Time: 954 AM Wed July 3, 2024 Forecaster: Laura Smith ------------------------- Heavy Precipitation Outlook Flash Flood Prediction Program ------------------------- Hot with isolated afternoon to evening storms. Mostly sunny morning skies will permit afternoon temperatures to climb into the 90s today ahead of an approaching disturbance. This afternoon, an upper-level trough and accompanying cold front will sweep across the High Plains. Dewpoints will be in the low to mid 30s with precipitable water (PWAT) values around 0.50”. These conditions will support chances for isolated showers and thunderstorms during the afternoon and evening, capable of producing light rainfall amounts. Storm motions will be from west to east around 20 mph. More favorable conditions for severe weather will be present just east of the District today. These storms are currently expected to remain east at this time. STORM RAINFALL POTENTIAL AND DURATION: Thunderstorms today have the potential to produce up to 0.10” in 10-30 minutes. WORST CASE SCENARIO: Thunderstorm clusters or complexes may be capable of producing 0.50” or more in 30 minutes or less. A LOOK AHEAD: Dry conditions emerge Thursday as upper-level ridging builds across the Great Basin. Afternoon temperatures will reach the low to mid 80s under clear and sunny skies. Friday will be similar with sunny skies and highs in the low to mid 80s.
