KEY MESSAGES

- High pressure will bring historically warm weather for March by the middle of the upcoming week, with temperatures approaching 30F above seasonal normals continuing into the first part of the upcoming weekend.

DISCUSSION

Winds have weakened in the post frontal environment across most of the area, although gusty winds 20-30 mph will remain across portions of Castle Country and the western Uinta Basin (primarily during the day). Temperatures are dramatically colder than the past several days with most locations expected to get near to below freezing, aside from lower Washington county and lower elevations portions of Zion.

Temperatures will quickly rebound over the next several as a prominent ridge begins to build across the west. In fact, the heights underneath this ridge will approach 595 dm which could rival the most anomalous heights seen not only in March, but for any month from November to March. We are talking about shattering all-time record highs for the month of March as we get to the end of the week and into the weekend. Just for context, our highest forecast temperature this week for St. George is 97 degrees on Thursday AND Friday. This would beat the previous March record high temperature by 6 degrees (previous record being 91). In fact, St. George will be in the 90s for at least 5 days (Wednesday- Sunday). St. George has only ever gotten into the 90s twice in March dating back to 1893. As for KSLC, temperatures are forecast to be in the 80s Friday and Saturday which would break the record for earliest 80 on record (previous being 3/31) and warmest temperature recorded for the month if we get to 81+.

Cooler air starts to slowly creep into the CWA by Sunday as the jet stream to our north starts to sag further south and flatten the ridge. There is still little in the way of moisture until at least the middle of next week. So until then it will be dry and stable with record high temperatures.

REST OF UTAH AND SOUTHWEST WYOMING

Diurnal winds will settle into the area...with mainly terrain driven winds through the day Monday.
