wind vs snow

At the sight my scrambled brain congealed. I drew up my will, flung out a hand, and screamed, "Ventas servitas!"
Wind roared forth from my outstretched fingers. I directed it at the snow-covered ground in front of our attackers, and a sudden storm of flying bits of ice and snow engulfed the gunmen.
I kept the pressure on them, maintaining the spell, as I shouted, "Molly! Get to Murphy! Veil and first aid!"
Molly shook her head and gave me a glassy-eyed stare, but she climbed out of the car and staggered over to Murphy. A second later both of them vanished from sight.
I let up on the wind spell. Moving enough air to keep a gale-force wind going is a lot more work than anyone thinks. The air went still again except for swirling eddies of wind, frost devils that danced about in half a dozen whirling helices of snow. The two gunmen were revealed, crouching low, their arms still upraised to shield their eyes from the wind and stinging flakes of ice.
