KEY MESSAGES

- Low clouds likely to hang on through today and may linger into Saturday morning, keeping temperatures cool overall.

- A chilly start Saturday with lows near freezing possible if clouds clear overnight, coldest in the typical low-lying spots, followed by a warming trend into early next week with a mainly dry forecast in place.

- Highs climb back into the 60s to near 70 Sunday through Wednesday, remaining above normal for early November.

DISCUSSION

The 00Z Topeka sounding shows a saturated layer from near the surface up through the lowest few thousand feet aloft, capped by a sharp inversion with very dry air above. RRFS, HRRR, and RAP forecast soundings all hold that inversion through this afternoon with the boundary layer still stratus-favored at peak heating, so the deck has no obvious path to mix out from below. Water vapor imagery confirms the dry column aloft with surface high pressure over the central Plains. Northwest flow aloft holds across the area between a ridge over the northern Plains and the trough that exited into the Great Lakes, keeping subsidence and dry air in place above the stratus deck. Any lingering drizzle shifts southeast of the area before sunrise. Cloud cover likely suppresses highs into the low 50s this afternoon and holds lows up early this morning without efficient radiational cooling. Confidence in a cloudy, cool day today is high.

The real question is when the deck breaks, and the answer is not in total agreement among guidance. The RRFS is slow to clear the stratus even into Saturday morning, and the global ensembles show wide spreads on cloud cover, with ENS, GEFS, and GEPS members split between clearing this evening and holding clouds past sunrise Saturday before every member clears by Sunday. The stratus should finally erode Saturday afternoon as the surface high moves east and deeper mixing wins out, but how fast that happens overnight is the uncertainty that drives Saturday morning lows. Clear skies and light winds under the high would bring efficient radiational cooling and lows near freezing, while lingering clouds would keep lows in the mid 30s, so the temperature spread Saturday morning hinges on how much cloud cover remains. Given the overall uncertainty in cloud coverage, a drop into the low 30s is possible but not a slam dunk, with the best chance for a brief early morning freeze in the usual cold spots and no sign of a hard freeze. This is still the first morning worth watching for sensitive plants left out considering the unusual extended growing season.

Sunday through Wednesday still looks quiet and mild. Height plumes climb steadily into Monday with very tight ensemble agreement, placing the area under broad ridging with no meaningful synoptic forcing giving way to near-zero rain chances through at least midweek. Return flow helps to elevate highs into the upper 60s to near 70, well above normal for early November, with lows recovering into the 40s. Confidence in the dry, warm stretch is high given the tight height spread.

The ridge flattens late next week as ensemble spreads widen beyond Wednesday. Ensembles agree a trough digs into the West but differ on its amplitude and on whether a cold front reaches the area by Thursday or holds off until the weekend. Until that spread narrows, the forecast stays with the blend, keeping temperatures mild and rain chances low, with the next real pattern change waiting on that front.

Low-end MVFR cigs dominate the period. Could see cigs drop to IFR at times, especially at KFOE. Clouds may scatter out during the afternoon Friday with highest chances at KMHK. Think MVFR cigs hold for most of the period at KTOP/KFOE. If skies do clear, fog development becomes likely Friday night.
