Synopsis An upper low over nevada will slowly track across
utah late tonight through Sunday, keeping cool and in some areas
wet weather in place. Another upper low will likely impact utah
midweek.

Discussion An upper low is noted in satellite imagery rotating
into far southwest utah this evening. The associated 700mb
baroclinic zone is noted in objective analysis oriented north-
south across eastern utah northward into southwest wyoming. Ahead
of the upper low, convection has increased along this baroclinic
zone over the past hour or two from emery county northward into
the uinta basin. Meanwhile, an expanding area of cooling cloud
tops with a region of upper diffluence has maintained a persistent
region of stratiform precipitation across northern utah including
the wasatch front. Snow levels have at times dropped to near 6000
feet east of the wasatch crest.

As the upper low lifts north-northeastward through central and
eventually northern utah overnight through the day Sunday,
anticipate widespread valley rain and mountain snow to continue
across this area, with a gradual decreasing trend from south to
north as the event progresses. May see a temporary break late
night into the early morning hours Sunday along the wasatch front
as the flow aloft temporarily becomes easterly, however wrap
around precipitation on the back side of the passing low should
quickly fill back in by mid to late morning. Snow levels are
expected to generally remain in the 6000-6500 foot range through
the day Sunday, with significant accumulating snow remaining above
7kft.

Updated the going forecast to adjust for convective trends
earlier, as well as to increase pops across the north overnight
through the day Sunday. Going wsw looks in good shape, although
will need to keep a close eye on southwest wyoming where
precipitation has already turned over to snow earlier than
expected.

Aviation Cigs at kslc are expected to fluctuate between high
end MVFR and low endVFR through the overnight hours. May see cigs
lift above 4 kft late tonight for a time, before lowering again by
mid morning as rain sets back in. Visibility should remainVFR but
may fall into the 4-5sm range within heavier bands of rain.

Southerly winds are expected to redevelop by 05z, although there
is a 30 percent chance they persist through the overnight hours
before becoming northwest Sunday morning.

These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
