With the iembots alive again and still working (knock on wood), it is a good time to update the follower counts. @iembot_phi has the WFO lead and @iembot_spc is tops overall.

While a lot of focus is on the Texas severe threat today (rightfully so), should not ignore the SUPER RARE significant hail threat for Florida today. Today's hail risk vs. hail climatology. This could be a major story later. #FLwx

Sadly, many of my iembot twitter accounts were suspended again on Monday by @TwitterSupport even though they were on an internal list to avoid such suspensions. Thankfully, I have an advocate at Twitter who is kindly helping to get them back online, just am unsure of timeline :(

Simultaneous tornado and flash flood (emergency) - known as a TORFF - unfolding in the Fort Lauderdale area Warning protocols/communication can be very difficult in these circumstances because the recommended protective actions can be contradictory

No idea how folks can think a 90°F dew point in Iowa is possible... Afix meteorology thinking hat and try to figure out how moisture can be conserved and where said moisture would even go after peak heating. Is the field flooding with condensed water from dew? Good grief.

I've updated the SPC outlook calendar autoplot to allow plotting the hail, tornado, or wind probabilities. Days with significant/hatched risk are flagged with a "H". please let me know of any bugs you see.

Plots showing the yearly average number of minutes that a given county was under a tornado warning. Concurrent polygon warnings for the same county *do not* double count for this analysis. One plot has funky units as being normalized by county size.

With Florida having a Tornado Watch into the early morning hours, I was curious about the percentage of tornado watches for each county that were active/valid at 3 AM CDT (8 UTC). Some local blips are due to small sample sizes, but there's interesting patterns to be seen.

Incredibly bad timing for an outage as folks visit and find no updated information since 4 PM. 6.5 hours into the outage and I have yet to see any status message as to what is going on, outside of something bad happened at College Park data center.
