Fire danger continues here in late October as months of drought, low humidity, and gusty winds complicate the weather.  A FIRE WEATHER WATCH has been issued for most of central and eastern Montana for Wednesday.  That’s the next significant weather day.  Until then, Tuesday will be a warm and breezy day for most of the state.  High pressure will sprawl across the West spreading sunshine and above average temperatures.  Big Sky Country will be bright and blue Tuesday, with highs in the 60s to near 70.  Southwest winds will gust up to 40mph across the Montana prairies, but little to no wind should blow in the valley locations.  Wednesday will start off sunny and warm, with highs again climbing through the 60s to around 70.  West winds will pick up across the state ahead of an approaching cold front.  Clouds will increase through the afternoon as the front approaches.  Dangerous fire weather conditions are likely through Wednesday evening as the front moves through.  Strong wind, low humidity, and a wind shift will compound the fire danger.  However, rain showers will switch to snow overnight Wednesday into Thursday.  Temperatures will nose-dive from 60s and 70s for highs, down into the 20s and 30s by Thursday morning.  While it does not look like a lot of snow will fall, the temperature drop could create some icy spots.  Thursday will be a much cooler day with highs in the 30s and 40s.  After some morning clouds and snow showers, skies will clear by late morning.  Another warmup is on the way for the final weekend of October, with temperatures rising into the 60s and 70s.  Another cold front will bring temperatures back down Sunday night with a chance of snow later Monday.  Right now, Halloween on Tuesday looks chilly but should be dry.

Have a great day!
