SEVERE WEATHER THREAT
The top half of the week will be quite active as a powerful storm system passes through our area. We’ve had a southerly wind for several days, due to an area of High pressure parked to our east. The wind has been blowing over the Gulf of Mexico; subsequently, lots of moisture has now been transported into our area. In fact, today actually felt a little humid! This moisture is a precursor and important ingredient to a set-up for thunderstorms.
The storm system is pulling in a relatively cold air mass aloft and this will make the atmosphere unstable. Daytime heating coupled with a frontal boundary will provide the lift to fire off convection and due to the turning of the windfield with height; it is likely that rotating supercells will develop. Our threat will mainly be for large hail and gusty winds though there is chance of tornados too. The storm system will likely push through early on Wednesday and there afterwards, we should get break for a few days. We’re monitoring developments closely… keep it tuned to 40/29 on-air and on the web, we’ll keep you advised!
