After 100+ tornado warnings and record flooding of White Lake, the weather in Arkansas is transferring over to a dry pattern.
Today marks the first time in several weeks that we hit the upper 80's. In addition to the warmth, eastbound lanes of I-40 opened up thanks to the flood waters decreasing across Prairie County. Tomorrow authorities may open the westbound lanes and put an end to the massive traffic delays.
As great as that may sound, I wouldn't get too comfortable with the weather outside. Mother Nature does have something up her sleeve later this week. Wednesday night and into Thursday an upper level low will creep in from the northwest. Near the surface, a low pressure system will venture into Missouri and drag a cold front close to us. As the front approaches from the west it will carry scattered showers and thunderstorms into the state. Along with the wet weather, there is a marginal chance of severe weather in Northwest Arkansas.
After the storms, there is a lot of uncertainy when it comes to the weather for the weekend and next week. Long term models like the GFS (Global model) and the ECMWF (European model) are all over the place. One model wants to put us back into a warm, dry pattern while another wants to cut-off an upper level low force it down to the southeast portion of the country. This would giving us cooler air and more clouds even possibly a few showers northeast.
My gut feeling is to side with the drier solution but we'll see how the upper air unfolds in the coming days. Until then enjoy the summer heat.
