Area forecast discussion
National Weather Service Salt Lake City Utah
822 PM MDT Friday Oct 9 2015
Synopsis...high pressure aloft will remain over Utah through
Saturday. A weather disturbance moving east through the northern
rockies will nudge a dry cold front through the northern half of
Utah Sunday. High pressure will return to the Great Basin through
Discussion...a strong ridge aloft remains centered just to our
west this evening with a dry and mild airmass over Utah. A band of high
clouds spread across the northern County Warning Area this afternoon blocking enough
sunlight to prevent highs from getting any warmer than yesterday
while the south managed to edge a few degrees higher. These high
clouds are heading south this evening and should move out of the County Warning Area
after midnight leaving clear skies.
The ridge axis is still forecast to shift east tomorrow with
increasing southwesterly flow aloft locally surfacing in the western valleys.
This plus less cloud cover should send temperatures 5-10 degrees warmer
The weak dry cold front is still forecast to spread somewhat
cooler air into northern Utah sun that will probably be good for 5-10
degrees cooling and some enhanced westerly afternoon winds over the
mountains and southwestern Wyoming but thats about it.
Ridging returns Monday and persists through Thursday keeping temperatures well above
normal and the County Warning Area dry. No updates planned.
Aviation...winds at the slc terminal will shift to the southeast
