Locking the cold out? Yes please. Why hadn't they thought of this any sooner? It could have saved them from having snow in the Great Hall. It was the most annoying thing when trying to enjoy a meal. Was it any wonder she usually just snacked down in the kitchen these days unless given reason to do otherwise? The Gryffindor was entirely sick of the sight of snow. It'd been enchanting as it was every year until it struck March and the weather gave little indication of letting up. Now it was a nuisance, a haunting one.

Not bothering to take her wand from it's holster yet--save the hands some warmth while she still could--Lex simply sat there bundled in her blanket as she was, ready to get the incantation rolling off her tongue.

"Caelum Saepio...CAY-lum - SAY-pee-oh....CAY.....lum...SAY...pee-oh" Admittedly it wasn't one of the trickier ones that she might have needed some time to get her tongue accustomed to. Almost had a nice ring to it but that might have been because of what it could do and how cold she was feeling right about now.

Clearly her hot air charm was wearing off. "Caelum Saepio."
