-	SW flow aloft continues today resulting in hot and mostly dry conditions across the District with high temperatures in the upper 80's to mid 90's this afternoon.
-	Generally dry conditions today as dew points drop to around 30 today. A disturbance will move through around noon, bringing a chance for scattered high-based rain showers/isolated thunderstorms this afternoon and early evening. Storms today will likely produce gusty winds, some lightning and minimal rainfall.
-	Skies will start to clear by sunset as overnight lows expected to drop into the upper 50's to low 60's.

STORM RAINFALL POTENTIAL AND DURATION: Weak thunderstorms will produce a trace to 0.1" in 10-30 minutes. A moderate thunderstorm could produce 0.1-0.2" in 10-30 minutes.

WORST CASE SCENARIO: A slow moving moderate thunderstorm, or stationary storm from an outflow boundary could produce 0.2-0.5" in 30-60 minutes.

A LOOK AHEAD: An active weather pattern heading into the weekend with a good chance for afternoon and evening rain showers and thunderstorms Friday, Saturday and Sunday. Best chances for heavy rain will be Friday and Saturday as storm motions slow down along with an increase in surface moisture. High temperatures will remain in the upper 80's to low 90's through the weekend.
