| - | Brisk SW flow aloft continues over Colorado Wednesday, as a strong trough of low pressure tracks into the Northern Rockies. Daytime temperatures will be slightly cooler today, with highs in the low to mid 80s under partly-cloudy skies. |
| - | Lift from the approaching trough will help trigger a round of showers and thunderstorms this afternoon and evening. Similar to Tuesday, the majority of showers and storms should stay just N of the District. |
| - | The threat for heavy rainfall is low, but an isolated stronger thunderstorm could produce moderate to briefly-heavy rainfall. Today's storms will track briskly to the NE at around 20-25mph, with the best chance for a storm over the District occurring between about 3:00pm-8:00pm. |
WORST CASE SCENARIO: Training of strong storm cells over the same area results in rainfall up to 1.20" in 45-75 minutes.
A LOOK AHEAD: A cool and dry airmass arrives Thursday behind a cold front, with highs only in the mid to upper 70s and plenty of sunshine. Precipitation is not expected.
