Another one…
November 29, 2010

After a very nice but windy weekend, we have another cold front pushing across the state.  The coldest air is lagging a little behind the wind shift line, but afternoon temps will feel colder than your lunchtime temps.

Lows tonight will be in the “bone chilling” category.  Wind Chills will be in the teens.

Coldest Morning Of The Season
November 26, 2010

You will certainly need the coats this morning!!  It is quite chilly with temperatures in the mid 20s and some locations are seeing wind chills in the single digits.

 

 

Expect a rebound later today though.  Lots of sunshine with highs in the mid 50s!!

 

 

Saturday?  Well we start the day in the 20s again but the afternoon looks nice…here is your Bedlam forecast.

Winter Weather Advisory
November 25, 2010

A Winter Weather Advisory has been issued for a good portion of Southeast Oklahoma.  Heavy rain lingers in Southern Oklahoma, that combined with cold air filtering in, that means a winter mix possible with a slight chance for an icy glaze on some surfaces.  A few snowflakes are also mixing in.  Be careful on the roads.

An Unsettled Start…
November 25, 2010

Road conditions are still fine in most areas but southern Oklahoma is dealing with some heavy rainfall.  There is a light winter mix, and patchy at best in parts of Central Oklahoma and a few flurries possible in Northern Oklahoma, few and far between at best.

Evening Severe Risk
November 24, 2010

I suppose when you get a cold front as strong as we’re seeing tonight, added with some moisture and some instability, it’s possible that we could see a severe storm or two try to develop this evening. Right now, we’re thinking that there is enough of a chance that we could see storm develop this evening east of The OKC Metro that could turn severe. And while the risk for a tornado may exist, it appears that the sheer we’ll see for a majority of the day will be what is called “speed sheer”. Not much change in wind direction with height will prevent us from seeing a lot of rotation with these storms. But, as the front approaches, we’ll begin to see that directional sheer which means the risk for a tornadic storm may be present, though the peak area to see tornadoes looks to be in Missouri. So, for now, we’ll mention that we may see a tornado or two, but the main concerns here will be the risk of hail and winds during the evening hours.

Get Ready for Round 2!
November 24, 2010

I know we have given a lot of attention to the cold front coming in tonight, but looking ahead, another cold front will likely impact us by the end of the weekend, Sunday night into Monday morning bringing yet another big drop in temperatures. As of right now, it appears that this front will be able to drop temperatures into the 20s for lows and highs in the upper 40s. So perhaps not quite as strong as tonight’s, but enough to drop those highs again to being just below normal. And this should not be a huge surprise, but this front looks to be a big wind producer. Winds just above the surface (850mb) could be in excess of 50 kts, meaning that at the surface, taking friction into account could kick our winds over 40 mph. Put a kite on your list of things to buy on Black Friday.

Thanksgiving 2009 vs. 2010
November 24, 2010

Reaching 59 degrees should not be a difficult thing to this time of year. But apparently tomorrow, it will be. So, if you’re comparing this year to last, then, then look for some major differences between the 2 years. Last year, we were in the ballpark of seeing a normal Thanksgiving. But this year, a strong cold front will likely mean that fires will be necessary in the fireplace to stay warm. It’ll feel festive… I suppose..

Cleared for Departure on 18R…
November 23, 2010

Flying out of Oklahoma City may not be that big of a deal tomorrow with southerly winds expected all day,planes will likely be using runways 18R(right) and 18L(left) all day long. (This means you’ll be taking off to the south). And again, while weather locally shouldn’t pose much of an issue for flying, the weather at other airports may. And in some cases, could lead to some delays and perhaps… I hate to say..a few cancellations.

Let’s talk good news first: Flying south should be no problem at all with Texas Hubs not reporting any weather delays. But, flying west towards Denver and Salt Lake City may be a challenge. Strong winds and a departing snowstorm will mean that flights will be delayed. And so keep in mind that even though the weather will be dry here in Oklahoma, flights operating in other states will set up a chain reaction on delays across the nation. And, if you don’t like bumps, well, this next graph will probably put a frown on your face….

The seat-belt sign will be lit for most of your flight, especially headed west bound as a massive snow storm will create atleast moderate turbulence across a good portion of the left coast between the altitude of 10,000 and 45,000 feet.

Cold Front: Latest
November 23, 2010

Well, we’re one day closer to our much advertised front and it appears that the models are starting to agree a little more. The graphic above shows where the GFS and NAM model have the cold front positioned at about 6pm on Wednesday. The NAM, which yesterday, was the slower of the models has started to agree more with the GFS model. The GFS has slowed down some as well. So, the latest now is that the GFS model is somewhat slower, the NAM model is much faster now than yesterday. But, keep in mind that the models can sometimes have a hard time handling these cold fronts, and it may still not have the exact timing down, even 24 hours out.

Grab The Hand Warmers!
November 23, 2010

After a few warm mornings, it appears that the cold has moved back into Oklahoma. Sunday morning, we only dropped down to 59 degrees, yesterday morning, we were at 65 degrees. This morning, 38 degrees! A drop in almost 30 degrees! And, things will likely get even colder by Thursday and Friday.
