Weather pattern changes to milder conditions next week

While we have dealt with plenty of cold air over the past few weeks, things will be turning around from a temperature standpoint next week. High pressure over eastern Iowa this weekend will slowly shift southeast of us into southern Illinois and eastern Missouri. When high pressure is located there, we tend to get warmer. We should go well into the 30s on Monday with the chance of a few 40s not out of the question for Tuesday. No precipitation is anticipated either day, and only small chances exist later in the week.

Dry weekends have been hard to come by

This weekend will be dry, but not because there’s no active weather going on anywhere. A strong weather system will be passing well to our south, throwing only some clouds our direction. Since September 1, five of 14 weekends have had no precipitation at the Eastern Iowa Airport and three of those were in September! The last completely dry weekend – not even a trace of rain or snow reported – was November 10-11. Here are the precipitation values for each weekend since the start of September: September 1/2: 0.88”/0.03” September 8/9: 0.00”/0.00” September 15/16: 0.00”/0.00” September 22/23: 0.00”/0.00” September 29/30: 0.17”/0.15” October 6/7: 0.33”/0.63” October 13/14: 0.00”/0.01” October 20/21: 0.00”/0.00” October 27/28: 0.04”/0.12” November 3/4: 0.25”/0.89” November 10/11: 0.00”/0.00” November 17/18: 0.18”/0.00” November 24/25: 0.00”/Trace December 1/2: 0.53”/0.09”

Quieter weather is likely for a while

While areas of flurries or a few light snow showers remain possible tonight, our weather largely stays quiet for the next week or more. One of the somewhat common patterns during an El Niño is a southerly, wet storm track. That appears to be taking shape later this week into the weekend. The other indication is cold for the upper Midwest. Sure enough, over the next week to ten days, our weather remains pretty quiet with occasional cold shots. Nearly all the moisture will stay to our north or south as well. A significant snowfall may occur over the southern states this weekend. This pattern looks like it could go into mid-December. Weatherwise, it’ll be a good weekend for shopping and other events!

December can have rainy days, but they’re not common

While December is known for snowfall, don’t discount the potential for significant rainfall either. The largest daily rainfall in Cedar Rapids in December occurred on December 13, 2015 when 1.82” fell. There are other several dates with over 1.40” of rainfall in one day. The oldest record happened all the way back on December 12th, 1901. There have been only 18 December days since records began in 1892 with a rainfall over one inch. The rainfall event this weekend does have the potential to exceed one inch, depending on the exact track the storm system takes and whether any thunder occurs. It’ll be a cold rain, too, as highs will be stuck in the 30s.
