.DISCUSSION...
Issued at 947 PM MDT Sat Jun 13 2026

An upper level ridge is beginning to establish itself over much of
the West as we end the weekend and move into the work week. The San
Juans have the most favored chance (60-70%) for showers and storms
Sunday, but there is a possibility for dry thunderstorms to
materialize, posing a threat for new fire starts. Accumulations, if
any, from this system appear to be minuscule. Some HiRes model
guidance depicts a slight chance (20%) for showers and storms to
scatter northward towards the I-70 corridor and in portions of
eastern Utah for Sunday as well. More cloud coverage is anticipated
Sunday which will drop daytime highs a few degrees below Saturday,
but still above normal. Critical fire weather conditions appear to
be mostly localized Sunday, therefore no products have been issued.

HOT, DRY, WINDY WORK WEEK:

The aformentioned ridge begins to propagate further west as the work
week begins, prolonging hot, dry, windy conditions. Critical fire
weather conditions are projected to expand on Monday, becoming
increasingly widespread on Tuesday, and peaking in coverage by
Wednesday. Wednesday also appears to be the hottest day of the week,
with temperatures 10-15 degrees above normal, with triple digits
possible in some locations. If recreating outdoors, stay hydrated
and take frequent breaks in the shade. Guidance suggests very little
chances for precipitation throughout the week and the continuation
of daytime highs 5-10 degrees above normal.
