Synopsis A warming and drying trend will take place across the
area through Friday. Moisture will increase again from the south
over the weekend.

Discussion Pretty quiet across the forecast area this morning
per visible satellite imagery, with some dissipating cloud cover
across the book cliffs and castle country of eastern utah. Water
vapor analysis shows the upper low sagging over southern nevada
while subsident air moves into northwest utah, further stretching
out a deformation zone across southern utah. This will be the
favorable area for any afternoon convection to develop, although
any that does develop should be low in coverage. Precipitable
water values this morning across southern utah are running 0.6 to
0.7 inches, while northern utah is 0.5 to 0.6 inches. Kept pops
confined to the terrain, with a very slight increase, as this
will be the best lift mechanism to initiate development. Light
steering flow aloft points to low chances of any convection
drifting off the terrain. Overall, little changes made to the
morning forecast package. The warming and drying trend will remain
in place going into the weekend. Previous extended discussion
below.

Previous discussion (issued 441 am mdt Thursday) Finally
starting to see better agreement among the global models with
regard to the extended period. The ridge over the region is
expected to flatten during the day Saturday as a trough moves over
the top of it over canada. This flow will keep the airmass on the
dry side, and should limit afternoon and evening convection to
the higher terrain.

On Sunday, the trough off the california coast is expected to close
off and strengthen, shifting the flow over the forecast area to a
more southerly direction. GFS has been consistent in indicating that
this flow will draw monsoonal moisture northward for the early to
middle part of the upcoming week. This combined with weak shortwaves
moving through the flow will increase coverage of convection.

Previous runs of the ec kept the forecast area mostly dry during
this period due to a different placement of the low, which caused
the flow to tap into a drier airmass. Though the latest ec is still
drier than the gfs, especially over western utah, it is noticeably
more moist than previous runs, so have raised afternoon and evening
pops Monday through day seven.

Temperatures look to remain fairly consistent through the extended
period with maxes running near to a few degrees above seasonal
normals.

Aviation The slc terminal will seeVFR conditions throughout the
day. Southeast winds are expected to shift to the northwest between
18z and 20z.

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.
