Oh by the way, the wind from the northwest pushing wind chills into the 20s doesn’t help either. Some locations across northern Iowa had a little dusting of snow this morning. We at least it is Friday.

Tonight will be cold as temperatures drop to the 20s by Saturday morning. Dry weather is expected Saturday with a few rays of sunshine. More clouds than sun should be expected.

As one storm moves away we are tracking another one about to approach the Pacific Northwest. The low is forecast to track across the Midwest on Sunday. A warm front will push east first with rain showers Saturday night in to Sunday morning. There may be a break in the rain late Sunday morning into early afternoon before the cold front increases rain and thunderstorm chances for the afternoon. The map below shows the WPC forecast position of the low Sunday morning.

Ahead of the cold front the wind will be gusty from the southeast pushing highs into the upper 50s and low 60s. Unfortunately colder weather moves back in as the storm moves east. The forecasted rain amounts from Friday evening through Sunday evening will range from 0.25-0.75” in most location (see map below).

Apr 12 QPF
The cold front will stall south of Iowa Monday and Tuesday keeping clouds and chances of light rain in the forecast. As the front stalls, another area of low pressure develops southwest of Iowa. It is forecast to track northeast along the front and bring rain to the area Wednesday and Thursday. The last few model runs show heavy rain (more than 1”) is possible with this storm. Here are the GFS and ECMWF models for Wednesday evening.

Apr 12 Wed Eve Models
Once the storm moves away there is a chance of a few snow showers Thursday night…similar to last night. High pressure is forecast to bring dry and cool conditions Friday.

The Climate Prediction Center 8-14 day outlook for April 20-26 has Iowa with below normal temperatures and near to above normal precipitation.

April 12

TodayinWeatherHistoryFrom NWS
1964
: Four tornadoes touched down in southwestern Iowa including an F4 that killed one person and injured 28 others in and around Yorktown in Page County.

 This Day in National/World Weather History …
 12 April 1927 → In Rock Springs, TX an F5 tornado struck, killing 74 people and causing $1.2 million in damage. Out of 247 buildings in town, 235 were destroyed. The tornado was more than a mile wide and moved from northwest to southeast. The tornado was part of a much larger outbreak spreading from the Plains into the Ozarks, and was on the second day of a four-consecutive-day stretch of tornado outbreaks in Texas.
 12 April 1934 → Winds atop Mount Washington, NH averaged 186 mph for five minutes, with a peak gust of 231 mph.
 12 April 1945 → Despite Antlers, OK being hit by an F5 (estimated) tornado that destroyed 600 of the tiny town’s buildings and killing 69 people, newspapers barely mentioned it. President Roosevelt had died three hours earlier.
