If you blinked, you missed summer's last hurrah — and nearly missed a serious fire scare while you were at it. Helena swung from near-record 80-degree heat early in the week to a full Red Flag Warning by Thursday, before temperatures crashed and snow threatened the weekend. The National Weather Service office in Great Falls issued a Fire Weather Watch that escalated to a Red Flag Warning covering the Central and Eastern Lewis and Clark National Forest, a rapid upgrade that underscored just how quickly conditions can turn dangerous in October. The Helena-Lewis and Clark National Forest had prescribed burns active near the Continental Divide and in the Lincoln Ranger District at the same time, adding smoke to an already unsettled picture. What this means for residents: fall in Helena isn't fire season's end — it's fire season's last, unpredictable gasp. The whiplash from heat to snow compressed that window dramatically this week, and officials want you paying attention right up until the first hard freeze sticks. The National Weather Service Great Falls office appeared repeatedly in coverage this week, issuing multiple alerts that shaped how residents planned their outdoor time.
