POTENTIAL CONFLICT WITH LTSS BTWN 2 MIL BMB AND AN ACR MLG.

Narrative

WE WERE THE LEAD OF A 2 SHIP FORMATION. THE SECOND ACFT WAS AT FL245 (LEAD WAS AT FL240). AS WE APCHED OUR TURN POINT ON THE N CORNER OF THE UTTR TEST RANGE; WE PASSED THROUGH A CLOUD AND PICKED UP SOME ICING. WE TURNED TO THE NW TO EXIT THE WX SINCE THE ACCUMULATION RATE INCREASED. ONCE WE ENTERED THE CLR OUR RADAR PAINTED MOISTURE TOWARDS THE NE. VISUALLY; WE DETERMINED THIS TO BE MULTIPLE TSTMS. WE ADVISED CLOVER CTL THAT WE WERE DEVIATING FOR TSTMS; AND WOULD START OUR TURN TOWARDS THE S WHEN WE COULD. SOON AFTER; WE STARTED OUR TURN AND ADVISED HIM. CLOVER ADVISED US WE WERE N OF THE AREA AND WE TOLD HIM WE WERE CORRECTING BACK; WHILE AVOIDING WX. NO MENTION OF ANY TFC WAS MADE TO US. A MIN LATER; OUR SECOND ACFT WAS ADVISED OF TFC AND TOLD TO DSND TO FL240. BECAUSE HE WAS IN AND OUT OF THE WX; HE TOLD CLOVER 'UNABLE;' AND SHORTLY AFTERWARDS DECLARED AN EMER. AFTER ROLLOUT; EACH ACFT WAS GIVEN SEPARATE CLRNCS OUT OF THE AREA. THE TSTMS PREVENTED US FROM TURNING AS PLANNED. WHILE CLOVER SEPARATES MIL ACFT; HE IS NOT AN FAA CTLR. LIKEWISE; HE DIDN'T ADVISE SALT LAKE CTR OF OUR WX PROBLEMS. WE SHOULD HAVE DECLARED AN EMER BEFORE WE EXITED THE AREA (WE THOUGHT CLOVER WAS A CTLING AGENCY). ONE OTHER OPTION WOULD HAVE BEEN TO REQUEST FL230 VERSUS FL240 AND DSND 1000 FT. THIS WOULD HAVE GIVEN OUR SECOND ACFT THE PROPER SPACING. SALT LAKE CTR HAD AN ACFT 2 MI AWAY AT FL250 WHICH OUR SECOND ACFT WAS IN CONFLICT WITH.
