Storms and Cool Weekend Ahead

The storm system currently affecting the state will start to slowly move out of the region by Saturday. Today (Friday, Oct. 13) will be a cool, raw day for most of the state with highs not getting out of the 40s for areas west of Highway 81. Rain will still be likely across most of northeastern and east-central Nebraska through the afternoon, but amounts should be in the 0.10-0.25-inch range. The biggest issue today, though, will be high wind speeds, particularly between Highway 83 and Highway 281, where winds could gust over 50 mph at times.

Saturday, Oct. 14 will be a slight improvement over Friday with a bit lighter winds and some clearing. But it will still be on the cool side with most of the state staying under 55°F and some parts of north-central and northeast NE won't hit 50°F. Parts of far southwest Nebraska may sneak up closer to 60°F on Saturday.

Sunday, Oct. 15 will be a bit warmer than Saturday and should feature sunshine for everyone and lighter winds. A light freeze is certainly possible for much of the western half of the state on Sunday morning and again on Monday morning, Oct. 16. Current forecast is for most of east-central and southeast Nebraska to remain above freezing for minimum temperatures during this period, but there is a chance of it being colder than currently forecast if winds can go near calm.

Typical Fall Week

Most of the next week looks fairly typical for our region of the country in mid-October. Temperatures should moderate to more seasonal levels on Monday and Tuesday, with temperatures over 70°F likely in the Panhandle, southwest, and possibly as far as east as Lincoln in the southern half of the state.

A cold front will move through the state Tuesday night into midday Wednesday, Oct. 18, which will bring rain chances for most everyone. At this time, it looks like a short-lived event with most places not picking up more than a 0.25-inch, and some places won't get anything. Temperatures will cool back to the 50s on Wednesday and Thursday, Oct. 19, before moderating back into the seasonal 62-70°F range by the weekend. Right now, the weather appears to be very nice for the football game.

Beyond next week, it appears our area will be under the influence of more upper level ridging, which should keep us on the dry and seasonally warm side.

Soil Moisture and Vegetation

The latest SPoRT LIS map from late yesterday (00Z 12 October) shows that most of the state was below the 30th percentile, though I think it might be overdoing the dryness in western NE. Regardless, root zone soil moisture has improved since the beginning of the month for a broad swath of eastern and south-central Nebraska. This is good news for next year's winter wheat crop. The plus of having soils be on the drier side is field work can be resumed more quickly after an inch of rain this year than it would have in say 2018 and 2019 when we had surpluses for most of the state.

A quick peek at the rangeland specific VegDRI map shows that pasture conditions are mostly in good shape west of the 100th meridian. Conditions are a bit poorer in central Nebraska but generally showing just abnormal dryness. Exception to this can in Loup, Garfield and Valley counties where there are pixels with more stress. This overlaps well with the U.S. Drought Monitor.

Season's First Freeze

With the first decent blast of cool air this season late last week brought the first light freeze for a large portion of the state. Temperatures managed to drop to 28°F across most stations in the western third of the state, with a few readings in the 22-24°F range in the western Sandhills last Saturday morning. Further east, temperatures weren't quite as chilly, but much of northeast Nebraska managed to drop to 31-32°F briefly this past Saturday and/or Tuesday morning. A few sites in southeast Nebraska also dropped to 32°F last Saturday morning. But much of what I'll classify as the Highway 6 corridor from Hastings to Omaha managed to stay above freezing during the last week.

Some of those sites closer to Hastings are likely to have the first 32°F (or below) reading this weekend, and it's possible the broader Omaha-Lincoln area could drop that low Monday morning if radiational cooling is optimal. But looking ahead a bit, if temperatures stay above freezing Monday morning in east-central Nebraska, we may need to start talking about the possibility of having the latest first freeze on record for places like Lincoln, Omaha and Wahoo.

Crop Condition Update

玉米是成熟为94%(5%分在预算内le). Corn harvest is moving along at 32% complete, which is seven points ahead of the five-year average but one point behind last year. Soybean harvest has accelerated and was 52% complete as of Monday. This is up from 29% last week and six points ahead of the five-year average. Eighty-three percent of sorghum was mature and 18% had been harvested. Winter wheat planting is nearing completion with 91% planted and 65% has emerged. No ratings were given on wheat yet but my understanding is the wheat crop is off to a good start in western Nebraska. Pasture ratings were about the same as last week with 54% G-E and 19% P-VP.
