A slight shift in the upper-level flow aloft today will bring more westerly flow aloft over the region today as high-pressure continues to churn over the desert southwest. Mild and dry conditions are expected throughout most of the day today under mostly sunny skies. Another very slight chance this afternoon for a few high-based showers and possibly a thunderstorm or two. Most storm activity will remain anchored to the foothills, likely mixing out as they move eastward and onto the plains. Once again, the majority of, if not all precipitation will struggle to reach the surface, resulting in gusty sprinkles rather than any meaningful rainfall within the District. The best chance for storm activity will be from 2-8pm with skies starting to clear by sundown. Overnight temperatures will drop into the upper 50s to around 60 degrees on the plains with mid to upper 50s along the foothills. |
WORST CASE SCENARIO: A moderate to strong shower/isolated thunderstorm will have the potential to produce 0.10”-0.30” total in 10-30 minutes.
A LOOK AHEAD: Westerly upper-level flow aloft continues bringing another mostly mild and dry day tomorrow as high temperatures reach the upper 80s to around 90 degrees. Another slight chance for a few high-based showers and possibly a weak thunderstorm or two, mainly along the higher terrain foothills and Palmer Divide. A relatively weak disturbance will move into the region Wednesday, bringing a slightly better chance for afternoon showers and thunderstorms with minimal chances for any heavy rainfall at this time.
