KEY MESSAGES

- Near record temperatures will remain across southern Utah with a return to record temperatures across central and northern Utah Tuesday and Wednesday.

- Another brief cool down Thursday and Friday before more heat builds for the weekend.

DISCUSSION

A cooler airmass is in place, temporarily, for today. Highs today are going to be about 15 degrees cooler than yesterday, for northern Utah. This cooler airmass has struggled to penetrate into southern Utah where highs are similar to what they were yesterday (near record-breaking). Temperatures across northern Utah will only rise a few degrees for Monday before a more dramatic warm-up takes shape for the middle of the week.

This airmass quickly retreats as the historic ridge builds back to the north with temperatures back into record breaking territory by Tuesday. Highs on Tuesday will be approaching 80 degrees once again across the Wasatch Front with low 90s across lower Washington county. The hottest day will come on Wednesday where there is currently a 75% chance of reaching 85F and breaking the March all-time record warmest temperature (84F) that we just set yesterday!

A cooler airmass will move into the region by Thursday as a shortwave crossing the Great Basin flattens the ridge. There are still some EC members (~50%) that do bring some mountain showers to northern Utah on Thursday with the shortwave passage, however this scenario is not supported by any GFS or CAN members so PoPs for the mountains remain <15%. Again, this airmass does not result in much of a temperature moderation for southern Utah. While it does bring some cooler air to northern Utah for Thursday and Friday, high temperatures will still remain ~10 degrees above normal for this time of year. Temperatures then return to the mid 70s across northern Utah by next weekend as we just can't seem to shake this stubborn ridge.

The next chance for precipitation remains towards the end of the month as ~40% of ensemble members continue to show precipitation by March 30th, but there is some timing discrepancies that will need to be ironed out amongst the members as some range as late as April 3rd with the arrival of any precipitation.

REST OF UTAH AND SOUTHWEST WYOMING

Northerly winds will gradually relax, becoming light and terrain-driven overnight, particularly after 03z. Breezy westerlies will pick up again after 18z. Expect VFR conditions and FEW-SCT high clouds.
