Fall 2024 Frost/Freeze Info Page (includes map/tables of average first dates for several locations)

** PLEASE NOTE: This fall, NWS Hastings will issue Freeze Warnings/Frost Advisories for all 30 counties in our coverage area UNTIL those counties experience at least one freeze/hard freeze. After that point, additional Warnings/Advisories are largely considered unnecessary because the growing season has effectively ended. Stay tuned to this page for updates regarding when upcoming issuances of Warnings/Advisories appear possible, and also when Warnings/Advisories will cease for the fall season. 

According to long-term averages, the NWS Hastings coverage area of central/south central Nebraska and north central Kansas is NOW INTO THE 1-3 WEEK TIME FRAME THAT OFTEN (but not always!) FEATURES THE FIRST FALL FREEZE. 
** NOTE: ** parts of especially our northern coverage area (north of I-80) have experienced 1-2 instances of frost so far this fall, but MOST of our area has been frost-free so far, and hardly any location in our area has registered a freeze of 32º. 

As outlined extensively in the data presented below, the first fall frost/freeze dates can vary tremendously from one year to the next, and just within the past 30 years, "first freezes" (32°-or-colder) have ranged anywhere from mid-September to early-November. Last fall (2023) actually featured fairly "normal" dates for the first freeze/hard freeze (see 2023 recap section below for more details). 

Please refer to the wealth of information within the tabs below (including tables/maps of average first frost/freeze/hard freeze dates) to stay on top of the frost/freeze situation across our local area this fall. This includes the "Looking Ahead" section just below, which will highlight any nights within the next 7-10 days that appear to hold frost/freeze potential (if any). Finally, check out the last tab for a glance back at the RECORD-EARLIEST frost/freeze that parts of our area experienced 50 years ago on Sept. 3, 1974!

Looking Ahead...Oct. 9-16   ** Frost and/or Freeze Looking Increasingly-Likely Oct. 14-16 ** 
(info here last updated Oct. 8 BUT WILL NOT BE UPDATED AGAIN UNTIL LATER IN THE MONTH...always visit www.weather.gov/hastings for latest forecasts)

• Oct. 9-13 (Tues night-Wed AM through Sat night-Sun AM): NO APPARENT CONCERN FOR FROST/FREEZE AT THIS TIME
  - Nightly low temperatures will mainly be in the 40s-50s
   
• Oct. 14-16 (Sun night-Mon AM through Tues night-Wed AM):  FROST/FREEZE INCREASINGLY LIKELY FOR AT LEAST PARTS OF OUR AREA 
  - Although there is still some uncertainty in the "finer details", it's looking increasingly-likely that one or more of these 3 nights/mornings will feature not only frost, but quite possibly sub-freezing temperatures across at least parts (possibly most?) of our coverage area.

Recapping Last Fall's (2023) First Frost/Freeze in the NWS Hastings coverage area:

• A Fairly "Normal" First Fall Freeze/Hard Freeze For the 2nd-Straight Year:  As was the case in 2022, the first fall freeze/hard freeze of 2023 arrived at a fairly "normal"/typical time, with the vast majority of local NWS observation sites recording their first occurrences of 32°/28° within 10 days of their 30-year average date. More specifically, the majority of stations dropped to at least 32º for the first time on either Oct. 7th or Oct. 16th, with the first hard freeze of at least 28º occurring mainly Oct. 16th or 27th. As is almost always the case, there were a few slight exceptions to the overall "near-normal" trend, including:
  - 1) Greeley NE did not experience it's first hard freeze until Oct. 27th (this was 17 days later than its 30-year average).
  - 2) Plainville KS barely touched the freezing mark (32º) on Oct 7th (this was 10 days earlier than its 30-year average).

Before continuing on, here are a few definitions...

Frost Frost occurs when there is a solid deposition of water vapor from the air. Frost will form when solid surfaces are cooled below the dew point. An air temperature range of 33°- 36°, along with light winds, is usually needed to initiate frost formation. At least minor damage is possible to plants. One must keep in mind that a frost is not guaranteed if the air is very dry and/or winds are roughly 8+ MPH.   The range of average dates for the FIRST FALL FROST across most of central/ south central NE and north central KS is between Sept. 24 - Oct. 9 Freeze Freeze occurs when the temperature drops to 32°-or-lower. A freeze will damage many unprotected plants, especially if the temperature remains at-or-below freezing for several hours.   The range of average dates for the FIRST FALL FREEZE across most of central/south central NE and north central KS is between Oct. 2 - 17 Hard Freeze Hard freeze (per our local NWS definition) occurs when the temperature reaches 28°-or-lower. This usually means that most seasonal vegetation will be destroyed. In addition, there is the possibility for damage to unprotected outdoor plumbing/un-drained sprinkler/irrigation systems etc.    The range of average dates for the FIRST FALL HARD FREEZE across most of central/south central NE and north central KS is between Oct. 10 - 27

Below is a table focused on the average first dates for reaching particular frost/freeze temperature thresholds. Keep in mind, there is often tremendous variation from year-to-year and between any given location across the area!

Explanation of the following table:

• The first column lists 10 locations in south central NE and 3 in north central KS with long histories of being NWS Cooperative Observer sites (except for Grand Island and Hastings airports, which are automated systems). This is just a small sampling of dozens of official weather stations within the NWS Hastings coverage area, and these sites are generally organized down the column from north-to south.
   
• The second column shows the average date of the EARLIEST FALL OBSERVANCE of 36°, 32° and 28° temperatures during the most recent 30 year period from 1994-2023.
   
• The third and fourth columns reveal the earliest first freeze date and latest first freeze date (32° or colder) over the last 30 years. It is readily apparent that the phrase "average freeze date" is quite relative, as most sites feature a 5-7 week difference between the earliest and latest dates. For the majority of locations, the earliest freeze during the past 30 years occurred between Sept. 13-22 in years such as 2014/1995. On the opposite end of the spectrum, for many locations the latest first freeze of the past 30 years occurred between Oct. 25-Nov. 4 in years such as 1997/1998/2015.
   
• The final column is a recap of LAST FALL (2023), showing the first dates that 36°, 32° and 28° thresholds were observed. A blue-shaded date indicates that the first fall frost/freeze/hard freeze of 2023 occurred at least 10 days EARLIER than the 30-year average, while red-shaded dates indicate a first fall frost/freeze/hard freeze that was at least 10 days LATER than the 30-year average.

A Look Back At The Unusually Early Frost/Freeze Of September 1974:

One of the earliest frost and/or freezes on record in parts of central/south central NE and north central KS occurred the first week of September 1974, as many locations dropped below the freezing mark on Sept. 3rd! Just as a few examples: NWS cooperative observers in Beaver City/Ravenna reported morning lows as cold as 29º. Even in our KS coverage area, Webster Dam fell to 32º. 

A surface weather map (below left) from Sept. 3, 1974 depicted just why such frigid temperatures were observed. An unseasonably cold airmass roared into the region behind a strong cold front. Eventually, surface high pressure set up over the region, creating an ideal situation for a record early freeze. In fact, note the handwritten comment "Record early damaging frosts, corn belt area" at the top of the weather map. The original NWS cooperative observation forms from Gothenburg and Greeley NE are also depicted below. The Gothenburg observer noted "Clear. Froze. Ice. Crop Damage" on the right side of the form on the 3rd. It's also interesting to note that both Gothenburg and Greeley recorded freezing temperatures again just 10 days later on Sept. 13!
