Frosty Weather

9:14 PM Mon, Apr 28, 2008 |


First we had some sleet or small hail today and now we're talking about a frost or freeze tonight.

It may sound like it's late in the season for a frost, so I did some digging. If we hit 32 at Lambert airport it would tie for the 5th latest frost on record in St. Louis. However, the latest frost was on May 10th back in 1966. I checked with the Weather Service today and they said the average last frost for St. Louis is around ...



Air Conditioner or Furnace? From 80s to Frost!

9:02 AM Mon, Apr 28, 2008 |

That's the debate in the Chambers household these days, and I doubt we're the only ones!

Let's do a quick review of our recent rollercoaster ride. High temperatures averaged 78 degrees from Monday through Friday of last week. Factored into that number were our first two 80-degree-plus days of the year (Wednesday, April 23 at 81 and Friday, April 25 at 80). A cold front swept across the bi-state area Friday, bringing a round of stron...



Spotting A Different Kind of Mercury

9:01 AM Wed, Apr 23, 2008 |

No, not the silver-colored goo in thermometers... the planet!

Mercury, named for the swift-footed messenger of the Roman gods, is the planet closest to the Sun. It also happens to be the fastest-moving planet in our solar system, averaging about 30 miles per second as it makes its orbit around the Sun.

Of the five planest that can be seen with the naked eye, Mercury is typically considered to be the most diffi...



Close to 80, but no cigar

5:12 AM Wed, Apr 23, 2008 |

The high temperature Tuesday was 79, which is above the average high of 69, but it means we still haven't hit 80 at Lambert International Airport. Now, I've seen quite a few low 80s on Tuesday from our weatherbug netowrk (links for those sites are in the middle of the weather page here on KMOV.com), but we just can't seem to get to 80 at Lambert. But we're forecasting temperatures near 80 for Wednesday, which could be our first 80 degree or ...



What's Inside Hail?

Another Shake, Rattle & Roll?

3:58 PM Sat, Apr 19, 2008 |


Everyone is asking, "Did you feel the earthquake"? I'm so dissapointed that I slept through it and did not feel the aftershock later in the morning. Oh Well, maybe next time. It turns out there have been more than 10 smaller after shocks, even a few today.

The strongest aftershock today (Saturday) hit around Noon. However, it rated a 2.8 which no one likely noticed except for geologists studying and monitoring the area. Here...



Storms, Flooding & River Levels

3:48 PM Thu, Apr 10, 2008 |

It may be a busy night in the 4Warn storm center. A potent storm system is swinging through the Midwest and will produce several areas of strong to severe storms including the possibility of tornadoes. If the storms do flair up in our area, we'll go into storm mode sending our crews out across the area while Kent and I track the latest storms and provide live updates on KMOV.com and channel 4. While there is a slight risk of severe...



Tuesday Storm Threat

3:23 PM Mon, Apr 07, 2008 |


I just finished looking over some of the new information regarding Tuesday's storm threat. It looks like there will be a slight risk of severe weather across the area, with an increased threat between Noon and 9pm. Before Noon and in the early morning hours a few storms from Western and Central Missouri may still be producing small hail as they weaken and move towards the Bi-state. So, while morning rain and storms are possible, the ...



An Active Week Ahead

3:27 PM Sun, Apr 06, 2008 |

Despite today being a beautiful Sunday, it looks like we have a couple stormy days ahead this week. It's not going to be one of those weeks with a chance of rain every day, but it looks like both Tuesday and Thursday could see storms with a potential for heavy rain.

Tuesday morning a warm front moves in with more moisture which should produce some morning showers and a few storms across the area. But it's Tuesday afternoon that looks...



Rivers Rising

4:41 PM Tue, Apr 01, 2008 |

With recent heavy rains we have several rivers again expecting flooding. Moderate flooding is expected on the Meramec at Eureka and Valley Park as well as on the Mississippi River at Chester. For details on the river levels as well as forecast crests check out this link:

March Madness, Weather-style... A Soggy Record

7:17 AM Tue, Apr 01, 2008 |

When the sun came up on the last day of March, we were sitting at spot #7 on the list of wettest Marches in recorded St. Louis history. But, with more rain in the forecast, and with less than an inch between our monthly rain total and the all-time March record, it was clear that we had a shot at rewriting the record books.

Sure enough, with Monday's total of 1.22 inches at Lambert International Airport, March of 2008 became the wettes...
