Training from surrounding NWS offices:

In March last year, Waterloo had 21 days with the high temperature 60 degrees or warmer. March this year, the highest temperature was 56. Hopefully things will turn around in April. Many of you are looking for spring weather and for it to stick around more than one or two days. There are warmer days in the seven day forecast.

Tonight will be a chilly night as temperatures drop to near 20 by Wednesday morning. Sunshine, a light breeze and highs near 50 will make it feel better than today. Temperatures this afternoon as in the 30s and 40s with wind chills in 20s and 30s.

High pressure will now be east of Iowa and warmer air will return north for the rest of the week. We are tracking a cold front forecast to push through Iowa Thursday with some clouds. It looks like it will come through dry. Here is the WPC forecast map for Thursday morning.

There is another cold front we are tracking and this could bring us a few showers Saturday. Ahead of the cold front a south wind will push highs into the low 60s. Here is the WPC forecast map for Saturday morning.

Apr 2 Sat AM
Even though there is a chance of rain the amount of rain at this point is expected to be low. Here is the rain forecast from Friday evening to Sunday evening.

 Apr 2 QPF Fri to Sun Eve

The weather pattern gets a bit more active as a larger area of low pressure is forecast to bring rain to eastern Iowa Monday and Tuesday. The rain and an east wind will keep temperatures a bit cooler.

The Climate Prediction Center 8-14 day outlook (Apr 10-16) shows eastern Iowa with above normal temperatures and above normal precipitation.

April 2

TodayinWeatherHistoryFrom NWS
2001
: The last of the winter snow pack melted at Sanborn in O’Brien County. This ended an all-time state record streak of 147 consecutive days, beginning on November 7th of the previous year, on which Sanborn had reported at least an inch of snow on the ground. Several other locations in northwestern Iowa had streaks of 138 to 145 consecutive days end during the preceding week. Prior to this the Iowa record for consecutive days with a snow depth of at least one inch had been held by Sioux Center with a streak of 137 days from November 17, 1978 to April 2, 1979.

1982: A sharp cold front moved quickly across Iowa during the afternoon and evening hours. Ahead of the front southerly winds brought warm air into much of the state, especially in the southwest where temperatures peaked at 84 F at Red Oak and 85 F at Missouri Valley. As the front moved through the temperature fell very rapidly, by an incredible 32 degrees in 10 minutes at Red Oak and 40 degrees in an hour at Missouri Valley. Thunderstorms developed along the front further east in Iowa, then snow moved in behind the front creating blizzard conditions in some sections on April 3rd. This ushered in about a week of cold weather that saw several rounds of snow across Iowa, resulting in record April snowfall amounts in some areas.

This Day in National/World Weather History …

 2 April 1982 → Severe thunderstorms touched off 56 tornadoes in the central U.S. An F5 multiple vortex tornado traveled 53 miles from Speer to Broken Bow in southeast Oklahoma. It was the first U.S. F5 tornado after a five year drought.
