Synopsis A weak upper level disturbance will move across
northern utah today. Another storm system will move into
southwest utah Sunday night and spread rapidly into northern utah
by Monday and remain over the area through Tuesday.

Short term (through 00z Wednesday) A very weak upper level
disturbance appears to be setting off isolated showers across
northern utah overnight which may linger into early day light
hours this morning but most valleys should only receive trace
amounts of rain. Due to the moist air mass in place, partly cloudy
skies over central and northern utah and southwest wyoming will
allow enough heating to support isolated showers and thunderstorms
over the valleys and scattered showers and thunderstorms over the
mountains by afternoon. Temperatures will warm to within about 5
degrees of normal, which will feel considerably warmer due to the
recent well below normal days.

Dry southwest flow will prevail across most of the region Sunday,
but the next trough will be impacting the western valleys already
by afternoon with gusty southerly winds. In addition, the remnants
of a weak upper level trough will swing across the region Sunday which
will likely bring a veil of high clouds. The core of this next
trough will move into southwest utah Sunday night and across
southern utah Monday. The brunt of the precipitation will be
across southern utah through Monday, but spokes of energy wrapping
around the circulation will bring widespread precipitation across
northern utah especially later Monday into Tuesday. Temperatures
will once again fall to 10-20 degrees below normal Monday but then
slowly moderate Tuesday.

Snow levels will drop to near 7000 ft over southwest utah Monday
morning with the passage of the coldest 700mb temps of near -4 to
-5c degrees. Snow levels will lower to near 8000 ft across the north.

Various spokes of energy will rotate southward across utah
Tuesday in the wake of the parent low as it moves into colorado.

Scattered showers seem to be most likely result with areas of
likely showers, mainly over the mountains. Only the extreme
southern portion of utah is expected to escape the showers by
Tuesday due to downsloping flow.

Long term (after 00z Wednesday) A baggy trough situated over the
great basin through the end of the week will continue the unsettled
weather pattern to end out the week. Of note, temperatures will
begin an upward climb to near seasonal normal as the weekend

The flow aloft will shift from the northwest on Wednesday to
southwest by Thursday as the elongated trough stretches farther into
the desert southwest. Weak flow aloft and no jet stream to mention,
however small vorticity advection pockets will provide the needed
lift to support diurnal showers and thunderstorms each day. Moisture
will be present (6-8 g kg mixing ratios) and the upper level
divergence signature is paired with a broad area of instability
increasing in coverage each afternoon from mid-week through the
weekend. Overall, nothing stood out in the extended forecast as a
pattern change, however the overall trough does seem weaker so
perhaps this is a nod to an opportunity for high pressure
to begin building farther to the east in the far extended.

Aviation Southeast winds are in place at the kslc
terminal, and will become gusty out of the south by 17z-18z.VFR
conditions expected through the valid TAF period. There is a 30
percent chance that a nearby shower lowers ceilings below 8000
feet between 18z and 02z.

Fire weather Instability showers will continue across the northern
valleys and the central and northern mountains today with finally
a mostly dry day statewide Sunday. Min rh values will bottom out
on Sunday with 20-30% range over western valleys and 15-25% range
across the south and eastern valleys. Sustained winds of 10-20 mph
will accompany this somewhat dry period, but min rh values will
come right back up to the 30-50% range Monday and Tuesday before
slowly lowering through the end of the week. Additional 0.25 to
0.50 will occur in most areas through Tuesday with local amounts
over an inch possible with several inches of snow above 8000 ft.

These have not been checked for accuracy and in many cases have not even been read by anyone associated with I have no idea of they are useful or accurate, I leave that to the reader. 2) Articles others have written and submitted. If you have questions on these, please contact the author. 3) Articles that represent my personal opinions. These are intended to promote thought and for entertainment. 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 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.
