Oklahoma Weather Discussion - February/March 2013

The RAP pretty much kisses chances of heavy snow in OKC goodbye:

[Anonymous.]

My temp here in OKC is sitting @ 41 still.

I definitely figured I would be in the upper 30s by now. With clouds increasing in the SW part of the state, this is going to be ridiculously close for the metro.


Just turned on the local news, KFOR doesn't even have the updated WSW... Totally clueless.


Here is NWS in Norman continuing the back pedaling:

[Anonymous.]

Wet-Bulb temperature continues to drop slowly. OKC is @ 34 on north side, 36 south.

My air temp is now 40, it touched 39 just a bit ago.

[s00nr1]

I think at this point Anonymous we should all just be hoping the falling precip will do the cooling.

[Anonymous.]

Yup, it will come down to just a few degrees,


Melting rates will also be high due to warmer ground temperatures, not bone chilling air temperatures, AND snowfall during daylight hours... This will be a great event for the drought. Even if we stay rain in OKC [which i doubt].

Wtf is "wet-bulb"??

LOL. Sounds like a porn euphemism.

Wet-bulb temperature - Wikipedia, the free encyclopedia

The wet-bulb temperature is the temperature a parcel of air would have if it were cooled to saturation (100% relative humidity) by the evaporation of water into it, with the latent heat being supplied by the parcel.^[1] An actual wet-bulb thermometer indicates a temperature close to the true (thermodynamic) wet-bulb temperature. The wet-bulb temperature is the lowest temperature that can be reached under current ambient conditions by the evaporation of water only; it is the temperature felt when the skin is wet and exposed to moving air. Wet-bulb temperature is largely determined by both actual air temperature (dry-bulb temperature) and humidity, the amount of moisture in the air.
The thermodynamic wet-bulb temperature is the minimum temperature which may be achieved by purely evaporative cooling of a water-wetted (or even ice-covered), ventilated surface.

Was just about to post the definition as well.

Right now ~11:35pm the wet-bulb is 34 in N OKC and 33 in S OKC.



I just looked outside once again (I am in N OKC) and the skies are CLEAR. My temperature says 39 right now.

[ZYX2]

According to the Mesonet it is 33 near my location in Bixby. Hoping for it to drop a few more degrees before clouds move in!

[Anonymous.]

Closest thick cloud cover is just across the SW border of OK.

This is going to allow temperature to drop steadily as we head into the midnight hour. Since my last post my temp has dropped to 38, and the mesonets around the OKC metro have dropped 2-3 degrees. I am telling you without cloud cover, we will get very close to 32. Add in precip falling and the wet bulb effect is easily making us snow very early on.


Well I am going to get some sleep i suppose since work exists despite fun hobbies in weather.


I will probably wake up with excitement multiple times like a child on Christmas Eve. And as I do such, I will post updates about current conditions best to my ability.

I'm still at 45 degrees here in Norman. I wonder why the temp here has remained fairly steady?

Moisture content of the air is slowly increasing, so that's going to play with the temps some. Wind also picked up a good deal up until an hour ago. Also maybe a little urban heat effect happening too. Shouldn't last much longer though. Temps are falling off pretty good as wind is set coming form the NE now. Spencer is down to 36, same up in Chandler and then upper 20s just NE of there. El Reno is down to 32 now. As I'm typing this and seeing the new mesonet reports coming in, the temp in Norman has dropped 2 degrees just with the wind stopping...down to 41 now. Roughly falling about half a degree every 5 minutes at this point.

One more post before retiring for the evening.

Current radar images showing wide spread and rapidly development showers and thunderstorms to our SW. Looks like the freezing level is around 3600' over Central OK and down to 3000' over SW OK.

Latest HRRR run has precip change over for the Metro area starting around 9AM on the far west side. With change over in the city around 11AM-1PM now.

Through 2PM here are the snow totals...

[Anonymous.]

Sitting at 38 here ~ 3:30am.

Temps are having a very hard time making any further progress. Cloud cover over majority of state now. Wet bulb for OKC is right at freezing and 33. Bouncing back and forth. Unless the temps can drop 3-4 more degrees in the next 3 hours the sun will begin counter acting the entire event.


The precip shield is entering SW OK right now. Temps down there are about the same as in C OK so it will be interesting to see what happens. If the low can wrap up and cool itself off we may see faster changeover. Really the only parts of the state at or below freezing is the NE, far N, and panhandle.

[Anonymous.]

WSWarning extended another row east. Travelors advisory for everyone around it.

Storm is really trying to wrap itself up. Heavy snow about to move into W OK.

Too bad temperatures stalled out, this would easily be 10+ inches over much of the state. At least we all know it is beneficial.

[ZYX2]

The GFS keeps this storm a snow event for much of he state, while the NAM shows the snow never making it to most parts of the OKC metro or west of I-35. We will see how this plays out.

[Jrunner]

It's pretty much all snow/sleet at NW Expressway and Portland already

[judysue]

Al Roker flashed a snow total map on the Today Show this morning with 9-12 inches from Elk City and over the metro. Where is he getting that?

[catch22]

Rain at WRWA still. A few flakes every now and then.

[BrettM2]

Turning to slush/freezing rain in S. Edmond/N. OKC.

[SoonerDave]

Yeah, getting reports that far west OK County is starting to see snow.

[Anonymous.]

Just got to work in downtown OKC.

Heading down Broadway Ext was 80/20 rain/snow.

35 degrees.

[LocoAko]

NWS has a Winter Weather Advisory out for 1-3 inches while the Weather Channel said up to a half foot possible in OKC. Today should be fun.

[venture]

So recapping, Winter Storm warning from Enid to Yukon to Anadarko and back to the west and southwest. Winter Weather Advisory (there is no such thing as a Travelers Advisory) surrounding that for the other counties in the OKC metro area except for Pott County.

HRRR showing anywhere from 2 up to 8 inches across the OKC metro area. Still mostly rain in Norman temps at 34. Though it'll start mixing fast...
