*9:30 UPDATE
The wind field aloft is becoming interesting. For most of the day, winds from the surface up through 500mb (18,000’) have been out of the due south. Subsequently, thunderstorm activity has remained in a convergent zone through central TX and OK. Winds are now displaying a slight kick to the east. Storms that were pushing through Dallas some two hours ago have been moving to the NNE at some 25 to 30 mph.
We’re just now starting to pick up on some lightning over Stigler and Sallisaw, OK. These storms are likely being kicked up by outflow winds from storms to the west. At this point it’s a good bet that the greater Fort Smith area will at least get wet. We’re continuing to monitor developments for severe weather though the strongest storms remain south of the latest batch of convection in an area that is untapped. If this activity holds together it will likely pass by to the south of the River Valley.
We are also now under a Flood Watch which is in effect through Saturday. A training effect of thunderstorms may produce localized flash flooding with amounts as a high as 2-4” of rain in our aqrea. Not to sound like a broken record but, please remember that if in doubt about the depth of a covered road, it’s best to turn around and find another route. Just a foot and a half of swiftly moving water can float your car and just half a foot can knock a person down. Be smart and be safe!
