Fire Weather Planning Forecast for Utah

...STRONG TO SEVERE STORMS, ELEVATED FLASH FLOOD RISK TODAY...
.BROADCAST DISCUSSION...Scattered showers and thunderstorms
will bring strong to severe storms focused over northern and
central Utah this afternoon, while scattered thunderstorms
capable of heavy rains will bring an elevated flash flooding
threat to portions of northern and central Utah with an emphasis
on southern Utah. An approaching system will bring cooler
temperatures and more widespread wetting rain chances moving
forward through early next week.
.DISCUSSION...Active weather continues today with strong to severe
thunderstorms developing this afternoon across northern and
central Utah with a flash flooding threat also developing this
afternoon across central and southern Utah. Regarding the severe
threat further north, wind gusts in excess of 58-70mph and hail to
around 1" are expected this afternoon with any of the stronger
storms that form. Across southern Utah, monsoonal moisture
continues to surge north bringing an attendant flash flooding
threat to the area through at least Monday. While storm
development across southern Utah may be somewhat muted Sunday
afternoon, Monday appears somewhat concerning regarding rainfall
high rainfall rates and amounts. Regardless, a wetting rain is
expected across the entirety of Utah through early next week.
Following this active patter, a drying and cooling trend will take
place as most showers and thunderstorms appear to remain confined
to the higher terrain at this time. Temperatures will run roughly
5F below seasonal normals with RH approaching normals around mid-
week.
***Thunderstorms imply strong, gusty and erratic winds***
***All winds are 20 foot, 10-minute averages***
