A slow moving storm system tracked from the Dakotas into the Ohio River Valley from March 4th through the 6th. This system brought two rounds of snow to the region. The first round hit during the morning of the 4th and dropped up to 3 inches of snow. The second and heavier round, dumped an additional 4 to 8 inches during the evening of the 4th into the morning of the 5th. All together from the two rounds of snow, most of southeast Minnesota received between 5 and 11 inches of snow. The highest reported total was 10.7 inches east of Spring Valley (Fillmore County).

A cold front pushed through the Four State Region during the evening hours of April 27th.  Supercell type thunderstorms developed along the frontal boundary with some hail noted with the storms.  The pre-frontal atmosphere was moderately unstable but cold air aloft was sufficient enough for vigorous updrafts to form and therefore the development of hail.

A cold front pushed through the Four State Region during the evening hours of April 27th. Supercell type thunderstorms developed along the frontal boundary with some hail noted with the storms. The pre-frontal atmosphere was moderately unstable but cold air aloft was sufficient enough for vigorous updrafts to form and therefore the development of hail.  One of these supercell thunderstorms spawned a tornado in Bienville Parish that uprooted and snapped several trees in an unpopulated area of the parish.

An EF1 tornado uprooted and snapped several hardwood and softwood trees along Mamie Murphy Road, Old Sparta Road and Kepler Road.  The path length was 2.28 miles while the path width was 0.5 miles with maximum winds estimated to be near 100 mph.
A line of thunderstorms ahead of an approaching cold front started developing and intensifying in the mid to late afternoon hours across northern Georgia and Alabama. There were also discrete supercells developing ahead of the main line during peak heating. The line approached the western part of the forecast area around 9 pm as the line was beginning to interact and consolidate with the discrete cells out ahead of it. The line swept across the entire forecast area with numerous reports of wind damage and a smaller collection of large hail. The near storm environment was marked by impressive mid levels with 500-700 mb lapse rates less than -7 C/km and LI's as low as -3 to -4 C. The presence of an elevated mixed layer resulted in DCAPE values in the 800-1000 J/kg range. The upstream convective line was forced by strong ambient shear (on the order of 50-60 kts in the 0-6 km layer) with adequate surface based instability (CAPE in the 500-750 J/kg range). The supercell elements upstream yielded a tornado threat which subsequently diminished into the forecast area with less instability present and a convective mode favoring linear segments.  The Storm Prediction Center hoisted a Severe Thunderstorm Watch around 7:30 pm for all of southeast Georgia and the portion of South Carolina that bordered the Savannah river. The line maintained its strength as it passed over South Carolina and Georgia coastal waters.

A cold front moved slowly southeast into central Iowa.  The airmass became unstable around the front with highs in the mid 80s to around 90 ahead of the front with dewpoint temperatures in the 55 to 60 degree range.  There was 40 to 50 kts of effective shear available, however CAPE was generally only around 500 J/kg in the thunderstorm generation area behind the front.  Downdraft CAPE was in the 600 to 800 J/kg range with available in the -10 to -30 C layer of the atmosphere between 100 and 200 J/kg.  Precipitable water values were around an inch with a 35 kt low level jet feeding moisture into the area.  The freezing level was relatively low, around 11,500 feet.  As a result thunderstorms that formed produced hail easily.  By the late afternoon into the evening hours an area of thunderstorms formed on the cool side of the front.  Several of the storms produced hail up to quarter size.  One storm produced a swath of one inch diameter hail in Adams County from Lake Icaria northeast to the county border.  By the end of the month a Presidential Disaster Declaration was issued due to the winds and flooding for the following counties: Appanoose, Cedar, Clinton, Davis, Decatur, Des Moines, Iowa, Johnson, Keokuk, Lee, Lucas, Marion, Monroe, Muscatine, Ringgold, Van Buren, Wapello, Warren, and Wayne Counties.
