    Denver: chance of rain, all days

    A long time ago, I remember a "weather weenie" run of the ECMWF that said that Hurricane Sandy would come into the coast. Then, a week later, it was a $70 billion disaster. And the WPC invented the term "Frankenstorm" but then regretted it! Note: Hurricane Lee recent recon says 962mb and maybe 80 kt at the surface, so the NHC value of 95 kt is generous.

    Here's a great full-disk satellite view of major hurricanes Lee and Jova (1500z on September 7th)

    There's not a whole lot of storms that ever reach 140 knots. I guess we will see if it can truly recover to the 120kt as forecast by the NHC at this time. I would say that the current ongoing recon pass has about 95-97kt of flight level winds, and 960 mb. It honestly it may be about 87 knots for the surface winds, and the 960 is impressive, but obviously not the 930mb and such. So yeah, a long way downward form Thursday night.

    Some of our days this week will be the first below-normal five-day period for Oklahoma and Arkansas for a long time. Dallas hasn't had a week below normal since June 18th, considering all running 7-day periods

    There were 426 storm reports from the slight risk! Did all of you guys in the Mid Atlantic Discussion thread do a spotter report or something? Because I know several of you live in Maryland. And it would appear there will be more severe reports in the Northeast corridor today.

    wow, 70 kt at 5:00AM 90 kt at 11:00AM and 140 kt at 11:00PM. So, yeah, I think your comment is about accurate. that's a +70 kt in 18 hr. I can't think of anything like that. I think Hurricane Andrew did something crazy like this in 1992 but it may very well have been many more hours. (Edit: just read the post about Hurricane Wilma.)

    record-tying heat wave for Minneapolis

    wow, I didn't even think of it, but you can barely make out a supercell shape, even though the yellow/orange/red kind of dominates the image

    confirmed tornado near Wilmington NC

    This isn't very circular very more. Rectangular hurricane. Honestly I said that because the gap in the observations is a long rectangle. Well anyway, 988mb is still pretty low but believable as it has gone up about 48mb as a result of landfall and convergence.

    957.6mb measured, as the conversion of 28.28" on the altimeter

    The hurricane must have gone very close to this buoy, but maybe not right on. Quick calculation says that this measured 972.5 mb.

    I wanted to post these before I fall asleep. The recon got over 101 kt at flight level, for three passes as shown on the time series. The last two passes show some asymmetry. One buoy north of the storm says (39 kt) 45mph gusting to (56 kt) 65mph (that's buoy 42036). So you might check this in about 1-2 hours to see if the buoy picks out the highest wind speeds or lowest pressures.

    tropical tidbits says the recon is still in progress. It seems like it has been going on since 8PM or something

    recon says 957.6mb on the minute-by-minute plot
  19. Chinook
    it says 960.6 on the minute-by-minute recon obs zoom-in as shown on Tropical Tidbits
  20. Chinook
    Here is the radar image, showing wind gusts measured up to 49mph in the last hour. Maximum radar base velocity of 87kt toward the radar and 69kt away from KTBW.

    GFS 250mb winds (barbs) 250mb height (just the colors, that's pretty much all red) and MSLP (black contours)
  22. Chinook
    Wow! It's 927mb as shown with the tropical tidbits graphic w/satellite. That is a low pressure. The tail end of the recon pass says 130kt approximately at flight level (Previously posted by Windspeed: early part of the recon pass) and maybe 113kt at surface. At some points in history, we have seen storms with category-5 status with pressure close to 920mb and below. Thanks BostonBulldog for posting incredible graphic that says 140kt briefly.

    Here is an animation of the contoured of the heat index at 21z for the entire Midwest heat wave.

    Today was, thankfully, a very normal day with partial clouds. It topped off at 82 with a dew point of 64. Yesterday was almost entirely cloudy and in the upper 70's for the high. The sunset tonight has some pink cirrus clouds and some gray cumulus clouds that are kind of blocking me from seeing the sunset. Also note: Toledo CoCoRAHS reports got 3.09" to 3.85" over 48 hours this week. I was able to stay up to watch a lot of lightning on the second one.
