FIRE WEATHER PLANNING FORECAST FOR SOUTHEAST WYOMING/WESTERN NEBRASKA
NATIONAL WEATHER SERVICE CHEYENNE WY
200 AM MDT SAT SEP 12 2026
DISCUSSION
THE REGION SHOULD SEE SOME BRIEF RESPITE FROM
CRITICAL CONDITIONS THIS WEEKEND, THOUGH AN ELEVATED FIRE WEATHER
ENVIRONMENT WILL BE POSSIBLE IN CARBON AND ALBANY COUNTIES TODAY
AS RH VALUES DROP DOWN INTO THE UPPER TEENS TO LOW 20% RANGE.
SURFACE MOISTURE WILL INCREASE ON SUNDAY KEEPING THE ENTIRE REGION
OUT OF CONCERNS, BUT ON MONDAY A CRITICAL ENVIRONMENT WITH
WIDESPREAD 10-20% RH VALUES IS EXPECTED. IT WILL ALSO BE WINDY
ALL WEEKEND FROM STRONG SURFACE PRESSURE GRADIENTS, WITH GUSTS
EACH DAY BETWEEN 25-45 MPH OR HIGHER. WINDS WILL SHIFT QUITE A BIT
THROUGH THE WEEKEND AND INTO NEXT MONDAY DUE TO PASSING FRONTAL
BOUNDARIES, AND WITH THESE STRONG WINDS PLUS THE DRY ENVIRONMENT
ON MONDAY A CRITICAL ENVIRONMENT LOOKS PROBABLE FOR MUCH OF
SOUTHEAST WYOMING. THEN INTO NEXT WEEK, MOST DAYS LOOK TO REMAIN
OUTSIDE OF CRITICAL STATUS.
