KEY MESSAGES

- The next widespread light freeze is expected Monday night into Tuesday morning.

DISCUSSION

Issued at 1232 PM CST Fri Dec 5 2025

Tonight and Tomorrow: A few lingering showers will remain possible across southern portions of the area, nearer a surface boundary that is stalled near the coast. This precipitation and cloudiness will help moderate temperatures nearer the coast where areas further inland will be increasingly seeing dry, continental air filtering in from the north. For this reason, most areas will remain cool and dry through Saturday as overnight lows tonight drop into the 30s F for most and lower 40s F along the highway 84 corridor. Areas along and north of highway 82 will see some risk for a brief freeze just prior to dawn.

Through next week:

The overall pattern will continue to feature a general ridge pattern over the western US and a trough in the east. Locally, this will mean mostly northwesterly flow and reinforcing cool intrusions. Along with this, the troughy nature of the pattern suggests some opportunity for periods of precipitation. The first of which could arrive in the later part of Sunday, featuring a cool or cold rain with limited hazards likely. Following the first wave and front Sunday into Monday, the next round of showers and reinforcing cold front looks likely towards the end of next week when a more robust shortwave moves through the longwave trough. Uncertainty at the 7 day range with an active jet stream suggests there could be shifts in timing or intensity of this activity, but there does appear to be an increased chance for thunder compared to recent activity that has occurred with very limited thermodynamic instability. Some longer term guidance suggest dewpoints could rise into the 60s F ahead of that front which would be probable to support some convective activity were that to be the case.

Otherwise, temperatures this week will generally be near to slightly below normal with highs in the mid 50s to lower 60s F and lows in the middle 30s to 40s F most days with a few opportunities for a freeze on a few of the chiller nights. For now, the coldest night appears likely to be Monday night when most areas see temperatures near freezing with northernmost areas dipping into the middle 20s F. /86/

AVIATION

(18Z TAFS) Issued at 1232 PM CST Fri Dec 5 2025

Widespread low stratus deck is causing IFR conditions at most TAF sites to start the period. Some lifting to MVFR is possible, but chances increase for return to IFR conditions after 00Z Saturday. /NF/
