. On May 25, 2007, WFSB's studios were flooded by a water main break. The flooding knocked out power and phone service to the building which in turn caused WFSB to go dark. WSHM's master control was also affected and the station went black for about an hour mid-afternoon and intermittently throughout the evening. There were some points during the weekend that its "CBS 3 Springfield" IDs were seen on WFSB while that outlet's IDs were seen on WSHM. On June 27, the master control and internal operations of WSHM and WFSB moved to a newly constructed facility (south of Hartford) in Rocky Hill. Since it is a low-powered station, WSHM was exempt from the FCC-mandated switch to digital-only broadcasting on or before June 12, 2009.

News operation

Initially as a semi-satellite of WFSB, WSHM did not operate a news department of its own nor did it simulcast any local newscasts from its parent. In October 2005, WSHM finally established a news operation and began producing local news from studios in Monarch Place in Downtown Springfield's Metro Center section. It was the first station in the United States to use Grass Valley's "Ignite" control room system. Originally, ''CBS 3 Springfield News'' was only seen Monday through Saturday nights at 6, Sundays at 6:30, and every night at 11. Initially after entering the news race in the Pioneer Valley, it struggled to make a dent in the ratings of longtime market leader

affiliate WWLP and established runner up ABC outlet WGGB. Eventually, this station grew substantially across the board during the May 2009 sweeps period to within decimal points of WGGB in several key demographics. Compared with the area's two other commercial television stations, WSHM tended to have a flashier format in its newscasts featuring more fast-paced coverage. Fending off a challenge by WGGB, WSHM debuted the area's first prime time newscast on August 18, 2008. Known as ''CBS 3 Springfield Non-Stop News at 10'', the twenty-minute program aired in a commercial-free format on its then cable-exclusive local weather channel seven nights a week (the program was also streamed live on its website).

affiliate WGGB-DT2 which started its own nightly prime time show at 10 on September 8. At some point in time for an unknown reason, WSHM's 10 p.m. broadcast was dropped. On August 24, 2009, it began airing a thirty-minute show on weekday afternoons called ''CBS 3 Springfield News First at 4''. It was the first Pioneer Valley station to make such a launch. The program was expanded to sixty minutes on February 4, 2013. In September 2010, WSHM debuted an updated local news format that contained the top stories of the day and a full weather segment shown in the first five minutes of all newscasts before a commercial break. To go along with the change, a new logo was made public and included an updated music package and graphics theme identical to WFSB. In the past during

radar data from several regional sites began to be used interchangeably with WFSB's radar and was branded on WSHM as "Pinpoint Doppler". Following Meredith's purchase of WGGB, the news operations of WGGB and WSHM were merged under the ''Western Mass News'' branding on April 21, 2015. The combined news operation is based out of WGGB's facilities on Liberty Street; this led to the closure of WSHM's Monarch Place studios following the April 20, 2015, newscasts. As a result of the merger, WGGB and WSHM simulcast the weeknight 6 p.m. and nightly 11 p.m. newscasts. WSHM retained its weekday afternoon local news hour from 4 until 5 which is not seen on WGGB. In addition, its partnership with the Springfield ''Republican'' and MassLive was extended to include WGGB. Also, as a result of the change, local news is now carried in high definition, an arrangement not possible when WSHM was at its previous facilities.

Analog-to-digital conversion

An application filed with the FCC calling for WSHM to launch its own low-powered digital station on channel 49 was dismissed in June 2006. Another application to move the existing analog signal to channel 45 was dismissed in 2004 at the station's request. More recently, WSHM had a

to air a low-powered digital signal on UHF channel 21. On November 22, 2010, this became active after WSHM finally gained a "license to cover" allowing it to turn-off its analog signal (on channel 67) and activate its own digital signal for the first time. On January 7, 2011, to reflect the change to digital-exclusive transmission, its calls were officially changed to WSHM-LD. WFSB's digital signal continues to have good reception into southern areas of the Pioneer Valley, thus allowing access to two CBS affiliates. In the fall of 2022, a new transmitter for WSHM was activated atop Mount Tom on the WGGB tower, which now provides a solid signal for the region from north of
