| - | After record breaking heat yesterday, very little change in the forecast today with highs expected in the low to mid 90s this afternoon. Although minimal, a slightly better chance today for scattered high-based afternoon/early evening rain showers/isolated thunderstorms. However, Most areas will likely remain dry today, with any storm development favoring areas along the Palmer Divide and eastward out on the plains. |
| - | Best chance for storm development will begin between 2-4pm with a chance for rain showers/isolated thunderstorms through 7-9pm with a slight chance for continued rain showers favoring northern portions of the District at this time. Most rain showers/isolated thunderstorms will be high-based if they do develop, resulting in a better chance for gusty winds and the occasional lightning strike, however, current dewpoints are in the low to mid 50's for eastern portions of the District. If these dewpoints struggle to mix out during the day, a threat will remain for isolated moderate to heavy rainfall if a stronger storm is able to develop, especially off an outflow boundary resulting in erratic or stationary storm movement. |
| - | Any threat for stronger rain showers/isolated thunderstorms diminishes quickly after sunset with generally mild conditions overnight and into Friday as lows are expected to reach the upper 60's to low 70's for the plains with low to mid 60's along the foothills. |
WORST CASE SCENARIO: A stronger thunderstorm that forms along an outflow boundary will have the potential to produce 1.2" in less than 60 minutes.
A LOOK AHEAD: Monsoonal moisture returns Friday afternoon with a good chance for rain showers/thunderstorms over the District during the afternoon/evening and through the overnight into Saturday. As this disturbance slowly churns, rain and thunderstorm chances will continue over the region through the entire weekend before this disturbance starts to move eastward. With adequate moisture in place at the surface and in the mid to upper-level, the threat for heavy rainfall will likely persist through the weekend before the region starts to dry out on Monday of next week.
