Area forecast discussion
National Weather Service Salt Lake City Utah
841 PM MDT Monday Apr 27 2015
Synopsis...high pressure will remain in place through Wednesday.
A weak cold front will sag into northern Utah on Thursday.
Discussion...an upper ridge remains centered over the West Coast
states this evening with a northerly flow over the County Warning Area. Low level
moisture in the form of stratocumulus has lingered over mainly
higher terrain into the evening but expect this to dissipate by
midnight as the upper ridge moves closer and subsidence
increases over the area overnight.
The ridge continues to shift slowly east Tuesday with additional
airmass warming. Some shallow convection is again forecast for the
higher terrain across the County Warning Area Tuesday afternoon but the vertical extent is
forecast to be insufficient to generate thunder...or even much if
any rain for that matter.
The ridge shifts east Wednesday and the airmass warms a little more
sending the high temperature at slc to around 80. Convection may be a
little better developed Wednesday afternoon over the uintas and northwestern mountains
but should remain very isolated at best.
A weak surface boundary sags into northern Utah Thursday and becomes the focus
for a slight increase in convection.
No updates planned this evening.
Aviation...light southeast winds will prevail at the kslc
terminal after about 04z. Expect a return to a Northwest Lake
breeze around 19z on Tuesday.
