KEY MESSAGES

-Mild and dry weather continues through the next few days with high temperatures reaching the mid 60s-low 70s today.

-Weak cold fronts passing through the area on Monday and Tuesday end our modest warm-up and drop high temperatures back down to the 50s-mid 60s for Tuesday and Wednesday.

-Potential for patchy fog has trended down and is unlikely to form outside of a few localized, low-lying areas south of Hwy-136.

UPDATE

Issued at 309 AM CST Mon Nov 9 2026

Much like last night, underperforming relative humidities have again decreased fog potential and the formation of fog outside of a few low-lying areas south of Hwy-136 is unlikely. A slight ridging pattern over the Plains with consistent northwesterly flow in the mid and upper-levels brings another mild and mostly clear day. High temperatures are forecast to rise into the upper 60s-low 70s however, a low pressure system in the Canadian prairie will bring a weak cold front through the area sometime in the mid-day/afternoon hours which could lead to underachieving high temps. The most recent model runs have brought the cold front through the area earlier than previous forecasts which has trended forecast highs down into the mid-to- upper 60s with only our furthest southern portions touching the 70s. The pressure gradients remain diffuse through Monday so winds remain light despite the frontal passage. With the light winds and mostly clear skies low temperatures will sink to the upper 30s-low 40s overnight.

The slight ridging strengthens over the Rockies on Tuesday with an embedded shortwave moving through the Plains strengthening the upper-level northwest flow. As the shortwave passes through, 500 mb positive vorticity advection provides some synoptic ascent which leads to the creation of upper level clouds on Tuesday. A surface low moving across South Dakota brings another weak frontal system through the area on Tuesday which leads to another slight decrease in high temperatures to the upper 50s-low 60s. Following the front the pressure gradient sharpens slightly leading to more breezy northwesterly winds in the 10-15 mph range overnight into Tuesday. These slightly stronger winds coming downslope from the high plains will keep low temperatures slightly warmer than the previous night, staying in the low-to-mid 40s.

Into Wednesday, the ridging holds over the Rockies as the shortwave deepens into a more pronounced trough over the Great Lakes/Ohio Valley region keeping roughly the same mid and upper level northwest flow from Tuesday. The pattern of weak synoptic descent and mostly clear skies returns over the Plains. The synoptic pattern over the plains stays roughly the same as Tuesday which leads to similar highs in the upper-low 60s. Additionally, the pressure gradient remains around the same which brings another breezy day with northwesterly winds peaking in the 15-20 mph range that could gust as high as 25-30 mph.

DISCUSSION

Issued at 1231 PM CST Sun Nov 8 2026

It is a beautiful fall day, thanks to the weak synoptic descent amidst northwest flow aloft, with a digging trough over the Great Lakes region and a weak ridge building over the Rocky Mountains. Clear skies, aside from some high- level cirrus clouds potentially drifting into the northern potions of the area, and modest dew points in the upper 30s to low 40s will allow high temperatures to climb into the upper 60s to low 70s this afternoon. Calm winds will gradually become more southerly this afternoon and evening as a high pressure center in the Southeast continues to dictate the low-level flow.

Fog is again possible tonight into tomorrow morning, as weak winds overnight combine with efficient radiative cooling. Recent REFS guidance currently depicts a 30-60% chance of visibilities dropping below 1 mile tomorrow morning, with this fog potential mainly confined to low-lying areas along and south of Highway 136. Low temperatures are expected to fall into the upper 30s to low 40s by tomorrow morning.

The warm, dry weather is expected to continue through the start of the work week, as the flow aloft remains west-northwesterly. Winds will generally be out of the west to northwest tomorrow afternoon, helping support high temperatures peaking into the upper 60s to low 70s. Fog is again possible (roughly 40-70% chance) tomorrow night into Tuesday morning. However, its development will be hindered by the westerly surface flow, potentially reducing dew points low enough to not reach saturation despite the efficient radiation cooling under the clear skies (similar to what happened last night). A shortwave trough will pass over the region Monday evening through Tuesday, supporting an area of low pressure to the east of the area. While this wave is not expected to bring precipitation to the area, it will bring high temperatures back into the 60s Tuesday and Wednesday. Wednesday will see gusty northerly winds in the wake of a cold front Tuesday night.

Overall, models are in general agreement that a ridge will develop over the Intermountain West and a trough feature will reside over the Midwest/Ohio Valley. However, there is still some disagreement in there these features set up, causing a large temperature distribution in both the NBM and LREF. The GEFS (and parent GFS recent run) still place this trough slightly more to the west, with more shortwaves embedded within this flow, supporting the cooler end of the range (highs in the low 50s). On the contrary, the ENS (and the most recent run of its parent ECMWF model) continue to show this trough moving through slightly quicker, placing it further to the East. This eastward placement would allow the warmer end of the spectrum (highs in the upper 50s).

AVIATION /18Z TAFS THROUGH 18Z TUESDAY/

Issued at 1120 AM CST Mon Nov 9 2026

For KGRI/KEAR Airports:

VFR conditions with clear skies are expected through the TAF period. Winds will stay near 5 kts and be predominantly from the north from 22z this evening through 12z Tuesday morning, and from the south after 16z Tuesday morning. A few hours of VRB will mix in this afternoon and mid Tuesday morning. No gust or LLWS concerns.

While latest thinking is that fog will NOT be an issue at KGRI, we'll keep an eye on trends in the 11z - 15z timeframe Tuesday morning for potential fog along the Platte River valley in Grand Island. There is some fog discrepancy in the 12z high-res models, and given lack of last night's fog, leaning a similar story for tonight.
