-	A trough of low pressure will track south of the District today, while at the surface easterly upslope winds will develop leading to increasing low level moisture this afternoon. Highs today will be near seasonal values in the upper 70s to low 80s on the plains.
-	Instability will be weaker today across the District compared to recent days. This should delay thunderstorm activity across the lower elevations of the District until late afternoon and early evening, while terrain-driven thunderstorms over the foothills and Palmer Divide should develop by early to mid afternoon.
-	Storm coverage will be more spotty today compared to recent days, but storm motions will be slow and erratic, which could result in storms becoming nearly stationary over an area. If moderate to strong thunderstorms manage to develop, the potential will exist for heavy rainfall with dewpoints ranging from the mid 40s to near 50, and precipitable water values of around 0.75-0.8". Thunderstorms could linger well into the evening before tapering off overnight.

STORM RAINFALL POTENTIAL AND DURATION: Typical weak to moderate thunderstorms will produce rainfall amounts of 0.1-0.4" in 10-30 minutes. Strong thunderstorms will be capable of producing rainfall of 0.4-1.0" in 10-30 minutes.

WORST CASE SCENARIO: A strong thunderstorm stalls over an area, resulting in heavy rainfall of up to 2.25" in 1-2 hours.

A LOOK AHEAD: Low pressure will move east of the area on Thursday, but enough lingering moisture will result in isolated to widely scattered thunderstorms Thursday and Friday with moderate to heavy rain possible under any stronger storms. Highs near 80 on Thursday on the plains, warming up into the low/mid 80s on Friday. A trough of low pressure will move across the Northern Rockies late Saturday and a strong cold front will move through the District Saturday evening, resulting in a chance of evening showers and thunderstorms with some potential for heavy rainfall depending on the exact timing of the front.
