Interestingly, on the evening of October 22 (23/00z), PWAT was the 5th highest ever recorded during the month of October. On Thursday (11/26), the PWAT measured on the evening sounding at Fort Worth was the 3rd highest ever recorded in the month of November. In particular, I have found the 99th percentile to be a critical threshold. I have had excellent success at forecasting heavy rain events by using the PWAT (atmospheric precipitable water content) percentile. Atmospheric Precipitable Water Content (PWAT) Percent increase in each “all-time” record over its predecessor (i.e., ranked annual rainfall from wettest to driest).

The other occasion was October 22-23, 2015 when DFW received 6.13″ in 2 days. This is the second time just since October 1 that this has occurred. This is the single greatest 2-day total ever recorded between September 23 and April 24 (215 days, including Leap Day). The two-day rainfall total for 11/26 and 11/27 was 6.16 inches. The 3.45 inches of rain on 11/27/15 is also the third greatest calendar day amount ever recorded between November 1 and March 10. This not only broke the daily record, but it also broke the record for the greatest amount of rain ever recorded on any calendar day in the month of November (previous record = 3.24″ on ). On Friday November 27, 2015, DFW Airport received 3.45 inches of rain. Details of the broken rainfall records at DFW 2015 has certainly been one for the record books.
