General Weather Discussion - August & September 2017

[OkieHornet]

With all this rain, our neighborhood yards are being inundated with mushrooms. Yuck. Any sneaky trick to getting rid of them??

Be sure to use gloves or something to pick them up with other than your bare hands - they stain fingers pretty good. speaking from today's experience ;–)

The ones in my neighbor's yard are enormous. Some of the caps are honestly approaching the size of dinner plates. Pretty gnarly.

My mother-in-outlaw's yard looks like she started a shroom farm.... My plants and yard think it's spring again. Even my cool season grass is coming out of dormancy.

I won't touch a wild 'shroom for any reason. I scoop 'em up with the same flat shovel I use to pick up ye olde doggie debris.....I did read that a dose of nitrogen fertilizer might help fend them off some if you notice them moreso in your yard than a neighbor's...

Cumulus beginning to organize to the northwest. The show already starting in N OK.

Storms in C OK will be after dark.

FLOOD WATCH

Updated: Wed Aug-16-17 02:12pm CDT
Effective: Wed Aug-16-17 02:45pm CDT
Expires: Wed Aug-16-17 06:00pm CDT

Severity: Moderate
Urgency: Future
Certainty: Possible

Status: Actual
Type: Alert
Category: Met
Areas affected: Cleveland; Hughes; Lincoln; Logan; McClain; Noble; Oklahoma; Payne; Pontotoc; Pottawatomie; Seminole

Message summary: ...flood watch in effect from 7 pm cdt this evening through thursday morning...
The national weather service in norman has issued a
* flood watch for flash flooding of creeks and rivers...and low lying areas for portions of central oklahoma, east central oklahoma, northern oklahoma, and southeast oklahoma, including the following counties, cleveland, kay, lincoln, logan, mcclain, noble, oklahoma, payne, pontotoc, pottawatomie and seminole.
* from 7 pm cdt this evening until tomorrow morning.
* thunderstorms will occur this evening and through the night over areas that have already seen heavy rainfall amounts. This increases the potential for flooding or flash flooding. Precautionary/preparedness actions...
A flood watch means there is a potential for flooding based on current forecasts. You should monitor later forecasts and be alert for possible flood warnings. Those living in areas prone to flooding should be prepared to take action should flooding develop. Be especially cautious at night when it is harder to recognize the dangers of flooding.

Line of severe storms moving into the NW metro right now. Again flash flooding and frequent lightning main culprits. Initial gust of wind could be up to 45 mph.

[d-usa]

Drove from North of Memorial to just west of Will Rogers, that was quite the lightning show out there.

It also doesn't take a lot of rain to make the flooding appear.

[BG918]

The Oklahoma summer drought has almost been eradicated. Amazing turn around from where the central and western parts of the state were a couple months ago.

[Anonymous.]

Could still see another round of rain/storms late tonight into Friday morning. Depending if they can hold together exiting the SW KS and TX PH corridor. Models are leaning to the doubtful side of this scenario.

Then one more shot @ a similar scenario later Friday evening.

After that, the weekend looks muggy and hot, and currently model trend for next week and beyond is indicative of a return of the death ridge.

[Anonymous.]

Rain is not likely anymore for tonight. Perhaps far NE OK could see some action. Otherwise this weekend will be very hot and muggy.

Models are reversing the trend of upcoming hot weather, and a potential tropical influence will begin impacting our weather next week. Potentially highs in the 80s again with rain chances.

[Anonymous.]

Showers and storms will develop this evening roughly along the I-40 corridor. Favored area is just south of I-40 and especially across W & SW OK.

This will be the part of a stalled front that will bring back the highs in the mid 80s through the weekend.

Then eyes turn toward the GOM as a potential tropical storm will develop and impact the TX coast.

[Anonymous.]

Storms should begin developing over the next few hours.

Mesoscale Discussion 1553
NWS Storm Prediction Center Norman OK
0254 PM CDT Tue Aug 22 2017

Areas affected...Portions of OK...north TX...the TX Panhandle/South
Plains...eastern NM

Concerning...Severe potential...Watch unlikely

Valid 221954Z - 222230Z

Probability of Watch Issuance...5 percent

SUMMARY...An isolated severe-thunderstorm risk is expected to exist
into the late afternoon and early evening hours. Watch issuance will
be unlikely.

DISCUSSION...The following zones will be focus areas for convective
deepening into the late afternoon hours:
(1) an outflow boundary arcing from east-central OK toward the Tulsa
area,
(2) differential-heating-induced baroclinicity on the warm-side
fringes of a multi-layered cloud band from the Wichita Falls and
Lawton areas toward Norman and Tulsa,
(3) modest synoptic frontal convergence from east-central NM into
west-central OK (convectively influenced in NM), and
(4) deeper baroclinicity along a stronger-frontal segment just south
of the northeast OK/southeast KS border.

Modifications to the 17Z and 18Z observed soundings across the area
suggest that capping aloft continues to erode as pockets of at least
filtered insolation continue on the warm sides of the aforementioned
zones of convective initiation. Related convective inflow is
becoming increasingly buoyant, with MLCAPE increasing to
1000-2500 J/kg -- highest magnitudes where insolation has been
strongest. While pockets of ongoing clouds are locally muting
diabatic surface-layer heating in parts of OK, eventually
strengthening/expanding cold pools will likely breed growing
convective coverage/intensity during the next few hours across the
entire area, amid DCAPE upwards of 1000-1250 J/kg. Sporadic severe
wind gusts may accompany collapsing convective cores into the
evening hours, though weak effective shear will limit convective
organization and severe coverage. The isolated severe risk will tend
to spread southward with time owing to preferential growth of
incipient updrafts into the more buoyant air with southward extent
across the region.

We're getting quite a bit of hail right now in the Midtown area. Not really large--maybe pea-sized--but it's been going on for about 5 minutes.

[corwin1968]

Nice show up here on the far NW side of OKC. Driving sheets of rain, RUMBLING thunder and huge, long lasting lightening bolts.

[Pete]

Holy cow! Well over an inch of rain in about 10 minutes here near Penn Square.

[Pete]

[Pete]

3 inches at my house in about 30 minutes... And counting.

[Anonymous.]

OKC proper was the winner with rain. That one cell blew up directly over downtown and just kept expanding while staying stationary. Then the main cluster from the north swept through. Solid 2-4" depending on where you are located in the metro.

Looking ahead, we are going to be affected by the tropical storm that comes up into TX, this may cause our weather to be drier as it will be sucking all the moisture and energy down to it. On the contrary, this could bring in chances of rain/storms if the system goes far enough north to bring in some bands.

[FighttheGoodFight]

Great rain in Norman. Many roads were closed due to flash flooding. Nice to not worry about the sprinkler system for a few weeks now.

Yep, we were right underneath it and it was pretty fierce. The hail, although not too large, shredded up a bunch of our plants and left leaves and debris all over the sidewalks and yard. No major damage though, and glad to not have to run the sprinkler for a while.

[SoonerDave]

Amen. I'm in the phase of the year where I'm starting to cut the grass taller as we at least approach the dormancy season, but with the rain (and a well-timed dose of fertilizer), the grass is growing like crazy and I actually may have to start mowing every other day at least for a time. Gonna leave the sprinklers off for a while!

GFS is keeping most of the activity in Texas with movement more NE toward the middle of next week. Looks more like a potentially historic rain event for Texas and Louisiana, and maybe into Arkansas next week with most of OK in the dry slot. Things can change though..

[Pete]

What was only a slight chance of rain has turned into 2+ inches of precip at my house, and still counting.
