Synopsis...dry weather and unseasonably warm temperatures can be
expected for much of the area through late this week. A low
pressure system will move across the region this weekend with
increasing winds and a downward trend in temperatures expected.


Discussion...high pressure will build over the southwestern
United States through the middle of the week continuing to bring
warm and mostly dry weather to the area. A trough and cool front
passing through Utah will result in locally breezy north winds
tonight through Wednesday morning. Otherwise, winds will generally
be light through Thursday. Temperatures will run between 10 to 15
degrees above late April averages. The warmest temperatures of
the week are expected to be on Thursday afternoon. Just enough
instability may be present for an isolated afternoon
shower/thunderstorm Thursday over the highest peaks of the eastern

Friday will see breezy southwest winds develop, as well as
temperatures dropping a few degrees as a Pacific trough begins to
move inland. Breezy to windy conditions and closer to average
temperatures will persist through the weekend and into the early
part of next week as a broad trough of low pressure develops over
the west. Confidence is low on the details of any particular
feature and its weather impacts beyond Saturday, due to
differences in model solutions. Overall, expect a breezy and
unsettled pattern.
