Oklahoma Weather Discussion - July 2013

So for those keeping tabs, I added up Norman's year to do date so far. Puts us just under 30" for the year...annual average is just over 37". If we are completely average for the rest of the year that would put Norman specifically at 45". That's double last year's rain fall and almost equal to 2012 and 2011 combined. It will also be the highest annual rainfall since 2007 when we had over 56".

The rain is trying to make it's way down here... Hope it holds together.

It didn't... fell apart just as it got here

Tulsa and surrounding areas had a lot of damage from the storms last night. Trees and power lines down across the city. PSO is still reporting over 100,000 without power.

..flash flood watch in effect from thursday evening through
friday evening...

The national weather service in norman has issued a

* flash flood watch for portions of central oklahoma and
northern oklahoma...including the following areas...in central
oklahoma...kingfisher...lincoln...logan...oklahoma and payne.
In northern oklahoma...garfield...grant...kay and noble.

* from thursday evening through friday evening

* excessive rainfall is expected to fall over areas where recent
heavy rainfall has already occurred.

* flash flooding can lead to road washouts and unexpected
sinkholes. Rivers...creeks...and streams may rise out of their
banks...flooding nearby residences and businesses. Never attempt
to cross water covered roadways if you cannot see how deep the
water is...turn around dont drown.

Precautionary/preparedness actions...

Monitor weather forecasts and information. Make plans to get to
higher ground if flooding happens.

This is the projected totals as of now:




Looks like Canton Lake will have a nice drink.

Looks like Canton Lake will have a nice drink.

That would be really good. Hearing this is the same low pressure system that gave us all the rain last week...just that its no longer 'retrograde' :-)

[Praedura]

Muchos precipitos in Edmond this morning. Plants happy. Me happy.

Near Amarillo and the western PH just have to be ready to float away by now. A few hours now of storms that aren't moving at all.

Near Amarillo and the western PH just have to be ready to float away by now. A few hours now of storms that aren't moving at all.

And all downstream rivers and lakes are saying thank you.

Heads up for those that may wonder...

KINX - nexrad serving NE OK got fried last night from lightning and is down until repairs can be made. No ETA on return.

[zachj7]

That system was never "retrograding" in the dynamical meteorological sense. It was just a shortwave in the easterlies (Going east). Uncommon this far north, but it certainly wasn't retrograding. TV meteorologists misuse that word. There's a difference between a shortwave going east and retrograding.

At least all the grass is green which is a nice change for late July/August compared to the last few years.

[venture]

Slight Risk today west of a line from Newkirk to Guthrie to SW OKC to Marlow to Grandfield. Hail/wind main threats. Flooding threat kicks in later North of I-40 and east of I-35.

...CNTRL/SRN PLAINS...


FORECAST IS SOMEWHAT COMPLICATED BY AREAS OF ONGOING CONVECTION.
SCATTERED STORMS PERSIST FROM THE TX PANHANDLE NWD THROUGH WRN KS
INTO SWRN NEB. THIS ACTIVITY IS EXPECTED TO SHIFT EWD OVERNIGHT WITH
A GRADUAL DECREASE IN COVERAGE...ALLOWING THE UPSTREAM BOUNDARY
LAYER TO RECOVER OVER THE CNTRL HIGH PLAINS DURING THE DAY. IN WAKE
OF EARLY STORMS...THE ATMOSPHERE IS EXPECTED TO BECOME MODERATELY
UNSTABLE WITH 1500-2000 J/KG MLCAPE EXPECTED ALONG WRN FRINGE OF
MOIST AXIS. A LOW AMPLITUDE SHORTWAVE TROUGH OVER NRN CO WILL
CONTINUE SEWD INTO THE HIGH PLAINS BY AFTERNOON. STORMS ARE EXPECTED
TO REDEVELOP OVER THE HIGHER TERRAIN OF CO/WY AND ALONG LEE
TROUGH...POSSIBLY AIDED BY FORCING FOR ASCENT ASSOCIATED WITH THE
SHORTWAVE TROUGH. THIS REGION WILL EXIST ALONG SRN FRINGE OF
STRONGER WINDS ALOFT WITH 30-40 KT EFFECTIVE SHEAR SUFFICIENT FOR A
FEW SUPERCELLS WITH INITIAL ACTIVITY. STORMS MAY EVENTUALLY
CONSOLIDATE INTO AN MCS AS THEY CONTINUE EWD DURING THE EVENING AND
OVERNIGHT. LARGE HAIL AND DAMAGING WIND WILL BE THE MAIN THREATS.

Not really sure what you are disputing here zach but the upper level system that affected our area approximately 10 days ago did indeed "retrograde."

That system was never "retrograding" in the dynamical meteorological sense. It was just a shortwave in the easterlies (Going east). Uncommon this far north, but it certainly wasn't retrograding. TV meteorologists misuse that word. There's a difference between a shortwave going east and retrograding.

At least all the grass is green which is a nice change for late July/August compared to the last few years.

[Anonymous.]

Yea that system was pretty much textbook retrograde low. And you keep saying east, when I think you mean west??

[Anonymous.]

Still on track for massive amounts of rain the next 36 hours.


GFS wants to do another short wave event Monday that dumps buckets over the northern half of OK again.




I would post the July rainfall totals as of now, but it is about to look even more outstanding over the next handful of days.

[SoonerDave]

Looks like I need to dump some fertilizer on my back yard and get some free watering in

Raining buckets out there...

Why are the news stations in wall to wall coverage?

[TaoMaas]

Why are the news stations in wall to wall coverage?

Because there's this strange substance falling from the sky...or at least there was earlier. lol Seriously, we were asking ourselves the same question. Seems like a bit of overkill.

[catch22]

Watching channel 5. This is rediculous, they are dispatching their helicopter to cover this??
