DISCUSSION

Issued at 308 PM CST Sun Jan 11 2026

Through Monday: Latest surface analysis had a dry reinforcing cold front nearly along Interstate 20. Satellite Imagery/RAP analysis showed northwest flow aloft that is progged to continue through Monday. This will help the cold front push south of our CWA by this evening. A >1034mb high will continue building over our CWA from the northwest in wake of the cold front. This will bring in a cooler and even drier airmass to our region. The gusty north wind this afternoon will subside by this evening and under strong radiational cooling tonight temperatures will bottom out in the mid 20s to near 30 degrees. Monday the surface high will become centered over our CWA and weaken resulting in a much lighter wind than today. Temperatures will top out in the lower 50s which is slightly cooler than normal. /22/

Monday night through Saturday night: Cool and dry northwest flow aloft will be the primary weather influence this week, but expect a few temperature swings as a couple of polar air masses will be poised to surge into the area late this week and again next weekend. Ultimately, the bulk of guidance indicate a brief warm up for Tue-Wed, followed by a more significant surge of cold air for Wed night-Thu night that should have temperatures a good bit below climate normals. Another brief warm up should take place Friday ahead of the next polar air surge over the weekend. Guidance shows a good bit of variability with just how intense the cold will be, but it will be something to keep an eye on in terms of impacts. As has been discussed recently, winter weather threats remain low for the long range forecast with the bulk of guidance not timing moisture/cold well enough for any wintry precip. /EC/
