We have recently had some warm weather with highs temperatures near 40 degrees. I wanted to go back and compare how our highs so far this January compare to last January. The chart below shows the high temperature comparison for Waterloo.

Thursday Night: Cloudy with area of fog and 60% chance of rain. Low: 34-37. Wind: S 5-10 mph
Friday: AM: Mostly cloudy with a 20% chance of rain. PM: Decreasing clouds. High: mid 40s.

Sunday: Partly cloudy. High: low 20s.

Tuesday: Mostly sunny. High: near 30.
Wednesday: Partly cloudy. High: low 30s.
It has been another day with sunshine and high temperatures in the 30s and 40s. More snow and ice melted today and it will again Thursday through Friday. In addition to the warm weather…rain is expected. That combination will get rid of a lot of snow. Right now the cold air is north of the jet stream and out over the Pacific Ocean. The low over Texas is forecast to bring us rain Thursday.
By looking at the satellite image below…the structure of the clouds is a good indicator of the cold temperatures.
Tonight the sky will be mostly clear and the wind will be light. Put that together and moisture in the air from the melting snow…some locations will have fog late tonight.
The clouds will increase Thursday morning and the wind will increase from the southeast. This is all as low pressure tracks north and northeast. Rain is expected to move into eastern Iowa, from the south, around lunch time. Rain is forecast to be on and off through Friday morning before it tapers off. Thursday night the wind lightens up and it will remain warm with light rain. At this time areas of fog may form.
Rain amounts from this storm will be mainly 0.25-0.50” with isolated higher amounts along the Mississippi River. The map below is the rain forecast from Wednesday evening to Friday evening.
Friday will be a bit interesting. I am leaning toward some clearing of the sky to see some sunshine in the afternoon pushing temperatures in the mid and upper 40s. If the clouds hold together through the afternoon the highs will be cooler, more like upper 30s to near 40. A cold is forecast to cross the state late Friday night. High temperatures Saturday and Sunday will be much colder (20s) behind the front. The wind will be strong Saturday but weaken on Sunday.
High pressure will dominate the middle of the country for the first half of next week with dry conditions and relatively light wind. High temperatures will slowly warm back into the low 30s Tuesday and Wednesday. It will now be easier to warm up during the day since there will be a lot less snow on the ground due to the recent warm weather and rain.

From NWS
1987: A winter storm affected the southeastern half of Iowa from late on January 8th into the morning of the 10th. Snowfall accumulations were generally only in the 2 to 5 inch range, but it was the first significant snowfall of the winter in southeastern Iowa and caused widespread traffic problems and a high number of car accidents with dozens of injuries. Reported storm total accumulations ranged up to 5.0 inches at Bloomfield and Keosauqua, 5.5 inches at Keokuk, and 6.0 inches at Oskaloosa.
