-	High pressure will strengthen over Colorado today with hot temperatures returning to the District. Partly cloudy skies currently will give way to better clearing by early afternoon with highs reaching the low 90s over the plains.
-	Subtropical moisture rotating around the center of high pressure is moving into the District today. The increase in moisture along with daytime heating will result in 1-2 rounds of widely scattered thunderstorms this afternoon. Storms will initially develop over the foothills around midday, before reaching the lower elevations by early/mid afternoon. Storm activity should quickly taper off after sunset this evening with the loss of daytime heating.
-	Storms today are expected to be on the weaker side with most storms producing light to moderate rainfall amounts. However, if a stronger storm manages to develop, then the potential will exist for brief heavy rainfall. Dewpoints today are generally expected to be in the low to mid 40s with storm motions to the E/SE at 10-15mph.

STORM RAINFALL POTENTIAL AND DURATION: Typical weak thunderstorms will produce rainfall amounts of TR-0.25" in 10-30 minutes, with up to 0.6" possible in 10-30 minutes under stronger thunderstorms.

WORST CASE SCENARIO: Training of thunderstorm cells results in rainfall of up to 1.0" in 60 minutes or less.

A LOOK AHEAD: Another hot day is expected on Thursday with a chance of isolated afternoon/evening thunderstorms, though coverage looks more spotty today with storms producing only light rainfall. A rather active pattern for this time of year is then expected from Friday through Sunday as a series of upper level troughs containing subtropical moisture move across the Rockies. Cooler temperatures along with a good chance of thunderstorms can be expected each day Friday-Sunday with heavy rainfall possible.
