Storms have started to initiate along the foothills and are expected to start moving into the District over the next hour. Like yesterday, slow moving, gust-front driven storms are expected to propagate from west to east around 15-20 mph. However, gust fronts will likely result in additional, slower-moving thunderstorms which will have the potential for moderate to heavy rainfall. Heavy Rainfall is most likely to occur until 9:30 PM tonight. A few lingering showers may persist later through the evening and overnight ahead of the cold front. At this time, the approaching cold front is expected to move through the District early tomorrow morning. There is still some uncertainty about the timing of the front, which will depend on how long the cool airmass stalls north of the Cheyenne Ridge. We will continue to monitor this system as it tracks south and update as needed. |
WORST CASE SCENARIO: A slow-moving thunderstorm or a large thunderstorm complex may result in up to 1.80” of rain in 45-60 minutes.
