- Mixed messages in the clouds: peaceful scene with roll cloud
- W970443S
- Mixed messages in the clouds. Diminishing storms to the east have left an expansive anvil cloud in the sky at sunset. As the sun sinks, its last rays scrape across the sheet’s uneven surface creating a mottled golden pattern of mamma and shadows. The scene was peaceful until suddenly a strong wind brought in cool, damp air from faraway rain. This outflow boundary raced toward the sunset, building a thickening sausage-like roll cloud along the leading edge where enough lift was present to allow condensation. The air mass is stable and cooling so these clouds will remain flat and benign, and will evaporate away as soon as the wind push abates or the moisture mixes out by dilution.
