Chasing Later Today

Posted in Severe Weather Forecast, Storm Chasing at 9:48 am by Rebekah

First, my heart goes out to those affected by yesterday’s storms and tornadoes, especially to those in Joplin. This year has been particularly bad for large tornadoes in populated areas, leading to record numbers of fatalities.

Today a surface low is moving into far northwest Oklahoma, with a warm front stretching eastward near the Oklahoma/Kansas border and a dryline that will tighten near the Oklahoma/Texas Panhandle border. Dewpoints are already in the upper 60s, though some of the moisture may mix out a little bit later in the day. There is a trough out west, but not much upper-level support in the Plains. In fact, there may actually be some height rises in the Southern Plains unless we get a little shortwave trough to come through. Instability will be highest along and ahead of the dryline, and shear will be highest along the warm front, of course. The shear is not going to be that great (especially low-level shear), but should be sufficient for supercells should storms form.

I should be available to chase after about noon or 12:30 today, so I’m planning on leaving Norman by 1 or hopefully sooner. My current target area is around Seiling to Enid, but I may head out west on I-40 to Clinton, and evaluate then what I want to do.
