Extremely windy conditions across W TX/SW OK today

Very strong to extreme SW winds characterized by an incredible dewpoint depression are expected today, as a result of the main trough crossing the southern Plains. At surface, dryline will rapidly mix from W TX eastwards towards central OK/TX. Deep mixing/lapse rates in the lowest levels will allow the strong mid-level jet (70-80mph at 700mb) to mix towards the surface, which will create extremely windy conditions across much of W TX and later across western OK. Very low relative humidity is expected, likely only around 5% or even lower. Lately, very impressive dewpoint depression was observed along the NM/TX border with T/Td of around 80/-5 which makes RH less than 4%!

This visible satellite shows a large area of blowing dust moving northeast across W TX into SW OK. Wind gusts locally exceeding 50mph are expected!

Further ENE, storms are already on going close the the surface front in northern OK and SE KS. Stay tuned for future updates!
