DISCUSSION

(This evening through next Friday) Issued at 1210 PM CST SAT DEC 27 2025

The pattern continues across the region as we remain moist but dry and unseasonably warm. The cloud cover may prevent some areas from reaching their highs but most areas are already in the upper 60s to low 70s. Skies will remain cloudy all day so the dreary conditions will continue. Sunday will be a repeat of today.

We finally begin to see a change on Sunday as a strong front approaches the area. Rain should pass through the area rather quickly Monday morning with rain amounts of about 0.25" or less. Severe weather is not expected due to dry, warm mid-level air which will help to stabilize the airmass. With that said winds will be strong to gusty at times along and behind the front, so lose outdoor decorations will need to be secured. By Monday night, temperatures will be down into the 20s area- wide and we'll have a chilly Tuesday with highs ranging from the upper 30s north to mid 40s south. Northwesterly flow will become more zonal by Thursday as low-level ridging builds back over the area. This will cause a gradual warming trend, but temperatures will still remain below normal during that time.

AVIATION

(00Z TAFS) Issued at 520 PM CST SAT DEC 27 2025

Sites have finally broken out of the MVFR. Although it will not last long as most will be MVFR by 4 to 6z. Cigs will lower to IFR 8 to 10z and LIFR at most sites between 10 and 12z. Areas of fog may roll into MGM and AUO so will include some tempo wording here. Regardless, flight conditions will not be very good at all through a good portion of Sunday. Cigs will remain generally in IFR status through 15 to 18z. We will see the clouds mix out to VF after 18z along with winds increasing to 10 to 12 kts with gusts up to 20 kts from the southwest.

FIRE WEATHER

An overall rain-free forecast is expected to continue through the weekend with persisting drought conditions. MinRH values will remain well above critical thresholds for the next couple of days, and 20ft winds will be southwesterly around 5 to 8 kts. A cold front will bring increasing rain chances Sunday night into Monday, but rain amounts look to be less than 0.25". The frontal passage will cause a breezy wind on Monday with a shift to the northwest. Dry air will filter in behind the front and RH will fall into the 30-40% range on Tuesday afternoon.
