    The SPC has a day-3 Enhanced outlook for Abilene TX to near Lubbock and Midland-Odessa. The NAM and GFS show that dew points will be in the 60-65F range with 500mb winds around 45-50 kt in advance of an upper level trough.

    The 12z NSSL-WRF is quite vigorous in predicting higher updraft helicity tracks into NW Louisiana this evening at 02z to 04z.

    Dodge City radar is down due to maintenance concerns. A severe thunderstorm watch has been issued near Dodge City. Murphy's Law for Weather Radar: If something can go wrong, it will go wrong as severe thunderstorms are about to develop.

    The SPC has a slight risk for the central area of Nebraska down to near Midland/Odessa Texas today. 0-6 km shear should be at least 50 kt, as 500mb winds are at least 50kt. Shear may even up to 65 kt in some instances for storms that develop today. Medium values of LCL and storm-relative helicity may limit tornado potential.

    kind of a messy storm mode- and tornado reported at Hickman KY

    The area near Butterfield MO looks stronger on rotation. Yep, a lot happening in SE Missouri, and Paducah's radar is kind of far away from it to see the rotation.
  7. Chinook
    That area near Purdy MO has had some distinguishable rotation on SRV1, right near that funnel cloud sighting by a spotter. Perhaps this one could develop a tornado.

    The NAM has 65-66 degree dew points into SE Oklahoma Monday. My guess is that the SPC will issue a slight risk on Monday. Until a couple of days ago, the GFS runs had basically no CAPE for Monday. But now I think a localized hail/wind threat is possible.

    SPC has an outlook (15%) for Day-4 Arkansas, Day-5, AL/MS/TN. The GFS has over 1000 J/kg of CAPE at 12z on Wednesday, in Arkansas. Synoptic details will probably change a lot, but that's a lot of CAPE for 12z in the winter.

    I have not heard of any damage report, but here is the warning - THE NATIONAL WEATHER SERVICE IN AUSTIN SAN ANTONIO HAS ISSUED A * TORNADO WARNING FOR... * UNTIL 1115 PM CST * AT 1038 PM CST, A SEVERE THUNDERSTORM CAPABLE OF PRODUCING A TORNADO WAS LOCATED OVER SAN ANTONIO INT AP, MOVING NORTHEAST AT 35 MPH. HAZARD...TORNADO. SOURCE...RADAR INDICATED ROTATION.

    I figured this might be relevant for anybody interested in Houston's heavy rain.

    There is a reference to CASA radar in this tornado warning. This could be a dangerous situation if there is a tornado on the ground near the metro area. (not sure if a tornado is on the ground)

    tornado reported at Laguna Park
  15. Chinook
    The SPC has put out a slight risk for severe weather in mid-Texas tomorrow. Some NAM forecast soundings west of San Saba at 00z Monday (36 hrs) show 1000 J/kg of CAPE, 59 kt effective shear, 410 m2/s2 effective SRH. Convection-allowing models all seem to have a squall line around San Angelo.
  16. Chinook
    It looks like the CAPE will be higher at nighttime than in the daytime. There might be a half-dozen storm reports at 4:00AM. The convection-allowing models show showers and thunderstorms traveling or developing some 300mi+ eastward across Texas in the time frame of 06z to 12z. There could be a number of severe storms. It would be very climatologically unusual for a severe storm at 3:00AM on January 2nd.

    NWS Cleveland created a map and a snowfall summary for the lake effect snow that happened recently http://www.weather.gov/cle/event_20161208-1210_LakeEffectSnow

    flash flood threat in New Mexico. WPC mesoscale precip. discussion: SUMMARY...A FLASH FLOOD THREAT WILL CONTINUE ACROSS ERN AZ INTO WRN NM INTO THE EARLY EVENING HOURS... CONTINUED TRAINING AXES OF HEAVY RAIN ARE EXPECTED ACROSS PORTIONS OF ERN AZ INTO WRN NM THROUGH THE REMAINDER OF THE AFTERNOON WITH POSSIBLE FLASH FLOODING FROM LOCALIZED RAIN RATES OF 1-2 IN/HR.

    Typhoon Haima, now a lot weaker, is approaching Hong Kong, and the large ragged eye is visible on Hong Kong radar. JTWC predicts it will make landfall ENE of Hong Kong.

    Colorado State/CIRA web page for Typhoon Haima. You can click on archive, that is a link underneath each current picture. If you want to look at how this storm developed, pick begin and end frames for different types of satellite loops. note: enhanced IR images should give you lots of frames to loop. You could also view individual pictures since the beginning of the storm. http://rammb.cira.colostate.edu/products/tc_realtime/storm.asp?storm_identifier=WP252016
  21. Chinook
    In my opinion, it looks like it has a 40nm wide eye and -80C temps in the CDO region, all the way around the eye. I think there might have been some -90C temps in the CDO earlier today. this is from the Typhoon Haima JTWC discussion #17.
  22. Chinook
    another beautiful picture (water vapor channel) of these two terrible storms. Typhoon Sarika made landfall today on Luzon Island, Philippines. It may have brought a large amount of flooding, but I did not check news sources about this. Typhoon Haima takes up the center of this image, with cirrus outflow extending from the equator to 20deg north

    Blame it on the TV show

    Severe thunderstorm warning was issued for Norman before the Ohio State- Oklahoma game started, I believe, as people were waiting for the game to begin. (or during the game?)
