PM Update: Showers, some thunder, into tonight

By Ian Livingston

Midweek chill before late-week warmth

* Tornado Alley: What's that??? | Radar & more: Weather Wall *

A few showers this morning gave way to a midday break in the action, but more showers and thundershowers have formed this afternoon and evening. Some severe thunderstorms have been reported south and southeast (including large hail and a waterspout reported in vicinity of St. Mary's county) of the District and may continue affecting those areas through 8 p.m. Otherwise, clouds and the pesky marine air that pushed back south across the area last evening have held temperatures in the low-to-mid 60s.

Monitor severe warnings issued by the National Weather Service and radar on our Severe Weather Tracking Station below. Also, comment below with conditions where you are.

Warning Text: DC | MD | VA * New: Lightning Map
Radar: Latest D.C. area radar loop shows movement of precipitation over past three hours. Powered by HAMweather. Refresh page to update. Click here to see radar bigger.
LWX Warnings
Warnings: Severe alerts from National Weather Service. Updates w/o refresh (most browsers). Hint: Alert on map? Click matching label in key for details.

Through Tonight: An area of showers and storms will cross the area from west to east between now and around 6 to 8 p.m. A few storms may be strong to even severe south of the region, but will probably lose some punch as the sun sets. Though the shower risk continues into the night, it should slowly wane after midnight. We'll probably hold onto clouds through the morning though, so temperatures won't plummet. Lows should fall to the upper 40s to around 50.

Tomorrow (Tuesday): On the backside of the low-pressure system that has recently plagued the area, we'll be treated to a chilly and breezy late-April day. There could be an isolated early morning shower, but otherwise we'll see clearing skies throughout the day. Highs rise to around 60 or into the lower 60s. Northwest winds around 15 mph with higher gusts.

Long-track tornado: The supercell responsible for the Mississippi tornado deaths began in Louisiana and traveled all the way to Alabama over the course of several hours. During this time it spawned a tornado responsible for killing at least 10 people. The NWS office in Jackson, Miss., announced last night that this one tornado was on the ground for at least 97 miles (likely more) and had damage as high as EF4 on a 0-5 scale (5 being the highest). The tornado also had a maximum width of 1.75 miles!

Some thunder this afternoon rolled through with some showers. Last night's intense storms passed a little to the north but could see the flashes. Looks like we've got about an inch over the last couple days.

Last Friday, the trillium looked to be near peak. I think I'm finally ready to let go of any more chances for snow this season...

Thunder & pouring rain in Manassas VA.

wow, spgass1 - you've gotten an inch of rain recently? That's definitely a decent amount. Has anyone else received an inch of rain?.. FIREDRAGON47 - keep us posted on your totals from the downpours today too.

I definately came close to an inch last night. Several rounds of downpours over about a 2 hour span. BWI reported a little over 9/10s of an inch and got the same parts of the storms.

It's sort of funny how DC got mostly missed to the north last night and to the south today...

Measurement is unofficial using a bucket but I just measured 1 1/18th"

I guess it's possible it could be inflated due to bouncing raindrops off a nearby deck railing.

Precip appears to be offline for the closest Wunderground stations to me for some reason today. A station a bit farther away is showing .64"

meant 1/8th in my post above (typed 1/18th)

Rain: In Jefferson County, seems like it hasn't truly stopped since it began with all those storms last evening. The driest we've seen is a heavy mist. (I'm near the Potomac; air might be drier farther out.) The bucket measurement is 2.25".

Evidently the tornado-producing cell responsible for the warnings has produced at least one waterspout on Chesapeake Bay ["Chesapeake Alley" is back in business!].

Got 0.9 today SW of Front Royal and getting more now. We dodged rain showers, some briefly heavy while moving some folks from mid Warren county to Howellsville. Nice spot between the Shenandoah and the Blue Ridge and a bit out of the way if you like that kind of thing (the water was about a foot below the low water bridge).

Though the track has shifted .. yet another one of these big slow closed upper level lows causing a few days of precip. If we still see them heading into the heart of spring storm season around here there should be several interesting severe weather days.

Posted by: Ian-CapitalWeatherGang | April 26, 2010 8:52 PM | Report abuse

Between all the downpours since midnight last night, we've received about an inch of rain. It's still coming down at moderate rate.
