Day 1 Fire Weather Outlook

1128 AM CDT Tue Sep 17 2024

Valid 171700Z - 181200Z

...17z Update...
No changes. Spotty elevated conditions are possible owing to strong
southerly winds ahead of a cold front. Strong gusts may linger after
the frontal passage and with shower/thunderstorms expected later
today. Fire concerns will remain highest within patchy dry fuels
across the southern most portions of the NE panhandle where less
rainfall and lower humidity recoveries have occurred. See the prior
discussion.

.PREV DISCUSSION... /ISSUED 0156 AM CDT Tue Sep 17 2024/

...Synopsis...
A large-scale trough, accompanied by strong deep-layer
south-southwesterly flow, will overspread the northern/central
Rockies and adjacent High Plains. A related lee cyclone will deepen
near western SD, promoting a tight pressure gradient and 20-25 mph
sustained southerly surface winds (with higher gusts) over portions
of western NE during the afternoon. Here, diurnal heating along the
western edge of the richer boundary-layer moisture plume should
yield 20-30 percent RH. Despite these marginal RH reductions, the
strong/gusty winds will still favor a few hours of elevated
fire-weather conditions, before a cold front and related
precipitation overspread the area during the evening.
