Area Forecast Discussion
National Weather Service Salt Lake City UT
940 AM MDT Sat Mar 18 2017

.SYNOPSIS...A very mild southwest flow will prevail today. A more
active pattern is expected to develop for next week.


.DISCUSSION...Record challenging/breaking warmth today. For many
areas it will not be a question of if we will break the old
record but at what time we will break the record. The current
forecast of 80 degrees at SLC will not only crush the old record
of 72 for the date, but will also be the earliest and only the
second time in recorded history that SLC has reached 80 in the
month of March (the last time was March 31 in 2012). The limiting factor
on how warm we will reach will have a lot to due with the amount
of cloud cover. There is going to be variable amounts of high
clouds today and if the clouds thicken just at the time of best
heating then we may not reach 80 here at SLC or your max temp
forecast in other parts of the CWA. However, if there is
significant sunshine late this afternoon, then the forecast max
temperatures should be right on target.

Gusty southerly winds may be the only downside to such an

Current package looks on track so no updates needed.


.AVIATION...The SLC terminal will see VFR conditions throughout the
day with some high clouds. Southerly winds are expected throughout
the day, becoming increasingly gusty this afternoon. There is a 20
percent chance of a late wind shift to the northwest between 21Z and
