NATIONAL WEATHER SUMMARY:
In the East, scattered thunderstorms became numerous again across the Southeast during the midday hours. Heaviest rain fell
across the central Gulf Coast states as well as into southern South
Carolina with over 2 inches in areas. A few severe storms were
noted across the northern Florida peninsula with several power
polls reported down near Lutz. A slow moving boundary also brought
severe weather to portions of New England, southeast New York and
areas of Pennsylvania during the day.
Storms in far northern Maine produced 60 mile wind gusts and hail which covered the ground in areas. Several clusters of storms
became severe during the afternoon across southern New England with numerous reports of hail and felled trees.
Over the Central US, a slow moving low pressure system moved west into central Arkansas bringing heavy rain and thunderstorms to much of the lower Mississippi Valley. A tornado was reported over extreme southeast Missouri and adjacent areas of western Tennessee but was seen moving across farm land with no reports of damage. Another minor tornado along with some gusty winds and hail was noted over southeast Texas but otherwise severe weather was rather minimal across the central states. Scattered thunderstorms were common once again across most of Texas but these mostly dissipated after dark. Other thunderstorms occurred through portions of Nebraska with storms also increasing into the western Dakotas by the evening hours. High pressure brought mostly sunny skies and pleasant weather across the Upper Midwest and western Great Lakes.
Across the West, showers and thunderstorms were again common through the Four Corners region and into the northern Rockies during the day. One storm produced a tornado near Commerce City, Colorado with damage to a trailer and power lines. The west coast
states were mainly dry but rather cool near the coast. Seattle,
Washington set a new record low for the day at 44. A pesky marine
layer brought cool weather to coastal California with highs only in
50s over the northern two thirds of the area. Several locations
near and along the coast broke records for the coldest high
temperature for the date including: Monterey (53); San Francisco
(54); and Oakland (56).

ON THIS DATE IN HISTORY:
In 1955, two tornadoes tore through Blackwell, OK within a few minutes of each other killing 19 people and injuring more than 500.
The same storm later produced a tornado that killed 80 people in
Udall, KS, more than half the towns population.
In 1940, a noreaster brought high winds of 70-90 mph along the coast in addition to heavy rain and record late season snow to portions of New England. The 25 inches of snow that fell at Mt.
Washington, NH set a new May snowfall record.
In 1990, Thunderstorms produced torrential rains and flash
flooding over portions of central MO. 100 people had to be rescued
from Washington State Park near St. Louis as water as deep as 20
feet moved in and swept away a number of vehicles.
