The weather tower aglow in yesterday's sunrise, with a few remnants of rime ice hanging on before they were gobbled up by today's warm, wet fog. Behind the tower off to the west you can see the shadow of Mount Washington, cast by the rising sun.

The summit burst out of the fog this morning and was treated to pretty spectacular snowliage! Temperatures will rise well above freezing tomorrow, however, melting much of the rime ice we've been able to accumulate over the past several days.

Though Nimbus doesn't venture outside as often to join us on our weather observations now that the summit's frosty again, he still enjoys lounging in the sunshine by the beanbag chairs on a chilly autumn day!
