Issue Date: 9\/23\/2015
\nIssue Time: 9:08 AM<\/p>\n

A LOW FLOOD THREAT IS FORECAST FOR PORTIONS OF THE SAN JUAN MOUNTAINS, SOUTHWEST SLOPE, SOUTHEAST MOUNTAINS, RATON RIDGE, SOUTHEAST PLAINS, NORTHEAST PLAINS, AND PALMER RIDGE REGIONS.<\/em><\/p>\n

The first day of Fall will bring a second consecutive day of unsettled weather to most of Colorado; the Northwest Slope and Grand Valley regions will be the exceptions, where dry conditions will welcome the official changing of the seasons. Elsewhere, ample moisture and favorable dynamics will allow for isolated<\/span>-to-scattered<\/span> showers and thunderstorms to develop this afternoon and evening, producing mainly light-to-moderate rainfall, gusty winds, and some lightning.<\/p>\n

\"IPW_09232015\"<\/a><\/p>\n

A few storms will be capable of producing heavy rainfall, thanks to the amount of mid-level moisture present from the remnants of tropical disturbance (see IPW chart above) and ample moisture available in the low-levels (surface dewpoints are in the 50s and 60s across eastern Colorado). The locations that are most likely to be impacted by heavy rainfall have been included in the low flood threat area. For more information on rain rates and timing, please see the zone-specific discussions below.<\/p>\n
