Time: 942 AM Tue June 25, 2024 Forecaster: Laura Smith ------------------------- Heavy Precipitation Outlook Flash Flood Prediction Program ------------------------- Hot with isolated showers this afternoon and evening. Hot conditions will return today as the heat dome expands again across the Desert Southwest. High temperatures will soar into the mid to upper 90s across the District. Dewpoints will be in the mid to upper 40s with precipitable water (PWAT) values around 0.65”. High-based gusty showers and thunderstorms are expected to develop this afternoon. However, storm coverage is expected to be isolated and therefore less than yesterday. Storm motions will be from west to east around 25 mph. STORM RAINFALL POTENTIAL AND DURATION: Thunderstorms today have the potential to produce up to 0.10” in 10-30 minutes. WORST CASE SCENARIO: Strong thunderstorms may be capable of producing 0.25” 30 minutes or less. A LOOK AHEAD: A more active pattern emerges tomorrow as elevated moisture levels and favorable upper-level winds support chances for scattered thunderstorms during the afternoon and evening. High temperatures will be in the low to mid 90s with dew points around 50°F, supporting better chances for more meaningful precipitation across the District.
