* Flash flood watch from the District and to the northeast through 3 a.m. *

It’s probably a good idea to bring that umbrella with you tonight if you need to venture outdoors. We’ve got a very unsettled atmosphere, with storms and heavy downpours possible at any time. Think of it like a Florida climate, without the weirdness of Florida. We’ve got one more day of heat and storminess to get through before some pleasant weather develops midweek.

Through Tonight: Scattered thunderstorms and heavy downpours continue past sunset. Heavy rain will be the main hazard, with a chance of some storms becoming severe with strong wind gusts and frequent lightning. Localized flash flooding is possible over areas that get multiple rounds of rain. Most of the action should shift to the east between 8-11 p.m., with some spotty showers or a brief downpour lingering past midnight. Otherwise, mostly cloudy overnight with temperatures in the mid-70s under a light south wind. Some patchy fog possible toward daybreak.

Tomorrow (Monday): One more day of hot, humid and unsettled weather. Generally a mix of sun and clouds with temperatures reaching the low 90s once again under a west wind at 10 mph with slightly lower dew points (60s). We have a 50 percent chance of isolated showers and thunderstorms in the afternoon, though I am thinking the coverage should be less than it was this weekend. Partly cloudy and more comfortable tomorrow night with lows in the mid-70s.

Saturday storm roundup part deux: Julys in the D.C. region are hot, this much we know. We are right around our peak average for the warmest temperatures of the year, which means we are also at our most vulnerable point for daily thunderstorm activity. Several rounds of storms moved through yesterday, with the first batch causing the most wind related damage of the day. After that, it was mostly a heavy rain affair, save for a rogue tornado warning south of Fredericksburg.
