UPDATE

Issued at 957 AM CDT Fri Apr 24 2026

A quick update to adjust POPs across the region. Decided to decrease rain chances through this afternoon, as it appears the bulk of the precipitation will hold off until the late afternoon/evening time. Currently, we have a decaying line of convection ahead of a cold front across Northern and Central Arkansas, which extends back westward into eastern Oklahoma. Later today, redevelopment is expected along the cold front as it continues to slowly push southward into our region. At that time, severe weather will become a threat, as cluster of convection is expected to dive south into the region. With deep layer shear between 30-40 kts, MU Cape values over 3000 J/Kg, steep lapse rates, and decent 0-1 KM SRH, expect all modes of severe weather to be in play. /20/

KEY MESSAGES

Issued at 1233 AM CDT Fri Apr 24 2026

- Upstream convection across the Southern Plains and Ozarks will help reinforce a cold front southward into the northern parts of our region later today.

- Warm and moist southerly flow ahead of the front will promote strong instability across our region this afternoon into the evening with an expanding severe threat during this timeframe.

- This active weather will continue through this weekend as the cold front stalls and retreats back northward on Saturday with additional rounds of severe weather likely into early next week.

DISCUSSION

Issued at 1233 AM CDT Fri Apr 24 2026

As referenced in the key messages above, a very active stretch of weather is expected to unfold over the next several days after a rather uneventful start to spring severe season up to this point. Starting today, expect a cold front to approach from the NW later this morning along ongoing upstream convection which will only help to reinforce the front southward. Looking aloft, an embedded shortwave trough will further enhance convection by this afternoon and into the evening hours as the sfc front shifts farther SE into our region. Along and ahead of the front, convection is expected to become widespread as it enters our NW zones along and north of I-30 with additional SE progression expected along and south of I-20 through the evening and overnight hours.

Sfc-based instability is expected to peak around if not exceed 3000+ J/kg while mid-level lapse rates will average near 8C/km later today and into the early evening hours. This will support rapid upscale growth of thunderstorms, allowing for a very broad area of potential severe weather from the Ozarks well south into our entire region from this afternoon through this evening and overnight. Damaging winds will be the more expansive/predominant threat, especially with a linear storm mode that appears likely and possibly coming in multiple waves as indicated by several of the hi-res CAM solutions. In addition, veering low-level flow ahead of the front will promote gradually increasing deep-layer shear such that individual storms are likely to pose a threat of large to very large hail along with a few tornadoes, especially over the western half of our region (roughly along/west of I-49) as highlighted in the SPC Day 1 convective outlook. The severe threat is likely to extend through at least midnight, especially along and south of I-20 before diminishing areawide into the wee hours of Saturday morning.

As we move later into Saturday, the cold front will stall invof of I-30 and eventually lift back northward throughout the day. As a result, warm and moist air advection will resume areawide and provide the set-up for additional rounds of severe weather as another series of upper-level disturbances shift through the W/SW flow aloft this weekend. As these disturbances interact with an increasingly warm and unstable environment, expect the next round of severe weather to occur in a similar timeframe by late Saturday through early Sunday, mainly across the NW half of our region. Like the first round, expect all severe modes to be in play with damaging winds and large hail being the primary threats.

Beyond Sunday, the forecast still appears very unsettled as the next cold front will struggle to make much southward progress into our region by early next week. This is largely due to a strong and expansive upper-level ridge just to our S/SW that is expected to remain anchored across northern Mexico and much of the western Gulf through the middle of next week. Coupled with an increasingly active SW flow pattern developing by mid to late next week across our region, we could be in store for repeated rounds of additional severe weather and heavy rainfall. For now, the focus is largely on today and tonight into this weekend with an eye to next week as we close out what looks to be an active last week of April.

AVIATION

(12Z TAFS) Issued at 510 AM CDT Fri Apr 24 2026

Currently dealing with a mix of MVFR and low VFR ceilings across our airspace early this morning. Our airspace has remained convection free thus far but that will be changing as we go through the day and especially overnight. Outflow boundary resides just north of our airspace attm and as that boundary sinks southward and encounters daytime heating, it will become a favored area for strong to severe thunderstorms. Have continued to try to trend TAFs with an HRRR/HREF blend when it comes to the progression of that boundary and convection into our airspace later this afternoon through the evening and overnight hours. Look for SSW to SSE winds sustained near 8-12kts with higher gradient gusts with much stronger convective gusts expected later today through tonight.
