February Weather Discussion. Wild Winter Storms?
Next week we should have a couple light freezes. Looks like a dry northwesterly flow sets up next week. After that some models show a cross polar flow, still uncertain if this will come true even if it does climatology starting to be against us for true artic air this far south.

Looks like more interesting wintry weather may be ahead for TX later next week. AO, NOA, (severely negative) and a rather robust +PNA ridge is suggested by the OP as more strongly suggested via the ensembles. A very strong late winter Arctic front will pass through TX Sunday/Monday ushering some very chilly temps. There are strong suggestions that a cross Polar flow will become established later next week. The GFS has suggested a 1082mb Arctic High building which is extremely unusual. We shall see, but the ECMWF suggests a rather strong storm will dive into the region near Thursday/Friday next week with some very chilly air and more wintry precip for TX.

Randy started this Topic first, so we will let this one cover the next "threat".

This is from a clipper type system digging very deep around the PV. We will need to see what the later runs show for a 'bigger' storm that has been progged around the 20th +/- a couple of days. Hopefully this will be the last big push of colder air this season, but I would not bet the farm on that just yet with what the ensembles are suggesting.

Whoa...1082 mb???? That's like biblical. Are you referring to the block over Greenland and if so, what hour?srainhoutx wrote:Looks like more interesting wintry weather may be ahead for TX later next week.
