3D view of the large overhang of high reflectivity in northern Nebraska, including a rare 75dBz pixel on the base reflectivity (radar estimated 2.7" hail) And oh, by the way, 300mb winds are 100 knots over this storm.
The SPC has put out an enhanced risk of severe weather for the central plains tomorrow, that was the 17z outlook. Tonight's models show a large number of storms developing on the cold front in southern Nebraska. The shear could be 45 kt- 60 kt with CAPE values up to 2000 J/kg. Some supercells will form, with most likely a low storm-relative helicity and lower chance for tornadoes in most areas.
Today may be our first normal-looking summer day with dew points around 50 and scattered thunderstorms. My place has a dew point of 48 and there's already some lightning east of Estes Park.
I was away on a trip. Then I came back to DIA and got my car and all this rain happened. So, not very fun driving. It was 42 degrees. Major shock. It was 90 degrees when I left DIA.
There will be a high significant tornado parameter developing after 22z, toward Duluth. It is likely that several supercells develop in western Minnesota near the low pressure. The storms may develop in a squall line but I expect the shear to he high enough force supercells to occur. The highest dew points and storm relative helicity will in the eastern half of Minnesota.
Colorado Springs to the Palmer Divide probably had a lot of broken tree branches. I really don't know for sure. I think Denver got 1.20" of precipitation.
I think I got less than 1" on the trees and the grass. I think I got over 0.75" on precipitation. According to the NWS, I guess my area still has "Chance Snow Showers then Slight Chance T-storms" tonight.
all right. here we go. High temps on 5/19. not shown on this plot are high temps of about 86-91 in the Denver metro area.
down to 42 degrees. There is a bit of drizzle
multiple areas that could be tornadoes near western Saint Louis
edit: there may be tornado debris at Ladue/ Kirkwood? I have not heard any spotter reports.
