FIRE WEATHER PLANNING FORECAST FOR WRN COLORADO AND ERN UTAH
NATIONAL WEATHER SERVICE GRAND JUNCTION CO
1243 PM MDT TUE JUL 21 2026
DISCUSSION
ANOMALOUS MOISTURE WILL CONTINUE TO FEED
THUNDERSTORM DEVELOPMENT ACROSS EASTERN UTAH AND WESTERN COLORADO
THE NEXT SEVERAL DAYS. STORMS WILL BE CAPABLE OF PRODUCING HEAVY
RAINFALL RATES OF 2 TO 3 INCHES PER HOUR WHICH WILL INCREASE THE
FLASH FLOOD THREAT...ESPECIALLY OVER RECENT BURN SCARS. STRONG
OUTFLOW WINDS REMAIN POSSIBLE GUST OVER 40 MPH AT TIMES. THE PEAK
OF THIS MONSOON PUSH LOOKS TO ARRIVE EARLY WEDNESDAY AND LEAD TO
WIDESPREAD PRECIPITATION CHANCES. A SLIGHTLY DRIER TREND ARRIVES
LATE WEEK INTO THE WEEKEND, ALTHOUGH AFTERNOON STORMS WILL
CONTINUE TO FAVOR THE HIGHER TERRAIN.
...GUSTY ERRATIC WINDS CAN BE EXPECTED NEAR ANY SHOWERS
OR THUNDERSTORMS...
..THE SMOKE DATA IS CALCULATED FROM AN AVERAGE AT 6000 FEET MSL
