Lol, we must have gotten under the same cloud :) Of course, it took 3 days to give me my .95 :) Last night felt great, with the fan off, and the blanket on, but it is already warmish this morning. Hope Robert's cut off appears next week. T

I think we're still game on with the baggy trough or cutoff. There's an outside chance though that it never stalls and instead moves east and minors out across the Carolinas Sunday or Monday. Right now it looks like this will be a very big deal for Texas and Louisiana and possibly all the way to the Florida panhandle. Look how strong the vorticity is still with the system coming into Texas. It should begin to slow down some tomorrow and Saturday , but I think it maintains its structure pretty well, but will feel the effects of the northeast trough (this will slow it down around Alabama--maybe completely stall out). So its tricky what happens beyond Sunday, but if it slows, that will benefit Georgia even more, putting your area under good lift and moisture. Most of the precip events this Spring have been way too progressive in Georgia and the Carolinas, this one actually looks like the opposite, which is why I'm pretty excited for atleast Georgia and north Florida's shot at very good rains soon. Leary about the Carolinas' totals on this one since it would have to stall almost perfectly to get this area sustained showers and storms. But for Alabama (and probably west half of GA) and points west, it looks like a very good period of rain showers and storms on the daily, for about 5 days. There's another Rockies trough that actually may help keep the Deep South system around, by pulling it back toward the west next week, or keeping it stalled (whats left of it will just be a weak mid level cutoff by then). But in May, all we need is a weakeness aloft, ample moisture (high dewpoints) and no capping, good Gulf inflow and weak disturbances. We'll have all that beginning soon, the big question to me is can the Lakes trough Monday drop south enough to pull the southern system out to sea quickly, or will it leave part of the spin behind. I think it leaves part of the spin behind, which will eventually join with the incoming Rockies/So. Plains system, creating a long period of daily storms from Texas, Ok, and points east.

For tomorrow and early Saturday, the GFS has had a bullseye for 5 straight days now offshore Galveston, sometimes pulling it inland to around Houston and Lake Charles. I'm a little concerned when GFS is this bullish and consistent on a rain max around there, usually its a sign its seeing a legit threat of flooding. There will be good gulf inflow and a jet streak (maybe more than one) and good diffluence with such a nice upper low coming to a stall soon, that will be the recipe for some area to really get nailed with up to 5" of rain, maybe even more. When the week is said and done I won't be surprised to see Dallas, Houston and Birmingham all top 3" of rain. Of course one big thing to worry about further north is convective robbing. The more linear along the Gulf coast, atleast that will rob the Tennessee Valley at times, but since this is a multiday event, I have no doubt good rains definitely spiral inland very far north toward Tennessee. It's a fun setup (to me all rain is fun). I just wish there was signs of major rains further east in Ga to the Carolinas where the drought has been ongoing a long time, its much wetter west of the Apps (even though I know some areas there are too dry). One other mentionable could be how the ECMWF model builds an Ohio Valley or Lakes ridge next week. I'd like to see that happen esp. furthern north around the Lakes, as that would almost assure the southern system gets to drift in the Deep South even longer. Hopefully we get this type of flow to work out once in June, as that's when it would really, really be muggy and the atmosphere would be extremely primed and drop a lot of rain at the drop of a hat...just from daily heating. Anyway, didn't mean to get that long winded, enjoy the rain!

Great write up, man! Feel free to be as long winded as you want, lol. I've been missing those :) When this recent front finally sagged in, it brought hours and hours of light, steady rain. And thats what I'm hoping for this go around too. Much rather have days of light rain, than an inch an hour for two hours, then done. T

Robert, thanks for the update. Just like old times...

However, I must say...I'm hoping Atlanta can avoid a washout Monday afternoon/evening. Heading down to watch the Bravos...sure would be a long trip down and back for a rain out.

Great post! Me too. Good thing we got this rain this past week.

A gorgeous day here in Savannah today. After three days of very nice rains (couple of inches), we got rewarded today with bright blue skies (with some clouds late), TD's in the 40's, and a pleasant breeze.made for a great walk today! Ahhhhh!

Well that was a big time under performer for MBY...unless you live in the western half of my county where 2-3" was common. Ended up with .26" on Tuesday and only .08" yesterday.

Nice and cool this morning at 44.4....brrrr....

Not even that here. I got a whopping 0.10 total. The last month or two has really sucked here. Lost count on how many times rain either woefully underperformed per the models and forecasts or was missed by a few miles. Not sure I've seen the models bust so badly on rain amounts here so many times in a row. I might be wrong but it sure seems like one of the driest springs here in quite in a while.

Fortunately/unfortunately, I've had a lot of things going on that have distracted me from screwjob after screwjob but I have not been this bored with the weather...from late fall through now...I don't think ever. I just hope we have some tropical systems this year or a wet summer. From an active weather perspective, it has just sucked for a half year now..and it's really been depressing.

That's how it was here from 2005 until about March 2009...the longest boring stretch ever for me. I lucked up on the Summer storms last year for once. Good news is El Nino is brewing so better (more active) times are ahead.

That makes two of us :hug:

Normal would be a very welcomed change :wub:

Hey, Dr. Content! Surely you are doing more than walking what with the roasting 90's you've had. I know you got out the boogie board and skimmed alongside the sand when it got so hot :)

I hope the next time you're coming up 75 you'll drag some of that good rain with you! T

The 12z GFS is spitting out some nice rain totals over most of the SE for early next week.Looks like a slow moving low going across.

1.5'' to 2.5'' across the piedmont of NC,3''to 4'' across the mountains of NC.Let's see if it holds though.

It looks reasonable. All models now come in looking more in tact with this system...its very healthy looking and will almost literally come to a crawl as it gets closer to the Miss/Ala region. Both GFS and the new ECMWF want to create some kind of cutoff along the east coast possibly near SC, NC or even east Florida by next Friday. Before then though, some very decent rain amounts and the areas that missed out in central GA to central Carolinas should get something pretty decent this time since its a slow mover and not necessarily just a frontal passage.

Just updated my site with graphics and text discussion and anyones welcome to view the new post (put this one in the free public section - just click "public"). Have a great Mother's Day weekend to all the moms :)

39.0° chilly degrees this am in Weaverville. never made it out of the 60s yesterday. Looks like a chamber of commerce day with a forecast high of 73° today.....of course I have to work!

Ya it was down right cold this morning! Had a low of 36 degree with frost! I was a little suprised that we had frost this late and got as cold as we did. Just a picture perfect day today. Partly cloudy high of 68 degree and a slight breeze. Wish everyday was like this in summer.

Here is the latest one. Looks like there has been improvements. 2mpzwhs.png

Sure as hell has not been any improvement here. It's already dusty after that "big rain" I got. Grass is dying, lakes and creeks are way down and it's only may. And to add insult to injury, areas southeast of me got several good storms this week, in some cases adding up to 3 plus inches. Not a drop here.

Hey guys, got a question. My employer is transferring me from Durham to Charlotte in a couple weeks and I'll probably end up living somewhere either along the I-485 corridor in eastern Mecklenburg County, or maybe in Cabarrus County out toward Concord or even Kannapolis (my job is off Mallard Creek Church Road close to I-85). I know the weather's not really going to be all that different from here in the Bull City since it's only a 125-mile move, but is there any more chance of snow in the CLT metro area than in the Triangle? Thanks.

It is not much of a difference, but generally Durham gets more snow than the Charlotte area. Some years, it can be a significant difference, mainly because RDU is more likely to get in on Noreaster action than Charlotte, and is usually colder during major Arctic outbreaks.
