| A weak cold front is expected to sweep across the plains overnight, bringing a chance for a few scattered showers across the District during the overnight and into the early morning hours tomorrow. Cool temperatures in the mid 40s and PWAT values of around 0.55 will result in relatively light precipitation during the frontal passage. The best chance for morning showers will be between 3am-7am. Atmospheric moisture will continue increasing tomorrow, with a better chance for full sun will bring better chances for more meaningful precipitation tomorrow afternoon and into tomorrow evening. |
WORST CASE SCENARIO: Stronger showers will have the potential to produce up to 0.25” total rainfall 15-30 minutes.
A LOOK AHEAD: On Sunday, the cut-off low will begin shifting east, supporting better chances for showers and thunderstorms Sunday afternoon and evening. Afternoon temperatures will be in the mid to upper 60s with dewpoints in the upper 30s to low 40s. Storm motions will be from the north around 20 mph helping limit point rainfall amount. However, a stronger storm could produce a gust front with potentially slower storm movements as storms develop off flanking boundaries.
