| - | SW flow aloft remains over the Central Rockies Tuesday, ahead of a Pacific trough of low pressure digging into the Great Basin. Daytime temperatures will be similar to Monday’s readings, topping out in the mid 80s by afternoon. |
| - | Enough moisture exists for a few showers and thunderstorms to develop this afternoon and evening, favoring the northern portions of the District. The threat for heavy rainfall is low, but an isolated stronger thunderstorm cannot be ruled out. |
| - | Today's showers and thunderstorms will track to the NE at around 15-20mph, with the best chance for a storm over the District occurring between about 4:00pm-8:00pm. |
WORST CASE SCENARIO: A strong thunderstorm anchored to a convergence boundary results in rainfall up to 1.20" in 45-75 minutes.
A LOOK AHEAD: The mentioned trough swings through the Northern Rockies on Wednesday, which will lead to a slight uptick in shower and thunderstorms across the area, once again favoring northern portions of the District.
