Fire Weather Planning Forecast for Southeast Wyoming/Western Nebraska
National Weather Service Cheyenne WY
1027 AM MDT Thu Jun 17 2021
RED FLAG WARNING IN EFFECT UNTIL 7 PM MDT THIS EVENING
.DISCUSSION...
Hot, breezy and mostly dry conditions will persist Thursday.
Critically low humidities, winds and high Haines indices will maintain
high fire danger along and west of the Laramie Range. Fuels are conducive
to rapid fire growth in the Sierra Madre, Snowy Range, North Laramie Range and
South Laramie Ranges to warrant Red Flag Warnings in effect from 11 AM
to 7 PM MDT. A weak front will bring cooler temperatures and lighter
winds Friday, followed by warmer temperatures and gusty winds
Saturday. A stronger front will usher in much cooler temperatures
Sunday and Monday, along with scattered showers and thunderstorms.
