Late Night Thoughts

The data is starting to shift the mid-week winter weather threat further northward for Wednesday night. However, the onset of the precipitation will cause a big fall in temperatures through evaporative cooling. This could create a setup for a brief wintry mix as far south as Tuscaloosa. Still, the chance for icy spots will be north of Tuscaloosa and mainly along and north of the highway 278 corridor. This would include communities like Hamilton and Cullman. These areas may experience a brief period of snow, freezing rain, or sleet, with most of our area experiencing a very cold rain. To say the least, we will be nervously watching the thermometer Wednesday night.

Special weather statements for icy weather are already up over much of Georgia, where a much colder air mass will be in place. Be sure to stay tuned to the Blog for the latest updates. There will be a fresh discussion linked to our main weather page by 6:00 a.m.

Introduction From Corbin

Hello, my name is Corbin Burns and I wanted to take this opportunity to introduce myself. I attend Northridge High School and I’m currently a WVUA weather Intern. I’m in the tenth grade and I’ve been an intern for over several months. I have always been fascinated by science and the weather. Different kinds of weather really grab my attention. One kind is winter weather and the other severe weather. I’ve always loved to see snow and even ice, but I hardly ever get to see it here in Alabama. Another type of weather that fascinates me is the development of thunderstorms and tornadoes. It’s truly amazing to see their strength and power. I hope that my love for weather will increase throughout the years, possibly enough to let me pursue a career in meteorology. If you’re ever interested in becoming an intern at WVUA please email Wes or Robert.

Monday Afternoon Discussion Update/Winter Weather Possibilities

It’s been quite while since we’ve had a good measurable snowfall over West and Central Alabama. Yet again, this week we are seeing some borderline ingredients coming together for the possibility of snowfall in our area. I know it seems like every time we mention winter weather it seems pan out in other locations over the state, or areas further north. I’ve been delivering weather information for quite some time and I have to say that the most challenging forecasts are pinpointing winter weather in the Deep South, due to the complexity of all the ingredients needed for wintry weather to take place.

Before I begin let me mention that you can find out latest updates here on the blog and I encourage you to check this forum from time to time as we view the latest data and submit our thoughts. For today, the weather has been clear and cold as a northerly flow is in control our weather. A strong 1030 MB high is parked to our west and this is keeping a steady flow of cold air in our direction. Tonight the lows will be near the 30-degree mark in most areas. Tomorrow the core of the surface high will be to our north, near Nashville. This will keep us in a cold weather setup, but the winds will be on the light side.

The forecast gets more complex as we enter the Wednesday timeframe. By Wednesday morning an area of low pressure will take shape in the western Gulf and set a course towards Pensacola Florida. We could see a few cold showers around late Wednesday and then Wednesday night as temperatures approach freezing, there will be the chance for the rain to change to snow. This will mainly be for areas along and north of a line from Aliceville to Tuscaloosa to Birmingham. South of that point we should continue to see a cold rain, possibly with some snow flakes mixing in closer to that line. Temperatures will slowly climb above freezing as the low passes by Thursday and that is when we should see all rain again. The chance for rain however, looks small as the system departs Thursday. Following this system a sharp upper air trough opens the door to a very cold air mass. This will settle into Alabama over the weekend, with highs struggling to reach 50-degrees and lows in the teens for some areas Saturday night.

Let me say again that there will likely be some adjustments in the forecast as we get a better handle on the amount of available moisture and cold air over Alabama. Therefore, stay tuned to the blog and our station for more updates. A small adjustment in the track of the storm system will have a big impact on how much mild air the system will bring with it. Quiet often one ingredient that limits our winter weather possibilities turns out to be the milder air that wraps in with surface lows about 5,000 feet off the ground. If this advection of mild air is on the weaker side, we could certainly end up with a greater possibility of snow. Stay tuned!

Weather Graphic: UCAR plot of the NAM Model, 12 Hour Accumulated Precipitation for Wednesday Night; The morning run of the GFS came in warmer leaning to the side of rain for our immediate area Wednesday night…This may change however, to fall more in line with previous runs. This type of shift happens quite often therefore, as we study the model run to run consistency we will make adjustments in the forecast as necessary.
