An increase in mid level moisture this afternoon will lead to an increase in shower and thunderstorm activity. Only some of the storms will produce wetting rains of one tenth to one quarter inch. Most areas will only see light if any rainfall. Given how dry the fuels are and receptive to burning, lightning may easily start new fires. There will also be gusty outflow winds in and near the showers and thunderstorms. Most of these will be moving in from the west and northwest, so weather spotters will be essential today in giving a heads up to field crews. Wind gusts up to 45 mph can be expected in association with the showers and thunderstorms. …RED FLAG WARNING REMAINS IN EFFECT UNTIL 9 PM MDT THIS EVENING FOR THUNDERSTORMS FOR FOR THE NORTHERN MOUNTAINS…FOOTHILLS… AND HIGH MOUNTAIN VALLEYS… * Affected Area…Fire Weather Zones 211…212…213…214… 215…216…217 and 218. * Winds…Northwest 5 to 10 mph with gusts up to 25 mph. * Timing…Noon until 9 pm today. * Impacts…Lightning and localized gusty winds from thunderstorms may cause new fire starts and rapid spread of fires. * Thunderstorms…Scattered thunderstorms are expected to move over the mountains, high parks and foothills this afternoon and evening.
