KEY MESSAGES

Issued at 204 PM CDT Fri Apr 17 2026

- Frontal passage will occur through Saturday afternoon, with a 40% chance of at least 0.75 inch of rain across the area.

- Strong to severe thunderstorms cannot be ruled out, especially through the afternoon into Saturday evening.

- Cooler than normal temperatures return by Sunday into the beginning of next week with a gradual warm-up through the middle of next week.

DISCUSSION

Issued at 204 PM CDT Fri Apr 17 2026

Another period of typical Spring weather will continue for the next 24 hours as the next frontal boundary approaches through the day on Saturday. The severe weather threat cannot be fully ruled out with any background combination of insolation, CAPE, and shear with the lift of a frontal boundary with this intensity in the month of April. A closer look at the severe weather ingredients in the latest short-range model guidance shows mid- level lapse rates of 8 C/km and 30-40 kts of shear being the most plentiful, but a storm mode and arrangement that suggests an isentropic upglide setup for most of the convection that develops through the afternoon into the evening, spatiotemporally undercutting stronger updraft arrangements. Any storms that can form ahead of the frontal boundary have a better chance for stronger updraft formation (and greater intensity) and any large hail/damaging winds as a result.

Rainfall totals of 0.5-1 inch will be common through the area on Saturday, while Day 1-7 QPF values of 0.5-1.5 inches mean the bulk of the rain for this week is also expected to fall on Saturday. Short-range guidance also suggests a concentration of this rainfall along and south of I-20 as showers linger behind the frontal boundary. Post-frontal cold air advection will return for one of the last few times this season on Sunday, bringing temperatures briefly below normal (maximums/minimums in the lower 70s/lower 40s) through the beginning of next week. By the middle of next week, temperature maximums will rebound into the lower 80s once again. Until then, temperatures will remain above normal (maximums/minimums in the upper 80s/mid-60s). /16/

AVIATION

(00Z TAFS) Issued at 645 PM CDT Fri Apr 17 2026

For the 18/00Z TAF period, VFR conditions to begin the period will eventually give way to widespread low stratus streaming back into our airspace overnight through Saturday morning. This will occur ahead of a cold front advancing SE into our NW airspace just after midnight through the early morning hours. A line of convection is expected along the front with the overall coverage and intensity decreasing as the front shifts farther SE toward daybreak. By late morning into the afternoon, heating ahead of the front should help induce some reintensification of showers and thunderstorms so have trended from VCSH early during the morning to SHRA and VCTS later in the period. Cigs will also deteriorate through the latter half of the period with low stratus lingering throughout the day on Saturday along and ahead of the front while convection will also reduce vsbys, especially with thunderstorms and heavier downpours.
