*Substantial* Severe Wx Threat Christmas DayDecember 23rd, 2012 at 6:01 pm by Matt Barrentine under FOX10 News, FOX10 Weather
While we are opening our gifts Tuesday morning, an area of low pressure will be developing over east Texas, and creating the second system. This low will feed on warm air (60 for a low and 70s for highs Christmas day!) and track eastward across the Gulf Coast. As the system feeds on the warm, moist air the ingredients will come together for a severe weather event. The Storm Prediction Center has areas west of I-65 under a substantial threat for severe weather.
The first storms could start bubbling up near or just after breakfast in the western half of our viewing area. These pre-frontal supercells are often the most dangerous (like the one that spawned Thursday’s tornado in Mobile). These supercells will have the opportunity to form throughout the day while we are in the warm sector of the system.
By the evening hours the front itself will be approaching. The front itself will bring a squall line through. Squall lines are unlikely to have tornadoes, but damaging straight-lines winds will be possible.
Once that line passes and the cold air moves in the threat will end, but from start to end this system could put our area under threat for 12+ hours.
The timing could possibly change, but the threat is there and we will have to vigilant as we watch this system develop. Of course, here at Fox10 we will be tracking all this and keeping you informed in the days ahead.
