| Sufficient moisture and a small disturbance will provide forcing for afternoon thunderstorms today. Afternoon temperatures will be in the low 90s, dewpoints in around 40°F, with precipitable water (PWAT) values around 0.70”. Today's storms will be high-based and relatively fast-moving. Widespread convective initiation will begin over the mountains and foothills around lunchtime, but the storms that reach the urban corridor are likely to be isolated and subject to evaporative cooling processes that make measurable precipitation scarce. Storms that do spill off the mountains will do so between 2PM-10PM, clearing out overnight and leaving behind clear skies. |
WORST CASE SCENARIO: Strong thunderstorms may be capable of producing 0.25” 30 minutes or less.
A LOOK AHEAD: The following days will all look like today as the ridge settles in, with daily highs climbing into the mid to upper 90s. Mostly sunny and dry conditions are expected through the weekend.
