Scientific Forecaster Discussion
Area forecast discussion
National Weather Service Salt Lake City Utah
848 am MDT Thursday Oct 8 2015
Synopsis...a ridge of high pressure will build over the eastern
Great Basin through Friday...then flatten a bit late in the
weekend as a weak upper level disturbance scrapes across the
northern rockies. A weak cold front in association with the
disturbance will sag into northern Utah on Sunday.
Discussion...the synoptic pattern at 500mb features a cutoff low
over northwestern Mexico and a ridge extending from the eastern
Pacific into the Great Basin. This semi-blocking pattern will
contribute to quiet weather the next few days. Today...the only real
forecast challenge is middle-level cloud cover as a series of cloud
bands rotate eastward on the northern flank of the ridge. These will
most prominiently impact the northern County Warning Area but will diminish through
the day...skies will transition from mostly to partly cloudy.
No changes were made aside from minor adjustments in cloud cover
and temperature over the north.
Aviation...ceilings will remain above 10000ft today. Winds will
shift to north-northwest after 17z and remain less than 10kts before returning
to south-southeast this evening.
