NEAR TERM

(Today) Issued at 313 AM CDT Sun Mar 29 2026

Surface high pressure centered over the mid Atlantic will be the primary influencer for local weather today. On the westered periphery of said surface high pressure, ESE surface flow is currently being observed. Through the day as high pressure slowly pushes east, winds will shift to the SSE, maintaining our slow but much needed moisture return. As such, dew points are forecast to gradually increase throughout the day keeping min RH above critical levels and mitigating yesterdays Red Flag Conditions. Even so, it will still be dry and windy with gusts up to 25 MPH through the morning. Thus, caution should still be used with any open flames or sparks. Under mostly clear skies, temps will rise into the high 60s to low 70s before another cool night in the low 50s.

SHORT TERM

(Sunday night through Tuesday) Issued at 947 PM CDT Sat Mar 28 2026

The dry weather pattern will continue through the early part of next week. A zonal upper level pattern across the Southern CONUS takes shape as we begin the upcoming work week. WAA begins to increase starting Monday as southerly flow will also increase the moisture return off the Gulf. Temperatures will warm into the mid to upper 70s on Monday and then the low to mid 80s on Tuesday. With dewpoints returning to the 50s on Monday and perhaps near 60F on Tuesday, it will start to feel more like late Spring/early Summer airmass. Overnight lows will begin to warm as well with Sunday night temperatures in the low to mid 50s and then mid to upper 50s by Monday night.

LONG TERM

(Tuesday Night through Saturday) Issued at 947 PM CDT Sat Mar 28 2026

A pattern change begins to take shape the second half of next week as the zonal flow aloft breaks down and a trough digs southward across the Rockies. A series of shortwaves rounding the base of the trough axis will help create a wetter pattern across the Tennessee Valley. The first of these shortwaves arrives late Tuesday night into Wednesday morning bringing low (20-30%) chances for showers and thunderstorms. Chances increase (50-60%) for showers and storms Wednesday afternoon through Thursday night as the approaching trough to our west pushes a cold front towards the local forecast area. It does not appear at this time that severe storms will occur given the stronger shear lags behind the better instability. Also, with the showers ahead of the front this would also limit any instability to build up when the better forcing arrives.

Another stronger system develops late next week and ejects eastward along the trough axis to our west. As it pushes another cold front into our area next weekend, it will bring medium (40-50%) chances for showers and storms. Ensemble guidance is a bit inconsistent with the timing of this system and therefore the PoPs should trend up when better agreement begins to occur. Based on the latest models, this system would have some better synoptic support compared to the mid week system. Therefore it is something to keep on eye on for severe storm potential. However, this far out a lot can and will change, but what is more consistent in the model runs is that this system could bring some much needed rainfall to the area.

AVIATION

(12Z TAFS) Issued at 652 AM CDT Sun Mar 29 2026

Surface high pressure centered off of the Mid Atlantic coast will bring a southerly flow across the TN Valley into the early week. Winds up to 40kt, 1000-3000kft above the surface continue, thus maintained a Low-Level Wind Shear mention for the start of the TAF. This flow should subside a couple hours from now. Otherwise no weather of significant consequence is expected for the next day. SE winds 5-15kt early this morning should become southerly at 10-20kt in the later morning and this afternoon, then subside below 10kt this evening.
