The temporary relief brought by a late February blizzard continued to diminish due to limited precipitation during the month of April. Exceptional (D4) drought affects all of Cimarron and Texas County, and Beaver County remains in extreme (D3) drought. While precipitation was  limited during the month of April, Guymon recorded 0.49 inches of precipitation (1.02 inches below normal).
Limited dormant fuels remain in prime condition for the spread of fires across the Panhandle. The Keetch-Byram Drought Index remained steady state for the month of April with Texas County in the 600 to 800 range, while the remainder of the Oklahoma Panhandle remains in the 400 to 600 range.
The sparse precipitation for the month and several freezes severely impacted the winter wheat crops. The Palmer Drought Severity Index for the month of April showed a degradation of conditions across the Panhandle with the entire Panhandle now rated as Moderate Drought. Water watches remain in effect for several public water systems through April with voluntary to mandatory water restrictions enacted.
Economic losses due to the drought for April were estimated near $15 million (D3)/$25 million (D4) a county, and were predominately the result for poor growth of winter wheat, heavy supplemental watering, and supplemental feed for cattle in pastures and rangeland.

During the early morning hours of the 2nd, patchy drizzle developed across the Oklahoma Panhandle. Given at or slightly below freezing surface temperatures the drizzle froze on elevated surfaces such as bridges and overpasses. Less than a tenth of an inch of ice accumulations were reported in Cimarron and Texas Counties. However, the slick conditions resulted in a few vehicle accidents. Icy road conditions were reported near Boise City (Cimarron County), and icy bridges resulted in a one vehicle accident in Guymon (Texas County). No injuries were reported with this accident.
During the afternoon hours of the 2nd, a cold front moved southward across the Oklahoma Panhandle. Temperatures behind the front quickly dropped 10 to 15 degrees and continued to drop throughout the evening hours. At the same time a closed low moved to the southeast from the Four Corners Region. This low provided the lift needed for warm moist air to ride overtop the intruding cold surface airmass and produce light drizzle. As the overnight hours progressed, surface temperatures dropped below freezing causing the drizzle to freeze upon contact with elevated surfaces such as bridges and overpasses. The freezing drizzle continued through the overnight hours and into the early morning hours of the 3rd. By 6 AM CST, the closed low had progressed far enough southeastward to cause the freezing drizzle to intensify into a band of light freezing rain that moved from west to east across the Panhandle. By noon of the 3rd, the upper low had progressed southeastward enough to send the band of light freezing rain into western Oklahoma. The frozen precipitation caused numerous vehicle related accidents across the Panhandle.  However, no injuries were reported in association to these accidents.

A very warm and humid air mass was in place across southern Vermont on Tuesday, May 21st. A slow moving frontal boundary was situated just north of the area across the Saint Lawrence River Valley along the United States-Canadian border. During the day, a wave of low pressure moved along this boundary, allowing the boundary to slowly push southward towards the area. With strong wind shear aloft and plenty of low level moisture in place, thunderstorms developed during the afternoon hours across eastern New York and some of these moved into southern Vermont by evening.
Thunderstorms initially formed as single cells and supercells, but eventually organized into several broken lines, which moved from west to east across the area. One of broken lines of thunderstorms that moved across southern Vermont produced gusty winds, which caused damage to trees and power lines in Dorset.
As the surface wave of low pressure moved away and with the loss of daytime heating, thunderstorms eventually ended during the late evening hours.
