Joining Sept & October today for this go around. Fall severe weather season starts to kick in towards the end of September into October. Looks like it'll be plenty hot for the first chunk of September. Also in an effort to clean the first post up a little bit, I'll be moving a lot of resources/tutorials over to the WeatherSpotlight page (where the chat room is) to help out - see links below to get to them.

Front coming through. Line of light to moderate showers from Sayre to Arapaho to Watonga up to Enid and Newkirk. Should be over here in a couple hours. Could see activity pick up and some stronger storms form. Not a widespread soaking unfortunately. We need it at this point as drought conditions are starting to come back.

Looks like temperature relief is here. But the rain is not. Most of the state headed towards the span of a month of no rainfall unless something changes. Was really hoping the grass would stay green the entire duration of summer.

We (DFW) had some light rain Sunday night and halfway through Monday which was nice. The 10 day forcast is calling for mid to upper 90's and dry. That's still better than the 103-105 we had last week.

Many places in Oklahoma fell a bit short in getting the normal amount of rain for August, so there's not much of a moist buildup to cope with an unusually long dry period.

Drought conditions coming back.

It's about time for a tropical system to pay us a visit...

Amazing how OKC is so few counties away from being in exceptional drought.

It's about time for a tropical system to pay us a visit...

I don't think the first hurricane of the season has developed, yet. I think, for now, we can handle one better than in 2007 and 1986.

I don't think the first hurricane of the season has developed, yet. I think, for now, we can handle one better than in 2007 and 1986.

No hurricane yet...the 8th tropical system is in the Bay of Campeche right now.

Change is here. Every day from here on out should gradually get cooler. Dropping us to highs in the low 80s by mid next week.

Rain chances returning same time. Slight chances into the weekend. GFS picking up on the possible tropical system in the gulf bringing us rain next week. It is too early to be certain, but any large amounts of rain over small time periods will result in easy flash flooding due to the top layer of soil being rock hard right now. (~25 days without precipitation)

Sheeeesh I live up there and get flooded out 3 times this year, I move to DFW and it quits raining.

Finally moving out of the boring time of year. Guess I need to start cleaning up the website and making it all pretty for the Fall storm season. :)

Drought Monitor is updated finally and has at least some drought conditions now for the entire state again.

the majority of the state .. 55.36% is not in drought correct?

Imagine above is pretty clear. 100% has at least some drought conditions from D0 to D4. Not sure where you are getting your numbers from.

He was probably referring to the "abnormally dry" terminology used which is still drought conditions or developing drought conditions.

i had the sept 3rd image still up ... must have been cached a reload took care of of that .... sorry about that

Noting that it looks as though we might be in for some rain here in OKC this afternoon. Boy it is hazy and muggy outside.

Had a small shower on Rockwell between Hefner and NW 122; drove out of it by the time I got to NW 122 and Council though...

This may not be the right thread, but I wanted to mention that the NOAA statewide tornado records now shows 56 tornadoes during the month of May this year. Maybe this wasn't an average/below average season after all, from a scientific standpoint.

OKC can't even get bypassed by the weak weather systems moving through the state. But then it's the first day of the fair to factor in.

It was pouring nice and solid today along May Avenue between Britton and Wilshire and a lot heavier to the south and north. It was nice hearing that thunder off in the distance!

1" of rain at 2nd/santa fe in edmond last night with that storm.

My buddy had his picture shown on KFOR last night. He lives over around Danforth/May and he received 4.5". Crazy that in 3 or so miles you're looking at that much difference...hence the term localized flooding.

This isn't really Oklahoma, just didn't want to start a new thread. Thought this was really interesting though for those who want to watch.

Showers and storms firing in SW KS and TX Pandhandle. Will eventually be shoved south as front moves in.

Bring it on. Ready to try the new drains!

Looks like bulk of the rain will remain in Northern OK. Our next big rain maker should be late Thursday into Friday. I-44 corridor and to the Northwest about 70 miles could have a swatch of 1-3 inches of rain in there. Doesn't look like much of any in the way of severe weather.

Bring it on. Ready to try the new drains!
I'm afraid OKC finally got kinda bypassed by this time around, assuming you weren't in a gully washer where there was no rain gauge.

http://www.mesonet.org/data/public/mesonet/maps/realtime/current.24hour-rainrfc_front580.png

This afternoon should have a line of showers/storms from I-44 and south pop up. Marginal severe risk south of I-40.

I sure hope so. Today makes a month since we've had any rain at all over here on the East side. My grass is really struggling.

Yeah the rain has been pretty spotty...today is the same. We were dry as well but last week got the good downpour of an inch. The grass is still pretty much dead which is fine by me. :) I would like to be done mowing for the year. haha

OKC area better look out just in case Mother Nature is thinking about making up for it from bypassing OKC last night!

A lot of juice out there for storms to work with later this afternoon. With the sun heating things up, some instability will be in place for more tropical-type showers/storms.

You will either stay dry, or get dumped on.

Next batch popping up in SW OK moving NE very slowly. Also appears we have a boundary (well there are a lot of them out there actually) moving up from Chickasha-Pauls Valley that could be a focus of some activity here later.

The fair sure didn't get bypassed. The heavy rain and wind up to 50mph caused some fairly minor damage.

We are getting pounded in Harrah.

The drains work! Wheeeee!

MacArthur was pretty dicey north of Britton. Lots of people trying to get home right after that little storm passed by. I'm not proud of what I drove through to get home. Pretty crazy driving through that rain and wind. But it's nice to have a few drops after a dry month.

The fair sure didn't get bypassed. The heavy rain and wind up to 50mph caused some fairly minor damage.

Nope. I was passing I40 when it blew over I44 and knew the fair would get pounded

I heard that a microburst affected the state fair today...

Always loved how the State Fair seems to defeat our high pressure dome of hot dry weather. I think that is why I can't get into that show "Under The Dome". We live through that every summer.

Under the Dome would just make you mad though...especially wanting to throw something at the TV when Big Jim is on. Grrrrr. Anyway...LOL

Yeah the State Fair always seems to bring the rain back like clock work...just like the Arts Festival. :)

With help from the third wettest month of the year coming back like clock work--September.

Focus is on tomorrow night into Friday. Looks like decent instability could be in place for some severe weather. At the least, a good state-soaking.

Large rain shield moving across NW TX approaching SW OK.

This is tropical moisture that is being sheared off of Hurricane Manuel. This moisture will keep pumping up along this frontal zone that is moving through tonight. Look for showers and storms to develop ahead of this rain shield.

Models are having a hard time estimating rainfall and where exactly. Right now it looks like TX is going to get slammed over the next few days with this cool front + Manuel being shredded over the area + Invest 95 in the SW Gulf dancing around.

Yeah! We're gonna take a POUNDING tomorrow. When was the last time you had a really good pounding?

-Colton

Pretty decent storms moving into the OKC metro from the SW right now.

Remember the top soil is still very hard and flash flooding will occur easily with heavier downpours.

Heavy rain continues over the Metro area from Norman to E OKC to Chandler and Stillwater.

Strong to severe storms forming up over NW OK along the front. Cells move NE but line will move SE.

Stillwater got bypassed by that rain area with at best some sprinkles on the east side, which got a cool down to the low 80s. As mentioned, Stillwater's best bet for rain now lies in the line of storms that have developed in NW Oklahoma and Kansas.

Looks the heaviest was right on Brush Creek Road, so yeah...far east side of Stillwater and that's about it.

Do you know if our favorite dry lake to the NW in Canton received any drops of liquid percip today?

Do you know if our favorite dry lake to the NW in Canton received any drops of liquid percip today?

Here is a couple hours the line should be there.

Shower coverage is increasing over the area. Storms are increasing over NE OK and the NW activity remains but is much weaker than before.

Models did a good job. Here in central OK we didn't get much in addition to the storms that went through around 3pm.

S and SE OK will be the winners where areas are approaching 3 inches.

On the other hand, throw in some additional bypassing or diminishing of approaching activity and Stillwater at best got .04 the last couple of days. 48 hr. map shows much of western and north central Oklahoma fared little better. For today, much of Texas and Arkansas are trying their luck with some good rains.

Wow... Today was perfect! I hope everyone got to experience tonight's sunset. It was legendary!
