Severe storms possible Sunday through Tuesday
Sun, 19 May 2013 01:20:51 GMT —
UPDATE Sunday 5/19 9:00 p.m.
A Tornado Watch continues until 1:00 a.m for the entire viewing area except for Phelps County. One line of severe storms has crossed into western mid-Missouri, bringing winds between 50-60 miles per hour and hail less than an inch in diameter. A secondary line has crossed through the Kansas City metro, bringing minor wind damage in the form of broken tree limbs and downed powerlines.
This line has broken up and the stronger section is beginning to move northeast.
We will continue to monitor further development in eastern Kansas as the night progresses.
UPDATE: Sunday 5/19 6:00 p.m.
A line of severe thunderstorms is racing across eastern Kansas at this hour. This line is moving very quickly to the east, and should reach the Kansas City metro area between 7:00 and 8:00 p.m. This means the threat for mid-MO should increase by 9 or 10 p.m.
These storms are capable of producing widespread wind damage and have a history of producing tornadoes that caused damage in the Wichita area prior to forming a line.
The primary threats will be damaging winds and hail greater than an inch, but embedded tornadoes along the line are still possible.
UPDATE: Sunday 5/19 3:00 p.m.
Mid-Missouri is still under a slight risk for severe weather Sunday night into Monday.
The atmosphere is destabilizing with the help of plenty of sunshine, moisture, and gusty, warm south winds.
Tornado watches are in effect to the west of the viewing area, including northwest Missouri and the Kansas City metro area. Thunderstorms are starting to erupt along a frontal boundary. I think the primary tornadic threat will be over Kansas and the Missouri-Kansas border this afternoon and evening, but a few isolated tornadoes will still be possible in mid-Missouri tonight.
A strong squall line will form as these storms converge tonight, pushing through the area between 9 p.m. and 2 a.m. The severe threat will wane over the morning hours tomorrow then ramp back up in the late aftenoon as a secondary upper level wave pushes through the Plains.
The SPC has also placed the entire viewing area under a slight risk for severe weather on Tuesday.
PREVIOUS UPDATE (5/18):
The Storm Prediction Center in Norman, Oklahoma has placed the entire KRCG 13 viewing area under a slight risk for severe weather Sunday and Monday.
A strong upper-level trough is digging across the Plains Saturday night and with it bringing ample moist, unstable warm air to fuel strong to even severe thunderstorms.
Some storms have had a history of producing tornadoes in Kansas, as well has large hail and damaging winds.
This system will begin to impact mid-Missouri late Sunday afternoon into the evening hours. Another system will come through Monday, bringing another chance for severe weather.
High temperatures tomorrow will be in the upper 80s, with dew points in the middle to upper 60s, providing a fueled atmosphere for storms to grow quickly.
These storms will be capable of damaging winds, hail up to or greater than 1", and isolated tornadoes.
