Forecast: Rain Drain

By Matt Rogers

Time to launch the umbrellas again

By Matt Rogers

The umbrellas have gotten quite a workout here in May and the numbers confirm it. Washington Reagan National Airport has reported rain on 11 of the 19 days so far this month. The aggressive precipitation pace has made May 6.4 inches wetter than normal so far. That is quite a soaking. We are looking at two more rain days here today and tomorrow. The other story will be cooler than normal conditions. With morning temperatures expected in the 50s, a jacket might need to accompany the umbrella to work.

Cloudy, cool, rainy. Low to mid 60s. The heaviest rain activity looks to be in the morning and during the midday hours; but showers could still persist into the evening rush. Generally, about 0.5 to 0.75" of rain will fall. Expect cool weather in the morning with 50s and a struggle to reach the expected maximum mid 60s in the city.

Clouds break up late at night and cooler weather resumes. Lows should be in the 40s in the suburbs and near 50 in the city. Cool west to northwest breezes.

Confidence: High

Keep reading for the forecast for tomorrow through the holiday weekend. See NatCast for the forecast for tonight's game.


More clouds. More showers. Upper 60s. Another disturbance will swing through the area on Wednesday, offering the best chance for showers in the afternoon period. This is not expected to be as heavy or persistent as today's weather. Look for temperatures to peak in the upper 60s (still cooler than normal).

Clouds should once again offer a slow retreat and temperatures are expected to reach down to cooler levels in the 40s to near 50.


Thursday and Friday can be paired together as they offer similar weather with sunshine, highs near 70, and lows in the middle 40s to lower 50s. Confidence: Medium-High

The three-day holiday weekend outlook is looking grade-A right now with mostly sunny conditions and highs mainly in the 70s with lows in the 50s. Stay tuned for updates, but for now it looks as though the weekend will escape the May rain drain! Confidence: Medium

Could we *not* have rain for a full week?

I don't know about you, but all the rain has made my garden come alive! Azaleas have grown inches over the last 3 days, my peonies have taken over, and my tomato's are shooting to the sky.

while it might be making my commute a pain, my garden sure is loving it!

By the time this rain is over, summer will be here...

Jamie - yes, the rain has provided some much-needed moisture, but my basil, oregano and cilantro hate the cool weather. they love the steamy stuff, and as such, have halted any upward progress pending warmer weather. i probably planted too early, though.

bring on the sunshine!

Water for gardens = excellent.

Water loosening soil under big trees so they come down (couple weeks ago one fell on my roommate's car and no one's parked near that copse of trees since for fear the others will come down too) = less so.

Sunshine and drying out a bit would be nice....

Jake in Reston is right. We've essentially lost spring this year. Most of the month of May, we've been locked in a more winter-like pattern. Cooler than normal and much wetter than normal.

It's a shame, because I really look forward to spring each year.

Uncle already on the rain! How sure are you at this point that this weekend will be nice? Seems like a long time away...plenty of time for rain to enter the picture given recent weather...

Anyone remember Spring of 03 when EVERY weekend for like 16 weeks it rained? At least this is not THAT bad.

Sudden very heavy downpour accompanied by thunder in Beltsville.

As usual, the weather pattern we WANT in January arrives four months too late; temps, though, seem cooler now than they were even in midwinter...
