A cold front passed through the region on the evening of the 21st. High pressure to the north allowed for plenty of cold air to move into the region during the nighttime hours of the 21st. A wave of low pressure was moving along the front during this time causing precipitation over the area. Precipitation initially started out as rain before changing over to ice and snow as colder air worked its way in.

An unseasonably warm and wet period resulted in minor flooding along the Palouse River in Whitman County. The Inland Northwest remained in the warm sector of a flat ridge with warm air advection into the region. The warm air scoured out the cold air in place, resulting in sharp rises to snow levels across extreme eastern Washington. Record November snowfall, followed by above average December snowfall, set the stage for a healthy low to mid elevation snow pack for many areas across extreme eastern Washington. In these areas, snow levels rose sharply during this period as a series of warm and wet weather systems produced heavy rainfall at times at mid and low elevations. Heavy rain, combined with the melting snow pack, resulted in small streams, as well as, main stem rivers running above flood stage in portions of extreme eastern Washington.

The Palouse River at Palouse overflowed its banks inundating portions of downtown.  The hardest hit were low lying areas, where water surrounded homes and covered nearly all of Hayton Green Park on the west end of town.  A basement of a local resident and a former school gymnasium were flooded on Main Street.  Additional flooding was reported along the Palouse River upstream in Latah County.  The Palouse River at Potlach went above its flood stage of 15 feet at 1630PST on the 16th; crested at 16.5 feet at 530PST on the 17th; and then went back below flood stage at 615PST on the 18th.  No damage was reported.
Temperatures at around 1500 feet above ground level rose above freezing as a warm front began to move across the region.  Surface temperatures remained below zero through much of the morning as the warm air advection accompanying the front took some time to scour out the colder air already in place.  Light precipitation began to fall due to weak isentropic accent.  The pocket of warm air above the surface was enough for much of the Upper Columbia Basin and the Spokane Area to receive freezing rain.  Precipitation amounts were relatively light for the morning hours in the range of 0.01 to 0.05 inches for these areas.

Nearly 150 traffic accidents were attributed to light ice accumulation on area roadways due to freezing rain.  Numerous damaged or disabled vehicles were reported on I-90 through Spokane and Spokane Valley with traffic brought to a standstill in spots along the freeway.  At least six accidents were reported in Lincoln County.  One collision at the intersection of State Route 2 near Oehlwein Road east of Davenport resulted in 3 injuries of two teenage girls and one adult male.
A wintry mix of precipitation occurred across Kent and New Castle Counties on the evening and overnight on the 17th. Snow and sleet accumulations were around an inch or less and ice accretions averaged one to two tenths of an inch. The highest of both occurred in New Castle County. Untreated roadways were hazardous and the wintry mix slowed the morning commute on the 18th. Untreated secondary roadways and some bridges and overpasses remained icy for a few hours after the precipitation changed to plain rain in both Kent and New Castle Counties. Delaware State Police reported about two dozen accidents and four with injuries, most in New Castle County.
Precipitation started as snow in New Castle County, sleet in Kent County and mainly rain in Sussex County during  the early evening of the 17th. As warmer air moved in at the surface and aloft, precipitation changed to freezing rain in Kent County during the middle of the evening on the 17th and started to transition to sleet and freezing rain in New Castle County. The freezing rain changed to plain rain in Kent County shortly after Midnight EST on the 18th, but took until nearly 8 a.m. EST for it to occur completely in New Castle County.
The wintry mix of precipitation was caused by the combination of a low pressure system that emerged from the Gulf of Mexico and an arctic high pressure system that left cold air in place, especially near the surface. The low pressure system moved from the eastern Gulf of Mexico on the 17th northeast to near Cape Hatteras, North Carolina at 7 a.m. EST on the 18th. It moved northnortheast and was just east of Atlantic City, New Jersey at 1 p.m. EST on the 18th. From there it turned more to the northeast and passed south of Montauk Point, New York by 7 p.m. EST that evening. The surface high pressure system was over New England on the evening of the 17th and at 7 a.m. EST on the 18th was centered over Nova Scotia. As it moved farther to the east, the combination of that motion and the low pressure system moving up the east coast cut off the supply of sub freezing temperatures near the coast.

The snow was caused by a cold front that moved through Delaware during the morning of the 7th. The snow was also assisted by a vigorous upper air disturbance.

Deep low pressure of 993 mb crossed Lake Superior into southeast Ontario, taking a cold front across southern Wisconsin. A combination of a tight pressure gradient around the low, with 3-hourly pressure rises of 2 to 3 mb, and clearing skies behind the front during the day, allowed for deep boundary layer mixing. This mixing tapped 30-40 knot (35 to 46 mph) winds just off the surface, which produced strong and gusty southwest winds. Sustained wind speeds reached 30 to 35 mph, with gusts between 35 and 45 mph during the morning and into the early afternoon hours.  Scattered power outages were noted in newspapers due to wind-broken tree branches impacting power lines.

Temperatures in the 80s and dew point temperatures in the mid/upper 60s from southeast Nebraska and southwest Iowa into eastern Kansas created moderately unstable conditions over the area as a large upper level low pressure system organized over Colorado. Due to the circulation of the upper system, the storms lifted north across eastern Nebraska and southwest Iowa. With a boundary bisecting east central Nebraska and western Iowa a few tornadoes spun-up just west and east of the region.  However, in far southwest Iowa the thunderstorms produced mainly just heavy rain as they repeatedly developed and tracked across the same area.

The cooperative observer in Stanton reported that 3.20 inches of rain fell in a 4 hour period.  The heavy rain produced flash flooding along the Tarkio River near town and also produced flooding along the Nodaway River near there as well a little later.
A very volatile atmosphere developed during the late afternoon...evening and overnight hours of April 26th across the Four State Region. An area of low pressure moved from the Texas Hill Country into Northeast Texas during the afternoon. Meanwhile, a warm front had moved northward from central Louisiana and was oriented west to east near the Arkansas/Louisiana state line. A dry line had moved just east of the I-35 corridor of North Central Texas and a strong cold front trailed the dry line. Very strong speed and directional shear was noted in the low and mid levels of the atmosphere such that supercells developed. Many of these produced tornadoes across the region. Other storms produced strong straight line wind gusts with bowing segments and large hail.
