The ILS 11 approach into Missoula, MT (MSO) is a little different in that it requires you to fly the glideslope down to 1350 AGL and then fly 4.1 miles to the runway. This results in a fairly high ceiling minumum for an ILS and quite often, a no-go. Yesterday, while inbound the latest ATIS (50 minutes old) reported overcast 400 ft and 6 miles, not looking good for an approach and I hoped that the update would show the forecasted improvement to allow me to get in. The updated ATIS reported broken 600 ft, overcast 8000 and 6 miles...not looking good. I was below the higher overcast and when I got a look at the broken layer, I requested and was granted a SVFR clearance which worked out OK to get in. Maybe that's typical elsewhere but it struck me as odd that I could get in SVFR but not IFR on an ILS approach.
