.KEY MESSAGES...

- High pressure will bring historically warm weather for March
  through Saturday. Daytime max temperatures will challenge
  monthly maximum temperature records as they approach 30 degrees
  above seasonal normals.

- A dry cold front will bring a brief cooling trend Sunday,
  though daytime highs will remain 10 to 15 degrees above normal.

- A return to near record temperatures is expected early next week
  as high pressure returns to the region.

.DISCUSSION...Strong high pressure still resides over the Desert
Southwest, resulting in the anomalously warm, record-breaking
temperatures we`ve experienced already. As this ridge continues to
nudge northward, temperatures today will be largely 2-4 degrees
warmer than yesterday, threatening more records across Utah and
southwest Wyoming. While Salt Lake City fell one degree short of
the March maximum temperature record yesterday, there will be 3
more chances to exceed 80F: today, tomorrow, and Saturday. Many
sites are likely to break daily or monthly records as temperatures
rise another 2-4 degrees heading into Friday.

A dry cold front moving through Sunday will produce a drop in
temperatures, however with such warm antecedent conditions,
temperatures will still be around 10-15 degrees above normal.
Ridging will be quick to return, with temperatures rebounding
early next week through at least Wednesday. Forecast uncertainty
increases after Wednesday, with models trending towards another
dry, but stronger storm system potentially bringing cooler
temperatures later in the work week.
