CommuteCast: A Soggy Ride Home

By Ian Livingston

Low pressure loosens grip tonight into Tuesday

Heavy showers and some isolated thunderstorms have continued across most of the area today, if at lesser intensity than yesterday. Two-day rainfall totals have now pushed near or over 4" at some reporting stations, like Dulles Airport, and many rain buckets will fill up a little more before it all comes to an end. A concentrated area of activity is now targeting the region, and it will move through during the rest of the afternoon. Expect periods of moderate to occasionally heavy rain with this batch as ponding of water continues on area roadways.

Tonight: We will see the beginning of the end for this storm across the area overnight. Expect showers to become less numerous as the night wears on, and by morning most of the region should be just cloudy with areas of drizzle or light rain. Low temperatures will be in the mid 50s as continued high levels of moisture in the air keep temperatures from falling too much.

Tomorrow: Tuesday will be much drier than the last two days. Even so, the storm system will continue to affect our weather by funneling northeasterly winds into the area off the Atlantic Ocean. This will allow us to remain under a marine air mass, with cloudy skies and occasional drizzle or light showers. Some breaks in the cloudiness may appear late in the day, especially west of D.C., as temperatures rise only into the low 60s for daytime highs.

My total rainfall since the inception late Sat. stands at 1.17. The "training", east of the mts. would have been more than welcome in this area. The more east to west component to the movement today has moved showers back into my area, but yesterday we had no rain with a good deal of sun!

How does all this rain effect the drought in this area ? Are we out of the woods yet ?

2.86" so far here. A little blue sky visible now.

Seems most of the convective activity got squashed in the region on its way in. Perhaps the atmosphere is too stable after the past 36 hours?

Rain appears to be over in NW Montgomery. Seneca Creek never quite got out of its banks. 3.11 inches at my place which is the most rain in one event since September, 2003.

The sun shone through some clouds about two hours ago, for a few minutes. I'm hoping the sun will really come out tomorrow.

Accotink Lake/Mixing Bowl/West Springfield = 4.02" storm total as of 7:00pm 4/21/2008.

All I can say is, it is WET out there! Neat that we broke 4 inches.

Many are out of the "woods" "short term".

The question of "Drought" is for the long term.

We need normal to above normal precip. throughout the summer to maintain adequate soil moisture for most, because of the drier than normal last 12 months.

Hi Jenn -- Good question ... the Post had a story on exactly this earlier today.

Confirmed tornado touchdown in Frederick, VA last night. I remember watching Fox 5 and they were talking about the rotation in this storm right before the tornado warning was issued.

That wind out there is mighty pleasant... slightly more brisk and less moisture-laden than previous days. Hey, when looking for a "nice" night... I am not picky right now! ;)
