9:45 a.m. - Line of intense showers with gusty winds to sweep across area

Radar shows a skinny, but intense convective line forming just west of the Beltway stretching from Warrenton through Sterling into Gaithersburg (as well as to the south and north). This will pass through the immediate area over the next one to two hours producing a brief period of heavy downpours and, in some areas, some strong wind gusts of 30 to 40 mph or so. You might have hear a rumble of thunder.

After the line passes, light rain will continue through midday or early afternoon before gradual clearing begins.

The National Weather Service did cancel the wind advisory but pockets of strong gusts are still possible.

Detailed forecast from 5 a.m.

Today (Thursday): Widespread showers dominate the morning, with a heavy band or two of rain potentially leading to localized flooding. Rain totals for much of the area top out around an inch, with locally heavier amounts possible. Strong south winds (gusting over 40 mph in some showers) pose visibility problems for drivers and umbrella nightmares for walkers.

By afternoon, skies will already be clearing as gusty winds shift to come from the northwest. Highs occur early in the morning in the mid- to upper 50s and are likely to fall to the upper 30s by sunset. Confidence: Medium-High

Northwest winds pick back up, gusting to 20 mph. Highs are mainly in the upper 30s to about 40 downtown. Confidence: Medium-High

Tomorrow night: Mainly clear skies and calming winds allow temperatures to drop quickly. Lows bottom out in the teens in most areas, staying in the low 20s inside the Beltway. Confidence: High

A LOOK AHEAD

Saturday has plenty of sun, but temperatures struggle to recover, with most areas seeing highs only in the low to mid-30s. Winds are light during the day and calm at night. Lows should range through the 20s. Confidence: Medium-High

Temperatures moderate a bit Sunday as the heart of the arctic air pulls north and allows highs to climb into the low to mid-40s. Clouds pop up as the day warms, but sunshine still has the upper hand. Partly cloudy skies continue through the night, with lows in the mid- to upper 20s and low 30s downtown. Confidence: Medium

Monday is partly sunny and a little warmer, with highs mainly in the mid-40s. Confidence: Medium-High
