Winter comes to Nargothrond: What about using it later as an entity? Like this:

But Túrin passed away on the northward road, and Glaurung laughed once more, for he had accomplished the errand of his Master. Then he turned to his own pleasure, and sent forth his blast, and burned all about him. But all the Orcs that were busy in the sack he routed forth, and drove them away, and denied them their plunder even to the last thing of worth. The bridge then he broke down and cast into the foam of Narog; and being thus secure he gathered all the hoard and riches of Felagund and heaped them, and lay upon them in the innermost hall, and rested a while.NA-EX-58.15 <Lay Endnote

Winter comes to Nargothrond
The summer slowly __ in the sad forest
waned and faded. __ In the west arose
winds that wandered __ over warring seas.
Leaves were loosened __ from labouring boughs:
fallow-gold they fell, __ and the feet buried 5
of trees standing __ tall and naked,
rustling restlessly __ down roofless aisles,
shifting and drifting.

__ __ __ __ __ __ __ The shining vessel
of the sailing moon __ with slender mast,
with shrouds shapen __ of shimmering flame, 10
uprose ruddy __ on the rim of Evening
by the misty wharves __ on the margin of the world.
With winding horns __ winter hunted
in the weeping woods, __ wild and ruthless;
sleet came slashing, __ and slanting hail 15
from glowering heaven __ grey and sunless,
whistling whiplash __ whirled by tempest.
The floods were freed __ and fallow waters
sweeping seaward, __ swollen, angry,
filled with flotsam, __ foaming, turbid, 20
passed in tumult. __ The tempest died.
Frost descended __ from far mountains
steel-cold and still. __ Stony-glinting
icehung evening __ was opened wide,
a dome of crystal __ over deep silence, 25
over windless wastes __ and woods standing
as frozen phantoms __ under flickering stars.>

And Túrin hastened along the ways to the north, through the lands now desolate between Narog and {Teiglin}[Taeglin], and the Fell Winter came down to meet him; for in that year snow fell ere autumn was passed, and spring came late and cold. Ever it seemed to him as he went that he heard the cries of Finduilas, calling his name by wood and hill, and great was his anguish; but his heart being hot with the lies of Glaurung, and seeing ever in his mind the Orcs burning the house of Húrin or putting Morwen and Niënor to torment, he held on his way, and turned never aside.>
The Return of Túrin to Dor-lómin
At last worn by haste ...

Thus we have some repeating of simelar lines but I think they can bear it.
