FIRE WEATHER PLANNING FORECAST FOR SOUTHEAST WYOMING/WESTERN NEBRASKA
NATIONAL WEATHER SERVICE CHEYENNE WY
118 AM MDT TUE MAY 19 2026
DISCUSSION
NO FIRE WEATHER CONCERNS OVER THE NEXT WEEK DUE
TO RECENT WIDESPREAD PRECIPITATION, MUCH HIGHER HUMIDITIES, AND RECORD
COLD TEMPERATURES. A SLOW WARMING TREND IS EXPECTED AFTER TUESDAY,
BUT TEMPERATURES WILL BE SLOW TO RETURN TO NEAR AVERAGE FOR THIS
TIME OF THE YEAR. IN ADDITION TO DAILY CHANCES FOR ADDITIONAL
SHOWERS AND THUNDERSTORMS, A CLIPPER SYSTEM IS FORECAST TO DIG SOUTH
INTO WYOMING AND STALL, RESULTING IN ANOTHER CHANCE FOR NUMEROUS
SHOWERS AND ISOLATED THUNDERSTORMS THURSDAY AND FRIDAY.
