It was a cool, crisp morning with lows 48-56.
Today will be a nice with sunshine, a northwest to west-northwest breeze & highs 75-80.
Lows tonight will drop to 52-58 with a rise temperatures possible toward dawn as warm front moves northward & light wind becomes south-southwest & increases to 5-15 mph.
Saturday will be windy & warmer at 82-87 with south-southwest winds 15-32 mph with mostly sunny skies.
Clouds will increase in the evening with a few isolated showers & storms possible (as weak cold front sneaks southward), followed by lows around 60 to the 60s.
Complex of severe storms, originating in North Dakota, will ridge warm front or periphery of record heat developing in the Plains. This MCS will ride southeastward along the front, but should weaken as hot, dry cap overspreads the entire Midwest Sunday afternoon.
The storms may last just long enough for some storms in our northwestern counties & some showers elsewhere before they completely collapse. Severe weather is possible as close as northern Illinois & a bit may sneak into Newton County before they collapse.
Otherwise, we will pick up the convective debri or all of the old cloudiness from the MCS on Sunday, quelling the heat some. Highs in the 80s are expected with a southeast to south wind at 10-15 mph increasing to 15-30 mph.
It appears that temperatures may reach 105 in Nebraska Sunday & that hot, dry air will rise to 5000-8000' & then slide over the unstable, severe storm-ripe sector from South Dakota to Iowa, Minnesota & Illinois. This cap should prevent any storm development, despite explosive environment developing in that zone.
Cap should hold tight through Sunday night over a large area, except Michigan, where an MCS may develop & then pivot through Ontario & parts of the Northeast U.S. Secere weather is possible Michigan to Ontario
Here, front will move well north of us & we will be capped, breezy & quite warm & muggy Sunday night.
Much of the region will be completely capped through midday Monday. It does appear, however, that an outflow boundary from Michigan MCS may begin to pop a couple storms through the cap morning-midday.
Storms are possible late Monday (Labor Day) & then Tuesday. Some severe risk is possible (MARGINAL to SLIGHT parameters) with very warm to hot, muggy weather of 80s to 90 degrees with heat indices of 90 to the upper 90s.
Showers are possible Wednesday as we turn much cooler with highs 68-75.
After highs 67-73 Thursday, we should see a very rapid warm-up again, however. 80s will return pretty quickly after this mid-month cool-snap, but not before the potential of several nights in the 40s.
Unusually cold weather will occur in the High Plains & Foothills of the Rockies. Record heat will be replaced by near record cold. High on Sunday in Denver will be around 100, followed by a high on Tuesday of 41 with rain ending as rain/snow mix & then lows near 28. The unusually cold air will roar down the eastern slopes of the Rockies to the High Plains Monday with gusts to 50 mph at the onset.
Late September to early October will feature a trend of warmer-than-normal temperatures & briefly normal rainfall going below normal.
Temperatures may even go well-above normal in early October here with dry weather dominating.
