DISCUSSION

Issued at 1217 PM CST Sat Jan 17 2026

Water vapor imagery shows a tongue of elevated moisture rounding the base of a deepening trough as a weak embedded shortwave dives through the Red River Valley. Despite this increase in moisture and forcing aloft, the low levels of the atmosphere remain very dry as indicated by our 18Z KSHV sounding. Thus, any radar echoes reflecting light precipitation is virga as it evaporates through the very dry layer of air beneath the mid-level cloud decks. With the increasing cloud cover, the temperature rise has been rather slow thus far with a range of mid to upper 30s along and north of I-30 and mostly 40s elsewhere.

As clouds gradually clear behind the ejecting trough and shortwave later this evening, temperatures will take a nosedive in what will likely be our coldest night so far this winter season. Overnight lows are expected to bottom out in the mid to upper teens in our extreme northern zones through the lower to mid 20s farther south across the remainder of the region. With this prolonged period of several hours below freezing, cold temperature precautions should be made to winterize outdoors for the protection of pets, plants, and plumbing pipes under these potentially hazardous conditions. For all intents and purposes, treat this as hard freeze conditions given the expected duration between 8-14 hours of temperatures below freezing.

Temperatures should climb back above freezing areawide by late Sunday morning with a modest warm-up into the mid 40s to mid 50s by the afternoon under abundant sunshine. Another cold night is in store for Sunday night, albeit not quite to the extent of tonight with a range of mid 20s to lower 30s by comparison. By Monday, a reinforcing cold front will arrive and help maintain below normal temperatures with another areawide freeze on Monday night. Gradual moderation in temperatures will follow by mid-week as southerly winds return on Wednesday. This will coincide with the next trough arrival and subsequent frontal passage on Wednesday night through Thursday. Fortunately, this front will bring increasing chances of very much needed rainfall given our persistent drought and fire weather concerns. We briefly dry out for Friday before additional rain chances return by next weekend with a potentially prolonged period of wet and unsettled weather. More clarity will follow over the next week as the specific forecast details are better resolved.

AVIATION

(00Z TAFS) Issued at 533 PM CST Sat Jan 17 2026

For the 18/00z TAF update...Still seeing some mid to low level clouds filter through the area this evening so have maintained SCT to BKN around 5-10k feet for the next few hours. Thinking that skies will begin to clear from the northwest to southeast through the night with some BKN to OVC high clouds returning closer to morning for most terminals. Winds remain breezy this evening but should relax some during the overnight hours. I do have them coming back up again towards the end of the period for some locations. /33/
