Advisories on Tropical Storm Bill<\/strong><\/a> were initiated when the system organized and intensified off the coast of Texas at 03 UTC on 16 June 2015<\/strong><\/a> (GOES-13 IR image animation<\/strong><\/a>). Bill moved inland during the afternoon hours on 16 June, as can be seen in a comparison of Suomi NPP VIIRS 0.64 \u00b5m visible channel and 11.45 \u00b5m IR channel images at 1916 UTC (above)<\/strong><\/em>.<\/p>\n

Late in the day on 17 June, the general appearance of downgraded Tropical Depression Bill on GOES-13 6.5 \u00b5m water vapor channel imagery (below)<\/strong><\/em> began to suggest that the system might be undergoing an extratropical transition (intrusion of dry air in the southern quadrant, along with a blosominig comma head signature on the northern quadrant) — but Bill maintained sufficient tropical characteristics to continue being named a tropical depression.<\/p>\n

The circulation of TD Bill maintained its identity on satellite imagery as the storm remained over land for the next 3+ days, curving northeastward and moving across the Ohio River Valley region. Slow-moving TD Bill dropped over 12 inches of rain at some locations in Texas and Oklahoma, with amounts exceeding 8 inches in Missouri and 6 inches in Indiana (WPC storm total rainfall totals<\/strong><\/a>), before being designated a post-tropical feature at 21 UTC on 20 June<\/strong><\/a> (WPC advisories<\/strong><\/a>).<\/p>\n

The history of Bill can be followed in a multi-day animation of GOES-13 10.7 \u00b5m IR channel imagery (above);<\/strong><\/em> in addition, the lower-tropospheric circulation of Bill can be followed using the CIMSS 850 hPa relative vorticity product<\/strong><\/a> (below)<\/strong><\/em>.<\/p>\n

As the post-tropical remnants of Bill emerged over the Atlantic Ocean early in the day on 21 June<\/strong><\/a>, it still appeared to be associated with an arc of deep convection as seen on a comparison of Suomi NPP VIIRS 0.64 \u00b5m visible channel and 11.45 \u00b5m IR channel images at 1742 UTC (below)<\/strong><\/em>.
