Fire Weather Planning Forecast for Utah
National Weather Service Salt Lake City UT
441 AM MDT Sat Sep 19 2026
...ISOLATED THUNDERSTORMS ACROSS FAR NORTHERN AND EASTERN UTAH,
DRIER SUNDAY AND MONDAY...
.BROADCAST DISCUSSION...A weak cold front continues to push
through Utah serving to dry out much of the state. Isolated to
scattered thunderstorms are forecast to develop across far
northern and eastern Utah this afternoon before chances for
precipitation drop to near zero Sunday and Monday.
.DISCUSSION...A cold front is currently making its way through the
state, keeping conditions dry across much of northern, central,
and southern UT. However, for areas across eastern UT and far
northern UT near the ID border, isolated to scattered
thunderstorms are expected to develop this afternoon and subside
around sunset. Thunderstorm intensity is not forecast to reach
severe thresholds with todays storms featuring frequent lightning,
gusts to around 40mph, and perhaps a few instances of small hail.
Starting Sunday, the cold front will have pushed through the area
in its entirety with drier and cooler air filling in its wake
keeping chances for precipitation near zero through Monday.
Starting early Tuesday, an active pattern looks to redevelop with
winds clocking to southerly, enabling moisture to return to much
of the state increasing chances for showers and thunderstorms once
again through the remainder of the week.
***Thunderstorms imply strong, gusty and erratic winds***
***All winds are 20 foot, 10-minute averages***
