A trough exiting to our east today will maintain temperatures
slightly below average. Weak ridging aloft rebounds Saturday and
Sunday bringing a return to warm, near normal temperatures. A
shortwave moving through the Northern Rockies late Sunday will
bring slightly below average temperatures to start next week.


.SHORT TERM (Through 00Z Tuesday)...
A weak cold front continues to work its way through northern Utah
early this morning. A very narrow band of cloud cover with some 
isolated showers along it have developed along the front this 
morning from near SLC into southwest WY. This front will stall 
near central UT today where it weaken in place today and tonight. 
Meanwhile some residual moisture along the boundary will result in
a few isolated to widely scattered showers and thunderstorms over
the high Uintas and points east. Otherwise expect a dry day with 
much more sunshine than yesterday. Temperatures will run a fair 
bit cooler today behind the cold front across northern Utah, with 
highs about 5 degrees below average.

Weak ridging will rebound Saturday and Sunday behind the departing
trough to our east. This will continue the dry conditions with
temperatures returning very near seasonal values. By Sunday, an
active northern stream jet over the Canadian Rockies allow a
shortwave transiting to our north to suppress our weak riding
Sunday night into Monday, while pushing another dry, weak cold
front in northern Utah. Winds will likely see an uptick on Sunday
ahead of the cold front, while temperatures will return back to
values about 5 degrees below average across northern Utah behind
the front on Monday.

.LONG TERM (After 00Z Tuesday)...
High pressure is expected to rebuild over the forecast area for 
the middle to latter part of the upcoming week, keeping 
temperatures near or just above seasonal normals. The ridge axis 
is expected to position itself just east of the area beginning 
Wednesday, allowing moisture to gradually make its return through 
the balance of next week. Because of this, have indicated 
increasing cloud cover and a slow increase in POPs through day 


The SLC terminal will see VFR conditions throughout the day with 
decreasing clouds. Northwest winds will prevail through the 
afternoon hours, but will be light and variable or light 
southeasterly at times through about 15Z. 


WY...Red Flag Warning until 8 PM MDT Friday for WYZ277.



LONG TERM...Traphagan
