(Radio Iowa) – State Climatologist Justin Glisan says the initial, long-term forecast for December indicates warmer temperatures and more precipitation, but there’s nothing to suggest there’s an amped up threat of a tornado outbreak like the one two years ago. “December 15th, 2021, that was an extreme event,” Glisan says. “We had a serial derecho and 63 tornadoes — the largest tornado outbreak for Iowa for any month and the largest December outbreak for the United States in the observational record.”

The latest Drought Monitor nearly all of Iowa has some level of drought, with some areas in extreme drought. Glisan says there is the potential for more precipitation to fall in December, but the old adage that it’s too dry to rain is true in SOME cases when thunderstorms hit dry pockets of air. “We saw this in western Iowa as the drought started in May and June of 2020. You would have thunderstorms approach the state and then just either break up or go around because there was no low level moisture to work with,” Glisan says. “Now in these larger scale low pressure systems they’re able to have more access to large scale moisture pools and hence you do see wider spread snowfalls or rainfalls.”

The seasonal outlook indicates abnormally wetter conditions along the southern coast of the U-S and that may provide the moisture weather systems sweeping across Iowa draw from and generate rain or snow.

(Atlantic, Iowa – KJAN) – Weather data for the month of November, 2023 in Atlantic, show the Average High for the month was 54, which was almost 10-degrees warmer than normal. The Average Low was 24, which was 3 degrees warmer than the norm. Rainfall for the month amounted slightly more than one-quarter of an inch (.28″), which was the result of combined rain and melted snow (2.0″). The total liquid value was nearly 1.6-inches below what we would typically receive during the month. The data was compiled at KJAN, the official National Weather Serving reporting site for Atlantic.

Looking ahead, we find the Average High for the month of December, in Atlantic, should be 33 degrees, while the Low should average out to 14. Precipitation (rain & or melted snow) is typically just 1.11 inches.

(Radio Iowa) – There’s the potential for precipitation in southeast Iowa tonight, but State Climatologist Justin Glisan says it’s likely this November will rank among the 20 driest Novembers on record. “The first 20 days we were at 5% of normal, so a very dry first two-thirds of November,” Glisan says. As of this morning, the statewide average for precipitation is just four-tenths of an inch. “That’s almost an inch and a half below average,” Glisan says.

This is the 178th week of moderate drought somewhere in Iowa — the longest drought in Iowa since the U.S. Drought Monitor was launched 23 years ago. “If you combine November with the other meteorological months of October and September, it looks like around the 36th driest fall on record,” Glisan says. “Interestingly enough, last fall was drier. It was the 22nd driest, so you can see that we’ve just really stacked up precipitation deficits through various seasons.” Last spring was the 16th driest on record and this past summer was the 17th driest summer in the past 151 years. “When you’re not getting the expected precipitation in spring and summer, which is the dominant season for rainfall that supplies soil moisture and stream flows, that’s where we’ve seen the drought just expand and intensify,” Glisan says.

The current drought is different from the droughts that struck Iowa in 2012 and 1988, according to Glisan. “This has definitely been longer, but it hasn’t been coupled with extremely warm temperatures for long periods of time,” Glisan says, “so we’ve kind of termed this drought a ‘cool drought’ in that, again, we haven’t seen those exceedingly warm temperatures that would really push drought conditions to lead to widespread crop failure and things of that nature.”

Glisan says there are some positives in preliminary forecasts for the middle of December. “There’s a very high probability of above average temperatures,” Glisan says, “and why that’s a good signal to see is perhaps we won’t see soils freeze as deep or as fast if we have warm temperatures through December.” It means precipitation could be absorbed rather than run off frozen ground.”As you’ll remember from last year, in early December we had widespread rainfall before we froze up that really helped supply moisture for this growing season,” Glisan says. “Also, wetter soils don’t freeze as fast or as deep, so as we get into winter melt into early spring, there’s faster infiltration if we don’t have a deep frost level.”

Preliminary forecasts indicate there are slightly elevated signals for wetter conditions in December.
