DISCUSSION

Issued at 1145 AM CDT Fri Oct 9 2026

An amplifying ridge across the Great Plains into southern Canada keeps the summer-like temperatures in place this afternoon. Temperatures climb into the mid-80s across the region under mostly sunny skies. These temperatures are approximately 15 degrees above normal for this time of year and just shy of record territory. Wind speeds will gradually increase later this afternoon as the surface pressure gradient begins to tighten as a trough digs across the Pacific Northwest. With the increasing south winds, temperatures remain milder tonight, hovering in the 60s across the area through Saturday morning.

Saturday will be the warmest and windiest day of the forecast period. The low-level thermal ridge and pressure gradient continues to strengthen and tighten as a large trough digs over the West Coast and as Hurricane Isaias makes landfall in the Southeast. As a result, south winds increase in speed with peak afternoon gusts of 30-40+ mph likely. High temperatures climb into the upper 80s to near 90 across the area. Several records may be challenged across the region with these expected temperatures. Norfolk's forecast high temperature is 89 with a previous record of 87 set in 2024. Omaha's record of 88 set in 1963 may be challenged with a forecast high of 89. Lincoln may fall shy of their record high of 91 set in 2024 with a forecast high of 87. In either event, these temperatures are reminiscent of mid-Summer rather than Fall.

In addition to the Summer-like heat and windy conditions, dry weather develops. Afternoon minimum relative humidity plummets to between 20-40 percent across the area. The strongest winds and lowest relative humidity is forecast over northeast Nebraska. An elevated fire weather threat may develop, especially since this region missed out on the majority of September's rainfall.

Temperatures and wind speeds begin to decrease on Sunday as the pressure gradient begins to slacken and low-level thermal ridge shifts east. Summer-like temperatures continue despite this with highs in the low- to mid-80s in the forecast once again. Thankfully, a cold front arrives early next week, beginning a cooling trend for the region. High temperatures in the 70s begin to return to the forecast on Monday and for all by Tuesday.

Our next weather system is set to impact our weather by the middle of the week. A trough is expected to eject into the Great Plains and interact with remnant moisture from Hurricane Simon. Ensemble guidance is in relatively good agreement that beneficial rainfall can be expected with this system. Widespread rainfall totals between 0.5"-1" appear likely at this juncture. This weather system is expected to remain progressive with another cold front pushing through the region by week's end. Surface high pressure and Fall- like weather should return to the forecast by next weekend.

AVIATION /18Z TAFS THROUGH 18Z SATURDAY/

Issued at 1145 AM CDT Fri Oct 9 2026

VFR conditions are expected through the TAF period. Light winds gradually become southerly and increase in speed through this afternoon. A strong low-level jet develops after sunset this evening. 40 to 50 kt winds aloft overspread the region within this low-level jet. LLWS is forecast to develop between 02Z to 05Z tonight across the region as a result. After sunrise, vertical mixing helps to increase wind speeds further as the strong winds from the low-level jet get mixed down. LLWS will dissipate as surface wind speeds increase. Peak afternoon wind gusts between 25-35 kts may be possible during the afternoon on Saturday.
