| - | NW flow aloft continues on Friday around a mid-summer ridge of high pressure anchored over the Desert Southwest. Expect afternoon temperatures in the low to mid 90s today, with plenty of sunshine expected. |
| - | Slightly drier air will push out of Wyoming today, which will limit the coverage and strength of showers and thunderstorms. The threat for heavy rainfall is low, but with weak steering flow and ample moisture in place, stronger thunderstorms could produce locally-heavy rainfall. |
| - | Today's storms will track slowly to the SE at around 8-13mph, with the best chance for a storm over the District occurring between about 4:00pm-9:00pm. |
WORST CASE SCENARIO: A strong, slow-moving thunderstorm cell produces rainfall up to 1.70" in 60-90 minutes.
A LOOK AHEAD: A Pacific trough of low pressure arrives on Saturday, leading to a good chance for showers and thunderstorms capable of moderate to locally-heavy rainfall. Look for highs around 90, with storms developing by early afternoon and persisting into the mid-evening hours.
