The last thing I need is some stupid half-inch rainstrom screwing it up at the end. Drought records are one of the very few extreme events I would say no to, even though it doesn't affect me personally much in the end. I wouldn't mind a driest month record if we weren't already in drought conditions, but there's no reason to make the bad worse. It looks like most areas could expect around a half inch of rain this weekend, give or take. Link to comment Share on other sites More sharing options...

WinterWxLuvr Posted April 19, 2012 Share Posted April 19, 2012 What is the latest Euro showing for this? I can't access those maps here at work. Also, does anyone know why on the Wundermap site, several of the things listed at the right have a strike through over them, including the one labeled models? Is this a computer setting that I can change? Link to comment Share on other sites More sharing options...

Also, does anyone know why on the Wundermap site, several of the things listed at the right have a strike through over them, including the one labeled models? Is this a computer setting that I can change? euro still had like 1"+ i95 and east.. a little less particularly west than prior runs. in this situation i might be tempted to believe the GFS scenario tho it looks like it brings the coastal precip in a little closer this past run. however we suck at getting a phase right to get good precip so i'd lean toward the lighter end. why anyone was talking about widespread 'drought busting' rains is beyond me tho. perhaps im wrong but i don't really believe in heavy rain with a frontal passage and i think we're going to need help with the coastal.

Agreed... also, to add on, we'd probably need a couple 2-3" rain events to alleviate our drought, maybe more on Delmarva. Link to comment Share on other sites More sharing options...

Most of the drought busting comments are probably based on the runs from a couple of days ago that had the low running up the coastal plan or even further inland. Now it looks quite mundane.

Now it looks quite mundane. yeah probably.. and i guess i was specifically thinking of local JB -- as recently as yesterday -- talking about widespread 3"+ amounts across the area. the models are generally iffy with stream interactions that become high qpf events, and of course we've seen that play out a number of times over winter etc. it pays to remain skeptical in these situations i think... and re: mark, yeah, could be we need a few rains. though at least in this area we can 'bust' it fairly quick maybe not as much so to the east. personally i hope we lock into an east coast ridge pattern with a west coast trough in the next few weeks.

Its forecast suggest to keep and open mind about Sunday. Ensemble mean has about 1.25" of precip for DC. The low is a bit more east then the euro at your location but curls back into and thru NYC later on. The spread has decreased because the low looks more consolidated then previous runs.

So, on average, summer precipitation in those ten years has been 1.14 inches above the long-term summer average, but with the yearly average for those ten years 3.7 inches below the long-term yearly average.

So, on average, summer precipitation in those ten years has been 1.14 inches above the long-term summer average, but with the yearly average for those ten years 3.7 inches below the long-term yearly average. One more note on this: Precipitation for the ten lowest years in DC during January through April has averaged 7.49 inches, versus an average of 12.60 inches during those four months, 1871-2011. So, there was an average precipitation deficit during those years in the first four months of 5.11 inches. Therefore, with a corresponding yearly deficit of 3.7 inches, there was a precipitation surplus over the final eight months for those years of 1.41 inches, of which 1.14 inches came during June, July, and August. So, on average, when there has been an exceptionally dry January through April in DC, a portion of the precipitation deficit has been made up during the summer, with the other five months of the year featuring nearly average precipitation.
