VALID 262000Z - 271200Z

...THERE IS A SLGT RISK OF SVR TSTMS LATE THIS AFTERNOON THROUGH
TONIGHT ACROSS MUCH OF OK...

...OK...
THE 1630Z OUTLOOK REMAINS ON TRACK ACROSS OK FOR LATE THIS AFTERNOON
THROUGH TONIGHT...AND THUS NO CHANGES IN SEVERE PROBABILITIES ARE
NEEDED WITH THIS OUTLOOK ISSUANCE. THE 15Z HRRR REMAINS CONSISTENT
WITH EARLIER STORM-SCALE MODEL SOLUTIONS USED IN THE PREVIOUS
OUTLOOK DISCUSSION SUGGESTING INITIALLY MORE DISCRETE STORMS DEVELOP
OVER NWRN INTO CENTRAL OK...WITH THE POTENTIAL FOR ACTIVITY TO GROW
UPSCALE INTO A LINEAR SYSTEM AS THE COLD FRONT MOVES INTO ERN OK
AFTER 27/05Z.

EARLY-MID AFTERNOON SURFACE ANALYSIS SHOWED AN AREA OF LOW PRESSURE
CENTERED OVER THE OK PANHANDLE WITH A FRONT EXTENDING SEWD THROUGH
NWRN TO CENTRAL /N OF KOKC/ AND INTO EAST CENTRAL OK. GIVEN RECENT
BACKING WINDS TO GENERALLY ELY N OF THIS FRONT AND SLY TRAJECTORIES
EXPECTED TO PERSIST OVER SRN OK AHEAD OF THE PROGRESSIVE SURFACE LOW
WOULD SUGGEST THIS BOUNDARY MAY TEND TO BE MORE QUASI-STATIONARY
INTO THIS EVENING. THE LIGHTNING OVER SWRN KS INTO THE NRN TX
PANHANDLE IS INDICATIVE OF THE STRONGER ASCENT ATTENDANT TO THE
SHORTWAVE TROUGH.

This is from NWS-Don't be surprised if you see/hear a watch for parts of central and western Oklahoma between now and 5 pm. Conditions are coming together for supercells to form in the far eastern Texas panhandle, and then move through parts of western and eventually into central Oklahoma. If you have outdoor plans this evening, you need to be especially weather aware! Allow yourself plenty of time to get to a sturdy shelter in a storm threatens! The most intense storms will have tennis ball size hail and we could even see a tornado or two. Stay alert!

MESOSCALE DISCUSSION 0558
NWS STORM PREDICTION CENTER NORMAN OK
0256 PM CDT FRI APR 26 2013

AREAS AFFECTED...WRN/CNTRL OK...FAR ERN TX PANHANDLE

CONCERNING...SEVERE POTENTIAL...WATCH LIKELY

VALID 261956Z - 262230Z

PROBABILITY OF WATCH ISSUANCE...80 PERCENT

SUMMARY...A FEW DISCRETE SUPERCELLS APPEAR LIKELY TO FORM BY 22-23Z
ALONG THE TX/OK BORDER AND DEVELOP SEWD INTO CNTRL OK THIS EVENING.
LARGE HAIL WILL BE THE PRIMARY HAZARD...BUT ISOLATED SEVERE WINDS
AND PERHAPS A TORNADO OR TWO WILL ALSO BE POSSIBLE.

DISCUSSION...19Z SURFACE ANALYSIS PLACED A 1011 MB CYCLONE IN THE
NRN TX PANHANDLE WITH AN ATTENDANT DRYLINE EXTENDING S/SWWD TOWARDS
THE PECOS VALLEY. A WARM FRONT THAT IS BECOMING QUASI-STATIONARY
EXTENDED E/SEWD INTO CNTRL OK TO THE ARKLATEX. CONVERGENCE ALONG
BOTH BOUNDARIES APPEARS TO BE STRENGTHENING IN RESPONSE TO THE
LOW-AMPLITUDE SHORTWAVE IMPULSE THAT WILL TRACK EWD ALONG THE KS/OK
BORDER...AS SURFACE PRESSURE FALLS HAVE INCREASED ACROSS SWRN
OK/NWRN TX. HERE...NEARLY FULL INSOLATION IS OCCURRING WITH SURFACE
TEMPERATURES WARMING THROUGH THE 70S INTO 80S AMIDST DEW POINTS
STILL RISING THROUGH 50S. THIS IS PROMOTING RAPID DESTABILIZATION
AND WILL YIELD WEAK TO EVENTUALLY MODERATE MIXED-LAYER BUOYANCY BY
EARLY EVENING.

12Z CONVECTION-ALLOWING WRF GUIDANCE ALONG WITH LATER MORNING HRRR
RUNS HAVE BEEN HIGHLY CONSISTENT WITH SIMULATING A BLOSSOMING OF
CONVECTIVE INTENSITY BY ABOUT 22Z. BASED ON CURRENT POSITION OF THE
SMALL CLUSTER OF TSTMS ATTENDANT TO THE SHORTWAVE IMPULSE...AND
INCREASING CU S ALONG THE DRYLINE...THIS SCENARIO APPEARS QUITE
REASONABLE. INITIAL DEVELOPMENT SHOULD BE RELATIVELY HIGH-BASED WITH
ELONGATED/NEARLY STRAIGHT-LINE HODOGRAPHS FAVORING SPLITTING
SUPERCELL STRUCTURES WITH MAIN THREATS OF LARGE HAIL AND ISOLATED
SEVERE WINDS.

Looking at current conditions out there right now...

Warm front currently extends from NW to SE across the state fron north of Woodward down to OKC and down to the SE, pretty much running near/along US 270. Moisture is decent across the area, not excessive, but decent. Best moisture convergence is going to be along the warm front and also back in the Panhandles near the triple point intersection with the Low. Best instability is going out in Western Oklahoma where the sun has been shining for most of the day.

HRRR has initiation around this time out to the NW. There are some storms in that area, but nothing out of control right now. It does forecast a couple severe supercells, which probably very large hail, moving SE into the OKC area by 8PM tonight. Tornado threat is fairly low, but any storm that rides the boundary might have enough local helicity to get things going. LCLs aren't bad at all today with the low level moisture. Today is just more of a big hail day though than anything else.

HRRR Forecast image for 9PM tonight...

I do have a garage. A wonderful, lovely garage. It's the first time in my life I've ever had one (since I moved into this house). I was driving home from helping a friend paint the trim and doors in her new house. I needed maybe 1-2 more minutes to make it home. Shoulda stopped at the gas station and hid under the awning when the wind hit. I knew it was coming.

Brief look ahead...

This is off of last nights 00Z GFS run. The 12Z run will be finished early this afternoon.

Weds May 1st - Strong cold front comes through. Rain/Storms appear likely. Severe risk in the early to mid afternoon before frontal passage. Temps in the 70s early falling to the 40s by evening and into the 30s overnight.

Thurs May 2nd - Dry, but wanted to note overnight lows back in the 30s again.

Friday May 10th - Storms early, moving east through the day.

Not really a lot popping up for the first week or so in May, which is pretty unusual. We'll see what the 12Z shows. The GFS takes the system that is coming through Wednesday and closes it off over the Ohio Valley. It leaves it there for a few days giving them a ton of rain and highs in the 40s. So having a feature like that can definitely snarl things up over us. If it happens we'll have to wait and see.

Is it just me, or is the weather, maybe even the climate, acting very strange lately? IN OKLAHOMA!?

No, it's spring time, though I do wonder what's with Oklahoma City for being subject to so many big hail storms, other than because it's the biggest target in the state.

It's not just you, and it's been happening for about ten years.

We have the coldest recorded temperature in the same year we have the highest recorded temperature. We have the rainiest year on record followed by years of drought. We have the highest recorded snowfall and then the next year we have temperatures in the 80s in January.

Yes, the climate is bizarre. It is extreme. I remember thinking the year we got nearly 60 inches of rain in Oklahoma we would soon be having some nasty drought.

I would say this spring is closer -- though cooler and slightly wetter -- to the average. The last two years have just been hot. Thank God that trend has reversed.

But I was talking to someone in farm country two weeks ago and he pointed out these late freezes have happened several years in a row and that farmers have not adjusted to the climate change. They need to, because it is destroying their crops.

You know I've always thought it would be neat if someone found a way to genetically engineer certain crops to withstand drought and freezes. You make TONS AND TONS of money if you did that and patented it. If no one does, maybe I could give it a shot lol, 10-15 years of research and dedication and surely something would breakthrough.

Anyhow, it is strange. I've lived here my whole life pretty much, except for the 5 years I lived in Dallas, but it seems very strange when compared to most other places. I've even had relatives from Colorado range say that our weather is nuts, now that is saying something. The other thing is, it will suck if goes from being this cold to a straight 3 months of 100+ degrees which is probably what will happen lol
