    Dew points of 60-70 will exist southeast of the cold front on Sunday, with a low pressure in Iowa/Missouri. In general, the models have strong winds at 850mb-500mb, leading to some areas of 0-3km storm-relative helicity of 250m2/s2 or better. Models have 40-60 kt of wind at 500mb over Arkansas/ Missouri, leading to 0-6km shear in that range of values.

    It's now 10/17. And Raindance was... right. A compact 500mb low is cutting off right now near the Sierra Nevada, and will track through Wyoming, bringing snow to some areas of the Sierra Nevada to Wyoming. Winter storm watch for some areas of Wyoming

    Here are some more maple leafs. Well, not Toronto Maple Leafs. 2nd picture: ash. 3rd picture: some type of bush where the leaves resemble maple leaves.

    mountains partially clouded (Wednesday)

    My area had a few minutes of rain, graupel, and lightning, and even thunder somewhat close by. Then, today turned out to be pretty nice, not too windy like Cheyenne.

    TDS about 7 mi from Dodge City

    confirmed tornado near Copeland KS

    Interesting weather note this evening. The upper level low over the Southwest is bringing in so much wind, the flags are flying at Dodger Stadium, the likes of which I've almost never seen for a southern California baseball game.

    location of two confirmed tornado warnings several minutes ago (3:53pm Central), also, prelim. tornado report near Jacksonville IL

    This is a 12z HRRR run for tomorrow night. The afternoon-evening SBCAPE should be a narrow area of possibly 500 J/kg to 1500 J/kg in western Kansas and down into the Texas Panhandle. Models show convective development. I wonder if the deep layer shear could be too powerful for supercells, given the limited CAPE. As in, the shear could be so great it disrupts updrafts.

    might as well post this. NWS point forecasts for RMNP have 4"-8" at high elevations

    confirmed tornado at Johnson, OK (0157z radar showed a TDS)

    new confirmed tornado warning east of OKC

    new tornado warning extends about 35 miles east to west

    tornado that was reported at Cooperton

    1st supercell of the day in the process of developing now in SW Oklahoma.

    The 15z HRRR has some big updraft helicity tracks right through Norman and other areas!

    Believe it or not, this is an oak tree. Many of the cottonwoods haven't changed to bright yellow yet.

    NAM-3km cross section through the cold front and directly through the severe thunderstorms. Huge differences in upward motion mess with the isentropic surfaces. You can see a slight reduction of the 0C isotherm going towards the left side of the plot.

    one confirmed tornado on a squall line in eastern South Dakota.

    NWS-WPC 168-hr precip map expecting up to 1" to 1.5" of QPF for western Colorado, and also including upper Larimer County, and 1.0"-2.0" for Wyoming, so possibly high-impact snowfall for areas up near Casper, WY. And, of course, the first snow storm for Colorado for the season, certainly above 6000-7000 ft for the west and central.

    hey, King Euro had some fantasy snow for me, for one run.
  24. Chinook
    This seems intriguing. Perhaps 10/9 might be an interesting day to see what the ensemble averages have for 10/19
