Short term model guidance keeps most of the KS activity up there, but there are some indications of morning activity around I-35 and to the east. We'll just need to watch where the outflow boundary sets up tomorrow.

Tonight's GFS runs shows disgusting temps through next weekend. There is a front in Northern Oklahoma on Wednesday that will keep temps down and maybe some precip. Maybe we'll luck out and it'll push south or an outflow boundary will come down and give us a chance to break the 100-110 heat we'll have most of the time period.

Venture, I've noticed you use the term "luck out" several times. I wouldn't want that! Luck out generally means bad luck. I want good soakin rain every few days.

"I went to the casino and spent $100 to win. I guess it was not my day, cuz I luck out on the games." Get it, Venture?

We need and want the rain! http://l.yimg.com/us.yimg.com/i/mesg/emoticons7/63.gif

Never heard it taken that way, but then I didn't grow up down here.

It's okay. It is how I knew of the meaning all my life.

We got some storms coming into the state from Kansas right now.

Hopefully those will spead a bit to the west and give us relief.

Those storms should stay east. There is some islolated activity developing now in Kingfisher County and north of Medford. This will be the general rule for the night and morning - isolated pop up showers and storms. If we get a good outflow boundary from the complex in NE Oklahoma, that could help spur more widespread activity for at least a short time on Thursday.

I hope the rain holds till after sunrise. http://l.yimg.com/us.yimg.com/i/mesg/emoticons7/63.gif I'm not done replanting the flowers. I plan to finish in the early morning at sunrise.

You two keep some late hours!! Looks like the rain missed us again. A few showers trying to go up just west of 35 south of Purcell, hope they develop northward.....I think our window of opp. is short this morning.

Thunder

WSS, I've been up all night and I'm still here. :LolLolLol

I'm hoping for some sort of an outflow boundary somewhere nearby that will hopefully give us some rain.

That should be it. Cap this morning is ridiculous in strength, so our window already passed.

Hey, Venture, this is admittedly not an OKC-specific question, but could I possibly trouble you for your thoughts on the general weather outlook for the southeastern US over the next week? Obviously I"m not asking for something specific, realize that's not possible for so broad an area, but I'm thinking in terms of driving weather late next week between here and SE toward Alabama and FLorida...

Its looking here like its going to be HOT next week, and I know the general pattern this time of year is steamy with the periodic storm....just wondered if anything out of the ordinary might be brewing.

Thanks!

So, I guess that is it? All we got is to hope that the daytime heating spark something, right? It is the summer and we technically have a very slim chance each day, right?

As expected, NOAA official declared the start of an El Nino weather pattern. Looks like it is expected to last through the winter. Right now it isn't a very strong one, which would tend to put us in a more drought prone pattern. If it gets stronger, we get into an opportunity of cooler weather and more rain. We'll see how this plays out over the next several months.

Thanks for the posting on the el nino, Ive been meaning to read up on it and your post will give me a start. Several questions but I'll leaf through your links before asking anything you might have already answered. I know el nino's arent good for tropical development in the atlantic though.

Just noticed that Buffao is already at 98 degrees at 8AM. WOW.

I'm disgusted at how NOAA put most of the central portion of the state to be in a worsening drought. How dare they jinx our weather! I guess they are testing some sort of top secret weather equipment to force storms to go around us.

Venture, that map just does not add up how most of the areas around us seem to be "normal" while a lone portion (that includes us) suffer the drought curse.

venture

Well we aren't alone. Most of the panhandles, eastern NM, SE CO, and the vast majority of Texas is in a drought (extreme to exceptional in southern TX). And really when you look at summer months, the highs usually setup over us or this general area and you get the ring of fire effect. So you normally get the monsoon season in the Rockies, the storm complexes in the central plains (like what is currently going on), and the storms typically dive SE through MO, AR, etc.

Plus we don't really have the vegetation around here that helps to lock the moisture in. We'll need to play a few more million trees to help that out. LOL

Vegetations and trees help lower the temp and bring in more rain?

They help keep the temps down and retain moisture in the soil.

Why don't you start a movement for MAPS4?
