Snow accumulations of 3-6 inches are possible on Thursday across the Central Rockies with accumulations in excess of 10 inches possible in higher elevations. Heavy rain amounts of 2-3 inches and flash flooding is possible across the Central Plains and Midwest.
An area of low pressure is forecast to continue deepening across the Rockies, with a surface low centered over northwestern New Mexico. With southeasterly to southerly flow from the Gulf of Mexico ahead of the warn front, as well as seasonably warm temperatures, a line of thunderstorms will develop across the Plains and the Midwest as the cold front moves across the region. While widespread severe thunderstorms are not expected, periods of moderate to heavy rain will be possible from Northern Texas to Southern Wisconsin with 2-3 inches possible in most locations. Isolated amounts in excess of 4 inches will be possible in or near the strongest rainbands. Flash flooding will be possible throughout the day.
With the area of low pressure over northwestern New Mexico, cold air will continue to stream southward across portions of the Central Rockies. As lift is provided across the region from the area of low pressure, light to moderate snowfall will develop across the region. Total accumulations of 3-6 inches with locally higher amounts in excess of 8 inches will be possible in higher elevations.
