WEATHER SUMMARY
By HARRY HILAKER,
State climatologist
March 2012 will long be remembered for exceptionally mild temperatures.
Preliminary numbers indicate a statewide average temperature of 51.2 degrees, or 15.3 degrees above normal. The month averaged 2.3 degrees warmer than the typical April and 2.5 degrees warmer than the previous warmest March – 48.7 degrees in 1910.
Daily temperatures averaged above normal on all but three days of the month March 3 through March 5.
There were three days at mid month, the 17th through 189th, averaging more than 30 degrees above normal and every day from the 10th through the end of the month averaged at least 10 degrees above normal.
High temperatures reached into the 80s somewhere in the state on 14 days during March, topping off at 90 degrees at Sioux City and Little Sioux on the 31st. Nevertheless there was a little winter-like weather early in the month with daytime highs in the 20s in some areas on the 3rd and 4th while Estherville reported a low temperature of minus 1 degree on the morning of the 5th.
While the mild weather has been fabulous for allowing plenty of early field work, it has raised tremendous concern for the potential of severe frost damage to some horticultural crops which are developing far ahead of the normal pace.
The typical date of the last freeze of the spring is not until mid-April in southern Iowa to early-May across the north.
Meanwhile, precipitation averaged 1.96 inches or 0.19 inch less than normal.
This ranks as the 56th wettest March among 140 years of records. Precipitation was generally above-normal from southwest, through central, into northeast Iowa, but was well below-normal over portions of far northwest and southeast sections.
Monthly precipitation totals varied from 0.63 inch at Hawarden to 5.49 inches at Bedford. There was some snow early in the month with two to four inches over the east one-third of the state on the 2nd and one to three inches on the 4th in a diagonal stripe from northwest to southeast Iowa.
Kanawha, in Hancock County, reported the most snow with 5.5 inches, while most of southwest Iowa saw only a few flurries.
The statewide average snowfall was 1.6 inches, or 3.1 inches less than normal. This ranks as the 13th lowest March snow total among 125 years of records.
Finally, there were isolated occurrences of severe thunderstorms, mostly involving large hail, on the 19th, 29th, 30th and 31st.
