Clouds increasing this afternoon ahead of short wave trough currently located across CO/NM this afternoon. Relatively dry sub cloud layer will remain through most of the afternoon, but will moisten up this evening and overnight as forcing improves with the approaching wave. Models consistent with keeping the main QPF axis south of the red river. While instability will be limited will keep mention of thunder mainly south of I-40 tonight as lapse rates will steepen along with decent shear. One or two storms near the Red river will be capable of producing marginally severe hail along with locally heavy rainfall.

Chances will be maintained into Sunday as a surface front moves through. Large differences between the GFS and ECMWF develop by Tuesday with regards to the upper low that moves across the plains.
