Possible Severe Weather Tuesday

Severe thunderstorms are possible Tuesday, but incredible heat fronted the headlines this afternoon. This morning, the official low temperature only managed to dip to 69°, which happens to be a new record high, minimum temperature for the date. The old record was 67° from 1999. Additionally, with aid of sunshine, the mercury soared into the 80s, and broke a record high temperature. Officially from Easterwood Field, the high temperature eclipsed 82°, breaking the old record from 1982 and 2002 of 79°. Despite a lack of rainfall and storms today, breaking two temperature records along with 30mph+ winds make for a conversation starter around the water-cooler. Yet, there will be rain and several strong storms in our area soon.

At the moment, an area of low pressure swirling on the lee-side of the Colorado Rockies will be the focal point for generating strong to severe thunderstorms from Texas though the Mid-West. This is the same body of low pressure cranking up the wind here today and tomorrow. Over the next 24-36 hours, the center of low pressure should move out of the Rockies, into northern Oklahoma and towards Missouri. Plus, a cold front will hang back and swing though the Brazos Valley as well as most of Texas tomorrow afternoon. Ahead of this front, the air is much warmer than average, and there is plenty of moisture continuing to stream from the Gulf of Mexico. Therefore, the set ingredients in play, and a dynamic cold front will produce a line of thunderstorms with the possibility of damaging winds.

Aloft, winds at the jet stream level will be so powerful, there will be a possibility of tornadoes here, with a much better chance for tornadic activity in northern Louisiana, Arkansas and western Mississippi. Whats important to know here with the jet stream diagram to the left, the wind at the surface and 30,000 feet above the surface are basically lined up in the same direction. In other words, the tornado threat will be minimal, but any storms that form, have the capability of carrying these stronger winds aloft, and bring them to the surface. Therefore, some of the strongest thunderstorms will likely plow though with winds gusting over 60mph at times. Furthermore, after analyzing the newest data coming in, hail will be possible with a few storms as well. However, in order for hail to form, updrafts need to be strong. In order for this to occur, enough sun need to come out tomorrow to intensify destabilization. 

Overall, timing of this event should be between 3pm and 9pm Tuesday afternoon/evening. Exact Trac pans out the strongest storms slicing though the heart of the viewing area around 6pm. Even before the strongest storms move in, areas of rain will make the roads wet for the evening commute. Make sure to ease up on the roads and give yourself several extra minutes to make it safe to your destination. Following the frontal passage and line of storms, drier, cooler air will begin to seep in. 80° temperatures will take a break Wednesday as more realistic weather for this time of the year will settle in for a few days. Also, low temperatures Wednesday night could slide down into the 30s.

This will not be a huge severe weather outbreak, but keep in mind that there will be strong thunderstorms around tomorrow afternoon. Nonetheless, the Brazos Valley will receive widespread rainfall. Most areas will pick up 1/4" of rain with isolated locations picking up nearly 1" in stronger storms. 

I will make sure to keep you up to date as storms erupt.
