Warm front continues to push north from the Gulf increasing cloud cover and rain potential as we move into the overnight. Some areas within the extreme western Big Bend have already begun seeing light showers activity. This warm front will begin to blanket over the area tonight featuring wide spread light to moderate showers with a few isolated downpours through Sunday night. We will see a brief clearing fro Monday afternoon but quickly developing colds by Monday night with rain chances at 20% Tuesday. This is due to two developing upper level lows situated within the Ohio River Valley and the other centered around the Texas Panhandle. Between the two lows, a trough will deepen creating a decent cold front. Models do indicate a warming trend to the low 70s by Wednesday afternoon through the rest of the seven day outlook. With warmth comes lift and this is a major key component in producing thunderstorms. The Front/low pressure system combination will takes its time passing through the Southeast taking Tuesday night, 30% chance for rain, into Thursday, a 40% chance for rain, to finally pass over with the more active weather falling on Thursday afternoon. This is where we will have the best potential for isolated thunderstorms and popcorn showers. The Severe Weather Prediction Center has not indicated a chance for severe weather as 3PM this afternoon and it looks like the environment over the Big Bend will still be too stable for severe weather on Thursday. However, the Storm Team will continue to monitor the mid and upper levels for any changes and bring you the latest. By Friday we will see more sunshine than cloud cover with rain chances keeping to 20% or less into the weekend. Lows will rebound from the low 40s to the low 50s by Wednesday morning and hold through the rest of the outlook.
