Strong Cold Front Making Progress Into OK/TX; Freeze Possible Many New Areas Thursday Night...

Above is the latest visible satellite picture with an overlay of the surface weather observations. I have highlighted the location of the cold front at the tips of the red arrows.  Behind the front, strong gusty N-NW winds of 20-30 mph with gusts up to 40 mph are common.  I have also circled (in yellow) the thickest portion of a large cloud of dust in West Texas.  The dust has been kicked up by the strong winds, and it will be a windy, dusty night across much of the region behind the front tonight.

Showers and a few isolated thunderstorms have broken out ahead of the front in eastern Oklahoma and extreme Northeast Texas, as shown on the latest radar mosaic image below:

Unfortunately, any rain further South in drought stricken Texas will be isolated and not very heavy in association with the frontal passage this evening and tonight.

Strong winds will subside during the day on Thursday across much of the region, leading to a cold night Thursday night into early Friday.  A widespread freeze is likely (for the first time this season) across southern Oklahoma into northwest and portions of central Texas, as shown on the image below:

Areas within the pink shaded regions are likely to have a hard freeze, while areas within the lighter blue surrounding those regions will be very close to freezing for at least a short time late Thursday night and early Friday morning.
