Fire Weather Planning Forecast for Southeast Wyoming/Western Nebraska
National Weather Service Cheyenne WY
346 AM MDT Fri Jul 21 2017

.DISCUSSION...

Scattered thunderstorms are expected today over the mountains, and
areas along/south of I-80 from Laramie to Sidney. The main hazards
will be lightning and gusty/erratic surface winds. RH will fall to
near 15 percent over east central WY and the northern NE Panhandle
this afternoon as dry air works in behind a cold front. Otherwise,
expect RH values between 20 and 30 percent. Light winds are likely
to keep fire weather concerns very low through the weekend.
