Very Windy This Afternoon
October 31, 2007

A fairly strong cold front is currently sweeping through the central part of the state, bringing strong winds with it. Ahead of the front, the winds are brisk from the south. Behind it, north winds are ushering some chilly air.

There is a wind advisory for the western part of the state, as we could see sustained winds there of 20-30mph, with gusts over 40mph. In the metro, winds in the early afternoon will be in the 15-30mph range, before beginning to taper off later in the evening.

Temperatures will fall through the 50s as our trick-or-treaters are hunting their bounty. Temperatures will really drop overnight, perhaps falling to near freezing in the northwest. There is a freeze warning up there for Thursday morning.

It will begin to moderate tomorrow afternoon. Tempeatures should continue to climb through the weekend, even reaching the 70s again on Sunday and Monday.

Easy Weather, Busy Day
October 30, 2007

The weather may be pleasant, but my day has been busy, busy, busy. So busy that I did not have time to do my Hardcore Weather video this morning.

So what is keeping my so busy? Well, it has to do with a lot of the behind the scenes things here at KOCO. Budget meetings, schedules, interviews…you name it, they all seem to happen at once. Tomorrow will be another jam packed day.

Thankfully our weather is quiet. I still expect a cold front to move across Oklahoma tomorrow. The front will cool us into the 60s, but there will be no rain. For trick-or-treat time it will be dry and cool with temperatures in the 50s and a brisk north breeze.

The easy weather will continue into the weekend with highs mostly in the 60s, but Sunday will warm into the 70s.

That’s all for now. Make sure you watch Eyewitness News 5 at 5,6, and 10 pm for the latest.

Tropical Storm Noel
October 29, 2007

Tropical Storm Noel developed yesterday with winds at one point up to 60 mph. It has since weakened with winds at about 50 mph, though some strengthening is possible. Noel has brought very heavy rainfall with life threatening flooding to Hispaniola, Haiti, eastern Cuba and the Bahamas.

Noel is expected to continue to move to the northwest for the next couple days and then make a turn to the northeast on Wednesday. At this time the forecast calls for Noel to make a turn to the northeast before reaching the Florida peninsula; however, a slightly slower turn could result in a Florida landfall.

Here is the latest track from the National Hurricane Center:

Even though it may seem a little late for tropical activity, hurricane season officially ends on November 30th. In some cases we’ve even seen tropical activity after this date. One example is in 2005 when Tropical Storm Zeta developed in late December.

A Couple Of Cold Fronts
October 29, 2007

The tranquil weather will continue this week even though there will be two cold fronts that will affect Oklahoma.

Tomorrow will be warm and windy with highs in the 70s. Southerly winds will gust to 30 mph.

The first cold front of the week will come through Wednesday afternoon. There will be no rain with the front, and temperatures won’t drop until late afternoon, so highs will still be in the low 70s.

Trick or treat weather will be dry and breezy with evening temperatures falling into the 50s.

Thursday and Friday will be dry and cooler with highs in the 60s.

The second cold front of the week will be late Friday into Friday night. There won’t be much moisture to work with, but there will be a chance of showers Friday night into early Saturday. The rest of the weekend will be dry with highs in the low to middle 60s.

A stronger front could affect the area by next Monday or Tuesday.

Heading Towards Halloween
October 29, 2007

The weather continues to be beautiful across the region on this Monday. All trick-or-treaters care about is, what’s Wednesday nights forecast?????

Well, it’s looking good, just a bit cooler. A cold front will sweep through the area on Wednesday afternoon, bringing in a quick shot of cool air and breezy north winds.

Here’s a look at some highlights of weather we’ve seen around the state on Halloween, courtesy of The Oklahoma Climatological Survey.

Overall, only about one out of five years has recorded significant precipitation during Halloween.The wettest year at many places across the state was 1998, although Durant, which holds the state record for the wettest Halloween with 5.35 inches, set its record in 1974.

Typical temperatures for October 31 are the upper-60s to low-70s for daytime highs and mid- to upper-40s for nighttime lows. The warmest Halloween temperature on record was 90 degrees, set at Durant and Ardmore in 1934. Most places in Oklahoma, however, set their records in 1950, when upper 80s were commonplace across the state. The coolest temperature on record for Halloween is 15 degrees, set at Goodwell in 1991 and at Clinton and Ponca City in 1993. Teens were common across the state in 1993, which set the mark as the coldest Halloween at many locations statewide.

Young trick-or-treaters need jackets about half of the time across most of the state, but those in the northwestern parts could use a jacket almost every year. There even has been a bit of snow during some Halloweens. The heaviest snowfall was in 1991, when Woodward recorded two inches and Goodwell reported 0.4 inch. A trace of snow was reported during other years at Enid, Clinton, Oklahoma City, and Ponca City.

A Frosty Friday Morning
October 26, 2007

Temperatures dipped well into the 30s across much of central and western Oklahoma this morning. Frost was widespread. Here are some pictures that I took this morning:

You can see the steam rising from this furnace pipe.
This was taken on KOCO property where we have a creek and a couple of ponds. The water is warmer than the air, so steam is seen rising off in the distance behind the trees.

This open field of grass was completely covered in frost.


Somebody’s car from the overnight shift was encased in frost, but the sun was starting to work its magic.


No frost on the pumpkins, but the grass was glazed.

Maybe now I’ll get to stop mowing.

The forecast still looks quiet. Dry through at least the middle of next week. Weekend temperatures in the 60s, but warming into the low 70s for a time next week.

Prepare For Frost And The Space Station
October 25, 2007

Temperatures tonight are going to fall into the 30s across much of central and western Oklahoma. The coldest weather will be in the northwest where lows tonight will be around freezing. In fact a Freeze Warning is in effect for far western Oklahoma. If you have some plants that you want to keep alive, make sure you cover them up tonight.

In central Oklahoma, a Frost Advisory is in effect for tonight as there is the potential for patchy frost with lows in the mid to upper 30s.
After tonight, the frost threat will end in central Oklahoma for at least the next several nights.
Here’s a space tidbit, the space station which is docked with the space shuttle will be visible this evening across much of the state as it crosses Oklahoma. Here’s a graphic will all the information.

Thanks to our colleagues at the National Weather Service for the cool graphics!

OCS Releases Climate Change Statement
October 25, 2007

Overwhelming observational evidence indicates that the earth is warming, and that the cause of that warming is mostly anthropogenic (caused by humans) in nature. Further, the vast majority of scientists that actually study climate change believe that warming will continue for the foreseeable future.

Of course, climate change has become a highly contentious topic in public discourse, with the waters being muddied by extreme viewpoints and concerns. So where does the truth lie, and what are the implications for Oklahoma? The Oklahoma Climatological Survey (OCS) has been mandated by the Oklahoma legislature to provide climate information and expertise which could be of value to the public, as well as to state policy- and decision-makers. In that regard, OCS has conducted a review of current assessments of climate change research in order to craft a definitive statement on global climate change and the implications for Oklahoma – detrimental and beneficial alike. The statement is based purely on the findings of the vast majority of scientists that study climate change.

La Nina To Affect Our Winter
October 25, 2007

It is apparent the La Nina conditions are returning and will be affecting our weather through the winter and perhaps into spring. Now don’t panic, all that means is that our winter forecast is for temperatures to be a little warmer than average, and precipitation will be near normal or slightly below normal for December through February.

La Nina occurs when the Pacific Ocean water near the equator is cooler than normal. The opposite of this is El Nino, which occurs when the water is warmer than normal. This change in water temperature has an effect on pressure patterns, which in turn affects the jet stream patterns, which then can impact our weather.
Take a look at these graphics. The first one shows the average jet stream pattern in an El Nino year. Notice how the jet stream is strong coming in off of the Pacific Ocean, bringing systems across the southern United States.

This type of pattern can result in above normal rain for our area. Now take a look at the jet stream pattern during a La Nina year. The jet stream is more variable and can be more amplified. This can mean less precipitation for the southern Plains, as well as warmer than normal temperatures.

That’s not to say we will be wearing short sleeve shirts all winter. Trust me, there can still be some cold outbreaks that affect Oklahoma during a La Nina year.

So based on a strengthening La Nina, here is the official forecast from NOAA for December through February.

Again, use this information with a grain of salt. I still expect a few periods of very cold weather, along with some sleet/ice/snow. In other words, a typical Oklahoma winter. However, in the end our temperatures may average out a bit warmer than usual, with precipitation close to normal or slightly below.
