MESOSCALE UPDATE

Near-term weather elements through the daytime tomorrow were updated with latest guidance, but no major adjustments were made. Overnight lows tonight still expected to range from the lower to mid 20s at most locations. A light breeze and drier air will limit frost development, but temps will still be quite chilly. Lowest wind chills around sunrise will range from 15-20 degrees, so be sure to bundle up if outdoors in the early morning. /NF/

DISCUSSION

Issued at 146 PM CST Mon Dec 29 2025

The much talked about Arctic cold front made its way through the area last night and behind it our temperatures have taken quite the dive. Highs across the CWA will range from 40F in the far northwest to 50F to the far south. A stark contrast to yesterdays observed highs of around 80. Temperatures will continue to tumble tonight, combined with gusty winds wind chills looks to range in the teens, so bundle up!

Continued northerly flow will continue through New Years Eve (Wednesday) when winds are expected to shift westerly, and maintain that general component until this weekend when onshore flow is expected to return to the region. As such more seasonal temperatures are expected for New Year's hovering in the upper 30s around midnight. With more moderate wind speeds expected, wind chills are not expected to significantly affect the apparent temperature. It should be noted that we will continue to monitor fire weather threats as we near celebration time, since we really haven't had a good wetting rain in a while. At the moment humidity values are projected to be well above any notable thresholds, and wind speeds too low; never the less a watchful eye will be maintained for any potential moving forward, given the typical festivities.

The new year will see a return to southerly flow and thus a rebounding of high temperatures into the mid 60s to finish out the period and lows around 50F.

This weekend could see yet another wave make its way through the area, at the moment it looks like this will produce a bit more rain than the FROPA we had yesterday, and also should not crater our temperatures as significantly either. /OAJ/
