That shouldn't be a problem for you. I lived in Severance, CO. and monitored the Wyolink from there and anywhere mobile in Northern Colorado. Remember that Larimer and Weld are on 2 different system. Larimer on the Colorado DTRS and Weld on the Front Range (FRCC) system. Your best bet for Larimer county is the Buckhorn or Bald Mtn sites. Weld you will have to experiment with. Checkout the database for both systems, your 996T should do a great job for your with a good antenna.
Any Phase I capable scanner will hear all three systems. The FRCC system is best RX's from the SE part of the county where its used - but can be heard anywhere along the I80 corridor from Cheyenne east.
