Outflow Boundaries

Outflow Boundaries

Hey everyone! I know its been a while since I last posted. I just got back from the NOAA Weather Camp in Washington, DC, where I participated in two intense weeks of weather boot camp.

Before I left, I took a picture of a shelf cloud. This shelf cloud was associated with an outflow boundary.

An outflow boundary (also known as a gust front) is a region of rain-cooled air that separates a thunderstorm from the surrounding air. This boundary of air is a lot like a cold front.

Due to interactions in the atmosphere, outflow can cause thunderstorms to form, but it can also hinder them. It’s a lot like the way tornadoes need wind shear to be able to spin, but hurricanes don’t.  Some things could go just right, and you would see a major thunderstorm. Other times, it may not produce anything.

Fighting The Drought, One Drop At A Time

Fighting The Drought, One Drop At A Time

Drought is slowly closing in on Hernando County, and while we can't reverse it right away, there are things we can do to slow it's advance.

If you look at the image above, you'll see that as of May 31, only 9.79% of the state is drought free. Unfortunately, the heat is only going to intensify as we head into summer, causing the drought to get worse. The lack of significant rain is slowly catching up to us.

To date, my weather station just north of  Brooksville has seen 13.94 inches of rain this year.

With several scorching months still ahead of us, we need to save as much water as possible, and not waste it needlessly.  Hernando County is now at two-day-per-week watering restrictions.   People with even numbered addresses can water on Thursday and/or Sunday, and people with odd numbered addresses can water on Wednesday and/or Saturday.

Comparing temperatures from May 2011 to May 2010 in Brooksville - Updated

Good evening everyone! As promised, here is an update to last week's article regarding average May high temperatures in 2010 and 2011.


As I was looking through the data from my first article, I realized I did not round my numbers properly.


To ensure best accuracy, I am going to correct my data. In my previous article, I said that May 2010 had an average daily high temperature of 88 degrees.

It's been quite a wait but we finally got some good rain in the area.

Here are some photos sent in by Grayson Kamm of some street flooding on Manhattan Avenue in South Tampa. Seems like this road could use a better drainage system.

Grayson sent these in to 10 News around 1:45 p.m. when the first batch of storms blew through the area. Stay safe on your ride home as the second batch of storms pushes through.

 

When Thunder Roars, Go Indoors - Looking At Lightning

When Thunder Roars, Go Indoors - Looking At Lightning

Spring Hill, Florida -- As we come up on Memorial Day weekend, I want to talk about Florida's biggest weather threat, lightning.... 

Many of you will likely be outdoors this weekend, celebrating Memorial Day. Some of you may even go to a local beach. When participating in any outdoor activity, it is important to know what the weather will be like. While major thunderstorms are not expected this weekend, there is still a chance for a few isolated showers and thunderstorms. Already today, showers have popped up across the Tampa Bay Area.

Lightning is Florida's biggest weather threat, although when asked to name a Florida weather feature, you would probably think about hurricanes first. Florida is the lightning capital of America, with the most frequent lightning occurence of anywhere in the world except Central Africa. Because of this, lightning safety is extremely important. Although no place is perfectly safe from lightning, there are steps you can take to protect yourself from being hurt by it.

Meteorologist speaks to Valrico students

Meteorologist speaks to Valrico students

10 news meteorologist Chris Suchan was at Buckhorn Elementary this week to speak with the 5th graders in Kelli Michael's class.

During the presentation, some background on how Chris became a meteorologist was shared, including being in the 5th grade and becoming interested in weather.

The main focus of his presentation was on severe weather and being safety conscious.  Pictures and videos showcasing tornadoes, microbursts, lightning strikes, hurricanes were used to drive home the point on dangerous weather and how it occurs.

A video of the Tuscaloosa, AL tornado was shown as well as a storm chaser in the eyewall of Hurricane Charley from 2004.
