It snowed in Texas

A big blast of cold air is is continuing to dive nto the High Plains , setting up a fairly chilly end to the week between the Rockies and the Mississippi. We got that that kicked off with this:

The Amarillo WFO would later report 3″ of accumulation, which is a considerable total for west Texas at any time of year, but particularly in October. The snow fell on the back end of an area of low pressure that also swept a very active line of storms as far south as Brownsville, which lead to significantly cooler temperatures in the Lone Star State.

The sharp upper level trough that is serving as a host to this system will also inform as to where the feature will progress. It’s sliding back north in the Mississippi Delta right now, abnd will continue to the Great Lakes. The jet is going to regenerate in place, and at least for the next week, temperatures will be chilly in the Plains and Mississippi Delta, save for a brief warm up tomorrow afternoon.

This standing trough will mean a chilly end to the month east of the Rockies, and a Halloween that requires all the princesses and Iron Men to be bundled up, but it has other insidious consequences. The stalled trough has also led to a strong area of high pressure over the Great Basin, which has fueled the dangerous Santa Ana winds that are fanning the flames around Los Angeles this month.

All that because of snow in Texas. Yeesh.
