PM Update: Stormy Pattern on the Way Out

By Ian Livingston

Mostly sunny and warmer on Thursday

* Weather & Environment | Climate Chat | NatCast | UnitedCast *

Many places have seen showers or thundershowers containing small hail this morning into the afternoon, largely thanks to a cold pool of air passing overhead. Temperatures have been in the chilly 40s during rainfall, though many places have seen highs rise into the mid-and-upper 50s at some point in the day. Everything is beginning to shift east now, but some additional showers and thundershowers will be possible into the evening.

Tonight: We'll start mostly cloudy with the risk of an isolated shower and finish with clearing skies as well as chilly temperatures. Lows should near the mid-30s in colder locations to around 40 in D.C.

Tomorrow (Thursday): We break free from the cloudy and rainy pattern of the past few days and get on a track that will bring us toward summer-like conditions this weekend. Highs should rise into the mid-60s just about everywhere. It will be a pretty nice day, though a west wind gusting as high as 30 mph may bring a slight chill to the air.

Weather and Sports: After a 22-4 loss to the Indians, Yankees fans may have wondered if their new stadium was cursed. Now, some experts are saying it may be more about how wind reacts with the structure. Did the 8 home runs in that game get a breezy boost? Since then, the stadium has continued to produce high numbers of home runs. Fans and engineers alike will surely be watching to see if the weather is indeed playing a game of its own.

It's been a weird weather day. Sunlight, followed by dark stormy clouds. I went out at lunch it was cloudy; walked back with sunlight and rain. Some people were reporting hail this morning. Not me, but that would have made it a surreal day if I had seen some. jo in NE DC.

I'm going to post this on this thread, since it got started so soon after I posted on the last thread. Plus it relates to the first post. Here it is:

I'm really interested in how much sun I've seen in the past couple days right along with storms. Even when it was hailing and raining this morning on my drive, there would be holes in the clouds that revealed blue sky. Now it's beautiful and sunny out there, but there are more big fat clouds coming in. And last night around 9:30 there were these big clouds and then super starry patches all over.

Why are the clouds like this with this system? What's going on?

The HRs at Yankee Stadium probably have something to do with the home team's atrocious pitching, too.

We just experienced a heavy downpour lasting about 15 minutes. Embedded in the raindrops was wet snow.

The 12z GFS brings the area close to 90 or above both Sunday and Monday.

The higher elevations of West Virginia have been getting snow showers on and off all day. 2 inches was reported at Canaan Valley at 1pm. They might get some more tonight!

90, nooooo, not until I have the air conditioning unit repaired!

NWS says 85 for my neck of the woods on the weekend. I can live with that, and it will fall back to 80 during the week.

Sun came out after a 15 second rainfall.

Laura... We have a typical April moist unstable air setup with plenty of cold air above us and the sun heating some relatively moist air at the surface. Thus we're getting plenty of towering cumulus [congestus] and cumulonimbus clouds, rain, hail and a few thunderstorms.

What interests me is how long this all will last. Will we still see a shower or two tomorrow before the pool of cold air moves out? Showers today extended as far west as Chicago.

We're actually overdue for an extended warm spell in the eighties or higher. Will it dry up? I suspect that because I have dances scheduled Friday night, Monday night and Tuesday night, the anti-Bombo rain conspiracy will have 8 PM thunderstorms scheduled those three evenings when I'm trying to get to the bus stop. Weather charts do seem to indicate a few showers over parts of the Appalachians so such thundershowers certainly aren't out of the question. All they need to do is drift into Chantilly and parts east.

Also, re Yankee Stadium: Fausto Carmona was pitching for the Indians on Saturday and actually LOWERED his earned run average. Most of the homers hit that day were hit by Cleveland.

It should make for an interesting series the next time the bitter rival RED SOX visit New York. Those dates, by the way, are May 4-5, Aug. 6-9 and Sept. 25-27. The Red Sox sure handled the Orioles last weekend.

It will be interesting to see if balls fly out of Yankee Stadium when the wind blows from a different direction.
