Issued at 459 AM CDT Fri Mar 20 2026 Updated Aviation discussion for the 12z TAF issuance. && .DISCUSSION... Issued at 1254 AM CDT Fri Mar 20 2026 Temperatures will be feeling more like late May than late March the today through the weekend. The extreme H5 ridging over the southwest CONUS will continue to flatten and expand eastward into the Midwest today through this weekend, with the highest temperatures forecast on Sunday. High temperatures today and Saturday will generally climb into the lower to middle 80s. On Sunday, temperatures at 850 mb will rise to about 15-18C across the region, which is at the 100th percentile compared to climatology. This will bring forecast high temperatures in the middle to upper 80s. In fact, Sunday's high temperature forecast could be a bit too low still across the Ozark Foothills. Here, the NBM ensemble shows a 50-75% chance of high temperatures over 90F and a 15-25% chance of high temperatures over 95F! Record high temperatures will be challenged daily through Sunday, but they could be broken by a few degrees on Sunday. Sunday evening, a potent but moisture-starved cold front will sweep through the region from north to south. This will bring a small chance (15-30%) of showers and thunderstorms to locations near and east of the Mississippi River, but the setup does not look promising for much in the way of appreciable rainfall. Likewise, any severe weather risk will be confined well east of the region. Following the passage of the cold front, cool Canadian high pressure will bring a major cooldown. However, temperatures Monday through Wednesday will actually be near typical late March values. As the surface high shifts east of the region, southerly return flow will increase, bringing another warmup for the latter half of next week to 10-20 degrees above normal by Thursday. Another cold front associated with a progged surface low passing through the Great Lakes looks to bring another chance (25-35%) of showers and thunderstorms by Thursday night and possibly beyond, but details are murky at this time. && .AVIATION /06Z TAFS THROUGH 06Z SATURDAY/...
